Etiología y manejo de Phytophthora cinnamomi (Rands) en aguacate en Michoacán.
Provedor de dados: 32
Autores: Fierro Corrales, Dagoberto.
El estado de Michoacán es el principal productor y exportador de aguacate cv. Hass (Persea americana Mill) en México y en el mundo y uno de sus principales problemas fitosanitarios es “la tristeza del aguacatero”, causada por el oomyceto Phytophthora cinnamomi Rands. La tristeza del aguacatero se intentó reducir con un manejo integrado parcial del aguacate (MIA) aplicado durante ocho meses y consistente en dos aplicaciones al suelo de vermicompost, seis de ácido fosfórico y cuatro de Trichoderma harzianum en un huerto del municipio de Uruapan, Mich. El % de raíces infectadas por P. cinnamomi al inicio del experimento (37.9%) bajó a 6.6% en el MIA, en el testigo subió de 26.9% al inicio a 30.2% al final. El crecimiento medio de brotes vegetativos fue de 8.4...

Provedor de dados: 75
Autores: Becker,Walter F; Mueller,Siegfried; Santos,Janaína P dos; Wamser,Anderson Fernando; Suzuki,Atsuo; Marcuzzo,Leandro Luiz.
An alert system for tomato late blight was validated in an Integrated Production System (IP) in the 2006-2007 and 2007-2008 season in Caçador, Santa Catarina State, Brazil. The late blight is a destructive disease and demands 25 or more fungicide sprayings per season in a Conventional Production (CP) System. For the CP area, the chemical control was according to the growers' production systems and consisted of weekly sprays soon after planting. For the IP area, the criterion for the first fungicide spray was according to Machardy (1972) and for subsequent ones according to Wallin (1962), when the disease severity values (DSV) reached eight points. There was a decrease on the fungicide application in the IP, not only in the number of fungicide sprays...

Effect of aqueous neem seed extract via irrigation on larvae of Liriomyza sativae in melon crop
Provedor de dados: 75
Autores: Costa,Ewerton M; Silva,Francisco EL; Araujo,Elton L.
ABSTRACT The leafminer [Liriomyza sativae (Diptera: Agromyzidae)] is one of the main pests of melon crop (Cucumis melo) in the states of Rio Grande do Norte and Ceará. Thus, adopting strategies to control this destructive insect is essential. The aim of this study was to evaluate the effect of aqueous neem seed extract, applied to soil via irrigation, on leafminer larvae, in the melon crop. An experiment was conducted in greenhouse, in completely randomized design, consisting of five treatments (four doses of aqueous neem seed extract: 1; 3; 5 and 10 g/100 mL) and the control consisting only of distilled water and 10 replicates (melon plants). The treatments were applied in a single dose, via soil irrigation. In the first stage of the evaluation, 24 hours...

A review of geminivirus diseases in vegetables and other crops in Brazil: current status and approaches for management
Provedor de dados: 75
Autores: Inoue-Nagata,Alice K; Lima,Mirtes F; Gilbertson,Robert L.
ABSTRACT: Insect-transmitted viruses cause some of the most damaging and economically important diseases of crop plants, especially in tropical and subtropical regions. The geminiviruses, a group of single-stranded DNA viruses with unique twined icosahedral virus particles, are responsible for many of these diseases. Of particular importance are the geminiviruses transmitted by whiteflies (Bemisia tabaci), which are in the genus Begomovirus. This is the largest genus of plant viruses (in terms of number of species), and some are responsible for many devastating diseases in vegetable and fiber crops throughout the world. This review presents the current understanding of begomoviruses, the diseases they cause, and approaches for disease management. An...

To make a meadow it takes a clover and a bee: the entomophilous flora of N.W. Europe and its insects
Provedor de dados: 16
Autores: Ellis, Willem N.; Ellis-Adam, Albertine C.
An analysis of the anthophilous fauna of N.W. Europe is presented, stressing the role plants play for insects. The study is based on some 29,000 relations between about 2,600 insect species and 1,300 plant species (569 genera). The data are derived from our database (“CrypTra”) of biotic relations between Cryptobiota and Tracheophyta, that is based on published sources. It is suggested that a ratio of 2 to 5 anthophilous insect species per entomophilous plant species is the rule in N.W. Europe, where other types of zoophily are virtually absent. A small minority of the plant species/genera play a disproportionally important role as hosts to flower visitors; many of these so-called cornucopian taxa belong to the commonest entomophilous plants in the region,...

Silicon influence on resistance induction against Bemisia tabaci biotype B (Genn.) (Hemiptera: Aleyrodidae) and on vegetative development in two soybean cultivars
Provedor de dados: 82
Autores: Ferreira,RS; Moraes,JC; antunes,CS.
The potential of populations of Bemisia tabaci (Genn.) to become resistant to insecticides has stimulated research into alternative tactics of integrated pest management such as the induction of host-plant resistance. Recent data have shown that silicon can increase the degree of resistance of host plants to insect pests. Therefore the aim of our work was to study the effects of silicon application on the vegetative development of soybean plants and on the induction of resistance to the silverleaf whitefly, B. tabaci biotype B. We performed choice and no-choice tests of oviposition preference on two soybean cultivars, IAC-19 (moderately resistant to B. tabaci biotype B) and MONSOY-8001 (susceptible), with and without application of silicon. Silicon did not...

Ecological modeling and pest population management: a possible and necessary connection in a changing world
Provedor de dados: 82
Autores: Lima,Ernesto A B F; Ferreira,Claudia P; Godoy,Wesley A C.
Ecological modeling is an important tool for investigating dynamic behavior patterns in populations, trophic interactions, and behavioral ecology. However, the ecological patterns that reflect population oscillation trends are often not clearly visible without analytical instruments such as ecological models. Thus, ecological modeling plays a fundamental role in describing demographic processes that are important for population dynamics. Ecological models, besides making possible the visualization of ecological patterns, may also reveal patterns of population persistence in many trophic systems, including prey-predator or host-parasitoid relationships, interactions that are commonly present in integrated pest management programs. In this forum, we present...

Influence of parasitism by Chelonus insularis Cresson (Hymenoptera: Braconidae) on the susceptibility of Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae) to insecticides
Provedor de dados: 82
Autores: Zenner,Ingeborg; Álvarez,Alonso; Barreto,Sandra.
The egg-larval parasitoid Chelonus insularis Cresson is a key parasitoid of the fall armyworm Spodoptera frugiperda (J. E. Smith) during the second field generation in the upper Magdalena River Basin, Colombia. In spite of selection pressure, the higher susceptibility of the second generation fall armyworm larvae to insecticides, compared with that of the first generation, suggests that the parasitism may be responsible for the apparent difference in susceptibility. Parasitized and non-parasitized 2nd-instar larvae of the fall armyworm were tested for susceptibility to chlorpyriphos, methomyl, cypermethrin, and Bacillus thuringiensis in the laboratory, using the leaf dip test. Parasitized larvae were up to 3.93 times more susceptible to chlorpyriphos, 3.71...

Provedor de dados: 82
Autores: Leite,Luís G.; Machado,Laerte A.; Goulart,Roberto M.; Tavares,Fernando M.; Batista Filho,Antonio.
The pathogenicity of six entomopathogenic nematodes was assessed against nymphs of the sugarcane root spittlebug Mahanarva fimbriolata (Fabr.), in the laboratory. The efficiency of the most virulent agent was tested in the field. Seven laboratory treatments were designed with two specimens of the genus Heterorhabditis, three of Steinernema, one specimen of Steinernema glaseri (Steiner), and a control group. In the field, two experiments were conducted. The first experiment involved nine treatments: the control, four treatments with Heterorhabditis sp.

Autores: DALAZEN,G.; CURIOLETTI,L.E.; CAGLIARI,D.; STACKE,R.F.; GUEDES,J.V.C.
ABSTRACT Weeds compete with crops for essential inputs, but they are also important hosts for pests, both during the crop and between crops. Hairy fleabane (Conyza bonariensis) is an important weed growing in both summer and winter crops. The aim of this study was to evaluate the occurrence and population fluctuations of soybean pests using hairy fleabane as an alternative host. Samples of hairy fleabane plants were collected fortnightly over twelve months at two sites (Boa Vista do Incra and São Vicente do Sul) in Rio Grande do Sul state, Brazil. The results showed that hairy fleabane plants provided shelter to important soybean pests, including the pentatomid stink bugs Edessa meditabunda, Piezodorus guildinii, Dichelop sp. and Euschistus heros,...

THE ADOPTION OF IPM TECHNIQUES BY VEGETABLE GROWERS IN FLORIDA, MICHIGAN AND TEXAS
Provedor de dados: 31
Autores: Fernandez-Cornejo,   Jorge; Beach,   E. Douglas; Huang,   Wen-Yuan.
Factors influencing the adoption of Integrated Pest Management (IPM) techniques are studied using survey data from individual vegetable producers from Florida, Michigan, and Texas.  Farmers who adopt IPM tend to be less risk averse and use more managerial time on farm activities than nonadopters.  Adopters are also more likely to operate large, irrigated farms and use more family labor.  Locational factors and the type of crop grown are also influential in IPM adoption.  The analysis uses a logit framework and introduces adopter categories first conceptualized by rural sociologists.

Autores: Hyde,   Jeffrey; Martin,   Marshall A.; Preckel,   Paul V.; Buschman,   Lawrent L.; Edwards,   C. Richard; Sloderbeck,   Phillip E.; Higgins,   Randall A.
While most Corn Belt farmers consider planting Bt corn to control European corn borer, southwestern Kansas farmers must also take into account an array of other insect pests, including corn rootworm, spider mites, and southwestern corn borer. This research uses a decision analysis framework to estimate the expected economic value of Bt corn in southwest Kansas. Mean per acre Bt values ranged from $12.49 to $34.60, well above the technology fee assumed to be $14 per unit, or $5.25 per acre at a seeding rate of 30,000 seeds per acre. The minimum value over all scenarios was $8.69 per acre. Using Monte Carlo simulation, it was shown that European and southwestern corn borer infestation probabilities, expected corn price, and expected pest-free yields are...

ECONOMIC ANALYSIS OF ENVIRONMENTAL BENEFITS OF INTEGRATED PEST MANAGEMENT
Provedor de dados: 31
Autores: Mullen,   Jeffrey D.; Norton,   George W.; Reaves,   Dixie Watts.
Public support for integrated pest management (IPM) is derived in part from concerns over food safety and the environment, yet few studies have assessed the economic value of health and environmental benefits of IPM.  An approach is suggested for such an assessment and applied to the Virginia peanut IPM program.  Effects of IPM on environmental risks posed by pesticides are assessed and society's willingness to pay to reduce those risks is estimated.  The annual environmental benefits of the peanut IPM program are estimated at $844,000.  The estimates of pesticide risks and willingness to pay can be applied elsewhere in economic assessments of IPM.

Optimal Management of Molds in Stored Corn
Provedor de dados: 31
Autores: Yigezu,   Yigezu A.; Alexander,   Corinne E.; Preckel,   Paul V.
Long term storage of corn is becoming more common due to the recent increase in the demand for corn by ethanol plants. Infection of maize kernels by toxigenic fungi remains a challenging storage problem despite decades of research. Experts in storage management propose the use of a combination of preventive and monitoring-based responsive strategies in response to mold risks. In this paper, a stochastic dynamic programming model is solved to determine the expected profitability and optimal combination, timing and intensity of the proposed mold management strategies using farmers’ existing infrastructure. The results show that even with relatively high monitoring costs, maintaining high quality grain using a monitoring based optimal mold management strategy...

For U.S. agriculture to continue along a sustainable path of economic development, further production increases must be generated by technologies that are both profitable and more environmentally benign. In this context, we assess the role of these green or sustainable technologies in steering agriculture along a more sustainable path. However, the lack of markets for the environmental attributes associated with green technologies can limit their development. In addition, simply making a technology available does not mean it will be adopted. Experience with green technologies such as conservation tillage, integrated pest management, enhanced nutrient management, and precision agriculture demonstrates that even when technologies are profitable, barriers to...

Spatial Externalities of Pest Control Decisions in the California Citrus Industry
Provedor de dados: 31
Autores: Grogan,   Kelly A.; Goodhue,   Rachael E.
Predaceous and parasitic insects provide control of important citrus pests. However, many pesticides are toxic to these beneficials. Using California citrus grower survey data, this article tests whether landscape-level use of pesticides affects the presence of and reliance on Aphytis melinus, an important beneficial insect. Results show that landscape-level pesticide use decreases the presence of A. melinus and increases reliance on insecticides. Pesticide use on non-citrus crops has a significant negative effect on the presence of Aphytis melinus, suggesting a cross-crop spatial externality. Our findings illustrate that regulations designed to address cross-crop effects on beneficial insects can increase social welfare.

THE ENVIRONMENTAL EFFECTS OF ADOPTING IPM TECHNIQUES: THE CASE OF PEACH PRODUCERS
Provedor de dados: 31
Autores: Fernandez-Cornejo,   Jorge; Ferraioli,   Jennifer.
The impact of adopting integrated pest management (IPM) techniques is examined for peach producers in eight states accounting for most of the U.S. production.  The method accounts for self-selectivity, simultaneity, and the pesticide demand equations are theoretically consistent with a restricted-profit function.  Biological pest management techniques tend to reduce pesticide use and pesticide toxicity substantially, while pesticide-efficiency techniques (using scouting and economic thresholds) have an increasing effect on pesticide use and toxicity, and cultural techniques have an insignificant effect on pesticide use and toxicity.

Effectiveness of Integrated Pest Management Dissemination Techniques:  A Case Study of Potato Farmers in Carchi, Ecuador
Provedor de dados: 31
Autores: Mauceri,   Maria; Alwang,   Jeffrey Roger; Norton,   George W.; Barrera,   Victor.
Potato farmers in Ecuador rely on chemical inputs to manage pests and optimize yields.  Integrated pest management techniques lower production costs, reduce pesticide exposure, and improve long-term agricultural sustainability.  Public extension does not, however, exist in Ecuador and cost-effective means of communicating complex messages to producers are needed.  We analyze cost-effectiveness of alternative dissemination methods, including farmer field schools (FFS), field days, pamphlets, and word-of-mouth transmission.  Field days and pamphlets have strong impacts on adoption, especially considering their low costs.  FFS are effective, but expensive.  Evidence also indicates significant diffusion from FFS to non-FFS farmers, indicating high...

Provedor de dados: 31
Autores: Ramirez,   Octavio A.; Schultz,   Steven D.
Evaluations of the factors influencing the adoption of agricultural and natural resource management technologies among small farmers in developing countries have been mostly limited to qualitative discussions or simple descriptive statistics resulting in superficial and inconclusive findings. This study introduces the use of Poisson Count Regressions as a statistically appropriate procedure to analyze certain common types of adoption data. It uses them to assess the impact of key socio-economic, bio-physical, and institutional factors on the adoption of integrated pest management, agroforestry, and soil conservation technologies among small farmers in three Central American countries: Costa Rica, Panama, and El Salvador.

Scouting is the most widely used integrated pest management technique adopted by U.S. growers. This study applies an implicit demand formulation of the Lichtenberg-Zilberman damage abatement model to data from a survey of Maryland field crop growers to examine differences in pesticide demand between growers using scouts trained and supervised by extension and those using chemical dealer employees or scouting themselves. The results give partial support to those skeptical of the quality of scouting by farmers themselves and by consultants working for chemical dealers. Soybean growers using extension-trained scouts had significantly lower pesticide demand than those using chemical dealer employees or scouting themselves. However, no significant differences...

Do Pesticide Hazards to Human Health and Beneficial Insects Cause or Result from IPM Adoption?  Mixed Messages from Farmer Field Schools in Nicaragua
Provedor de dados: 31
Autores: Labarta,   Ricardo A.; Swinton,   Scott M.
This paper analyzes the interaction between farmer training in pest management and effects on acute pesticide poisoning and populations of beneficial insects in Nicaragua.   Using farm level data from Nicaraguan bean growers, including graduates of Farmer Field Schools (FFS), other integrated pest management (IPM) outreach methods, and farmers without exposure to IPM, we found that small farmers are influenced by pesticide-related acute illness experiences when adopting IPM practices and making decisions about pesticide use.  However, exposure to IPM extension programs failed to reduce the use of highly toxic pesticides and increased the number of self-reported acute illness symptoms during the most recent bean crop season.  IPM training did result in...

Autores: Resende,Daniela Chaves; Mendes,Simone Martins; Marucci,Rosangela C.; Silva,Alessandra de Carvalho; Campanha,Mônica Matoso; Waquil,José Magid.
ABSTRACT The cultivation of genetically modified crops in Brazil has led to the need to assess the impacts of this technology on non-target species. Under field conditions, the potential effect on insect biodiversity was evaluated by comparing a homogeneous corn field with conventional and transgenic maize, expressing different Bt proteins in seven counties of Minas Gerais, Brazil. The richness pattern of non-target insect species, secondary pests and natural enemies were observed. The results do not support the hypothesis that Bt protein affects insect biodiversity. The richness and diversity data of insects studied were dependent on the location and other factors, such as the use of insecticides, which may be a major factor where they are used.

ABSTRACT  Among the pests of citrus, one of the most important is the red and black flat mite Brevipalpus phoenicis (Geijskes), which transmits the Citrus leprosis virus C (CiLV-C).When a rational pest control plan is adopted, it is important to determine the correct timing for carrying out the control plan. Making this decision demands constant follow-up of the culture through periodic sampling where knowledge about the spatial distribution of the pest is a fundamental part to improve sampling and control decisions. The objective of this work was to study the spatial distribution pattern and build a sequential sampling plan for the pest. The data used were gathered from two blocks of Valencia sweet orange on a farm in São Paulo State, Brazil, by 40...

ABSTRACT: Whitefly Bemisia tabaci (Gennadius) biotype B is the major pest of common bean (Phaseolus vulgaris L.) in Brazil and other countries. Host plant resistance is one of the cornerstones of Integrated Pest Management (IPM), and assessment of cultivars for insect resistance is fundamental to provide farmers options for pest control. This study evaluated common bean resistance to whitefly in the winter and rainy seasons in Jaboticabal, Brazil, and correlated the infestation with climatic factors. The plant part and development period of common bean that are more susceptible to whitefly infestation were also examined for potential use in IPM. Field experiments were carried out using 18 and 19 commercial cultivars in the winter and rainy seasons,...

Biological Control in Brazil: an overview
Provedor de dados: 63
Autores: Parra,José Roberto Postali.
The use of Biological Control methods is on the increase, mainly as a result of the mobilization of human resources in entomology studies since the establishment of graduate programs in this country in the 1960s. This review approaches the retrospective of Biological Control in Brazil in recent decades, with an emphasis on the "culture of applying agrochemicals" adopted by Brazilian growers, which constrains progress in this area. Successful cases of Biological Control have been reported on in Brazil and there are, in fact, excellent programs in place that use insects or entomopathogenic microrganisms for insect pest control. Most of the studies in this area have been published in Portuguese and are, therefore, not readily available internationally....

Provedor de dados: 63
Autores: Ruiz-Cárdenas,Ramiro; Baker,Peter.
The overlap of generations of coffee berry borer (CBB), Hypothenemus hampei (Ferrari) under field conditions in countries like Colombia hinders the construction of life tables by the sampling of natural populations. In this paper, a field methodology to carry out regular measurements of CBB cohorts inside coffee berries of different ages until harvest, both in coffee trees and in infested berries placed on the ground, is developed and used to compare the life history parameters of CBB. Populations with berries at six ages in three experimental stations (without CBB control) and in a commercial farm in Colombia (with chemical CBB control regularly carried out) were used. The duration of the pre-oviposition period as well as the mortality and survival rates...

Provedor de dados: 63
Autores: Ventura,Maurício Ursi; Resta,Claudio Cezar Mariano; Nunes,Daiane Heloísa; Fujimoto,Fabio.
Refinements in trap characteristics may improve ability to monitor and mass-trap beetles. Field assays were conducted in common bean fields to assess responses of Diabrotica speciosa (Germar) to some trap characteristics. Golden yellow plastic cups (750 mL) traps caught more D. speciosa females and males than did clear traps. Carrot slices in Petri dishes baited with Lagenaria vulagaris L. powder (cucurbitacin source - 0.28%) caught more beetles than did dishes with carrot alone. Dispensers for the floral volatile attractant 1,4-dimethoxybenze were also compared. Rubber septa dispenser attracted more beetles than did control (dental wicks saturated with acetone). Captures on dental wick, starch matrix and feminine pad dispensers were intermediate and did...

Provedor de dados: 63
Autores: Gleason,Mark L.; Duttweiler,Katrina B.; Batzer,Jean C.; Taylor,S. Elwynn; Sentelhas,Paulo Cesar; Monteiro,José Eduardo Boffino Almeida; Gillespie,Terry J.
Disease-warning systems are decision support tools designed to help growers determine when to apply control measures to suppress crop diseases. Weather data are nearly ubiquitous inputs to warning systems. This contribution reviews ways in which weather data are gathered for use as inputs to disease-warning systems, and the associated logistical challenges. Grower-operated weather monitoring is contrasted with obtaining data from networks of weather stations, and the advantages and disadvantages of measuring vs. estimating weather data are discussed. Special emphasis is given to leaf wetness duration (LWD), not only because LWD data are inputs to many disease-warning systems but also because accurate data are uniquely challenging to obtain. It is concluded...

Autores: Makni,Hanem; Bouktila,Dhia; Mezghani,Maha; Makni,Mohamed.
Hessian fly, Mayetiola destructor (Say), is a destructive pest of wheat worldwide and an endemic pest in Tunisia. Two natural populations of this insect from the North of Tunisia were evaluated, in the field, for their virulence, based on response developed by bread wheat (Triticum aestivum L.) cultivars carrying H3, H5, H6, H7H8, H11, H13 and H16 resistance genes. H11, H13 and H16 showed a high effectiveness against both populations; therefore, their implication in Hessian fly breeding programs would be of interest. The level of infestation, as well as the yield loss, was assessed, based on the percentage of infested plants and variation in growth parameters due to infestation. The percentage of infested plants, over a 2-yr period in Mateur, averaged...

Provedor de dados: 117
Autores: Souza,Jander R; Carvalho,Geraldo A; Moura,Alexandre P; Couto,Marcelo H.G; Maia,Jader B.
Corn (Zea mays L.) is cultivated in large areas and considered one of the world's major cereal crops. There are several arthropod pests that can reduce its production such as the fall armyworm, Spodoptera frugiperda (J.E. Smith) (Lep.: Noctuidae), which is considered to be the main pest for corn. Fall armyworm is primarily controlled by insecticides. The use of biological control agents to manage this pest is growing with an emphasis on the egg parasitoid Trichogramma pretiosum Riley (Hym.: Trichogrammatidae). Thus, the aim of this research was to evaluate the impact of the following insecticides (g ai L-1) beta-cypermethrin (0.03), chlorfenapyr (0.60), chlorpyrifos (0.96), spinosad (0.16), etofenprox (0.10), triflumuron (0.08),...

ABSTRACT: The major objective of this paper was to assess the impact of the Farmer field school (FFS) training program on the knowledge level of farmers (citrus growers) regarding improved citrus production practices. Distract Sargodha was the targeted research area for this study being the leading producer of citrus in Pakistan. Quantitative data were collected through interview schedule and analyzed through Statistical Package for Social Sciences (SPSS). It was conclude that young people were more tend towards getting training under FFS program than old age farmers. Educated farmers were in majority in FFS farmers while; conversely illiterate farmers were in majority in the category of non-FFs farmers. In category of FFS farmers livestock farming was...

Strawberry fields receive several pesticides spraying and residues in fruits are recurrent. Development and application of methods that avoid applying pesticides mostly during fructification period are imminent needs. Comparison of population of two-sppoted spider mite (TSSM) Tetranychus urticae Koch. in organic and mineral fertilized plants (as used by growers) and treated with alternative products were done. Plants were grown in vessels in a greenhouse infested with local population of TSSM. Extracts of Tephrosia voggeli (Hook), neem oil (Azadirachta indica A. Juss.), and lime sulfur were applied three times against TSSM in ten days intervals. Assessments were done three times after each spraying. Interaction between fertilization and spraying...

ABSTRACT: Natural biological control is one of the major causes responsible for reduction of pest population in agricultural ecosystem. However, natural biological control importance is usually minimized by not being estimated. This study reports the occurrence of Campoletis sonorensis (Cameron, 1886) (Hymenoptera: Ichneumonidae), Archytas marmoratus (Townsend, 1915) and Archytas incertus (Macquart, 1851) (Diptera: Tachinidae) associated with Helicoverpa armigera (Hübner, 1809) (Lepidoptera: Noctuidae). The rate of larval parasitism was up to 41% in structured refuge areas of cotton, without chemical control with insecticides. This study strengthens our knowledge relating to parasitoids associated with natural control of H. armigera in the American...

ABSTRACT: The objective of this study was to evaluate extent of larval period, larval survival (%), food consumption, and pupal biomass of Spodoptera eridania and  Spodoptera frugiperda (Lepidoptera: Noctuidae ) fed on fresh ears of field corn expressing Bt proteins (Cry1F and Cry1F+Cry1A.105+Cry2Ab2). Larvae of Spodoptera spp. survived less than two days when they consumed Bt corncobs and showed 100% mortality. Spodoptera eridania reared on non-Bt corn cobs showed higher larval development (21.6 days) than S. frugiperda (18.4 days) and lower viability (56.4% and 80.2% for S. eridania and  S. frugiperda , respectively). A higher amount of corn grains was consumed by S. eridania (5.4g) than by S. frugiperda (3.9g). In summary, this study demonstrated that...

Thrips of the genus Frankliniella cause significant reduction on grape production. Little is known about its decision making approach in integrated pest management and information on thrips injuries to the vine is scarce, hindering the control of this pest. This study aimed to determine the species of thrips and injuries that cause damage to berries in seedless grapes clusters. The trial was conducted in an area cultivated with Vitis vinifera L., variety Thompson Seedless, using a randomized block design with five treatments and four replications. The treatments consisted of artificial infestation (zero, two, four and eight thrips per inflorescence), and treatment determined by the monitoring system of the grower. Each replication consisted of three plants...
