The ectoparasite mite Varroa destructor Anderson and Trueman in southeastern Brazil apiaries: effects of the hygienic behavior of Africanized honey bees on infestation rates
Provedor de dados: 25
Autores: Pinto, Fábio de Assis.
No Brasil, o ácaro ectoparasita de abelhas Varroa destructor Anderson e Trueman (Acari: Varroidae) se mantém em índices de infestação baixos, não causando grandes prejuízos. Todavia com a introdução e possível predominância de um novo haplótipo (K) do ácaro, geralmente encontrado em regiões com altas taxas de infestação (TI), faz-se necessário o monitoramento e seleção de colônias resistentes à praga, evitando problemas futuros. Vários fatores são relacionados como possíveis responsáveis pela dinâmica de infestação do ácaro, dentre os quais se destaca o comportamento higiênico (CH). Nesse contexto buscamos avaliar o CH de abelhas africanizadas Apis mellifera L. (Hymenoptera: Apidae) correlacionando com as TI do ácaro em apiários de dois municípios do...

Grasshopper Population Ecology: Catastrophe, Criticality, and Critique
Provedor de dados: 7
Autores: Lockwood, Dale R; Colorado State University; dale.lockwood@colostate.edu; Lockwood, Jeffrey A; University of Wyoming;.
Grasshopper population dynamics are an important part of the North American rangeland ecosystem and an important factor in the economies that derive from the rangeland. Outbreak dynamics have plagued management strategies in the rangeland, and attempts to find simple, linear and mechanistic solutions to both understanding and predicting the dynamics have proved fruitless. These efforts to ground theory in a correspondence with the &amp;#8220;real&amp;#8221; world, including whether the population dynamics are ultimately density dependent or density independent, have generated abundant heat but little light. We suggest that a pragmatic approach, in which theories are taken to be &amp;#8220;tools&amp;#8221; rather than competing claims of truth, has greater...

Autores: Lin,Chien-Yih; Wu,Der-Chung; Yu,Jih-Zu; Chen,Bing-Huei; Wang,Chin-Ling; Ko,Wen-Hsiung.
Development of alternative methods for pest management is needed with the increased concern for adverse effects of pesticides for human health and the environment. The main goal of our study was to test the oil from seeds of sugar apple (Annona squamosa), an edible tropical fruit for pest control. The oil pressed out of seeds was as effective in controlling the silverleaf whitefly, Bemisia argentifolii Bellows &amp;amp; Perring (Homoptera: Aleyrodidae), infesting leaves of tomato plants in greenhouse conditions as the recommended insecticide, with the advantage of not being phytotoxic. When observed with a scanning electron microscope, the seed oil caused whitefly nymphs to shrink and detach from the leaf surface. Sugar apple seed oil was also very...

Spatial forecasting of red palm mite in Brazil under current and future climate change scenarios
Provedor de dados: 86
Autores: Navia,Denise; Hamada,Emília; Gondim Jr.,Manoel Guedes Correa; Benito,Norton Polo.
Abstract: The objective of this work was to predict the spatial distribution of the red palm mite, Raoiella indica (Acari: Tenuipalpidae), in Brazil under current and future climate change scenarios. A mapping method of species distribution based on the geographic information system (GIS) was used. The maps were constructed taking into account ranges of favorability for temperature and relative humidity. Favorability levels were defined considering the available information on pest biology and population dynamics. To characterize the current climatic conditions, information was referenced to the climate normal from 1961 to 1990. Future scenarios for the models were the A2 and B1 gas emission scenarios from the Intergovernmental Panel on Climate Change,...

Predicting the occurrence of alate aphids in Brassicaceae
Provedor de dados: 86
Autores: Cividanes,Francisco Jorge; Santos-Cividanes,Terezinha Monteiro dos.
The objective of this work was to predict the occurrence of alates of Brevicoryne brassicae, Lipaphis erysimi, and Myzus persicae (Hemiptera, Aphididae) in Brassicaceae. The alate aphids were collected in yellow water traps from July 1997 to August 2005. Aphid population peaks were predicted using a degree‑day model. The meteorological factors, temperature, air relative humidity, rainfall, and sunshine hours, were used to provide precision indexes to evaluate the best predictor for the date of the first capture of alate aphids by the traps. The degree‑day model indicated that the peak population of the evaluated aphid species can be predicted using one of the following biofix dates: January 1st, June 1st, and the date of the first capture of the alate...

GENETICALLY ENGINEERED CROPS FOR PEST MANAGEMENT IN U.S. AGRICULTURE
Provedor de dados: 31
Autores: Fernandez-Cornejo,   Jorge; McBride,   William D.
Adoption of genetically engineered crops with traits for pest management has risen dramatically since their commercial introduction in the mid-1990's.  The farm-level impacts of such crops on pesticide use, yields, and net returns vary with the crop and technology examined.  Adoption of herbicide-tolerant cotton led to significant increase in yields and net returns, but was not associated with significant changes in herbicide use.  On the other hand, increase in adoption of herbicide-tolerant soybeans led to small but significant increases in yields, no changes in net returns, and significant decreases in herbicide use.  Adoption of Bt cotton in the Southeast significantly increased yields and net returns and significantly reduced insecticide use.

Autores: Chudleigh,   Peter D.
Project PHT/1990/035, ‘Integrating Grain Protectants into Storage Pest Management’ was supported by ACIAR for nearly four years from 1992 to 1995. The project was based in China and Australia. Project activity within Australia included the further enhancement of an expert system that had been developed by CSIRO. Three main activities took place within the project in China: assessing the extent of resistance to the most commonly used grain protectant, malathion; determining the rates of fenitrothion and deltamethrin that might be used under Chinese storage conditions in order to improve the range of protectants available for Chinese grain storage; and adaptation for, and extension of, an Australian expert system in China. Resistance to malathion was...

Autores: Harper,   Jayson K.; Mjelde,   James W.; Rister,   M. Edward; Way,   Michael O.; Drees,   Bastiaan M.
The rice stink bug is a major pest of rice in Texas, causing quality related damage.  The previous threshold used for assisting in rice stink bug spray decisions lacked flexibility in economic and production decision variables and neglected the dynamics of the pest population.  Using stochastic dynamic programming, flexible economic thresholds for the rice stink bug were generated.  The new thresholds offer several advantages over the old, static thresholds, including increased net returns, incorporation of pest dynamics, user flexibility, ease of implementation, and a systematic process for updating.

Ecological engineering: a new direction for agricultural pest management
Provedor de dados: 31
Autores: Gurr,   Geoff M.; Wratten,   Steve D.; Altieri,   Miguel A.
Ecological engineering has recently emerged as a paradigm for considering pest management approaches that are based on cultural practices and informed by ecological knowledge rather than on high technology approaches such as synthetic pesticides and genetically engineered crops (Gurr et al. 2004a). This article provides a brief summary of ecological engineering for arthropod pest management and contrasts it with its controversial cousin, genetic engineering. The development of ecological engineering is explored, ranging from a simple first approximation that diversity is beneficial, to contemporary understanding that diversity can have adverse effects on pest management. This requires that the functional mechanisms that lead components of biodiversity to...

Re-examining the economic options for import risk assessments
Provedor de dados: 31
Autores: Adamson,   David; Cook,   David C.
The economic impacts of altering quarantine policies are divided into two main areas: trade evaluations, utilising a partial equilibrium approach to determine the benefits of market liberalisation; or pest management economics, used to determine the on-ground impacts of introduced species. This paper rationalises why these approaches need to be brought together within the policy framework of import risk assessments to provide a greater understanding of the benefits and risks from market liberalisation.

Early-warning systems for plant diseases are valuable when the systems provide timely forecasts that farmers can use to inform their pest management decisions. To evaluate the value of the systems, this study examines, as a case study, USDA’s coordinated framework for soybean rust surveillance, reporting, prediction, and management, which was developed before the 2005 growing season. The framework’s linchpin is a website that provides real-time, county-level information on the spread of the disease. The study assesses the value of the information tool to farmers and factors that influence that value. The information’s value depends most heavily on farmers’ perceptions of the forecast’s accuracy. The study finds that the framework’s information is valuable...

Provedor de dados: 94
Autores: Monteiro,Lino Bittencourt; Souza,Alexander; Argenton,Jeferson.
The oriental fruit moth, Grapholita molesta Busck, and fruit flies, Anastrepha fraterculus L., are the important apple pests under Subtropical climate in Southern Brazil, and control is normally accomplished with insecticides. An alternative strategy for the control of G. molesta is mating disruption, through the use of pheromones. Mating disruption strategies using a low density of dispensers (20) per hectare were tested in comparison with conventional pesticides for control of G. molesta in commercial Gala apple orchards in Fraiburgo, SC, for a period of five years. The average field efficiency period of mating disruption formulation over five years was 113 days. In this period the mating interruption index on mating disruption plots was 84.8% over five...

Provedor de dados: 100
Autores: Pino,Oriela; Sánchez,Yaíma; Rojas,Miriam M.
This review covers the historical use of plant secondary metabolites in agricultural practices in Cuba and their potential in pest management. The Cuban flora has not yet been fully studied as a source of pesticides, partly due to its great diversity. Nevertheless, up to date, several plants are used by Cuban farmers as repellents and/or as raw material for the preparation of botanical pesticides in an artisan manner, and more than 60 plants have demonstrated their pesticidal activity under laboratory, semicontrolled and field conditions. Meliaceae, Asteraceae, Fabaceae, Solanaceae, Clusiaceae, Piperaceae, Lamiaceae, Apiaceae, and Mirtaceae are among the most important involved plant families. From the chemical point of view, promising results have been...

The pest greenbug Schizaphis graminum (Rondani) (Hemiptera: Aphididae) stands out among the factors limiting Brazilian wheat production. Chemical control is predominant in aphid management making the production dependent on insecticides. The effect of silicon and previous infestation with aphids on the induction of resistance to the greenbug was evaluated in wheat plants. Treatments consisted of control; fertilization with calcium silicate; plant infestation with aphids; fertilization with calcium silicate + plant infestation with aphids. A free-choice preference test was performed 35 days after seedling emergence; the aphid's intrinsic rate of population increase (r m) was also determined, and the activities of three enzymes (peroxidase,...

Advances in induced resistance by natural compounds: towards new options for woody crop protection
Provedor de dados: 63
Autores: Llorens,Eugenio; García-Agustín,Pilar; Lapeña,Leonor.
ABSTRACT: The activation of defensive responses of plants is a promising tool for controlling pests in conventional agriculture. Over the last few years, several compounds have been studied to protect crops from pests, without displaying direct toxicity for pathogenic organisms. These compounds have the ability to induce a priming state on the plants that results in resistance (or tolerance) against subsequent infection by a pathogen. In terms of molecular response, induced plant defense involves a broad number of physical and biochemical changes such as callose deposition or phenolic compounds, activation of salicylic and/or jasmonic acid pathways or synthesis of defense-related enzymes. Despite the large number of studies performed to ascertain the...

Autores: SILVA,ANTONIO S.; MOTA,THIAGO A.; FERNANDES,MARCOS G.; KASSAB,SAMIR O.
Estimate efficiently of the whitefly population (Bemisia tuberculata Bondar) in cassava, to assist in decision making of pest control is one of the advantages of sequential sampling plans. Therefore, the objective of this study was to determine a sequential sampling plan according to two methods of pest management, using biological and/or chemical control. Samples were obtained in a commercial field of 2.500,00 m2, divided into 100 plots. The visualization method was used for sampling of the upper leaves by counting the number of adults. In total 15 samples were taken weekly from January to April 2012. The spatial distribution model which best fit to the behavior of B. tuberculata adults was the negative binomial distribution. Levels adapted for biological...

Identification of a novel plant-derived attractant for Acromyrmex lobicornis leaf-cutting ants
Provedor de dados: 42
Autores: ALMA,ANDREA M.; FERNANDEZ,PATRICIA C.; PERRI,DAIANA; BUTELER,MICAELA.
Abstract: Leaf-cutting ants are considered major pests of agriculture and forestry in the Neotropics. Attractive toxic baits are the prevailing method for managing them. Thus, there is great interest in identifying attractants to incorporate into these baits. Moreover, leaf-cutting ants can avoid toxic baits by associating the attractant with the toxin. We evaluated attractiveness of heptyl butyrate, a volatile compound found in fresh apples and plums. We conducted field experiments with ten colonies ofAcromyrmex lobicornis. First, we evaluated the behaviour of ants exposed to heptyl butyrate at 1% by surrounding resources. Then, we compared the attractiveness of heptyl butyrate and orange pulp, the most commonly used attractant. Finally, we evaluated...

Influência de cultivar e nível de infestação de Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae) no rendimento do sorgo
Provedor de dados: 44
Autores: Cortez,Mirko G. R.; Waquil,José M.
An experiment was conducted in the greenhouse to evaluate the effect of sorghum (Sorghum bicolor) cultivars and Spodoptera frugiperda (J. E. Smith) infestations, at different plant developmental stages, on sorghum yield. Second instar larvae of S. frugiperda were used to infest plants. Significant differences (P ≤ 0,05) were found for the factors cultivar and stage of infestation for panicle (size and weight), grain (volume and weight) and 100 grain weight. No significant differences were observed for grain yield between damaged plant and the checks for the cvs. AG 3001 and CMSXS 375. However, the yield loss for the cv. BR 300 ranged from 11,6 to 21,7% for plants infested at 1st (15 days) and 4th stage (15 and 37 days), respectively.

The ectoparasite mite Varroa destructor Anderson and Trueman in southeastern Brazil apiaries: effects of the hygienic behavior of Africanized honey bees on infestation rates
Provedor de dados: 45
Autores: Pinto,F.A.; Puker,A.; Barreto,L.M.R.C.; Message,D.
In Brazil, the ectoparasitic mite of bees Varroa destructor Anderson and Trueman (Acari: Varroidae) remains at low levels of infestation causing no major damage. However, with the introduction and possible dominance of a new haplotype (K) of the mite, usually found in areas with high infestation rates (IR), it is necessary to monitor and select beehives that are resistant to the pest in order to avoid future problems. Several factors are listed as potentially being responsible for the dynamics of mite infestation, among which hygienic behavior (HB) stands out. In this context we sought to evaluate the HB of Africanized honey bees Apis mellifera L. (Hymenoptera: Apidae) compared with the mite IR in apiaries of two municipalities of southeastern Brazil...

Dispersal of Cotesia flavipes in sugarcane field and implications for parasitoid releases
Provedor de dados: 53
Autores: Dinardo-Miranda,Leila Luci; Fracasso,Juliano Vilela; Costa,Viviane Pereira da; Lopes,Diego Olympio Teixeira.
Diatraea saccharalis Fabr. (Lepidoptera: Crambidae) is a major sugarcane pest in Brazil. The management of infested areas is based on the release of Cotesia flavipes (Cameron) (Hymenoptera: Braconidae), a parasitoid of D. saccharalis larvae, but there are doubts about the effectiveness of C. flavipes, primarily regarding its rate of dispersal in sugarcane fields. Thus, the objective of this study was to evaluate the dispersal of C. flavipes in a sugarcane field and suggest a release method that provides higher parasitoid efficiency. The study was carried out in four areas of approximately 1 ha, in which stalk pieces containing 20 D. saccharalis larvae were distributed in a rectangular grid, and 12,000 C. flavipes adults were released at four points, that...

The endophytic fungus is have rich source of secondary metabolites which act as biological active agent in the higher plants. The fungal derivatives play vital part in human life and their compounds are the source of drug for cancer, microbial and viral diseases. The natural compounds from the endophytes acts as growth inhibitor of plant pathogenic organism. Endophytes are rich sources of natural products which are used in agriculture (plant growth and insecticidal), pharmaceutical industries and also used for phytoremediation.

Nymphicidal and Ovipositional Efficacy of Seaweed Sargassum tenerrimum (J. Agardh) against Dysdercus cingulatus (Fab.) (Pyrrhocoridae)
Provedor de dados: 117
Autores: Sahayaraj,Kitherian; Jeeva,Y. Mary.
We investigated the role of a brown seaweed alga, Sargassum tenerrimum (J. Agardh), against Dysdercus cingulatus (Fab.), which is an economically important cotton pest in many parts of Asia. Sargassum tenerrimum has been used as a source of fertilizers and drugs, but there is no information available in the literature about its use in ecofriendly pest management. The impact of benzene (BN), chloroform (CH), and a mixture of benzene and chloroform (BNCH) extracts, as well as two chromatographic fractions of BNCH (FR1 and FR2) were investigated for their insecticidal and ovipositional properties against D. cingulatus. The BE extract showed the best insecticidal activity (LC50 = 0.009%), higher than BNCH (LC50 = 0.021%) and CH extracts (LC50 = 0.2481%), and...
