A low-cost trap for Cerambycidae monitoring in forest plantations in Brazil PAB
Fernandes,Flávio Lemes; Picanço,Marcelo Coutinho; Chediak,Mateus; Fernandes,Maria Elisa Sena; Ramos,Rodrigo Soares; Moreira,Suzana de Sá.
The objective of this work was to evaluate the use of a low-cost trap to capture Cerambycidae in different seasons in planted forests in Brazil. Thirty polyethylene-terephthalate trap bottles per hectare were used, disposed at every 50 m. The traps were red painted and contained glass flasks with a mixture of ethanol, methanol and benzaldehyde. There were soap and water at the trap bottom. The traps were checked biweekly for beetle presence. Sampling time required one minute per sample, and traps were easy to use. Total sampling cost, including materials and labor, was US$ 13.46 per sample. Six Cerambycidae species were captured along the dry and rainy seasons.

A review of geminivirus diseases in vegetables and other crops in Brazil: current status and approaches for management Horticultura Brasileira
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...

Antioxidant activity of methanolic extracts from Cydonia oblong leaves IPB - Escola Superior Agrária
Bento, Albino; Pereira, J.A..
The olive moth, Prays oleae (Bernard) (Lepidoptera: Yponomeutidae), is one of the most destructive pests of olive groves in the Mediterranean basin. In recent years, the interest in evaluating the economic importance of P. oleae has been increasing, being loss assessment essential to the development of integrated pest management programs (IPM). Reliable economic thresholds for the pest are associated to any IPM practice, since enables the growers to reduce the input of pesticides and even target their use, when necessary. The purpose of this study was to establish economic thresholds against the fruit generation of P. oleae (Bern.) in Trás-os-Montes region (north-eastern Portugal), where the olive moth is a key pest of olive (Bento et al., 1997; Bento,...

Fernandes,Maria Herlândia de Araújo; Menezes,Karen Oliveira de; Souza,Adriana Maria de; Almeida,Jackson Roberto Guedes da Silva; Oliveira,José Eudes de Morais; Gervásio,Rita de Cássia Rodrigues Gonçalves.
Abstract: The objective of this work was to evaluate the lethal and sublethal toxicity of hexane and methanolic extracts from the leaves of Annona vepretorum (Annonaceae) on Tetranychus urticae (Acari: Tetranychidae). The methanolic extract toxicity was evaluated by Potter tower application (topical + residual effect) and by immersion of Canavalia ensiformis leaf disks in the extract solution (residual contact effect). The hexane extract toxicity was evaluated exclusively through residual contact effect. Sublethal effects of the methanolic extract were evaluated through LC50 on the females. Mite preference for feeding and oviposition was evaluated by multiple choice tests, between the control and the extract concentrations, using the hexane and methanolic...

Biological Control in Brazil: an overview Scientia Agricola
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....

Bueno,Regiane Cristina Oliveira de Freitas; Carneiro,Tatiana Rodrigues; Pratissoli,Dirceu; Bueno,Adeney de Freitas; Fernandes,Odair Aparecido.
This research aimed at studing Telenomus remus Nixon biology reared on Spodoptera frugiperda (J.E. Smith) eggs at different temperatures. Based on the development of the cycle (egg-adult), the thermal requirements and the number of parasitoid generations at constant temperatures were determined. Initially, 24-hour-old S. frugiperda eggs were submitted to parasitism by T. remus during 5 h, being then transferred to acclimatized chambers regulated at 15, 20, 25, 28, 31, and 35°C. The cycle (egg to adult) was influenced by temperature varying from 8.3±0.01 to 47.2±0.01 for females and 8.1±0.01 to 46.8±0.01 days for males at 31 and 15°C, respectively. The emergency (%) was also influenced by temperature. A reduction in emergency was observed at 15°C and no...

Common bean resistance expression to whitefly in winter and rainy seasons in Brazil Scientia Agricola
Silva,Anderson Gonçalves da; Boiça Junior,Arlindo Leal; Farias,Paulo Roberto da Silva; Souza,Bruno Henrique Sardinha de; Rodrigues,Nara Elisa Lobato; Carbonell,Sérgio Augusto Morais.
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,...

Do Pesticide Hazards to Human Health and Beneficial Insects Cause or Result from IPM Adoption? Mixed Messages from Farmer Field Schools in Nicaragua AgEcon
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...

Does Bt maize cultivation affect the non-target insect community in the agro ecosystem? Rev. Bras. entomol.
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.

Does It Matter Who Scouts? AgEcon
Lichtenberg, Erik; Berlind, Ayesha Velderman.
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...

Ecological modeling and pest population management: a possible and necessary connection in a changing world Neotropical Entomology
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...

ECONOMIC ANALYSIS OF ENVIRONMENTAL BENEFITS OF INTEGRATED PEST MANAGEMENT AgEcon
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.
