1. Effectiveness of coffee leaf miner control associated with spray deposition in coffee leaves
ABSTRACT Coffee production faces challenges due to the susceptibility of the crop to insects. Owing to the coffee leaf miner Leucoptera coffeella, which is one of the main insect pests, the technology for the application of phytosanitary measures becomes the main challenge for coffee growers. This study aimed to evaluate the effectiveness of coffee leaf mine

2. Effect of canopy cover on development of cedar (Cedrela fissilis) and aspects of damage caused by Hypsipyla grandella in agroforestry system
Resumo Cedrela fissilis (Vell.) é uma importante espécie madeirável nativa da América do Sul que sofre frequente pressão do extrativismo ilegal. As iniciativas de cultivo comercial acumulam fracassos recorrentes pela ação da broca-do-cedro Hypsipyla grandella (Zeller, 1848). Um dos métodos de manejo utilizados para reduzir os ataques é o plantio em

3. Silicon as resistance inducer in to control black aphid Aphis craccivora Koch, 1854 in Phaseolus lunatus lima beans
RESUMO São poucos os registros no Brasil de insetos associados à cultura da fava; entre eles, destaca-se o pulgão preto Aphis craccivora Koch, 1854. O objetivo deste estudo foi avaliar os efeitos da aplicação de silício na indução de resistência de plantas de feijão-fava Phaseolus lunatus a esse inseto. O experimento foi conduzido no Laboratório d

4. Development of Oryzophagus oryzae (Costa Lima) in rice cultivars
RESUMO Cultivares resistentes a insetos são essenciais à melhoria do manejo de pragas como Oryzophagus oryzae (Coleoptera: Curculionidae), altamente prejudicial à cultura do arroz irrigado por inundação. O grau de benefício, porém, depende do tipo de resistência. Objetivou-se avaliar cultivares de arroz quanto à resistência a O. oryzae, inferindo

5. Common bean resistance expression to whitefly in winter and rainy seasons in Brazil
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

6. Protease inhibitory, insecticidal and deterrent effects of the trypsin-inhibitor benzamidine on the velvetbean caterpillar in soybean
Abstract The recognition of protease inhibitors with insecticidal activity is important as a basis for the development of mimetic peptides with potential use as biorational insecticides. We sprayed benzamidine on soybean plants and assessed whether this potent synthetic trypsin-inhibitor has protease inhibitory, insecticidal and deterrent effects on the velv

7. Resistance to Dichelops melacanthus (Hemiptera: Pentatomidae) in soybean genotypes of different maturity groups
ABSTRACT Some species of pentatomids stink bugs have global economic importance, damaging various plant species during the vegetative and reproductive phases. Dichelops melacanthus (Dallas) (Hemiptera: Pentatomidae), known as the green-belly stink bug, is part of the soybean stink bug complex in Brazil and has increasing importance in crops,with potential to

8. A Química na agricultura: perspectivas para o desenvolvimento de tecnologias sustentáveis
Food production and preservation of the environment are among the challenges faced by contemporary society. In Brazil, as in most parts of the world, the possibility of increasing the agricultural area is limited by several factors. Thus, an increase in productivity through the application of innovative technologies is regarded as the best solution to overco

9. First record of damage by an insect pest in a commercial amaranth crop in Brazil
Insect pests have not been recorded for amaranth (Amaranthus cruentus L.) in Brazil. Generalized plant lodging was observed after the grain-filling period in an irrigated commercial amaranth crop (7 ha), located in Cristalina, state of Goiás (Brazil), which was cultivated between Aug. and Dec. 2009. Almost all sampled plants presented internal galleries bor

10. Fatores de mortalidade natural da cochonilha-farinhenta Planococcus citri no cafeeiro / Natural mortality factors of mealy-mealybug Planococcus citri in coffee
Understanding the factors that regulate populations of insect pests is of fundamental importance in the development of programs for integrated pest management. Scale insects, especially Pseudococcidae family, have reached the "status" in many pests in crops such as coffee plant. In one group of pests is the most important species Planococcus citri (Risso) (H

11. Biologia e comportamento de Sitobion avenae (Hemiptera: Aphididae) em quatro cultivares comerciais de trigo (Triticum aestivum L.) / Biology and behavior of Sitobion avenae (Hemiptera: Aphididae) in four commercial varieties of wheat
The use of resistant wheat cultivars to S. avenae is important for the management of culture due to the potential damage of aphid. In Brazil, however, little is known about the resistance of wheat cultivars to S. avenae. The goal of this work was to assess the behaviour and biology of S. avenae in leaves and ears of four commercial wheat cultivars to verify

12. DANOS DO PERCEVEJO-BARRIGA-VERDE Dichelops melacanthus (DALLAS, 1851) (HEMIPTERA: PENTATOMIDAE) NA CULTURA DO MILHO / GREEN BELLY STINK BUG Dichelops melacanthus (DALLAS, 1851) (HEMIPTERA: PENTATOMIDAE) DAMAGES IN MAIZE CROP
The research objective was to evaluate the damage caused by D. melacanthus in the initial phase of the maize crop. Two field trials were conducted in Rondonópolis, Mato Grosso, and two greenhouse trials occurred in Santa Maria, Rio Grande do Sul. In all experiments artificial infestation of cages was done using laboratory reared stink bugs. In all experimen
