1. 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

2. Preferences and demographic parameters of cowpea aphid on advanced lines of semiprostrate cowpea
Resumo: O objetivo deste trabalho foi determinar a preferência e os parâmetros demográficos do pulgão-preto (Aphis craccivora), em linhagens avançadas de feijão-caupi (Vigna unguiculata) de porte semiprostrado, e verificar a existência e o tipo de resistência da planta ao ataque do inseto. Avaliou-se a preferência do inseto a 20 genótipos de feijã

3. 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

4. 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

5. 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

6. Biological aspects of the beetle Delphastus davidsoni fed with whitefly eggs laid on tomato genotypes
Many plant breeding programs have incorporated plant resistance characteristics without considering how this resistance may affect the natural enemies of plant pests. We evaluated the biological aspects of Delphastus davidsoni (Gordon) fed with Bemisia tabaci B biotype eggs laid on tomato genotypes with different trichome densities and types. On LA1335 and N

7. 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

8. Structure of genetic diversity of Bemisia tabaci (Genn.) (Hemiptera: Aleyrodidae) populations in Brazilian crops and locations
Bemisia tabaci (Genn.) represents a complex of cryptic species that causes losses of many valuable crops. Even though there are differences in their ability to colonize hosts, transmit phytovirus and develop resistance to insecticides, the genetic differentiation of the insect populations is important for the adoption of control measures. Therefore, the gene

9. 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

10. Fotossíntese, crescimento e composição química em plantas de Theobroma cacao L. submetidas a diferentes concentrações de silicato de potássio e sua interação com insetos-praga / Photosynthesis, growth and chemical composition in plants of Theobroma cacao L. subjected to different concentrations of potassium silicate and its interaction with insect-pests
The control of insect pests through the use of pesticides, is still the most method used in the cultivation of cocoa. However, due to environmental issues, there need to seek new alternatives of control less harmful the environment and to humans. In this context, silicon is a nutrient that is being used in various cultures, due to its beneficial effects on p

11. Silicon influence on resistance induction against Bemisia tabaci biotype B (Genn.) (Hemiptera: Aleyrodidae) and on vegetative development in two soybean cultivars
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

12. Induction of insect plant resistance to the spittlebug Mahanarva fimbriolata Stål (Hemiptera: Cercopidae) in sugarcane by silicon application
Changes in the agroecosystem with the increase of green cane harvesting in Brazil affected the insect populations associated to this crop, and secondary pests like the spittlebug Mahanarva fimbriolata Stål, became much more important. Many studies have demonstrated the active role played by silicon in plant defense against herbivory. The objective of this s
