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. 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

3. 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

4. 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

6. Agronomic performance, chromosomal stability and resistance to velvetbean caterpillar of transgenic soybean expressing cry1Ac gene.
The objective of this work was to analyze the agronomic performance and chromosomal stability of transgenic homozygous progenies of soybean [Glycine max (L.) Merrill.], and to confirm the resistance of these plants against Anticarsia gemmatalis. Eleven progenies expressing cry1Ac, hpt and gusA genes were evaluated for agronomic characteristics in relation to

7. Effect of stink bugs on yield, seed damage and agronomic traits of soybeans (Glycine max).
To evaluate the stability of the trait resistance to insects, under different dates of planting, three resistant and three susceptible genotypes were tested in an experiment set up at the experimental station of the Centro Nacional de Pesquisa de Soja (Soybean National Research Center), Embrapa, in Londrina, PR, Brazil. The study consisted of soybeans plante

8. Resistance of tomato genotypes to the greenhouse whitefly Trialeurodes vaporariorum (West.) (Hemiptera: Aleyrodidae)
The greenhouse whitefly, Trialeurodes vaporariorum Westwood, is the most common and abundant whitefly in Argentine horticultural greenhouse crops, especially in tomato (Solanum lycopersicum). Resistance in some wild tomato relatives, such as S. peruvianum, S. habrochaites and S. pennellii to the greenhouse whitefly has been described. The Mi gene confers eff

9. Effect of silicon in the induction of resistance to the spittlebug Mahanarva fimbriolata Stål (Hemiptera: Cercopidae) on sugarcane cultivars / Efeito do silício na indução de resistência à cigarrinha-das-raízes Mahanarva fimbriolata Stål (Hemiptera: Cercopidae) em cultivares de cana-de-açúcar
The present work aimed to study the effect of silicon applied in different cultivars of sugarcanes in biological and behavioral aspects of the spittlebug (Mahanarva fimbriolata) and in the yield and quality of the cane. Studies were conducted in the laboratory and on the field. In laboratory the cultivars SP79-1011 and SP80-1816 (resistant to spittlebug) and

10. Biological control of Aphis gossypii Glover (Hemiptera: Aphididae) in protected crop of cucumber using Marigold (Tagetes erecta L.) / Controle BiolÃgico do pulgÃo Aphis gossypii Glover (Hemiptera: Aphidae) em cultivo protegido de pepino com cravo-de-defunto (Tageres erecta L.)
Protected crop is a used practice in Brazil and abroad. Some characteristics like stable climate, high temperature and availability of food, favor the occurrence of pests on these systems, among them the Aphis gossypii. These insects are usually controlled chemically, which when applied in closed systems have little dispersion, thereby increasing its concent

11. Identificação e caracterização de genes induzidos por Diatraea saccharalis (Lepidoptera: Crambidae) em cana-de-açúcar / Identification and characterization of genes induced by Diatraea saccharalis (Lepidoptera: Crambidae) in sugarcane
As plantas respondem ao ataque de insetos pela indução e acumulação de um conjunto grande de proteínas de defesa. Nesse trabalho foi feita uma investigação sobre as modificações transcricionais que ocorrem em plantas de cana-de-açúcar, em resposta ao ataque de lagartas de Diatraea saccharalis. A primeira abordagem foi o estudo detalhado da induç�

12. Ciclo biológico do Rhodnius milesi (Hemiptera: Reduviidae) e a atividade de extratos de plantas
Chagas disease is transmitted to humans through feces of hemoptrous insects, subfamily Triatominae, contaminated during blood feeding. The increase in Triatominae populations resistant to available insecticides, and the appearance of new potential vector species, such as Rhodnius milesi in the Amazon region, are two pressing concerns. Given the uncharted che
