1. LEVANTAMENTO DA ENTOMOFAUNA EM PLANTIOS DE Eucalyptus spp. POR MEIO DE ARMADILHA LUMINOSA EM SÃO FRANCISCO DE ASSIS - RS
RESUMO A cultura do eucalipto tornou-se uma importante atividade econômica no Brasil, no entanto, com o aumento das áreas de plantio, os problemas entomológicos tendem a aumentar nas mesmas proporções. Neste sentido, torna-se necessário o constante monitoramento dos insetos associados a esses sistemas de plantios homogêneos, buscando o desenvolvimento

4. POPULATION SURVEY OF ENTOMOFAUA IN Eucalyptus spp. STANDS / LEVANTAMENTO POPULACIONAL DA ENTOMOFAUNA EM PLANTIOS DE Eucalyptus spp.
The cultivation of eucalipto has become an important economic activity in Brazil, due to its rapid growth, productive capacity, adaptability to different environments and great diversity of species, thus meeting the various sectors of industrial logging. However, with increasing areas of plantation Eucalyptus sp. entomological problems tend to increase in th

5. Biologia e tabela de vida de fertilidade de Agrotis ipsilon em dieta artificial
O objetivo deste trabalho foi desenvolver uma dieta artificial para criação de Agrotis ipsilon em laboratório com base em parâmetros biológicos e na tabela de vida de fertilidade. A dieta artificial utilizada continha feijão, caseína, proteína de soja, levedura e germe de trigo como fontes protéicas. Os parâmetros biológicos duração e viabilidad

6. Impacto dos nutrientes N e K e de açúcares solúveis sobre populações de Diabrotica speciosa (Germar) (Coleoptera, Chrysomelidae) e Agrotis ipsilon (Hüfnagel) (Lepidoptera, Noctuidae) na cultura da batata, Solanum tuberosum L. (Solanaceae)
Foi estudada a ocorrência de Diabrotica speciosa (Germar, 1824) (Coleoptera, Chrysomelidae) e de Agrotis ipsilon (Hüfnagel, 1767) (Lepidoptera, Noctuidae) em plantas de batata, cultivares Achat e Monalisa, influenciadas por dosagens de nitrogênio e potássio, e teor mínimo de açúcares solúveis. Os seguintes parâmetros foram avaliados: concentração

7. Avaliação da infestação de insetos-praga associados à batata (Solanum tuberosum L.) sob efeito de nutrientes nitrogenados e potássicos e teores acumulados de aminoácidos livres nas cultivares Achat e Monalisa
Evaluation of insect-pest infestation associated to potato (Solanum tuberosum L.) under effect of nitrogen and potassium fertilizers and the accumulated amount of free aminoacids in Achat and Monalisa cultivars. The objective of this work was to evaluate the occurence of insect-pests on potato plants influenced by dosages of nitrogen and potassium accumulate

8. Transient post-mating inhibition of behavioural and central nervous responses to sex pheromone in an insect.
Mating is costly for both male and female insects and should therefore only occur if it is likely to be successful. Within one scotophase, which is the dark period of the light cycle, male moths can only produce one single spermatophore, which is transferred to the female during mating. Remating within the same scotophase would thus be unsuccessful. We teste

9. Effect of juvenile hormone on the central nervous processing of sex pheromone in an insect
Behavioral sex pheromone responsiveness in the male moth Agrotis ipsilon was previously shown to be controlled by juvenile hormone (JH). However, this morphogenetic hormone did not change the sensitivity of antennae to sex pheromones. To analyze the possible involvement of JH in the central integration of the female-produced sex pheromone, we investigated th

10. Toxicity Analysis of N- and C-Terminus-Deleted Vegetative Insecticidal Protein from Bacillus thuringiensis
A vegetative insecticidal protein (VIP)-encoding gene from a local isolate of Bacillus thuringiensis has been cloned, sequenced, and expressed in Escherichia coli. The expressed protein shows insecticidal activity against several lepidopteran pests but is ineffective against Agrotis ipsilon. Comparison of the amino acid sequence with those of reported VIPs r

11. Auditory sensitivity of Hawaiian moths (Lepidoptera: Noctuidae) and selective predation by the Hawaiian hoary bat (Chiroptera: Lasiurus cinereus semotus).
The islands of Hawai'i offer a unique opportunity for studying the auditory ecology of moths and bats since this habitat has a single species of bat, the Hawaiian hoary bat (Lasiurus cinereus semotus), which exerts the entire predatory selection pressure on the ears of sympatric moths. I compared the moth wings discarded by foraging bats with the number of s

12. Role of Bacillus thuringiensis Cry1 δ Endotoxin Binding in Determining Potency during Lepidopteran Larval Development
Five economically important crop pests, Manduca sexta, Pieris brassicae, Mamestra brassicae, Spodoptera exigua, and Agrotis ipsilon, were tested at two stages of larval development for susceptibility to Bacillus thuringiensis toxins Cry1Ac, Cry1Ca, Cry1J, and Cry1Ba. Bioassay results for M. sexta showed that resistance to all four Cry toxins increased from t
