Última Avaliação do feromônio sexual de Neoleucinodes elegantalis Guenée (Lepidoptera: Crambidae) Neotropical Entomology Badji,Cesar A.; Eiras,Alvaro E.; Cabrera,Aivlé; Jaffe,Klaus. Foram avaliados os quatro componentes sintéticos identificados no feromônio sexual da broca-pequena-do-tomate, Neoleucinodes elegantalis Guenée (BPT): (E)-11-hexadecenol (E11-16:OH), (Z)-11-hexadecenol (Z11-16:OH), (E)-11-hexadecenal (E11-16:Al) e (E)-11-Acetato de hexadecenila (E11-16:OAc). Testes de campo foram realizados com armadilhas objetivando identificar o composto mais eficaz na captura de machos do inseto e determinar o efeito de concentrações do isômero Z11-16:OH, em mistura com o componente mais eficaz na captura de machos. Em laboratório, foram realizados testes eletrofisiológicos com eletroantenógrafo para monitorar as respostas da antena de machos de N. elegantalis a diferentes concentrações dos componentes. E11-16:OH, na concentração de 100... Tipo: Info:eu-repo/semantics/article Palavras-chave: Insecta; Armadilha; Broca-pequena-do-tomate; EAG; Monitoramento.

M. de. Neoleucinodes elegantalis (Guenée) is one of the most important pests in several tomato growing regions of Brazil. The neonate larva enters the fruit shortly after eclosion, a characteristic that limits the effectiveness of insecticides and biological control agents. A better understanding of the cues that elicit or inhibit host-plant location and oviposition by N. elegantalis could lead to novel control strategies. Our findings indicate that N. elegantalis deposited 89% of its eggs on small fruits (23.1±0.95 mm), and that 76% of the eggs were placed on the first four basal fruits within the fruit cluster. The average number of eggs/egg mass was 2.9±0.17 (range 1-13), and approximately 70% of these were deposited in a single oviposition bout. The...

Ano: 2001 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S1519-566X2001000100014 Eclosion time and larval behavior of the tomato fruit borer, Neoleucinodes elegantalis (Guenée) (Lepidoptera: Crambidae) Scientia Agricola Eiras,Alvaro E.; Blackmer,Jacquelyn L.. In several regions of Brazil, Neoleucinodes elegantalis (Guenée) is one of the most serious tomato pests. The moth lays eggs on the calyx or developing fruit, and shortly after eclosion larvae penetrate into the fruit, where they remain until pupation. Once larvae have entered the fruits, insecticides and biological control agents are relatively ineffective. Because N. elegantalis is most susceptible to conventional treatments when the larvae are outside the host tissues (or fruit), it would be advantageous to know the time required for egg development and the length of time that the larvae spend on the surface of the fruit. To answer these questions detailed behavioral studies were untaken. Eggs were collected from the field and maintained in an...
