Eclosion time and larval behavior of the tomato fruit borer, Neoleucinodes elegantalis (Guenée) (Lepidoptera: Crambidae)

Abstract: 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… Show more

“…Adults are active at night only. First‐instar larvae have low mobility and bore inside the fruits within a few minutes of hatching (Eiras & Blackmer, 2003). When the fruits are unavailable, larvae are moribund (W. Pontes, unpublished data).…”

“…The neonate larvae penetrate the fruit quickly, thus protecting themselves from insecticides (Eiras and Blackmer, 2003). Hence, the results obtained in this study will bring new perspectives to the management of N. elegantalis in tomato crops in the Agreste region of Pernambuco, by using etofenprox, fenpropathrin and methomyl as ovicidal agents, chlorpyrifos and lambda-cyhalothrin as oviposition deterrents, and lufenuron and deltamethrin in toxic baits.…”

“…A influência positiva do óleo vegetal pode estar associada à maior permeabilidade do córion do ovo ao inseticida, impedindo o completo desenvolvimento embrionário, pois, segundo Muñoz et al (1991), ocorre perda de turgescência do córion ao longo do período de incubação, o que resulta em maior resistência à absorção do agrotóxico. A adição de óleo vegetal à calda inseticida com o objetivo de reduzir a tensão superficial da gota para promover maior cobertura dos frutos também foi citada por Eiras; Blackmer (2003), pois, devido à alta cerosidade da superfície do fruto, o adjuvante promove cobertura mais uniforme (Paula et al, 1998).…”

“…Os orifícios de entrada das lagartas recém-eclodidas nos frutos são observados com maior frequência na porção mediana-inferior, indicando que o volume de calda aplicado até atingir o ponto de escorrimento ou a adição de adjuvantes resultaria em cobertura mais homogênea e, consequentemente, maior proteção à infestação por lagartas (Eiras; Blackmer, 2003). A informação quanto à preferên-cia de entrada no fruto passa a ser estratégica para o sucesso do manejo da praga, pois permite que o produtor também faça o controle químico com o jato da calda inseticida direcionada para os frutos em fase inicial de desenvolvimento, visando impedir a entrada das lagartas recém-eclodidas.…”
