Abstract

The objective of this work was to establish a life table for the immature stages of Epinotia aporema, as part of a wider investigation on its biological control. Insects were reared on an artificial diet at 25±1ºC and a 16:8 (light:dark) hour photoperiod. For the identification of larval instars for the study of pathogen-insect interactions under laboratory conditions, head capsule widths (HCWs) were also determined. The egg incubation period was 4.13±0.30 days, larval stage took 11.64±0.49 days, and the development time of the pupal phase was sex-dependent with 8.51±0.69 days for the females and 9.41±0.65 days for the males. Five larval instars were identified.

Highlights

Biologia e morfometria dos estágios imaturos de Epinotia aporema em dieta artificial Resumo – O objetivo deste trabalho foi estabelecer uma tabela de vida para os estágios imaturos de Epinotia aporema, como parte de um estudo mais amplo para seu controle biológico
Various chemical insecticides have been used against this moth, but the interest in more environmentally friendly biopesticides such as Bacillus thuringiensis and baculoviruses has increased in the past few years (Ibarra et al 1992; Sciocco‐Cap et al 2001; Sauka et al 2007)
A recently discovered granulovirus of E. aporema (EpapGV) (Sciocco‐Cap et al 2001; Goldberg et al 2002) has been shown as a promising biological control agent when ingested by early larval instars
