Resumen
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. Os insetos foram criados em dieta artificial a 25±1ºC e 16:8 (luz:escuridão) horas de fotoperíodo. Para a identificação dos estágios larvais para estudos de interação inseto‑patógeno em condições de laboratório, as larguras de cápsula cefálica também foram determinadas. O período de incubação dos ovos foi de 4,13±0,30 dias, o estágio larval foi de 11,64±0,49 dias, e o tempo de desenvolvimento das pupas dependeu do sexo, com 8,51±0,69 dias para as fêmeas e 9,41±0,65 dias para os machos. Foram identificados cinco estágios larvais.
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.
