Abstract

The development time of the larval stages of Brassolis sophorae (Linnaeus, 1758) was determined, as well as some aspects of their behavior, using Roystonea oleracea (Jacq.) O. F. Cook as food, under laboratory conditions. This species is considered a pest in Araceae plantations. The average incubation time of the eggs was 27.67 days and their viability varied between 97.64% and 84.74%. The total development of the larval stage passes through seven instars in an average time of 120.61 days. When the larvae reach the seventh instar, they leave the nest or shelter and look for a safe and dry environment, this is done solitarily, and larval aggregation is no longer observed. The prepupa lasts an average of 3.15 days and is characterized by the cessation of feeding and movement. The average duration of female pupae was 15 days and for males, the duration was 14.44 days. The average longevity under laboratory conditions for the adult stage was 9.66 days. Males were found to start their rapid and irregular flight activity earlier than females, at 5:30 p.m. and females at 6:00 p.m. but females remained active longer than males.
