Studies on the life history and life stages of the black cowpea moth, Cydia ptychora
Published online by Cambridge University Press: 19 September 2011
Abstract
1. Under laboratory conditions (25 to 27°C), female Cydia ptychora (Meyrick) laid an average of 44 eggs. 2. The egg incubation period was 5 days, while the larval developmental period lasted 7 to 10 days, and the pupal period 12 days. Thus, the total developmental period (egg to adult) lasted 24 to 27 days. The adult longevity averaged 10 days (13 to 15 days). 3. Descriptions of the different life stages and setal maps of the different larval instars are provided.
