Abstract:
From 2022 to 2023, a study under laboratory conditions was conducted at BTCCARS in Bilaspur to determine the life cycle of the diamondback moth Plutellae xylostella (Lepidoptera: Plutellidae) under laboratory conditions. As a result, the egg period was 2.90±0.26 days, the larval period was 10.55±0.47 days, the prepupal period was 1.5±0.11 days, and the pupal period was 4.80±0.17 days. Total lifespan under laboratory conditions varied between 17 and 28 days, averaging 21.35±0.82 days. The study also found that larval instars differed in length, with the 1st instar being the shortest and the 4th instar being the longest. The length of the pupal period also varies, with some pupae hatching in 4 days and others in 6 days. The results of this study provide valuable information on the diamondback moth life cycle that can be used to develop more effective pest management strategies.
