Abstract

Pulse crops are faced with a major biotic constraint globally, and they are attacked by Helicoverpa armigera (Hübner) (Noctuidae), also known as the pod borer, across various regions including Asia, Europe, Africa, Australia, and South America. It is widely recognized as a key agricultural pest. Study of their life cycle revealed that total larval period were recorded (20.00±3.21) days from 1^st instar to 6^th instar under laboratory conditions at 26°C with 65 % relative humidity revealed. The mean duration was (2.66±0.33), (2.66± 0.33), (2.33± 0.33), (3.66± 0.88), (4.33± 0.66), and (4.33±0.88) days of 1^st , 2^nd , 3^rd, 4^th ,5^th and 6^th larval instar respectively during April-May 2022.The average incubation period of egg ranged from(4.66±0.88) days. The pod borer passes through six larval instars to become an adult.
