The parasitism potential and low temperature storage response of Trichogramma kashmirica Nagaraja, Ahmad and Gupta was studied at 27+1°C and 6% per cent RH. The females on average parasitized 81.0±20.0 eggs of Corcyra cephalonica during their life span of 7.01k1.99 days. The per cent emergence and females declined from 96.0 to 60.6 and 88.3 to 86.8, respectively, after storage for 45 days at 6°C. Adult emergence and longevity of females were negatively correlated, whereas developmental period was positively correlated with storage period.

Abstract


The parasitism potential and low temperature storage response of Trichogramma kashmirica Nagaraja, Ahmad and Gupta was studied at 27+1°C and 6% per cent RH. The females on average parasitized 81.0±20.0 eggs of Corcyra cephalonica during their life span of 7.01k1.99 days. The per cent emergence and females declined from 96.0 to 60.6 and 88.3 to 86.8, respectively, after storage for 45 days at 6°C. Adult emergence and longevity of females were negatively correlated, whereas developmental period was positively correlated with storage period.
