Abstract:
Investigations were carried out to assess the biotic potential by T. chilonis on eggs of Corcyra cephalonica by applying different insecticides chlorantraniliprole 18.5 SC, profenofos 50 EC, cartap hydrochloride 50 SP, spiromesifen 22.9 SC, buprofezin 25 SC, flubendiamide 20% WG, azadirachtin 1500 ppm and lambda cyhalothrin 9.5% + thiamethoxam 12.6% ZC on host egg. The bioassay studies under laboratory conditions were carried out to determine the insecticides effect on parasitization by T. chilonis on insecticide treated factitious host eggs of Corcyra cephalonica Stainton. For the experiments biotic potential, un-irradiated eggs of host insect i.e. Corcyra cephalonica were used. The results on biotic potential studies revealed that the maximum percent parasitization of Trichogramma chilonis was obtained in the treatment of azadirachtin 1500 ppm whereas lowest in the treatment of cartap hydrochloride 50 SP. The other relatively harmless insecticides were chlorantraniliprole 18.5 SC and flubendiamide 20% WG in which > 50 percent parasitization was obtained and categorized as harmless and slightly harmful respectively.
