Johnson Wahengbam, AM Raut, SK Mandal and A Najitha Banu

The experiment was conducted at Bio-control Laboratory, Department of Agricultural Entomology, Bidhan Chandra Krishi Viswavidyalaya, Mohanpur, West Bengal during 2014 to investigate the toxic effect of modern insecticides (Spiromesifen, Rynaxypyr, Cyazypyr, Thiacloprid and Tolfenpyrad) on pupal stage of hymenopteran parasitoids. The trial was arranged in Factorial Complete Randomised Design consist of ten treatments excluding control with three replication. The present experiment resulted that the 100 per cent mortality was obtained in application of Tolfenpyrad 15% EC @ on Trichogramma chilonis Ishii and T. pertiosum Riley. All new molecules, spiromesifen, rynaxypyr, cyaxypyr and thaicloprid were observed harmless towards trichogramma species and use as a IPM component. The interaction between insecticidal treatment and parasitoids species was non-significant. The first report of new formulation of rynaxypyr 35 WG was observed harmless effect on T. chilonis and T. petiosum
