Abstract

Bio-safety of 5 Bacillus thuringiensis formulations on adult emergence in Trichogramma chilonis is reported. Maximum adult emergence (82.25 per cent) of T. chilonis adults was recorded in tricho card treated with Bt Delfin®WG (manufactured by Centris, USA, L.L.C., USA) which was at par with NBAII-BTG4 isolate (82.05 per cent), PAU Bt isolate (81.54 per cent) and PDBC-BT1 isolate (76.67 per cent) at higher dose of 20 g L−1. DiPeL8L (manufactured by Sumitomo Chemical India, Pvt. Ltd, Mumbai) recorded minimum adult emergence (70.12 per cent) at this concentration. Delfin®WG recorded minimum per cent reduction in adult emergence of T. chilonis over control(9.94 per cent). Thus, it was safe and more compatible with T. chilonis adults, and could be used as a component in integrated pest management along with trichocards.
