Abstract

Beauveria bassiana (Bals.) was bio-assayed against three larval instars of Atteva sciodoxa under laboratory conditions of 27±2ºC, 75% RH and 12:12 H photoperiod. Instar 3rd responded with 100% mortality at 5x107 conidia ml-1, while same level of mortality was recorded in 5th instar at 1x108 conidia ml-1. Instar 5 also showed the lowest mortality (33.3%) at 1x106 conidia ml-1. Median effective concentration (EC50) ranged between 9.87x105 and 21.30x105 conidia ml-1 for 3rd to 5th instars. Median effective time (ET50) ranged between 3.3 days and 8.2 days for different tested concentrations. A significant (p
