DERMAL TOXICITY OF WHITE MUSCARDINE FUNGUS, Beauveria bassiana (Bals.) Vuill. ON VERTEBRATES

Pio P. Tuan

Abstract


An experiment was conducted to evaluate the dermal toxicity of Beauveria bassiana (Bals.) Vuill. on vertebrates. The effect on the treated skin of test animals was assessed 14 days post-introduction of B. bassiana conidia. Abraded skin of albino mice treated with Beauveria bassiana conidia showed no apparent clinical, pathological and histological abnormalities. The result of this test suggests that B. bassiana (GLH isolate) is a safe biocontrol agent for insect pests. It poses no harm to vertebrates including human beings.

Key Words: Conidia, substrate, microbial insecticide
