Pathogenicity of Oryctes Baculovirus to Cashew Stem and Root Borers

Plocaederus ferrugineus L., P. obesus Gah and Batocera rufomaculata DE G are the stem and ischolar_main boring pests of cashew. Among them, P. ferrugineus is the most dominant species. Rajapakse aud Jeevaratnam (1982) reported that P. ferrugineus infestation could be effectively checked with Oryctes baculovirus in Sri Lanka. An attempt was made to study the efficacy of Oryctes baculovirus (OBV) in the control of P. ferrugineus and P. obesus in the field and laboratory conditions and the results are reported in this short paper.
