BIOTOXICITY ANALYSIS OF DIFFERENT DOSES OF BEAUVERIA BASSIANA (BALSAMO) VUILLEMIN AGAINST NYMPH OF ODONTOTERMES OBESUS (R.)Anjana Intodia, Arti Prasad and Bharati Veerwal
Termites are soil-dwellers and carry out various activities in hidden-quarters without being detected. They pose a serious threat to agricultural, horticultural crops, forestry trees, and wooden structures. Use of entomopathogenic fungus can be a ecofriendly approach as comparable to chemical insecticides for control of various castes of termites. Entomopathogenic fungi are important natural enemies of arthropods and can be used as biological control agents. Bio efficacy of different concentrations of entomopathogenic fungus Beauveria bassiana (Balsamo) Vuillemin were evaluated against nymphs of termite Odontotermes obesus (R.) in laboratory conditions. The treatment results clearly revealed that the rate of mortality was increased with concentration and exposure period of treated dose of Beauveria bassiana on nymph of termite.
