     Aims to develop effective, safe and environmental friendly bio-insecticides for controlling root insects, vegetable insects and other important insects through screening, fermentation technology, formulation, and application techniques for highly insecticidal strains of potentially useful microbes.

  • Research Progress

    Several Beauveria bassiana strains with high toxicity to diamond back moth Plutella xylostella, tobacco whitefly Bemisia tabaci, scarabaeoidea Holotrichia oblita and elm leaf beetle Pyrrhalta aenescens has collected. An oil suspension formulation of B. bassiana had developed for controlling diamond back moth and tobacco whitefly of vegetable pest. Many Bacillus thuringiensis strains to control soil habit pests Bradysia odoriphaga, Holotrichia oblita and Anomala corpulenta had obtained.  Their cry gene from those Bt strains had cloned. Their fermentation technology, formulation, application techniques for target pest had developed.
