Abstract:

Laboratory experiment was conducted to evaluate the efficacy of two important anthocorid predators, Blaptostethus pallescens Poppius and Xylocoris flavipes (Reuter) for the suppression of stored grain pest of rice, Corcyra cephalonica Stainton. Performance of both the anthocorid bug is significant against the infestation of C. cephalonica in storage. However, due to smaller size of X. flavipes, it was better than B. pallescens to enabling them to fit in storage condition. The higher doses of X. flavipes @ 30 nymphs/100 eggs/ jar (12.75-18.00 moths/jar) and 20 nymphs/ 100 eggs/ jar (26.50- 26.75 moths/ jar) were found to be most effective in suppressing the population build-up of C. cephalonica in stored rice grain. X. flavipes with respect to nymphal survival was found to be most suitable as higher number of their living nymphs (4.50-14.25 nymphs/ jar) was recovered as compared to B. pallescens, where, negligible number of living nymphs (0- 7.70 nymphs/ jar) was recovered. It was concluded that X. flavipes @ 30 nymphs/ jar, followed by X. flavipes @ 20 nymphs/ jar was most effective in controlling C. cephalonica in storage of rice grain.
