摘要
依据梨小食心虫Grapholitha molesta(Busck)的田间发生规律,在不同虫期实施不同生物防治措施,即成虫羽化期悬挂梨小食心虫性诱剂进行监测和诱杀,在产卵期释放松毛虫赤眼蜂,在幼虫孵化期使用苏云金杆菌(Bt)制剂,建立"性诱剂+松毛虫赤眼蜂+Bt"综合生物防治体系,防治效果显著。桃树平均折梢率降低为0.4%,梨树平均蛀果率降低为0.6%。
According to the occurrence regularity of G rapholitha molesta in the field,different biological control measures,ie hanging sex attractant in the adult period for monitoring and control,releasing Trichogramma dendrolimi in the oviposition period and applying Bacillus thuringiensis in the larval period,were used in different stages of the pest to establish the ＂sex pheromone ＋ Trichogramma dendrolimi ＋ Bacillus thuringiensis ＂integrated biological control system. The effect was significant. The average top-breaking rate of peach was reduced to 0. 4% and the rate of bored pear fruit was reduced to0. 6%.
