温棚油桃梨小食心虫消长规律及不同诱捕器诱杀试验

Study on Population Fluctuations of Grapholitha molesta Busck and the Trap Efficiency of Different Traps in Greenhouses

【目的】为不同诱捕器在温棚油桃防治梨小食心虫提供依据。【方法】利用梨小食心虫性诱剂对新疆喀什地区叶城县温棚油桃梨小食心虫进行不同诱捕器(三角型粘胶式诱捕器、矿泉水瓶诱捕器、塑料桶诱捕器)诱捕效果的比较。【结果】温棚油桃梨小食心虫1年发生4代,分别出现在4月中旬、6月上中旬、7月上旬、8月上中旬。【结论】在三种诱捕器中,自制的矿泉水瓶诱捕器最佳,其次为三角型粘胶式诱捕器,塑料桶诱捕器较差,为诱捕器的研制工作提供科学依据。

[Objective]The purpose of this program was to provide the basis for using different traps on Grapholitha molesta Busck in greenhouses.[Method]Comparison of different traps（triangle box sticky trap, plastic water bottle trap,plastic drum trap） trapping Grapholitha molesta Busck in greenhouses was made. [Result]Four generations of Grapholitha molesta Busck occurred in one year in greenhouses.They generally appeared in the mid - April,early June - mid - June,early July and early - mid - August.In the three traps, plastic water bottle trap had the most efficient result,followed by triangle box sticky trap.Plastic drum trap was the worst.[Conclusion]The results provided the scientific basis for the trap development.
