影响桃小食心虫性诱剂田间诱捕效率的几种因子的研究

Factors Influencing on Trapping Efficiency of Sex Pheromone for Carposina sasakii in Fields

考察影响桃小食心虫Carposina sasakii诱捕器诱捕效率的几种因子,结果表明,中捷四方性诱剂诱捕效率显著高于另一型号。3种诱捕器在诱捕效率上存在明显差异,船型诱捕器具有较高的监测效率。诱捕器诱捕半径以20～25m为最佳诱捕范围,与15m和30m的差异显著。地面植被覆盖程度对诱捕器诱捕效率有明显影响,且诱捕器在林冠层相对开放、同时无低矮灌木层条件下,易于发挥其诱捕作用。

Several factors influencing the trapping efficiency of the traps on Carposina sasakii were investigated.The sex pheromone from the Zhongjiesifang company trapped more moths than another product.Trap design affected trapping efficiency,the Wing trap was more efficient.The effective trapping radius was 2025 m,trap catches were significantly higher at that distance than at 15 m or 30 m.And trapping efficiency was also connected with vegetation coverage,trap catches were higher in areas of open forest canopy without low shrub.
