几种因素对梨小食心虫性诱剂诱捕量的影响

采用田间诱集效果试验,就诱捕器不同置放高度、不同置放方位、不同诱芯剂量、不同类型诱捕器对梨小食心虫的诱集数量进行了研究,以探讨梨小食心虫性诱剂应用的关键技术。结果表明:悬挂高度越高诱捕效果越好,桃树的西方诱捕效果最好;诱剂量以6个诱芯的诱捕效果最好,平均为38.75头/诱捕器,其次为2个诱芯,诱捕效果为31.00头/诱捕器;几种诱捕器对梨小食心虫都有一定的诱捕效果,其中三角诱捕器诱捕效果最好,其次为自制水瓶诱捕器,诱捕效果分别为138.75头/诱捕器和100.25头/诱捕器。

Effects of Several Factors on Trapped Quantity of Grapholitha molesta with Sex Pheromone

The key application technology for sex pheromone of Grapholitha molesta Busck was studied in hanging height and orienation,doses and types of traps through the test on trapping quantity in field.The results showed that the trapping efficiency was enhanced when the hanging height increased and the trapping effect was the best in the west.The trap efficiency was enhanced when the dosage was increased.When it was up to 6 lure,the trapping effect was the best with 38.75 individuals each trapper;the next was 2 lure with 31.00 individuals each trapper.All the tested types of trapper had trapping ability to Grapholitha molesta,among which,triangle trapper was the best followed by homemade bottle trapper.Their trapping efficiency were 138.75 and 100.25 individuals each trapper respectively.
