梨小食心虫Grapholitha molesta(Busck)是重要的蛀果类害虫之一,目前性信息素广泛应用于梨小食心虫防治,为明确性信息素陷阱诱捕器的诱捕效果,针对开口方式设计四面开口和两面开口两种处理的陷阱诱捕器;针对口径的大小下设计2、3、4、5、6 cm的5种口径的对口瓶陷阱式诱捕器,分别在桃园对梨小食心虫进行诱捕试验,诱捕结果显示两面开口的诱捕器诱捕效果比四面开口的诱捕器效果显著,口径为2 cm和3 cm的陷井式诱捕器诱捕效果最佳,诱捕量显著高于5 cm和6 cm,诱捕量达34.6头/日和20.4头/日。通过试验明确了陷阱诱捕器的最佳诱捕效果的参数,同时为测报及田间大量诱杀的诱捕器使用提供依据,为防控梨小食心虫性信息素诱捕器提供标准化参数。
Grapholitha molesta (Busck) is one of the important pests of fruit borer. At present, the sex pheromone is widely used in the control of pest insects, and in order to clarify the trapping effect of the sex pheromone trap traps, four openings and two sides Opening traps trap trap; for the size of the size of the design 2,3,4,5,6 cm of the five caliber counterpart trap traps traps Pear Moth in Pear trap experiment, trapping results Trapping traps with two open sides showed better trapping effect than traps with four open traps. Trap traps with caliber of 2 cm and 3 cm had the best trapping effect, trapping amount significantly higher than 5 cm and 6 cm, and trapping amount was 34.6 Head / day and 20.4 head / day. Through experiments, the parameters of trap traps’ best trapping effect were determined. At the same time, the parameters of trap traps used for measuring traps and field traps were provided, which provided the standard parameters for preventing and controlling pest pheromone pheromone traps.
