文档介绍：不同性诱芯防治梨小食心虫效果比较
摘要:2009年在山西省太谷县西山底桃园用3种性信息素对梨小食心虫进行了诱捕迷向防治试验。结果表明,澳大利亚迷向丝对梨小食心虫有很好的迷向效果,动物所性信息素诱芯对梨小食心虫有很好的诱捕效果,且方法简单,无公害。迷向丝处理6天后,迷向丝对梨小食心虫的迷向率高达100%,动物所性诱芯在20日-23日每日平均诱捕量达到90头,在梨小食心虫发生高峰期过后任然能平均每日诱捕10头,诱捕效果良好。由此可见,迷向丝和动物所性诱芯可推广应用于梨小食心虫的防治工作中。

Abstract :Taigu in Shanxi Province in 2009 at the end of Taoyuan County, the Western Hills with three kinds of sex pheromone of the pear borer a small fan to the control of trapping. The results showed that the Australian fans to the wire molesta on pears have a good fan to the effect, animal sex pheromone by inducing a small core of the pear borer trapping a very good effect, and the method is simple, non-pollution. Fans to the wire for 6 days, fans of the pear to the wire of the fan molesta to as high as 100% of animals induced by the core on the 20th in a daily average of -23 on trapping capacity of 90, took place in the pear peak molesta However, after the term of office to a daily average of 10 traps, trapping well. It can be seen, and animal lovers to the wire induced by the core of pears can be used to promote the prevention and treatment molesta work.

前言
据联合国粮农组织调查资料介绍,全球每年被病虫害夺去的果物占收成的20%—30%,由此造成的经济损失达1200亿美元。世界各国为了对付日益复杂的病虫害,目前农业生产上害虫防治的主要手段还是依赖于化学农药,每年要生产各种化学农药200多万吨,但长期无节制的使用化学农药带来许多副作用。一是害虫抗药性的产生,致使用药量和用药浓度不断增加,成本逐年增加,防治日益困难;二是破坏生态平衡,在控制害虫的同时,大量天敌被杀伤,造成次要害虫猖獗;三是污染环境,化学农药相当一部分是高毒高残留,容易残留在植物表面以及土壤中,不容易降解,会随着雨水等流入江河毒死鱼类,还可以在鱼等动物体内蓄积,人食用后容易产生慢性中毒,甚至致癌等。在这种情
