| 摘 要： | 性诱技术是应用于果园的一种无公害、绿色防治技术。梨小食心虫是江西省梨产区的一种主要害虫,为了寻求适时有效的防治方法,于2012年,利用性诱剂迷向散发器(即迷向丝)进行了防治试验。结果表明:利用性诱剂迷向法可使98%以上的梨小食心虫迷失方向,明显减少梨小食心虫的发生数量,减少了被害果,蛀果率只有1.8%,比对照降低了13个百分点,从而增加了梨果产值,同时降低了化学杀虫剂的使用量。

| Abstract: | Sex pheromones trap is a non-pollution pest control technique widely used in orchards.Grapholitha molesta Busck is one of the main pests in pear production areas in Jiangxi Province,China.To find an effective control method,an experiment with sex pheromones to control Grapholitha molesta Busck by mating disruption was carried out in pear orchards in 2012.The results showed that the rate of mating disruption was up to 98%,the number of Grapholitha molesta Busck and boring fruits reduced,and the fruit-boring rate in treatment pear orchards was only 1.8%,which reduced 13 percent point compared with that in the control orchards.Thus the amount of chemical pesticide usage decreased,while the value of pear production per acre increased. |
