摘要
为推广梨小食心虫迷向剂在果园的防控应用,选择陕西白水县西方城村和可仙村的苹果园、彬州市西沟村的梨园及大荔县羌东村的桃园进行梨小食心虫迷向剂推广试验,以同村临近果园为对照,并在迷向区和对照区采用性诱剂监测调查果园梨小食心虫的发生动态,评价性信息素迷向剂对梨小食心虫的田间防控效果。结果表明,迷向剂处理区梨小食心虫的种群数量显著低于对照区。苹果园、梨园和桃园3个迷向剂处理区梨小食心虫的迷向率分别为97.12%、95.65%和95.36%;虫害出现初期折梢防效分别为80.82%、80.82%、77.70%;果实成熟期蛀果防效分别为92.38%、94.50%、90.43%。梨小食心虫性信息素迷向剂可有效降低果园梨小食心虫引起的蛀梢和蛀果数量,在苹果园、梨园和桃园中对梨小食心虫具有很好的防控效果。
To evaluate the actual control effect of disrupting mating with sex pheromones to Grapholitha molesta, the study was carried on in Shaanxi province that including Xifangcheng village and Kexian village in Baishui county, Xigou village in Binzhou city,Qiangdong village in Dali County. The control was in the same village. The population dynamics of Grapholitha molesta and the control efficiency of sex pheromone to Grapholitha molesta were monitored and evaluated in areas with sex pheromone attractants and control areas of apple orchards, pear orchards and peach orchards. The results showed that the population quantity of Grapholitha molesta in areas with sex pheromone treatment was significantly lower than that of in the areas with control of apple orchards, pear orchards and peach orchards. In apple orchards, pear orchards and peach orchards, the mating disruption rates of Grapholitha molesta were 97.12%,95.65% and 95.36%, respectively, the efficiency of sex pheromone on the control of damaged shoots in the early occurrence stage of Grapholitha molesta were 80.82%, 80.82% and 77.70%, respectively, the efficiency of sex pheromone on the control of damaged fruits in the maturation period were 92.38%, 94.50% and 90.43%, respectively. The results demonstrated that sex pheromone traps effectively reduced the number of shoots and fruits borer caused by Grapholitha molesta, and the mating disruption of Grapholitha molesta based on sex pheromone was a good pest management strategy in orchards.
