摘要
为明确梨小食心虫性信息素迷向散发器对桃园梨小食心虫[Grapholitha molesta(Busck)]的防治效果和合理的使用密度,于2018年采用梨小食心虫性信息素迷向散发器在江苏省句容市桃园进行迷向防治试验。结果表明,450、600、990根/hm^(2)处理对梨小食心虫均有较好的防效,且高密度处理迷向效果更佳;梨小食心虫折梢率和蛀果率均低于对照桃园,450、600、990根/hm^(2)处理折梢防治效果分别为94.79%、96.58%和96.90%,蛀果防治效果分别为92.55%、96.09%和97.51%。综合防效和成本考虑,桃园中性信息素环境浓度以600根/hm^(2)为宜。
In order to research the control effect and reasonable using density by sex pheromoneisotropic vector of Grapholitha molesta,using the technology the control test was carried outin peach orchard.The results showed that better control effect were 450,600 and 990 pieces/hm^(2) treatment respectively,height density treatment was better.Broken end rate and borer fruit rate of Grapholitha molesta were lower than the control,control effect of broken end rate of 450,600 and 990 pieces/hm^(2) treatment were 94.79%,96.58% and 96.90%,respectively,and control effect borer fruit rate were 92.55%,96.09% and 97.51%,respectively.Environmental concentration of sex pheromone was 600 pieces/hm^(2) to be reasonable from considering the comprehensive prevention effect and cost.
