摘要
为明确库尔勒市及其周边果园梨木虱的发生规律、为害情况及黄色粘虫板的诱杀效果,于2021年梨木虱成虫活动期,利用黄色粘虫板按五点取样法定期调查成虫诱捕数量,分析其当年发生动态;并于梨木虱活动期之后采用五点取样法分别调查对照区果园与悬挂黄板处理区果园的梨木虱为害率,对比分析黄色粘虫板对梨木虱为害的防控效果。经调查,在库尔勒地区,梨木虱主要在嫩梢期、花期前后、及果实成熟期前为害,全年有两次虫口发生高峰,分别在3月底和4月底。至8月初库尔勒地区梨木虱数量开始大幅减少,其为害几乎贯穿梨树的整个生长期。黄板诱杀试验结果表明,梨木虱成虫出枝活动期是防虫控害的关键时期,处理区梨木虱较对照区为害率减少43.76%。这说明悬挂黄色粘虫板对梨木虱为害有实质性的防控效果。
In order to clarify the occurrence pattern and infestation of pear psylla, and the trapping effect of yellow sticky board in the orchards of Korla and its surrounding areas, the number of adult pear psylla trapped was investigated regularly by five-point sampling method using yellow sticky board during the active period of adult pear psylla in 2021, and the occurrence dynamics of pear psylla was analyzed in that year. The rate of pear psylla infestation in the control orchard and the orchard with hanging yellow sticky board were investigated after the active period of pear psylla, and the prevention and control effects of yellow sticky board on pear psylla were compared and analyzed. After investigation, in the Korla area, the infestation of pear psylla mainly appeared in the shoot period, before and after the flowering period, and before fruit maturity. There were two insect peaks in one year, at the end of March and the end of April respectively. To early August, the quantity of pear psylla began to reduce significantly, and the infestation was almost through the whole growth period of pear trees. The results of yellow sticky board experiment showed that the active period of adult pear psylla was the key period of pest control, the rate of pear psylla infestation in treatment area was decreased by43.76% compared with that of the control area, indicating that hanging yellow sticky board had substantial prevention and control effect on pear psylla infestation.
