摘要:

为明确库尔勒市及其周边果园香梨茎蜂的发生规律和为害情况及黄色粘虫板的诱杀效果,于2020年香梨茎蜂成虫活动期,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;并于香梨茎蜂活动期之后采用五点取样法分别调查未悬挂黄板果园与悬挂黄板果园的香梨茎蜂为害率,对比分析黄色粘虫板对香梨茎蜂为害的防控效果。经调查,香梨茎蜂主要在梨树花期前后为害,在4月中旬达到发生高峰期,成虫活动时间为19天(4月6—24日),主要通过雌成虫产卵行为为害新梢,在未挂黄板果园平均为害率为29.13%,悬挂黄板的香梨园平均为害率为13.60%,相较于未挂黄板的对照香梨园为害减少率为52.41%。香梨茎蜂成虫出枝活动期是防虫控害的关键时期,悬挂黄色粘虫板对香梨茎蜂的为害有明显的防控效果。建议当地4月在香梨园中大面积使用黄色粘虫板诱杀成虫,减少香梨茎蜂的为害。

Abstract:

The paper aims to clarify the occurrence and damage of Janus piriodorus on pear in orchards of Korla and its surrounding areas, and the trapping effect of using yellow sticky insect board. In the active period of J. piriodorus in 2020, the number of adult trapped was investigated regularly by using the five-point sampling method with the yellow trap board, and the occurrence dynamics were analyzed. After the active period, the damage rate of J. piriodorus in orchards without hanging yellow sticky insect board and hanging yellow board was investigated by five-point sampling method, and the control effect of yellow trap board on J. piriodorus was analyzed. Through the investigation, it is found that the J. piriodorus mainly harms pear trees around the flowering period, and its occurrence reaches the peak in mid-April. The J. piriodorus activity time is about 19 days (April 6-April 24), it mainly harms the new tips through oviposition behavior of the female, and the damage rate is averagely 29.13% in orchards without yellow trap board, while the damage rate is averagely 13.60% in orchards with yellow trap board, and the reduction rate was 52.41%. The active period of adult of J. piriodorus is the key period for pest control. The hanging of yellow trap board has obvious control effect on J. piriodorus. Therefore, it is suggested to use yellow sticky insect boards to trap and kill adults of J. piriodorus in April to reduce its harm.
