运城酥梨产区梨小食心虫发生动态监测及性诱剂诱捕防控效果调查

为明确梨小食心虫在山西省运城市的发生规律和性诱剂诱捕的田间防治效果,利用性诱剂三角形诱捕器对梨小食心虫成虫的发生动态进行了系统监测,并对两种性诱剂诱捕器在田间的防治效果进行了调查。监测结果表明,监测期间梨小食心虫成虫发生有3个高峰期：第一个高峰期在6月15日—7月1日,第二个高峰期在7月23—29日,第三个高峰期在8月28日—9月3日。性诱剂诱捕的防治效果调查表明,两种性诱剂诱捕器对梨小食心虫成虫的防治均有效果,且三角形诱捕器效果较好。本研究明确了梨小食心虫成虫在运城地区的发生动态及性诱剂诱捕的防治效果,为运城地区梨园梨小食心虫的预测预报及绿色防治提供了科学依据。

Occurrence Regularity of Grapholitha molesta Adults in Yuncheng Area and Control Effect of Sex Pheromone Traps

To clarify the occurrence regularity of Grapholitha molesta adults and the control effect of sex pheromone traps, the occurrence regularity of G. molesta adults was systematically monitored with triangular sex pheromone traps and the control effect of two sex pheromone traps were studied. The results indicated that the peak occurrence time of G. molesta adults appeared three times. The first peak was from June 15 to July 1, the second peak was from July 23 to 29, and the third peak was from August 28 to September 3. The study on the control effect of the sex pheromone trap showed that both sex pheromone traps had control effects on G. molesta adults, and the triangular trap had better effect. The results clarifies the occurrence regularity and the control effect of sex pheromone traps for G. molesta adults in Yuncheng area, which could provide a scientific basis for the pest prediction and control.
