摘要:

为明确梨小食心虫迷向丝在临朐樱桃园的田间使用效果,2021年在樱桃园悬挂迷向丝,采用田间调查的方法监测梨小食心虫的发生动态,并比较不同数量迷向丝的迷向效果以及蛀梢防效等。结果表明,樱桃园梨小食心虫4月初—7月均有发生,其中4月26日和6月14日梨小食心虫成虫的发生数量最多,诱捕数量分别为33、38头/诱捕器。300根/hm2迷向丝的处理迷向率最低,450、600根/hm2迷向丝的处理迷向率差异不显著,均在89%以上。使用迷向丝蛀梢率明显低于对照区,使用迷向丝对蛀梢的防治效果在80%以上。根据梨小食心虫的发生关键时期,悬挂450根/hm2的迷向丝可基本控制梨小食心虫的发生和为害。

Abstract:

To clarify the application effect of Grapholitha molesta (oriental fruit moth, OFM) in Linqu cherry orchards, a field survey was conducted to monitor the occurrence dynamics of the oriental fruit moth and compared the mating disruption effect and rate of shoot decay in Linqu cherry orchards in 2021 by hanging disorientated wire. The results showed that the occurrence of G. molesta was from early April to July, and the occurrence of G. molesta adults was the highest on April 26 and June 14, with 33 and 38 adults per trap, respectively. After comparing different numbers of disorientated wire, it was found that the mating disruption rate under 300 clips/hm2 treatment was the lowest, while that under 450 clips/hm2 and 600 clips/hm2 treatments had no significant difference, both were above 89%. The shoot decay rate of the treated orchards was obviously lower than that of the control area, and the control effect on shoot decay was more than 80%. According to the critical periods of the occurrence of G. molesta, hanging 450 clips/hm2 of disorientated wire can basically control the occurrence and avoid the damage of G. molesta.
