摘要 为明确当前主要防治药剂的效果并筛选高效防治药剂,选用10%甲维·吡虫啉可溶液剂、36%杀虫双水剂和20%杀虫单水剂(保林三号)等8种药剂,采用打孔注药的方式,进行了不同药剂防治效果的比较。结果表明,10%甲维·吡虫啉可溶液剂打孔注药防治方翅网蝽效果最好,防治后3、7和15 d,校正死亡率均可达90%以上,分别为90.8%、94.3%和93.1%,显著高于其他处理。

Abstract In order to clarify the effect of the main control pesticides and select effective pesticides, eight kinds of pesticides, including 10% Emamectin imidacloprid solution, 10% Bisultap and 20% monosultap (Baolin No.3), were selected to compare the control effects of different pesticides by hole injection. The results showed that 10% Emamectin · imidacloprid solution had the best control effect on Corythucha ciliate. 3,7, and 15 days after controlling, the corrected mortality rate could reach more than 90%, which were 90.8%, 94.3% and 93.1%, respectively, and were significantly higher than other treatments.

懸铃木(法国梧桐)方翅网蝽(Corythucha ciliate Say)原产于美国中东部地区[1],属于半翅目网蝽科,于2002年首先在我国长沙发现,2006年又在武汉大发生,并首次被确定为外来入侵种[2-3],目前在我国多地均有发生,甚至2020年新疆也有发现[4],被我国多地评价为中度值中度偏高危险性有害生物[1,5-7],已增列为我国林业危险性有害生物名单。悬铃木方翅网蝽主要以成虫、若虫危害悬铃木(Platanus spp.)[6-7],也可传播悬铃木溃疡病和法国梧桐炭疽病等真菌病害,致使叶片黄化脱落,甚至导致植株死亡[8-10]。传统的防治措施以树冠喷雾防治为主,但喷雾防治对环境污染较大,城区喷雾施药难度大,打孔注药作为一种环保施药方式逐步得到广泛应用[11-12]。笔者通过比较不同药剂打孔注药对法国梧桐方翅网蝽的防治效果,筛选出高效防治药剂,用于安徽省法国梧桐方翅网蝽的有效防治。
