Insecticides are traditionally used to control periodical cicadas (Homoptera: Cicadidae) and to reduce associated injury caused by oviposition. However, research has shown that conventional insecticides have low or variable season-long efficacy in reducing injury caused by cicadas. New systemic neonicotinoid insecticides provide excellent levels of control against a variety of sucking insects. We compared the efficacy of a neonicotinoid insecticide, imidacloprid, and a nonchemical control measure, netting, to reduce cicada injury. Netted trees sustained very little injury, whereas unprotected trees were heavily damaged. Fewer eggnests, scars, and flags were observed on trees treated with imidacloprid compared with unprotected trees; however, the hatching of cicada eggs was unaffected by imidacloprid.
传统上，杀虫剂用于控制周期性蝉（同翅目：蝉科）并减少产卵造成的相关损害。然而，研究表明，传统杀虫剂在减少蝉造成的损害方面，整个季节的效果较低或不稳定。新型内吸性新烟碱类杀虫剂对多种刺吸式昆虫具有出色的防治效果。我们比较了一种新烟碱类杀虫剂吡虫啉和一种非化学防治措施（网罩）减少蝉害的效果。用网罩防护的树木几乎没有受到损害，而未受保护的树木则遭到严重破坏。与未受保护的树木相比，用吡虫啉处理的树木上观察到的卵窝、疤痕和旗状物较少；然而，吡虫啉对蝉卵的孵化没有影响。
