摘　　要：2015年3月—2016年6月,每个月定期对杨叶肖槿(Thespesia populnea)虫害进行调查。结果表明,杨叶肖槿栽培过程中害虫种类主要有7种,隶属5目7科。其中棉卷叶野螟(Sylepta derogate)、瘤缘蝽(Acanthocoris scaber)和八点广翅蜡蝉(Ricania speculum)最常发生且为害最严重。在栽培过程中,可采取如下防治措施:(1)棉卷叶野螟可利用黑光灯诱杀成虫,在产卵盛期至卵孵化盛期喷菊酯类杀虫剂;(2)瘤缘蝽的防治应及时清除枯枝落叶及林边杂草,摘除有卵的叶片,在若虫孵化盛期选择高效、低毒、低残留农药施药;(3)八点广翅蜡蝉可采用化学药剂进行防治,也可悬挂诱虫灯诱杀成虫。Insect pests on Thespesia populnea were regularly investigated from March 2015 to June 2016. There were 7 main species of insect pests infecting T. populnea plants during the period of cultivation, belonging to 5 orders and 7 families. Sylepta derogate, Acanthocoris scaber and Ricania speculum were the most serious insect pests.There were three controlling measures against those three insect pests should be done in cultivation.（1）S. derogate could be killed by black light lamps or pyrethroids.（2）A. scaber should be killed by high efficiency, low toxicity and low residuepesticide. Dead branches and leaves and leaves with eggs should be cleared timely to reduce the insect pests.（3）R. speculum could be killed by chemical agent or trap lamps.
