摘　　要：采用野外定期采样和室内饲养的方法,观察悬铃木方翅网蝽Corythucha ciliata（Say）在山东济南的生活史;选择5种药剂在悬铃木方翅网蝽第1代卵高峰期开展防治试验。结果表明：悬铃木方翅网蝽在山东济南1 a可发生5代,以成虫群集于寄主开裂的树皮下或地下枯枝落叶中越冬;4月中旬越冬成虫开始上树危害,4月下旬开始产卵,5月中旬第1代卵开始孵化;自7月中旬起世代重叠较为明显,9月下旬第5代成虫陆续越冬。480 g/L毒死蜱EC 500~1000倍液、20%高氯·噻嗪酮EC 500倍液和0.7%辛硫·高氯氟EC 500倍液施药5 d后,悬铃木方翅网蝽第1代卵未孵化率均达到90%以上,是卵早期防治的可选药剂;4.2%高氯·甲维盐EC和4.5%高效氯氰菊酯EC直接杀卵效果不佳,但对初孵若虫的致死率达到100%,是卵后期施药的较好药剂。Life history of the sycamore lace bug,Corythucha ciliata,was observed in Jinan city,Shandong province by the methods of field sampling and indoor feeding,and a control experiment was carried out at the peak time of the egg stage of the first generation with 5 insecticides. Results showed C.ciliata had five generations a year in Jinan and overw intered as adults under loose bark of the trees or in the litter. Adults began to make damage in middle April and laid eggs at the end of April. The nymphs of the first generation was found in middle May. Since mid July,the overlapping of generations was obvious. In late September,the fifth generation adults began to overw inter. The results of the control experiment showed that chlorpyrifos 480 g/L EC 500 ~ 1000 times,beta-cypermethrin·buprofezin 20%EC 500 times and phoxim·lamba-cyhalothrin 0. 7% EC 500 times could be used as an optional medicine for early prevention and control. The hatchability of the first generation eggs was below 10% 5days after the treatment. Although the direct ovicidal effect of beta-cypermethrin·emamectin benzoate4. 2% EC and beta-cypermethrin 4. 5% EC was poor,their lethality rate on the first instar nymphs was100%. Therefore,they were good choice in the late stage of egg development.
