摘　　要：杨潜叶跳象Rhynchaenus empopulifolis是危害杨树的食叶害虫,本文首次报道其在泰安地区发生。室内饲养和林间调查结合,观察泰安地区杨潜叶跳象形态特征、生物学特性及危害特点,初步探索其预蛹期化学药剂防治。结果表明:200 g/L氯虫苯甲酰胺悬浮剂(SC)800,1 200倍液和2.5%高效氯氟氰菊酯微乳剂(ME)400,600倍液4个处理间差异不显著,对杨潜叶跳象预蛹的防治效果均超过86%,与另2个处理差异极显著。200 g/L氯虫苯甲酰胺SC 3个浓度处理与清水对照处理的天敌寄生率差异不显著,与2.5%高效氯氟氰菊酯ME相比,对寄生性天敌更安全。Rhynchaenus empopulifolis Chen is a defoliator against Populus L.This is the first report of its occurrence in Tai'an city.The bionomics of R.empopulifolis in Tai'an were determined by indoor rearing and field investigation,and the chemical control method at adjacent pupal stage was preliminary explored.The results showed that the control efficacy of chlorantraniliprole 200 g/L SC diluted 800 and 1200 times and lambda-cyhalothrin 2.5%ME diluted 400 and 600 times were higher than 86%without significant difference,but with significant differences compared with another two treatments.The parasitization rate of natural enemies of R.empopulifoli had no significant differences between the three treatments of chlorantraniliprole 200 g/L SC and water control.Chlorantraniliprole 200 g/L SC for natural enemy was safer than lambda-cyhalothrin 2.5%ME.
