摘　　要：沟眶象Eucryptorrhynchus scrobiculatus和臭椿沟眶象Eucryptorrhynchus brandti是中国北方严重危害臭椿的钻蛀性害虫。为开发这两种象虫的诱捕技术,本文比较了8种不同波长的LED灯、黑光灯、频振式杀虫灯,糖醋液和臭椿木段对两种象甲的引诱效果,并在室内、野外进行回捕试验。室内不同诱源选择结果表明,沟眶象对臭椿木段最敏感,臭椿沟眶象对频振式杀虫灯最敏感;在室内,臭椿木段对沟眶象的回捕率最高,频振式杀虫灯对臭椿沟眶象的回捕率最高;在野外,频振式杀虫灯对沟眶象和臭椿沟眶象的回捕率均最高。本研究建议使用频振式杀虫灯监测和防治沟眶象和臭椿沟眶象。Eucryptorrhynchus scrobiculatus and E.brandti(Coleoptera:Curculionidae)are destructive trunk borer pests on Ailanthus altissima in North of China.In order to develop these two weevils trapping technology,this study compared the attracting effect of eight light-emitting diodes(LEDs),black-light,frequency trembler grid lamps,sugar-vinegar mixture and the trunk of tree-of-heaven to E.scrobiculatus and E.brandti,and the recapture test was carried out in the indoor and field.The results of indoor selection of different attractants demonstrated that,E.scrobiculatus was the most sensitive to the trunk of tree-of-heaven and E.brandti was the most sensitive to frequency trembler grid lamps;The recaptured rate of the trunk of tree-of-heaven to E.scrobiculatus was the largest in the indoor recapture test while frequency trembler grid lamps was the largest to E.brandti.The recaptured rate of frequency trembler grid lamps was the largest to E.scrobiculatus and E.brandti in field recapture test.This study is recommended frequency trembler grid lamps to survey and control of E.scrobiculatus and E.brandti.
