| 中文摘要: |
| 双齿锤角叶蜂（Odontocimbex svenhediniMalaise）是近年发生于甘肃天水刺五加（Acanthopanax senticosus）的一种食叶新害虫，其寄主刺五加是首次报道。该虫1年发生1代，翌年4月上旬越冬预蛹开始化蛹，4月中旬成虫羽化，下旬开始产卵，卵产于叶背面或正面主脉周围叶表皮下，卵期9~11 d；幼虫食叶为害，共5龄，6月上旬至7月中旬为猖獗为害期，6月下旬幼虫开始老熟，老熟幼虫于寄主或周围非寄主植物枝条结茧越夏越冬。5月中下旬3龄前幼虫期，用25%灭幼脲悬浮剂1 500倍液，防效达95%以上。用3%高渗苯氧威乳油或1.8%阿维菌素乳油5 000 倍液，防治3龄后幼虫，防效达92%以上。 |
| 英文摘要: |
| Odontocimbex svenhedini Malaise is a new leaf eating pest on Acanthopanax senticosus in Tianshui,Gansu Province. It is the first time that A.senticosus was reported as a host. This insect had one generation per year; the overwintering prepupae began to pupate in early April the second year. The adults emerged in mid April and laid eggs in late April. Eggs were laid on the back of the leaves or in epidermis around main veins. The egg stage lasted for 9-11 days; the larvae ate leaves, with 5 instar, and serious harm came from early June to mid July. In late June, larvae start to become mature, and the fully grown larvae oversummered and overwintered by producing cocoon in the branches of host or the surrounding non host plants. In mid and late May, the control effect of the larvae prior to 3rd instar treated,with 25% chlorbenzuron suspension 1 500 × dilution was above 95%. 3% fenoxycarb EC or 1.8% abamectin EC 5 000 ×dilution achieved a control effect of more than 92% for the larvae after 3rd instar. |
