摘　　要：玉米坡天牛Pterolophia cervina Gressitt是危害撑绿竹Bambusa pervariabilis×Dendrocalamopsis daii的重要害虫之一，主要以幼虫危害竹竿，该虫在赤水1a发生1代，以老熟幼虫在竹竿蛀道内越冬。翌年4月中旬开始化蛹，蛹期12～20d，5月初成虫开始羽化，经补充营养1～2周开始交配，6月中旬开始产卵，卵期10d左右，6月下旬幼虫开始出现，11月上旬幼虫开始越冬。在对其生物学特性进行系统研究的基础上，提出了切实可行的防治措施。Pterolophia cervina Gressitt was one of the important pests attacking Bambusa pervariabilis × Dendrocalamopsis daii. It had one generation a year in Chishui and overwintered in its bored path in trunk as larva. It pupated in mid-April the next year. The pupal stage lasted for 12 to 20 days. The adult emerged in early May and laid eggs in mid-June. The egg stage lasted for about 10 days. The larva appeared in late June. The control measures of the pest were proposed.
