黄斑露尾甲生物学特性及防治研究

Bionomics and Control of Carpophilus hemipterus (Linne).

通过室内饲养观察及实地调查，明确了黄斑露尾甲生活史等基本生物学特性，并据此提出相应防治对策。该虫世代重叠明显，日平均气温达１０℃为越冬后起始活动温度，每代历期约２０～２５ｄ，其中产卵前期平均４．６８ｄ，卵期平均２．１４ｄ，一、二、三龄幼虫期分别为３．４２ｄ、３．２ｄ和５．４６ｄ，蛹期平均为６．６４ｄ。１２月以老熟幼虫、蛹、成虫越冬。

Carpophilus hemipterus (Linne) is one of the most destructive insects pest in distillery.The life cycle and the fundamental biology of the pest were studied in 1992～1993.10～20 overlaped generations of the insect can yearly survive in Maanshan,Anhui Province.The preoviposition period was 4 68 days,egg stage lasted 2 14 days,the first,second and third instar larva stages were 3 42,3 2 and 5 46 days,respectively.The pest overwintered in old larva,pupa and adult from December.By using the net screen sprayed with Quchongjing Ⅰor Quchonjing Ⅱ the pest could be effectively controlled.
