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。防治宜用药帘击杀 Through the observation of indoor rearing and field investigation, the basic biological characteristics such as the life history of Maculostella lactiflora were clarified, and corresponding control measures were proposed accordingly. The pest generations overlap obviously, the average daily temperature of 10 ℃ is the temperature of the initial activity after the winter, each generation of about 20 ~ 25d, which an average of 4.68d before oviposition, an average of 2.14d eggs, one, two, three The larval instars were 3.42d, 3.2d and 5.46d, respectively. The average pupal period was 6.64d. December mature larvae, pupae, adult wintering. Prevention should be used to kill the drug curtain
