对芦笋上的14点负泥虫的生活史、习性和防治措施进行了研究。结果表明,该害虫在烟台芦笋产区1年发生2代,世代重叠,以成虫在芦笋根际地下枯茎内越冬。翌年4月中旬气温达10℃以上时开始出蛰,5～10月为其生殖繁衍和为害时期,11月中下旬开始寻找场所越冬。据此提出,应贯彻“预防为主,综合防治”的植保工作方针,抓住越冬成虫出蛰繁衍初期防治,严防扩散,并压低虫源基数,进而控制为害。
The life history, habits and control measures of 14-point negative insect on asparagus were studied. The results showed that the pest occurred in Yantai asparagus producing area two generations a generation, overlapping generations to adult asparagus rhizosphere underground winter wintering. In mid-April the following year the temperature reached 10 ℃ above when the sting began, 5 to October for its reproductive reproduction and damage period, in late November to find the place for winter. Accordingly, it is suggested that the principle of plant protection with prevention as the mainstay and comprehensive prevention and control should be implemented to seize the prevention and control of overwintering adult worms in the early stages of development, prevent proliferation, and reduce the number of insect pests and control them.
