摘  要:
桉蝙蛾Endoclyta signifier是速生桉主要蛀干害虫。连续3 a在发生区通过定点、定期、定量采集幼虫,设立网棚观察和室内饲养,研究该虫生物学习性。桉蝙蛾在广西博白县1 a或2 a发生1代,成虫4月上旬羽化,有2种色型,雌虫产卵量大,卵粒散落地表,4月中旬幼虫开始孵化,共12龄,低龄幼虫在表土层生活,3龄至老熟幼虫在寄主枝干内独立蛀食,6月至翌年1月是幼虫主要危害期,2月下旬化蛹。在博白地区该虫寄主约有28种。

摘  要:
Endoclyta signifier is a main stem borer on Eucalyptus. The bionomics of the pest was studied for 3 consecutive years in the infested area by means of quantitatively collecting larvae at fixed point and time,net shed observation and indoor rearing. In Bobai county,Guangxi Province,E. signifier has one generation 1 or 2 years. The adults emerge in early April with 2 color types. The fecundity of the female is high and the eggs scatter on the ground. The larvae hatch in mid April with a total of 12 instars. The young larvae live in the soil while the larvae between the 3rd and the 12 th instars bore into the host trunks and branches. The larvae cause damage mainly in the period from June to January the next year and pupate in late February.
