竹笋禾夜蛾生物学特性及其防治

竹笋禾夜蛾是福建省竹林的主要害虫，该虫在福建一年发生1代,以卵越冬,翌年2月中旬开始孵化，幼虫6龄,幼虫期51—80天,蛹期17—29天。每雌一生产卵84—467粒．成虫寿命6—17天。该虫的综合防治应以林业防治为主,9月份开始林地除草灭虫；3月初以化学农药喷杂革治虫,4月初出笋后对笋喷药2次；成虫羽化盛期点灯诱蛾等坊治措施,可以有效地控制虫害。

Biology of Oligia vulgaris (Butler) and its control

Oligia vulgaris (Bulter) is a main pest of bamboo forest in Fujian China. It has one generation a year and overwinters with egg in Fujian. Larvae hatch in mid February the next year. Ordinarily the larval stage with six instars lasted 51-80 days, the pupa stage 17-19 days and the adult stage 6-13 days. The integrated control of the pest should be based on forest control. Killing weeds in September, spraying insecticides on weesd in early March or on bamboo shoot two times when it emerge in early April, and lighting to induce adults when if mostly emerge are efficient control methods.
