文摘内容 Lasiognatha cellifera was one of the main defoliators for the Aegiceras corniculatum which was main tree of mangrove, and identified as new record of species in China L. cellifera had 7 generations per year in Zhangzhou area, Fujian Province and overwintered as pupa in the rolled leaf. Adult moth emerged in last-May, mating and laying egg on back of leaf soon. Egg period lasted 5 d, larvae period lasted 13—17 d, pupa periods lasted about 6 d but overwinter-pupa lasted about 150d, adult moth life-span was 4—5 d. The periods were related to the diversification of temperature, and the periods decreased with the increase of temperature. A. corniculatum in the front of seashore were harmed seriously for the reason that they growed weakly and L. cellifera was not adept in flying. Protecting natural enemies such as bird, parasitism etc., alluring adult moth,spraying Dimilin m in 2 000 concentration when it occurred seriously will control L. cellifera effectively。
