稻象甲Echinocnemus squameus Billberg属鞘翅目象虫科多型象亚科Notorinae,是水稻的重要害虫之一。以往该虫在我省以幼虫为害本田最烈:近年来成虫为害早、晚稻秧苗和早插本田的稻苗十分严重,特别是早稻秧苗,被害后,叶片大部折断,漂浮水面,似牛吃过一样,虽不死亡,但严重影响秧苗生长,秧苗素质极差。部分秧田在秧针期开始便反复遭害,幼苗被咬断后长起,长起又被咬断,最后终因养分耗尽而死亡。

Echinocnemus squameus Billberg is a member of the genus Coleoptera, Coleoptera, Notorinae, which is one of the important pests of rice. In the past the insect larvae in our province the most fierce Honda: In recent years, adult damage early, late rice seedlings and early Honda rice seedlings is very serious, especially in early rice seedlings, most of the leaves after the break, floating surface, like cattle eat The same, although not dead, but seriously affect the growth of seedlings, poor quality of seedlings. Part of the seedling in the beginning of the needle seedlings will be repeatedly victimized, seedlings snapped off after the long, long and again snapped off, and finally died of nutrient depletion.
