丽绿刺蛾[Latoia lepida(Cramer))是柿、菠萝、芒果、椰子、八宝树等数十种农林作物的重要害虫,广泛分布于我国华中、华东、华南等地区。在广州地区,一年发生2～3代,以老熟幼虫于树干茧内越冬,幼虫一般6～8龄。1980年8～9月,我院校区内丽绿刺蛾幼虫患病大量死亡,1981年第1代幼虫又发此病,至第2～3代成为流行病。校区内及其附近绝大部分地区幼虫因此病100%死亡,仅少数地区有极少数幼虫留存下来。

Latoia lepida (Cramer) is an important pest of dozens of agricultural and forestry crops such as persimmon, pineapple, mango, coconut and eight treasures and is widely distributed in central China, East China and South China. In Guangzhou, 2 to 3 generations occur in one year, with mature larvae overwintering in trunk cocoon, larvae generally 6 to 8 years old. From August to September 1980, a large number of larvae of the green moth larvae died in our college. In 1981, the first generation larvae developed the disease again, and the second to third generation became epidemic. Larvae in and around the precincts are therefore 100% fatal, leaving only a few larvae in a few areas.
