| Abstract: | Biston marginata Shiraki was an important pest of broad-leaved and broad-leaved mixed forests in Zhongshan city of Guangdong province in recent years. Biological characteristics of Biston marginata was studied in the laboratory and the forest. The results showed that the pest had 1 generation a year and overwintered with the pupa in upper layer of soil in Zhongshan city of Guangdong province. The pupa stage lasted about 9 months. The adult life-span averaged about 8 days, and had not strong phototaxis.A female imago laid at most 1700 eggs in the laboratory. The egg stage lasted an average of 22.1 days, the larval stage 58.2 days and included 6-7 instars. |
