| Abstract: | Ocinara variana is one of important pests on Ficus plants in southern China. It has 6 generations a year in Guangzhou. At 25-27℃, the developmental durations of egg, larvae, pupa and adult were 3-4, 12-15, 3-5, 3-5 days, respectively. The average fecundity of the moth was 200 eggs per female, ranging from 30 to 400 eggs per female. Two peaks of population dynamics occurred each year. in spring （from April to May） and fall （from September to October） respecfively. |
