成虫取食、交尾均于白天进行，平均寿命8．7～12．6d，平均每雌产卵量70．5～120．8粒，产卵高峰在羽化后3～7d内．卵在白天和晚上均可孵化，孵化率90．8％以上．幼虫白天和晚上均可取食，不同虫龄和在不同作物上，其取食量不同．化蛹一般在上午10时前进行，95．3％掉到土壤中．羽化一般在上午10时前，性比1：1．虫态历期与温度成反相关．1995年在广州地区年发生18个世代，发生为害高峰在6～11月，可为害13个科50多种蔬菜；无滞育越冬现象．
Adult feeding, mating were carried out during the day, the average life expectancy 8.7 ~ 12.6d, the average number of fecundity per female 70.5 ~ 120.8, spawning peak in 3 ~ 7d after emergence. Eggs hatch during the day and night, hatching rate of 90.8%. Larvae can be fed during the day and night, different insects age and in different crops, their intake is different. The pupa generally goes before 10 o’clock in the morning and 95.3% falls to the soil. Feather usually before 10 o’clock in the morning, sex ratio 1: 1. Insect state is inversely related to temperature and temperature. Occurred in 1995 in Guangzhou area 18 generations, the highest peak in June to November, 13 families can damage more than 50 kinds of vegetables; no diapause wintering phenomenon.
