【摘要】 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．更多还原

【Abstract】 The sexual ratio of adults of the pest Liriomyza sativae (Diptera: gromyzidae) was 1: 1; themean lifespan was 8 .7 ～ 12.6 days; the mean fecundity was 70.5 ～ 120.8;the peak oviposition was in 3～7 days after emergence; and their mealing, mating and laying were only in the daytime. The eggehatched both in the day and night and the hatching rate were above 90.8%. The larvae mealed both inthe day and night, and the mealing amounts of various instars varied on different crops. The pupation andemergence of the pest occurred generally before 10 am.; and 95. 3% of the pupae got down into soil. Thepest developed for 18 generations in 1995 and did not diapause in overwintering. The results showed thatthe pest could damag more than 50 varieties of vegetables of 13 families in Guangzhou region.更多还原
