摘要
本文报告丽蝇蛹集金小蜂寿命与寄生率及产仔蜂数量关系的初步研究。结果表明该蜂实验种群的雌雄性比为4:1。雌蜂累计平均寿命为10.42天,平均日存活率为85％。雌蜂3～7日龄时寄生率最高,产仔蜂量也最大。平均每头雌蜂一生产仔蜂473头,平均每头雌蜂每天产37.5±22.35头。
The paper reports the results of study on the relationships among the longevity, the parasitic ratio and productiveness of Nasonia vitripenn. It was found that the sex ratio among the wasp progeny was 4 females to 1 male. The average life-span of the females was 10.42 days. the average daily survival was 85％. The higher parasitic ratio and more progeny numbers produced by a femal were occurred in the age of 3-7 days Pemals asitive progeny lifesp an. The numbers of produced by a female wasp in her life span was 473 and 37.5 per day in the laboratory.
