摘  要：
昆虫的交配状况对其寿命、繁殖和种群有很大的影响,本文研究了延迟交配对西花蓟马雌雄成虫寿命、产卵量及子代性比的影响。结果表明西花蓟马在羽化0 h、24 h、48 h、96 h后交配其雌、雄成虫的寿命均不受延迟交配时间的影响,而产卵量与交配时间有关,延迟交配24 h和48 h的产卵量高于0 h和96 h的,子代性比随延迟交配时间的延长呈先升后降的趋势,以羽化24 h最高,为2.54∶1,产卵前期随着延迟交配时间的推迟逐渐延长。试验结果为西花蓟马的种群动态预测预报和绿色防控提供了理论基础。

摘  要：
Insect's mating has significant influence on the longevity,fecundity and the population. The effects of delayed mating on adult male and female longevity,fecundity and offspring sex ratio of Frankliniella occidentalis are studied. The results show that the longevity of both female and male adults of Frankliniella occidentalis is not affected by delayed mating at 0 h、24 h、48 h、96 h after emergence. While the fecundity is related to mating time and more eggs are laid at 24 h and 48 h than that at 0 h and 96 h. Offspring sex ratio shows the tendency of increasing firstly and then decreasing,with the highest value of 2. 54∶ 1 female to male at 24 h after emergence. The preoviposition period increases gradually along with the time of delayed mating. The results provide theoretical basis for forecasting the population dynamics and for integrated management of Frankliniella occidentalis.
