摘　　要： 本研究证实了节瓜蓟马Thrips palmi孤雌生殖属于产雄性孤雌生殖(arrhenotoky)。在恒温(25±0.5℃)下,节瓜蓟马成虫两种生殖方式的产卵力比较结果表明,两种生殖方式下的成虫产卵力没有显著差异。两性生殖与孤雌生殖下成虫平均产卵量分别为55.69粒和54.90粒,平均日产卵量分别为2.455粒/d和2.275粒/d,平均寿命分别是22.67d和23.96d;产卵前期则均为2.25d。雄性个体平均寿命为19.33d,它与雌性个体平均寿命差异亦不显著。 Parthenogenesis of Thrips palmi Karny was confirmed as arrhenotoky in this paper. There was a significant difference between the fecundity of virgin females and that of mated females. At constant temperature (25℃). mated females laid average of 55. 67 eggs during their life span, while virgin females laid average of 54. 90 eggs. Mated females laid 2. 455 eggs per day, while virgin females laid 2. 275 eggs per day. The pre - ovipositiom period of both of them was 2. 25 days. The average longevity of mated females was 22. 67 days, while that of virgin fe-males was 23. 98 days. The average longevity of males was 19. 33 days, There was no signifi-cant difference, between mated and virgin females.
