The existence of pre-mating and post-mating barriers between Culex pipiens L. populations and the possibility of interbreeding between autogenous and anautogenous mosquitoes were examined. Test mosquito populations were stenogamous with > 83% insemination rates in 20 x 20 x 20 cm cages, regardless of autogeny rates ranging from 10 to 91%. Bi-directional crosses between three geographical populations resulted in > 80% hatch rates, indicating full cytoplasmic compatibility. Both autogenous and anautogenous Cx. pipiens individuals were encountered in the progenies of autogenous or anautogenous female parents. Moreover, more than 75% of field caught females produced mixed progenies. thus, the authors suggest there is no limitation for hybridization between Cx. pipiens mosquitoes in Egypt due to the lack of premating and post-mating barriers.
研究了致倦库蚊种群之间交配前和交配后的障碍以及自育和非自育蚊子之间杂交的可能性。在20×20×20厘米的笼子里，测试蚊子种群是近亲交配的，受精率>83%，无论自育率在10%到91%之间。三个地理种群之间的双向杂交产生了>80%的孵化率，表明细胞质完全兼容。自育和非自育的致倦库蚊个体都出现在自育或非自育雌性亲本的后代中。此外，超过75%的野外捕获雌性产生了混合后代。因此，作者认为由于缺乏交配前和交配后的障碍，埃及致倦库蚊之间的杂交没有限制。
