两株尖音库蚊（Culex pipiens（s.l.）不同地理起源的植物进行杂交，杂交往往在一个或两个方向上不育1。这种不亲和性被认为是细胞质的，因为菌株的可杂交性是由其母系决定的2。不相容性在某种程度上是由立克次体样细菌共生体感染引起的，因为共生体的去除消除了不相容性3。在美国株的杂交中未观察到不亲和性。pipiens 4 -7.另一方面，世界其他地区的大多数工人谁越过C。pipiens菌株已经注意到不相容性7 -14，尽管没有在田间收集到不相容卵筏的报道。我们现在报告同域美洲株的杂交不亲和性。pipiens和收集不兼容的卵筏在外地。
When two strains ofCulex pipiens(s.l.) of different geographical origin are cross-mated, the cross is frequently sterile in one or both directions1. Such incompatibility is said to be cytoplasmic because the crossability of a strain is determined by its maternal lineage2. The incompatibility is caused in some way by infection with a rickettsia-like bacterial symbiote, as removal of the symbiote abolishes the incompatibility3. Incompatibility has not been observed in crosses of American strains ofC. pipiens4–7. On the other hand, most workers in other parts of the world who have crossedC. pipiensstrains have noticed incompatibility7–14, although there are no reports of incompatible egg rafts being collected in the field. We now report incompatibility in crosses of sympatric American strains ofC. pipiensand the collection of incompatible egg rafts in the field.
