蚊子伊蚊（双翅目：蚊科）自20世纪90年代引入以来迅速蔓延到北美。其建立在竞争对手三列伊蚊和白纹伊蚊占据的容器社区的机制尚不清楚。可能性包括（A）A的时间分离。（B）A.含有异种伊蚊幼虫的地点的数量，和（C）在多个伊蚊的集合中的非加性竞争效应。整个夏天在密苏里州尤里卡附近的橡树山核桃林中取样的容器显示A.比其他种类的伊蚊更早出现在季节中。尽管如此，A。当存在时，在53%的样品中与另一种伊蚊物种共发生，并且在18%的样品中与另两种伊蚊共发生。在田间产卵试验中，A.在林缘容器中产卵量显著高于林内容器，但不避开低密度或高密度的容器。triseriatus、三列拟步行虫A.白纹伊蚊，或两者，与没有幼虫的容器相比。种间竞争效应（表现指数λ′的下降）。triseriatus或A. albopictus单独对A.幼虫在使用的密度不明显，但两种伊蚊结合的效果是显着的负和超级加性的影响，个别种间竞争对手。因此，无论是产卵回避竞争对手或非加性竞争效应有助于入侵成功的A。在北美洲的一个小村庄。不同的季节性物候可能会减少与居民伊蚊的竞争性相互作用。
The mosquito Aedes japonicus (Diptera: Culicidae) has spread rapidly through North America since its introduction in the 1990s. The mechanisms underlying its establishment in container communities occupied by competitors Aedes triseriatus and Aedes albopictus are unclear. Possibilities include (A) temporal separation of A. japonicus from other Aedes, (B) oviposition avoidance by A. japonicus of sites containing heterospecific Aedes larvae, and (C) non-additive competitive effects in assemblages of multiple Aedes. Containers sampled throughout the summer in an oak-hickory forest near Eureka, MO showed peak abundance for A. japonicus occurring significantly earlier in the season than either of the other Aedes species. Despite this, A. japonicus co-occurred with one other Aedes species in 53 % of samples when present, and co-occurred with both other Aedes in 18 % of samples. In a field oviposition experiment, A. japonicus laid significantly more eggs in forest edge containers than in forest interior containers, but did not avoid containers with low or high densities of larvae of A. triseriatus, A. albopictus, or both, compared to containers without larvae. Interspecific competitive effects (measured as decrease in the index of performance, λ′) of A. triseriatus or A. albopictus alone on A. japonicus larvae were not evident at the densities used, but the effect of both Aedes combined was significantly negative and super-additive of effects of individual interspecific competitors. Thus, neither oviposition avoidance of competitors nor non-additive competitive effects contribute to the invasion success of A. japonicus in North America. Distinct seasonal phenology may reduce competitive interactions with resident Aedes.
