容器伊蚊是人类虫媒病毒最重要的载体（即，登革热、基孔肯雅热、寨卡病毒或黄热病）。入侵和本地容器伊蚊属。在特定的产卵环境中利用天然和人工容器进行产卵。几种容器伊蚊属。显示“跳跃产卵”行为，其描述了在单个生殖营养周期期间卵在多个容器中的分布。在这项研究中，我们比较了个人跳过产卵行为使用相同的八杯测试舞台与三个容器伊蚊种：埃及伊蚊（林奈），白纹伊蚊（Skuse），和三列伊蚊（说）。我们应用离散指数，聚集统计量，个体蚊子的产卵模式，以评估跳跃产卵行为。埃及伊蚊Aedes aegypti和Ae.白纹伊蚊比Ae利用更多的杯子，并且在杯子之间更均匀地分配卵。在营养丰富的产卵介质（橡树叶浸液）条件下，对三列绒螯蟹进行产卵。当提出一个营养不丰富（自来水）产卵媒体，无论是Ae。埃及伊蚊和埃及伊蚊。白纹伊蚊增加了卵的传播行为。白纹伊蚊没有修改跳跃产卵行为时，饲养和评估下降的环境条件下，诱导滞育卵生产。这项研究表明，特定的产卵地点条件影响跳跃产卵行为与“首选”网站接收更高数量的鸡蛋从任何给定的个人和“非首选”网站接收有限的贡献的鸡蛋。需要进一步了解跳跃产卵行为，以充分利用自动传播陷阱技术，其中跳跃产卵的女性传播一个有效的杀幼虫剂产卵地点之间的环境。
Container Aedes mosquitoes are the most important vectors of human arboviruses (i.e., dengue, chikungunya, Zika, or yellow fever). Invasive and native container Aedes spp. potentially utilize natural and artificial containers in specific environments for oviposition. Several container Aedes spp. display 'skip-oviposition' behavior, which describes the distribution of eggs among multiple containers during a single gonotrophic cycle. In this study, we compared individual skip-oviposition behavior using identical eight-cup testing arenas with three container Aedes species: Aedes aegypti (Linnaeus), Aedes albopictus (Skuse), and Aedes triseriatus (Say). We applied the index of dispersion, an aggregation statistic, to individual mosquitoes' oviposition patterns to assess skip-oviposition behavior. Aedes aegypti and Ae. albopictus utilized more cups and distributed eggs more evenly among cups than Ae. triseriatus under nutritionally enriched oviposition media (oak leaf infusion) conditions. When presented with a nutritionally unenriched (tap water) oviposition media, both Ae. aegypti and Ae. albopictus increased egg spreading behavior. Aedes albopictus did not modify skip-oviposition behavior when reared and assessed under fall-like environmental conditions, which induce diapause egg production. This study indicates specific oviposition site conditions influence skip-oviposition behavior with 'preferred' sites receiving higher amounts of eggs from any given individual and 'non-preferred' sites receive a limited contribution of eggs. A further understanding of skip-oviposition behavior is needed to make the best use of autodissemination trap technology in which skip-ovipositing females spread a potent larvicide among oviposition sites within the environment.
