1.检验了集装箱蚊子在被更多物种入侵后种群数量下降的假设。在埃及伊蚊、白纹伊蚊和三色伊蚊的纯培养和混合培养中，对幼虫竞争假说进行了实验研究。这些实验使用的是在实验室中分解的落叶，而不是之前的大多数使用非天然食物的研究。抗饥饿能力被引入作为衡量幼虫性能和竞争力的新指标。假说是，越成功的幼虫储存的能量越多，抵抗食物缺乏的时间越长。与之前的研究表明埃及斑潜蝇在混合培养中表现更好相反，白纹伊蚊在自然培养时发育更快，存活率更高。使用了食物。表现较好的物种对饥饿的抵抗力更强(例如，使用非天然食物的埃及蜜蜂和使用落叶的白纹伊蚊)。三种容器的饥饿幼虫耗氧量相似，对饥饿的抵抗力相对较低的地下水蚊虫A.taeniorhynchus(Wed.)
1. Hypotheses about declining populations of container-inhabiting Aedes mosquitoes following the invasion by additional species were tested.2. The larval competition hypothesis was studied experimentally in pure and mixed cultures of Aedes aegypti (L.), A.albopictus (Skuse) and A.triseriatus (Say). The experiments used decomposing leaf litter in the laboratory, as opposed to most previous research which used non-natural food.3. Resistance to starvation is introduced as a new measure of larval performance and competitiveness. The hypothesis is that more successful larvae store larger energy reserves and resist the lack of food longer.4. Contrary to previous research showing better performance of A.aegypti in mixed cultures, A.albopictus developed faster and had greater survival when natural. food was used.5. Resistance to starvation was greater in the better performing species (i.e. A.aegypti with non-natural food and A.albopictus with leaf litter). Oxygen consumption by starved larvae was similar in the three container species, and in the ground-water mosquito, A.taeniorhynchus (Wied.), whose resistance to starvation was comparatively very low.
