埃及伊蚊Aedes aegypti（L.）AE. albopictus（Skuse）和白纹伊蚊Ae.在实验室和田间条件下，对三列小蠹（Triseriatus（Say））的三种和双种混合种群进行了研究。竞争压力（证明的平均时间为第一，50，和75%的化蛹和总化蛹期为每个物种的混合种群相比，其单一物种的控制）是更明显的混合培养物饲养在玻璃罐在实验室比轮胎在现场条件下。在实验室条件下，对Ae.埃及伊蚊与埃及伊蚊共同饲养。白纹藻属triseriatus，或两者，幼虫显著加速。相反，Ae. albopictus和Ae.与Ae.而雌鸟的平均翅长则比雌鸟的短。albopictus和Ae.混合培养中的三列虫比单种培养中的多。这些数据表明，种内竞争的影响大于种间竞争。充足的食物和较高的温度似乎促进了三种伊蚊在田间轮胎中的快速发育和较高的存活率。总的来说，Ae。三列虫幼虫发育所需时间较长，死亡率较高。埃及伊蚊白纹伊蚊Ae. albopictus的混合种群。albopictus和Ae.埃及伊蚊在广口瓶和食物丰富的轮胎中，达到第一、50和75%累积化蛹所需的时间与单一物种对照没有显著差异。我们的结论是，没有明确的位移发生在混合实验种群的Ae。埃及伊蚊白纹伊蚊
Interactions among the larvae ofAedes aegypti(L.),Ae. albopictus(Skuse), andAe. triseriatus(Say) were studied in trispecific and bispecific mixed populations under laboratory and field conditions. Competitive stress (as evidenced by the average time to first, 50, and 75% pupation and the total pupation periods for mixed populations of each species in comparison with their single species controls) was more pronounced in mixed cultures reared in glass jars in the laboratory than in tires under field conditions. In the laboratory, the larval development ofAe. aegyptireared together withAe. albopictusorAe. triseriatus,or both, larvae was accelerated significantly. Conversely, the time to pupation forAe. albopictusandAe. triseriatuswas delayed when reared withAe. aegypti.However, the average wing length of femaleAe. albopictusandAe. triseriatuswas greater in the mixed cultures than in single species cultures. These data indicated that the effect of intraspecific competition was greater than interspecific competition. Adequate food and higher temperature appeared to promote rapid development and higher survival of the immature stages of the threeAedesspecies in tires placed in the field. In general,Ae. triseriatuslarvae required a longer period for larval development and had greater larval mortality than eitherAe. aegyptiorAe. albopictus.In mixed populations ofAe. albopictusandAe. aegyptiin the jars and food-rich tires, the periods needed to attain first, 50, and 75% cumulative pupation were not significantly different than in single species controls. We conclude that no clear-cut displacement occurred in mixed experimental populations ofAe. aegyptiandAe. albopictus.
