Single and mixed species densities of adult Aedes albopictus and Culex quinquefasciatus were manipulated to determine if different combinations affected their egg laying preference or mortality rates. Oviposition was measured in environments that contained containers of different surface areas (small cups vs. larger bowls), and the number of eggs (Aedes) and egg rafts or larvae (Culex) deposited by each species was examined with respect to intra- and interspecific density treatment levels. Mixed species densities did not have an effect on survivorship, but single species densities did affect longevity, with higher densities leading to shorter life spans in Cx. quinquefasciatus: Cx. quinquefasciatus lived longer than Ae. albopictus overall. There was no significant effect of density combinations on oviposition patterns in either species, but Cx. quinquefasciatus laid more rafts in bowls compared with cups. There is little evidence of adult interactions between these species; however, future experimental work is necessary to more fully characterize the possible effects of adult interactions on these species.
对白纹伊蚊和致倦库蚊成虫的单物种及混合物种密度进行调控,以确定不同组合是否会影响它们的产卵偏好或死亡率。在包含不同表面积容器(小杯子与大碗)的环境中测量产卵情况,并针对种内和种间密度处理水平,检查每个物种产下的卵(白纹伊蚊)以及卵块或幼虫(致倦库蚊)数量。混合物种密度对存活率没有影响,但单物种密度确实会影响寿命,较高密度会导致致倦库蚊寿命缩短:总体而言,致倦库蚊的寿命比白纹伊蚊长。密度组合对这两个物种的产卵模式均无显著影响,但与杯子相比,致倦库蚊在碗中产下的卵块更多。几乎没有证据表明这些物种的成虫之间存在相互作用;然而,未来需要开展实验工作,以更全面地描述成虫相互作用对这些物种可能产生的影响。
