The effects of various ecological factors, such as the probability of finding mates and hosts and of successfully obtaining a blood meal, on the mating and feeding strategies of domestic female anopheline mosquitoes was investigated using theoretical models. The models calculated the mean fitness of 1,000 nonblood-fed, anautogenous, virgin anophelines. One model simulated females that always mate before blood feeding, whereas another simulated females that are able to feed opportunistically if a host was detected before they mated. The models demonstrated highest fitness for mosquitoes capable of opportunistic feeding under nearly all simulated conditions. This advantage increased as the probability of finding hosts and mates decreased as a function of host and mate availability.
利用理论模型研究了各种生态因素,如找到配偶和宿主的概率以及成功获取血餐的概率,对家栖雌性按蚊交配和取食策略的影响。这些模型计算了1000只未吸血、非自育、处女按蚊的平均适合度。一个模型模拟总是在吸血前交配的雌蚊,而另一个模型模拟如果在交配前检测到宿主就能机会性取食的雌蚊。模型表明,在几乎所有模拟条件下,能够机会性取食的蚊子具有最高的适合度。随着找到宿主和配偶的概率因宿主和配偶可利用性的函数关系而降低,这种优势会增加。
