尽管经过了近一个世纪的努力，疟疾寄生虫是否会杀死蚊子媒介的问题仍然悬而未决。一些对感染和未感染蚊子寿命的直接比较发现了疟疾导致的死亡，而另一些则没有。在这里，我们使用荟萃分析来表明，总的来说，疟疾寄生虫确实降低了蚊子的存活率。然而，在非自然病媒-寄生虫组合和持续时间较长的研究中，更有可能检测到死亡影响。除非对这些因素进行系统的调查，否则不可能得出明确的结论。
Despite almost a century of effort, the question of whether malaria parasites kill their mosquito vectors remains open. Some direct comparisons of the longevity of infected and uninfected mosquitoes have found malaria-induced mortality, whereas others have not. Here, we use meta-analysis to show that, overall, malaria parasites do reduce mosquito survival. However, mortality effects are more likely to be detected in unnatural vector-parasite combinations and in studies of longer duration. Until these factors are systematically investigated, no firm generalities are possible.
