摘要专性和永久性社会寄生虫Polistes atrimandibularis侵入的Polistes biglumis bimaculatus的菌落周期不同于同一物种的正常菌落，这是由于存在的inquiline的影响。在有寄生虫的巢中，寄主的消失比在无寄生虫的巢中要快，而且P. B.双斑藻的出现既有时间上的限制，又有数量上的减少。在宿主羽化期结束后的短暂时间间隔后，寄生虫后代开始出现在入侵的菌落中，并继续羽化，直到季节结束。在被寄生的菌落中，P. B.与未被寄生的菌落相比，双斑拟步行虫的羽化率减少了一半，而羽化个体的总数（宿主加上寄生虫育雏）大于在正常菌落中观察到的总数（仅P. B. bimaculatus brood）。在寄生巢的群体周期和损失的变化进行了讨论。
Abstract The cycle of colonies of Polistes biglumis bimaculatus invaded by the obligate and permanent social parasite Polistes atrimandibularis differs from that of normal colonies of the same species as an effect of the presence of the inquiline. In parasitized nests the host foundresses disappear sooner than they do from non parasitized ones and P. b. bimaculatus emergences are both limited in time and reduced in number. After a brief temporal gap from the end of the host emergence period parasite offspring begin to appear in invaded colonies and continue to emerge until the end of the season. In parasitized colonies the number of P. b. bimaculatus emergences is reduced by half with respect to non‐parasitized colonies, while the total number of emerged individuals (host plus parasite brood) is greater than that observed in normal colonies (only P. b. bimaculatus brood). Changes in colony cycle and loss in host brood production in parasitized nests are discussed.
