The factors favouring the cessation of reproduction in X. conformis are laid in the preimaginal state. The drop in temperature during the formation of imago at the pupal stage is a signal for the cessation of reproduction. Imagos hatched at a temperature lower than that of developmental conditions of preimaginal stages do not start reproduction and enter facultative imaginal diapause state. With further decrease in temperature the state of fleas intensifies. With the rise of temperature fleas come out of diapause. In autumn coming out of diapause begins at a temperature higher than 20 degrees, on the 8th--9th day. The lower air temperature the more rapid is coming out of diapause, at a rise of temperature of 3 to 5 degrees.
有利于 conformis 蚤停止繁殖的因素在其成虫前期就已奠定。蛹期成虫形成过程中温度的下降是繁殖停止的信号。在低于成虫前期发育条件温度下孵化出的成虫不会开始繁殖,而是进入兼性成虫滞育状态。随着温度进一步降低,跳蚤的这种状态会加剧。随着温度升高,跳蚤会从滞育状态中出来。在秋季,当温度高于20摄氏度时,跳蚤在第8至9天开始从滞育状态中出来。气温越低,跳蚤从滞育状态中出来的速度就越快,温度每升高3至5摄氏度就会加快这一过程。
