一个早期的白蚁群体最初是一个双亲家庭单位。第一批工蜂的出现开启了一个群体从双亲养育到异亲代养育的转变。在这个转变过程中，孔雀鸟（Kolbe）国王和王后所携带的原生动物数量是动态的。在optotermes gestroi（Wasmann）中，在群体建立后150天完成向异体亲代照料的过渡。在本研究中，我们量化了c的原生动物丰度。在双亲代到异亲代养育过渡的10个时间点（群体建立后0-400天）中，台湾白蚁和白蚁的王和王。原生动物丰富的c。gestroiandC。在双亲抚育期间，雄蝶和皇后在第35天或第60天达到高峰，然后在接下来的研究中逐渐减少。到第400天，国王和女王的原生动物丰度与未交配动物的丰度相似或更少。BothC。gestroiandC。在第150天的时候，尽管已经完成了向异体亲代照料的过渡，但台湾雄蚁和蚁后仍然会孕育原生动物。在第250天和第400天。福尔摩沙，第400天c部队。Gestroi，国王的原生动物数量比女王的要多。这些结果表明，异体亲代照料可以在蜂群原生动物丧失之前在蜂群中建立起来，并且在蜂群发育初期，蜂王比蜂王更早失去原生动物。
An incipient termite colony initially functions as a biparental family unit. The emergence of the first workers initiates the transition from biparental to alloparental care within a colony. During this transition, the number of protozoa harbored byReticulitermes speratus(Kolbe) kings and queens is dynamic. InCoptotermes gestroi(Wasmann), the transition to alloparental care is completed by 150 days after colony foundation. In the present study, we quantified the protozoan abundance ofC. gestroiandCoptotermes formosanusShiraki kings and queens at ten time points during the transition from biparental to alloparental care (0–400 days post colony foundation). The protozoan abundance ofC. gestroiandC. formosanuskings and queens peaked on either day 35 or 60 during the biparental care period, and then progressively decreased during the remainder of the study. By day 400 the protozoan abundance of kings and queens was either similar to or less than the abundance observed within unmated dealates. BothC. gestroiandC. formosanuskings and queens still harbored protozoa at day 150 even though the transition to alloparental care was completed by this time. On days 250 and 400 forC. formosanus, and on day 400 forC. gestroi, the protozoan abundance of kings was greater than the abundance of queens. These results indicate that alloparental care can become set within a colony prior to the loss of protozoa within the royal pair, and that queens lose their protozoa earlier than kings during incipient colony development.
