花胸散白蚁多型行为的初步分析

POLYETHISM IN RETICULITERMES FUKIENENSIS:A PRELIMINARY STUDY

该文在花胸散白蚁ReticulitermesfukienensisLight的侦察行为和取食行为方面进行了比较详细的探讨，同时还分析了其消化系统发育与取食行为变化之间的相互关系。实验结果表明年龄是影响花胸散白蚁多型行为的一个比较重要的因素。而且发现幼蚁和工蚁的消化系统发育是与其取食行为相一致的，特别是后肠囊从幼蚁的细条消化道发育为成年工蚁的膨大囊袋这一过程是花胸散白蚁群体中存在着取食多型行为的强有力的证据。

This paper deals with the polyethism in Reticulitermes fukienensis Light.Experiment showed that the older workers undertake the scouting behavior even when soldiers are absent, and foraging polyethism exists inside the termite colonies. After observing the gut contents of the larvae and workers it was found there is no semi-solid dark brown materials inside the larva's gut parts and a large amount of semi-solid dark brown materials inside the gut parts of workers, it can be inferred that larvae feed themselves on liquid foods through trophallaxis and sucking and workers feed themselves on fiber materials. On the aspect of the gut structure for larvae and workers, their paunches have undergone developmental change, from slender tubular gut to expanding sac.Age seems to play a role in the polyethism in R. fukienensis.
