黑胸散白蚁补充生殖蚁群体的发展与发育规律

从黑胸散白蚁Reticulitermes chinensis幼年群体或成熟群体中，分离出部分工、兵蚁个体，待培养出补充生殖蚁并开始产卵繁殖后，转移到大容器内饲养，观察了由补充生殖蚁控制的群体的发展与发育。 结果表明：分离群体在产生补充生殖蚁的过程中，群内个体数量有较大变动，其变动保存串约为61.5%；补充生殖蚁群体的发展较快，其个体数是在变动保存下来的基础上，经过一个恢复期后的发展；补充生殖蚁群体的发育较早，是伴随着群体的发展而发育；在实验条件下，由100一300头个体组建的群体，在产生的补充生殖蚁开始产卵后2-3年就可发育，进入分化出长翅成虫的成熟年龄，野外的自然群体，因群内个体多，不会因生殖蚁的更替而扰乱群体的发展和发育进程，更不会中断一年一度的分飞活动；在补充生殖蚁群体中，能再次产生补充生殖蚁，再生补充生殖蚁的品级可出现翅芽型补充生殖蚁。

THE COLONY DEVELOPMENT AND GROWTH BY SUBSTITUTEREPRODUCTIVES OF RETICULITERME CHINENSIS

e separated groups of worker and soldier castes from mature or immaturecolonies of Reticulitermes chinensis and transferred them into big vessels after substitute reproductives occurred and laid eggs; then observed the development androwth of colonies regulated by substitute reproductives. The results showed that thenumbers of individuals in the separated colonies underwent great fluctuation duringthe substitute repreductive development, and the survival rate was about 61--5 %.The substitute reproductive colonies would then develop faster and the numbers increased after a period of recovery on the basis of better survivorship. The substitutereproductive colony developed earlier, and it developed as the development of normal colonies. In experimental conditions, a colony of 100 to 300 individuals candifferentiate into winged adults in mature age in 2 to 3 years after the substitutereproductive lays eggs. In the field, the development and growth of a natural colony will not be disturbed by the replacement of reproductives because of the largenumber of individuals, and the annual flying activity will not stop either. The substitue reproductive colony can produce substitute reproductive once more, and thenthere may appear Substitute reproductive in wing--pad form.
