摘要
采用Ｃｏ６０对中华紫胶虫、紫胶蚧两种紫胶虫的不同虫态进行了辐射试验，结果表明，在中华紫胶虫卵胚发育２～３期以１０００ｒａｄ辐射可以产生子代，在紫胶蚧卵胚发育５～６期以１１０００ｒａｄ辐射，偶然得到子代。对辐射子代的怀卵量、性比、固虫密度、泌胶量等进行了观察。紫胶蚧子代的怀卵量、泌胶量与对照相似，有效生殖力和雌虫性比高于对照，固虫密度低于对照；中华紫胶虫子代固虫密度、雌虫性比高于对照，怀卵量、泌胶量正常。
Two kinds of lac insect ( Kerria chinensis,K.lacca ) were radiated in this radiation experiment. The different stage of lac insect (larva,adult) are radiated by several dosages of Co 60. Tests showed that lac insects in the second stage are all dead after radiation of 500～2 000 rad,female insect of K.chinensis with pregnancy egg time 2～3 stage radiated by 1000 rad can produce new generation. female insect of K. lacca with pregnancy egg time 5～6 stage radiated by 11 000 rad occasionally produce new generation. The egg amount and amount of secreting lac are similar to those of the normal,effective production and sex ratio are higher than those of the normal,group density on branch is lower than the normal in the generation of K. lacca after radiation. The sex ratio of the female,group density on branch are higher than those of the normal,egg amount and amount of secreting lac are normal in the generation of K. chinensis after radiation.
