The Radiation Experiment for Lac Insects

  • Received Date: 1997-09-15
  • 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.

Abstract: 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.
