Study on the Embryo Development of the Kusmi Strain of Kerria lacca

  • Received Date: 1995-07-12
  • In the light of the principles of insect embryo development,6 typical developing stages of this lac insect embryo may be divided as follows:lst stage-blastoderm formation; 2nd stage-germband formation,3rd stage-protopod;4th stage-polypod; 5th stage-olo-gopod; 6th stage-larva formation. To forecast the due time for broodlac collection,it’s necessary to observe the advancement of the embryo development, the volume of“yellow spots”(hatching cavities under lac encrustation) and in combination with the initial days of swarming. This is a way,which is not only practicable in cutting stick broodlac in situ but available for distribution and allocation to other regions far away.

Abstract: In the light of the principles of insect embryo development,6 typical developing stages of this lac insect embryo may be divided as follows:lst stage-blastoderm formation; 2nd stage-germband formation,3rd stage-protopod;4th stage-polypod; 5th stage-olo-gopod; 6th stage-larva formation. To forecast the due time for broodlac collection,it’s necessary to observe the advancement of the embryo development, the volume of“yellow spots”(hatching cavities under lac encrustation) and in combination with the initial days of swarming. This is a way,which is not only practicable in cutting stick broodlac in situ but available for distribution and allocation to other regions far away.
