| Abstract: | Genetic death in Luhong Chinese Tusser race happens at head pigmentation stage. The head and mouth parts of genetic death embryo have low ossification .Its segments are swollen. There are different deformation and degeneration in its abdominal leg. The number of its bristles decreases. The lengths of the bristles are one half or one third of normal ones. The newly hatched larvae do not do keburui, is incompletely exuviated larva. The front end of midgut is obviously thin. |
| Keywords: | genetic death Red Chinese Tusser morphology and anatomy |
