Although some eggs ((3n×2n)eggs) oviposited by a triploid female crossed with a normal male were fertilized, none of the fertilized eggs hatched out. However a few parthenogenetic eggs from triploid oocytes were able to hatch. When the inseminated (3n×2n) eggs were treated immediately after oviposition with hot water, a few treated eggs hatched out.<br>A few eggs produced by a triploid female showed a normal function, and death of the (3n×2n) egg was attributed embryonic factors.<br>The color of the eggs ovipolited by a triploid female(+re/+re/re) and (+/re/re) crossed with a diploid male (re/re) segreted with a ratio of 5 normal pigmented eggs to 1 red egg. Based on the cytological observation, the embryos in the (3n×2n)eggs were heteroploid (about 70 chromosomes)., the histological observation of the embryogenesis of (3n×2n) eggs, revealed of the presence of severe abnormalities and the, eggs eventuelly died during subsequent embryonic development.<br>On the basis of these results, we suggested that death by abnormal embryogensis in the (3n×2n) eggs may be ascribed to heteroploidy.
