A type of nuclear damage that is genetically nontransmissible can be induced prezygotically in the wasp Habrobracon. The damage is expressed as death very early in development. It is not a dominant lethal event because the damage is not expressed in the presence of a second nucleus. It is not a recessive lethal event because the damage cannot be found by genetic testing of the F/sub 1/ females. It is not cytoplasmic damage because the total damage when induced by uv radiation responds to photoreactivation, whereas cytoplasmic damage in Habrobracon embryos does not. It is inducible in Habrobracon by uv radiation, apparently also by nitrogen mustard, and to a limited extent by x radiation. The effect is that of a nuclear reactivation which seems to be independent in response from photoreactivation. (auth)
