MUTANTS OF THE PARASITIC WASP DAHLBOMINUS FUSCIPENNIS (ZETT.) (HYMENOPTERA: EULOPHIDAE),
Abstract
The main phenotypic effects of 12 visible mutants are reported in the arrhenotokous wasp, Dahlbominus fuscipennis (Zett.) (Hymenoptera: Eulophidae). All but two of the mutations occurred among haploid males following irradiation of wild females, the others during pedigree breeding of irradiated stock. Eight of the mutations affected pigmentation of the eyes or body, three produced morphological abnormalities in the wings and antennae, and one reversed the sex ratio. All but the last one were controlled by recessive factors, each of which has been assigned a name and symbol. The sex reversing factor was dominant and sex-limited, being transmitted by females to their sons. Although tests for linkages between the mutations have not been completed, in initial crosses between four of the bright eye-colors and the wing mutations, segregation was independent indicating that these arose as separate mutations. An account is given of the life history of the species and a description of the adult and immature stages of the wild stock as a basis for comparison with the mutant lines. A simple method is given for rearing large numbers in the laboratory. (Author)
