| Popis: | A field experiment, conducted on St. Croix, Virgin Islands of the United States, has previously demonstrated the feasibility of using the sterile male technique for suppression of Stomoxys calcitrans (L.). However, use of this method has been hampered because both sexes inflict painful bites on several species of animals. This problem has been partially circumvented by development of a genetic method that allows preferential elimination of females. This genetic sexing system utilizes malathion susceptibility as a conditional lethal and a male-linked translocation, T(1;2)5 , to fix a dominant resistance allele in the male sex. A dominant malathion-resistance gene was found in a population from Nebraska. This gene, malR , was linked to the Y chromosome by radiation-induced to produce a strain composed of resistant males and susceptible females. Leakage of undesirable phenotypes occurred at a low, but manageable, level. |
