Chromosomal translocations are of importance in genetic control of insect pests. Translocation males have certain advantages over sterile males as regards mating vigor. The presence of good quality salivary gland chromosomes in Anopheles albimanus facilitated the detection of radiation-induced chromosomal translocations and location of the break-points in precise regions of the salivary chromosomes. Translocations involving all three chromosomes have been isolated and studied. Of particular interest have been the Y-autosome translocations because of the prospects of using such translocations in genetic control of this important vector species.
