Abstract : The projects here reported represent part of an overall program designed to change C. tarsalis genetically to inhibit its propagation in nature, and to render it less effective as a vector of disease. A resume of progress for the year 1979-80 is as follows: the number of maintained strains for genetic studies was increased; multiple-marker strains for genetic studies and identification of translocations increased to 17. An additional mutant was isolated; among the translocated strains that were given priorities for evaluation as release material are 3 autosomal homozygotes and a 'pseudohomozygote' constructed from 2 of these; a field pilot-release study using sterilized males was carried out; several experiments compared reproductive behavior of wild type and laboratory-reared samples of Cx. tarsalis; comparative studies evaluated longevity, mating behavior, and competitiveness of sterilized males in large outdoor cages; progress was made in mapping the salivary-gland chromosomes; mark-release-recapture studies were carried on; and quality control measures.
