Genetics of the Encephalitis Vector, Culex tarsalis, for Possible Application in Integrated Control.
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.
