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 Culex 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 1976-77 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 7. Among the translocation strains that show promise are: 9 sex-linked, 3 autosomal. Two sex-linked are multiples, involving all 3 chromosomes. Two autosomes are in homozygous condition. A sex-linked multiple translocation strain was studied for competitiveness in laboratory and large-outdoor cages. Computer models were used to determine number of males released this spring in pilot study. A mass-production program successfully produced 100,000 males over a predetermined time period. In vector competence studies, a refractory strain was successfully selected. Genetic studies determined that susceptibility to WEE virus was dominant and controlled by more than 1 gene.
