Genetics of the Encephalitis Vector, 'Culex Tarsalis' for Possible Application in Integrated Control.
Abstract
A resume of progress for the year 1977-78 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 8. Three new mutants were isolated; Among the translocation strains that show promise are: 2 sex-linked, 3 autosomal. Two sex-linked are multiples, involving all chromosomes. Two autosomes are in homozygous condition; A sex-linked multiple translocation strain was studied for competitiveness in laboratory and large-outdoor cages; A new method for isolating heterozygotes and homozygotes was devised; A pilot release study was carried out at isolated sites in Kern County; Population dynamics studies on native and release immatures were completed; Mark-release-recapture studies were carried on throughout the spring and summer; Computer models were used to determine number of males to be released this spring in 2nd pilot study; and 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.
