Genetics of the Encephalitis Vector, 'Culex tarsalis' for Possible Application in Integrated Control.
Abstract
The projects here reported 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 1978-79 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 14. Two additional mutants were isolated. Among the translocated strains that were given priorities for evaluation as release material are: 1 sex-linked, and 2 autosomal. The sex-linked is a multiple, involving all 3 chromosomes. The 2 autosomes are in the homozygous condition. The sex-linked multiple translocation strain was used for 2 pilot-release studies. Substantial progress was made in the preparation and mapping of salivary chromosomes. Chromosome-linkage group correlation was established for the species. Comparisons of reproductive behavior of laboratory and field-collected females were made. Mark-release-recapture studies were carried on throughout the spring and summer. The sterile-male method was developed for c. tarsalis. and A mass-production program successfully produced 180,000 males over a pre-determined period. (Author)
