Abstract

A pilot-release study was carried out with genetically-altered Culex tarsalis at an isolated area in Kern Co. California. The results indicated that males carrying sex-linked double heterozygous translocations could be mass-produced, could be transferred as pupae to the field and emerge from artificial ponds, and could survive in the field as immatures and adults. Mark-release-recapture studies provided estimates of the size of the native population and survival rates of native and released adults. The release did not affect the density of the native population nor was the translocation recovered from field-collected egg rafts. One known contributing factor to this outcome was that the ratio of the translocated to the native population was never adequate.
