Field Releases with Adults and Pupae of Toxorhynchites Rutilus Rutilus (Diptera: Culicidae)

Abstract
Laboratory-reared adults and pupae of Toxorhynchites rutilus rutilus were released in a 9-square-block (7.5-ha) residential area and in a ca. 60-ha pine forest during 1980 and 1981 to compare oviposition rate, length of ovipositional period, and daily adult survival. Of these criteria, only female fecundity differed between 2 release methods; females from the pupal release laid ca. 50% more eggs than those released as adults. Survival rates and ovipositional periods for the 2 groups were similar.
