Abstract

A method of marking adult Culex quinquefasciatus by feeding the larvae commercial hog chow dyed with methylene blue, Giemsa, and crystal violet was evaluated under laboratory conditions. Of 243 mosquitoes fed the dyed food, 230 had visible marks (94.6%). The dyed food increased the egg–adult development time from 11.4 to 12.1 d. After 9 d, 82.5% of adult mosquitoes dyed as larvae could be identified, and remained detectable for up to 15 d, their maximum laboratory life.
