The breeding of taeniorhynchus (Subgenus mansonioides) mosquitoes in the laboratory

Three species of Taeniorhynchus (subgenus Mansonioides), (T. africanus, T. annuliferus and T. uniformis), have been maintained in the laboratory for more than 1 year, and for more than 12 generations. The life history is briefly described and illustrated by photographs. The adult mosquitoes mate and feed readily in captivity. The routine method of keeping the adult mosquitoes, and a technique for obtaining eggs, are described. Experiments are reported in which various larval culture methods were tested. A simplified technique, suitable for rearing these mosquitoes away from the tropics, is described in which the larval environment is diluted dog biscuit, or guinea-pig dung, infusion, stabilized by a turf, and maintained by the addition periodically of biscuit or yeast. Living plants have been replaced by brown paper as an air source for the larvae. The greatest mortality in the cultures occurs soon after the larvae hatch, with a further appreciable loss at pupation.
