dc.description.abstractThis study sought to establish the direct effects of varying temperatures on the growth and development of the two members of the domestic mosquito, Culex pipiens complex; Culex pipiens pallens Coquillett and Culex pipiens molestus Forskal. The methods used were similar to those used by [18]. The mosquitoes used were obtained from colonies reared at the Kosin University; south Korea, Insectary at a temperature and relative humidity regime of 27 ± 1 oC and 75 ± 5% RH, respectively and a 13:11 light and dark photoperiod. The effects were evaluated in terms of embryonation times, length of the larval and pupal stages, the survival rates and maximum longevity of the female. Varying temperatures were found to have effects on egg embryonation, the lengths of the pupal and larval periods and the survival and longevity of the female mosquitoes. The results showed that in lower temperatures embryonation took longer among the 20oC and 24oC the larval and pupal stages were longer and the female mosquitoes lived longer. In higher temperatures (28oC), embryonation was faster, the larval and pupal stages were shorter and the females did not live for as long as they did at 20oC and 24oC. There were no significant differences (p > 0.05) in egg embryonation times between the two subspecies, at the three temperatures used in the study. There were no significant differences in the larval period between the two subspecies between 24oC and 28oC. However, the length of the pupal period in the two subspecies differed significantly (p < 0.05), at the three experimental temperatures. The pupal period of Cx. Pipiens pallens averaged 5.5, 6.5 and 2.7 days while that of Cx. pipiens molestus averaged 6.4, 4.3 and 2.28 days at 20oC, 24oC and 28oC temperatures, respectively.
