Abstract


The routine entomological investigations were carried out in the areas of Kaejeon-Myon, OkkuGun, Cholla Pukdo province in 1964 and Sinchang-Myon, Asan Gun, Chungchong Namdo province in 1965, for the better understanding of the behavior of the anpheline mosquitoes especially of the population density , resting , feedign, and breeding habits. The results are as follows : 1. During the investigation , three species of anopheline mosquitoes were recorded ; Anopheles sinensis Wiedmann 1825, A, sineroides Yamada 1935, and A. yatsushiroensis Miyazaki 1951. A . yatsushiroensis Myiyasaki 1951, so far only recorded in Japan, was recorded for the first time in Korea in 1964 ; the site was Kaejong Myon, Okku Gun, Cholla Pukdo province. 2. Anopheles mosquitoes begin to appear from the middle of April and disappear in October. The date of mosquitoes collected by resting place collection in cow shed are three weeks ahead to the night time cow biting collection. 3. Resting places of anopheline mosquitoes are mainly in cow shed and outdoors which provides high humidity and shadow. 4. The population density of a. sinensis sows a peak in late June and early July in cow shed and by cow biting collection respectively, and another small peak in late August and early September. 5, . the biting activity at night is throughout the night from dusk to dawn, sharply decreasing just before dawn. The peak period was different in each months, 2100-2200 hours in June, 2300-2400 in July , 0300-0400 in August , and 2300-2400 in September. 6. The minimum temperature required for the mosquito's biting activity is 15℃ and the optimum is between 24-25℃ : over 25℃ the activity is decreased. 7.A , sinensis appeared to be zoophilic in Sinchang area but 13 times anthrophophilic in Kaejong area than the former. 8. the light attraction of a. sinensis is significantly low in middle June and early August. The parous rate of A. sinensis caught by cow biting collection appeared higher after midnight (2400-0300 hours) with no relation to the peak period of biting activity by month.
