In this paper was given the results of observation on the seasonal change of the fly fauna in Sungdong-Ku(District), Seoul City. during a period from May to November 1963. The collections of flies were done indoors (kitchen)and outdoors(yard) using a glass trap for each. Boiled rice and peaces of bread were used as bait. In order to collect more dat, the fly-counting with Scudder's fly-grill was also made outdoors. Five dongs(Subdistrict) in Sungdong-Ku were selected for the study. For convenience each Dong was marked as follows: Dong Ⅰ: Residential area of Sindang-Dong. Dong Ⅱ: Market(fishmonger and butcher's) area in sindang-Dong. Dong Ⅲ: Vegetable farm area in Duksom. Dong Ⅳ: Residential area of Kumho-Dong. Dong Ⅴ: Slum area of Hungin-Dong One house was selected from each dong for observation. During the period of study, the collections and the fly-countings were carried out at the selected house from 2:00 to 3:00 p.m. at a week interval. The total number of flies collected were 44,254. Those were classified into four families and seven genera; of these the largest numbre was Calliphoridae(24,628 ir 55.7%) and the second in number was Muscidae(12,343 or 27.9%) Those collected in the market area of Sin-dang-Dong was the highest(17,903 flies) and the lowest was in Sindang-Dong(residential area). All genera were caught throughout the period and were most abundant during the months of September and October. the driest season in Seoul Comparing the above data with the meteorological data of Seoul in 1963, there was the negative correlation between the precipitation and the population density of flies.

The problem of controlling fly-borne diseases still constitutes one of the serious problems yet to be solved. Furthermore, the marked development of fly resistance to insecticides as reported here and elsewhere has added another -difficulty to the control of disease. With regard to the resistance of the Korean housefly, Wheeler et al first observed, with a topographical method, the susceptibility of the Korean houseflies collected in Seoul to p,p'- DDT, Y- BHC, Dieldrin and Malathion during the period, 1955-56, and found that the Seoul strain was more susceptible as compared with strains in Japan where a high resistance was shown. My observation with a 24 hour mortality on the fly-resistance to p,p'-DDT in 19587 indicated that the Seoul strain has a high degree of resistance that corresponds to fly colony resistaa. No. 2 at the Orlando laboratory, Fla., U.S.A. If the Korean flies have thus developed resistance, tl;,, -,%hcther or not these insecticides are to be contin. uously used becomes a serious problem of rcconsfd_ oration. If the insecticides presently used can not be relied upon for fly control, immediate steps would be necessary to find another substitutes or a new method' of controlling vectors. Therefore, the more precise knowledge of the present status of fly-resistance to the insecticides would be of a great value in establishing effective countermeasures. From this standpoint, I attempted to study more in detail the toxicological effects of insecticides currently used in Korea, applying the biometric analyses of the Bliss probit method on the experimental data. Next, pertaining to the sexual difference of the flies to the resistance of insecticides, it is generally understood that the males are more susceptible than the females. Without any consideration of the sex ratio, it is difficult to arrive at a clearcut dosage or time response relation from experiments with insects. Therefore, the elucidation of sexual influence on the susceptibility of the flies is also attempted in this experiment.
