1987년과 1992년의 6월부터 10월까지 전남 완도와 경기도 고양시에서 소를 흡혈한 중국얼룩날개모기 성충을 채집, 산란.사육하여 3~4령기 유충에 대한 각종 살충제 감수성 실험을 실시, 저항성 발달 정도를 조사하고 1981년도의 반치사농도(LC$_{50}$)값과 비교하였으며 malathion, fenitrothion 그리고 lindane을 1972년 Sintain strain에 비교하였다. Pyrethroids중 cyhalothrin의 LC$_{50}$은 0.011ppm으로 공시살충제중 가장 예민한 감수성을 보였으며 ethofenprox와 phenothrin은 각각 0.0403ppm과 0.0482ppm으로 나타나 대부분의 pyrethroids에 감수성을 보였다. 유기인제중 fenthion과 profenofos만이 각각 0.1276ppm과 0.2121ppm으로 감수성을 나타냈으며 fenthion은 1981년 0.056ppm에 비해 2.3배의 저항성이 발달하였고 완도 strai 에는 0.138ppm으로 거의 동일한 감수성을 나타냈다. 그러나 naled는 11.7배, pyridaphenthion 7.8배, chlorpyrifos 8.3배의 저항성이 발달하였으며 fenitrothion과 malathion은 1972년에 비해 각각 101.1배와 116.6배로 발달하였다. Cartap과 carbofuran 등 카바메이트제에도 고도의 저항성을 나타냈으며 특히 carbofuran은 72.1ppm으로 공시살충제중 최고의 저항성을 보였고, 유기염소제인 DDF와 lindane은 각각 192.1배와 4,1배의 저항성이 발달하였다. Bacillus thuringiensis israelensis에는 0.125에서 1.3883mg/1의 감수성을 보였다 보였다
Studies were performed on the susceptibility and/or resistnace to various insecticides including malathion, fenitrothion and lindane against 3∼4th instar stages of Anopheles sinensis larvae from laboratory cultured after originally collected from Wando, Chollanam do and Koyang city, Kyeonggi do during the period of June through October, 1987 and 1992, respectively. The data of them were compared with Koyang strain of data 1981 and Sintain strain data of 1972. The tested larvae showed the most susceptible to cyhalothrin with $LC_{50}$ of 0.011ppm followed by ethofenprox and phenothrin with 0.0403 and 0.0482ppm respectively, indicating a general susceptibility to most of the pyrethroids. In organophosphates, the mosquitoes were only susceptible to fenthion and profenofos with $LC_{50}$ of 0.1276 and 0.2121ppm, respectively. However, the resistance was developed as much 2∼3 folds to fenthion as that of 1981 in 0.056ppm even the similar level of susceptibility was shown with that of Wando strain of 0.138ppm. The development of resistance was noticed to naled, pyridaphenthion and chloropyrifos as much of 11.7, 7.8 and 8.7 folds, while to fenitrothion and malathion, the level of resistance was 101.1 and 116.6 folds in comparison with those of 1972, respectively. Among carbamates, the mosquito larvae showed higher development of resistance as to carbofuran 72.1ppm and cartap 7.58ppm, while DDT and lindane also showed higher development of resistance as much of 192.1 and 4.1 folds, respectively. They were susceptible showing in 0.125∼1.3883mg/1 to Bacillus thuringiensis israelensis.
