유기인체 살충제인 Pyraclofos에 저항성인 집파리를 profenofs로 7세대 도태시킨 P-Pro 계통을 이용하여 Pro-fenofos 저항성의 유전학적인 분석을 행하였다. Profenofos저항성은 불완전우성으로 나타났기 때문에 가시돌연변이로 각 염색체를 표식한 감수성 ac, ar, bwb, ye, snp 계통을 이용하여 male-backcross에의한 연쇄군분석을 한 결과, 이 계통의 profenofos 저항성의 우성유전자는 각 염색체에 고루 존재하지만 제 2 염색체와제 5염색체 상의 유전자에 크게 지배받으면 웅성결정인자 M은 제 3염색체와 관련이 있는 것으로 나타났다.

The profenofos-resistant P-Pro strain of house fly (Muscn domestica L.) was derived from the pyraclofos-resistant strain by selecting with profenofos for 7 generations. The resistance was shown to be incompletely dominant by the reciprocal crosses between the resistant and susceptible strains. Linkage group analysis for the dominant factor responsible for this resistance was carried out by the F, male-backcross method, using susceptible multi-chromosomal marker strain. The major factors for profenofos resistance were located on the second and the fifth chromosome and the other chromosomes had a little effect on the development of this resistance. The male determining factor (M) was linked to the third chromosome in this strain.
