The interpretation of surveys of DDT-resistance in body-lice is handicapped by the fact that the genetics of this form of resistance have not been studied. This paper reports on a preliminary investigation on normal and resistant strains of lice, F(1) and F(2) hybrids of a mass cross and F(1) x R hybrids exposed to DDT dust and DDT-impregnated paper of various concentrations. The results were consistent with inheritance by a single gene pair (or possibly a small number of genes). The F(1) hybrids were intermediate in tolerance but were all killed by 5% DDT dust. This confirms a suggestion that 5% DDT dust would be suitable for testing for incipient resistance.
由于尚未对这种抗药性的遗传学进行研究,因此对体虱抗滴滴涕调查结果的解读受到了阻碍。本文报告了对正常和抗性虱株、大量杂交产生的F(1)和F(2)杂种以及暴露于不同浓度滴滴涕粉尘和滴滴涕浸渍纸的F(1)×R杂种进行的初步调查。结果与单基因对(或可能少数几个基因)遗传一致。F(1)杂种在耐受性上处于中间水平,但均被5%滴滴涕粉尘杀死。这证实了一个观点,即5%滴滴涕粉尘适合用于检测初期抗药性。
