What is Inheritance of beta-cypermethrin resistance in the housefly Musca domestica (Diptera: Muscidae) about?

## Abstract BACKGROUND: Beta‐cypermethrin, a synthetic pyrethroid insecticide, was applied frequently in the control of health pests including houseflies, __Musca domestica__ L., in China. However, different levels of resistance to beta‐cypermethrin were monitored in field strains of houseflies. A strain of __M. domestica__, 4420‐fold resistant to beta‐cypermethrin after continuous 25 generations of selection, was used in this paper to determine the mode of inheritance of pyrethroid resistance. RESULTS: The estimated realized heritability (__h__^2^) of beta‐cypermethrin resistance was 0.30 in this resistant strain. Results of bioassays showed no significant difference in values of LD~50~ and slope of log dose‐probit lines between reciprocal progenies F~1~ and F′~1~, and yielded values of − 0.10 (F~1~) and − 0.11 (F′~1~) for the degree of dominance (__D__). Chi‐square analysis from responses of self‐bred and backcross progenies (F~2~, BC~1~ and BC~2~ respectively) indicated that the null hypothesis, a single gene responsible for resistance, was accepted. The minimum number of independent segregation genes was 0.93 for F~1~ by Lande's method. CONCLUSION: It was concluded that beta‐cy
