Inheritance of phosphine resistance in Tribolium castaneum (Coleoptera : Tenebrionidae)
Journal of Economic Entomology 92 (1), 17-20
Abstract: The genetics of phosphine resistance was studied in a resistant strain of the red flour beetle, Tribolium castaneum (Herbst), developed from field collections in Queensland, Australia. A program of inbreeding and selection was maintained for 5 generations to promote homozygosity in this strain and a laboratory-susceptible strain. The strain was then 12.7 times resistant in the Food and Agriculture Organization of the United Nations test on adult insects. Data from the testing of F₁ progeny from the reciprocal crosses (Rfemale × Smale and Sfemale × Rmale) indicated that resistance was autosomal and semidominant with a degree of dominance -0.47 (-0.51, -0.44). Modified chi-square analysis and contingency analysis of data from the response of test crosses of F₁ progeny to both the susceptible and resistant strains and on F₂ progeny were highly significant. Low-level resistance typical of Australian populations of T. castaneum is conferred by 1 gene.
