Dieldrin resistance in Lucilia cuprina (the australian sheep blowfly): chance, selection and response.

摘要: Discrete-generation population cages of Lucilia cuprina were initiated with dieldrin-resistant allele (Rdl) frequencies 1 or 5% and maintained for 17 generations on media concentrations dieldrin in the range 0–0.006% (w/v). The probability initial establishment Rdl a was consistently greater at frequency dependent concentration medium both starting frequencies. Once resistant established responses to selection concentration-dependent. It concluded that absence susceptible selectively favoured, 0.00005% (w/v) random genetic drift influenced changes above this selective advantage. Fixation occurred higher concentrations. influence response during evolution insecticide resistance is discussed.
