High levels (about 4,000-fold) of resistance to dieldrin were isolated by screening field-collected populations of Drosophila melanogaster (Meigen). The resistance was made homozygous following 2-4 generations of selection. A single, major gene mapping to the left arm of chromosome III was solely responsible for resistance. The implications of the recovery of resistant mutants from field populations of D. melanogaster are discussed.
通过筛选从野外采集的黑腹果蝇（Meigen）种群，分离出了对狄氏剂具有高水平（约4000倍）抗性的个体。经过2至4代的选择后，使这种抗性纯合。一个位于第三号染色体左臂上的单一主基因是产生抗性的唯一原因。本文讨论了从黑腹果蝇野外种群中获得抗性突变体的意义。
