Abstract

The mode of inheritance of resistance to parathion, fenitrothion, fenthion, chlorpyr fosmethyl, and parathion-methyl was studied in a strain of C. tarsalis. Resistance in the F(1) hybrid was partially dominant. Backcross experiments indicated that resistance is derived from more than one gene. This conclusion was confirmed by repeated backcrosses of the F(1) to the susceptible strain and selection of the backcross progeny with a discriminating dosage of parathion-methyl.

摘要

在一种塔氏库蠓品系中研究了对硫磷、杀螟硫磷、倍硫磷、甲基毒死蜱和甲基对硫磷的抗性遗传模式。F(1)杂种中的抗性呈部分显性。回交实验表明,抗性由多个基因决定。通过将F(1)与敏感品系反复回交,并使用鉴别剂量的甲基对硫磷对回交后代进行选择,这一结论得到了证实。
