Abstract

The mode of inheritance of dieldrin resistance was studied in Anopheles farauti No. 1 and A. farauti No. 2. In both these species a susceptible strain was crossed with a resistant strain and F1 individuals backcrossed to the susceptible parental strain. After exposure to 0-4% dieldrin for one hour the survivors were again backcrossed to the susceptible. After successive backcrosses it was found that in both species dieldrin resistance was determinded by a single, semi-dominant gene which was not sex-linked.

摘要

在1号费氏按蚊和2号费氏按蚊中研究了狄氏剂抗性的遗传模式。在这两个物种中，均将一个敏感品系与一个抗性品系杂交，然后将F1代个体与敏感亲本品系回交。在接触0-4%狄氏剂1小时后，将存活者再次与敏感品系回交。经过连续回交后发现，在这两个物种中，狄氏剂抗性均由一个非性连锁的单基因半显性基因决定。
