Fig. 2From: Genetic stability, genetic variation, and fitness performance of the genetic sexing Salaya1 strain for Bactrocera dorsalis, under long-term mass rearing conditionsThe relative sterility index (RSI) detected form the sterile male Salaya1 strain. RSI is estimated by the number of mating couples of the sterile males with wild females divided by the total number of mating couples [18]Back to article page
