Comparison of fitness variables between male and female vectors. a Mean number of V⁻ females that copulated with single V⁺ or V⁻ male in 24, 48, or 72 h. b Effects of RGDV infection on the longevity of male and female adult R. dorsalis. c Sex ratio of offspring produced by parental insects from different mating combinations (V⁻♀ × V⁻♂, V⁺♀ × V⁻♂, V⁻♀ × V⁺♂ or V⁺♀ × V⁺♂). d Progeny egg number, size and hatching rate of female adults from different mating combinations (V⁻♀ × V⁻♂, V⁺♀ × V⁻♂, V⁻♀ × V⁺♂ or V⁺♀ × V⁺♂). Data are presented as mean ± SE of three independent experiments of four mating combinations. The significance of any differences was tested using Student’s t test a–b or Tukey’s HSD test c–d. ^*P < 0.05. Different letters after means in the same column a or line (d) indicate a significant difference at P = 0.05, and the means do not differ significantly if they are indicated with the same letter. V⁺, viruliferous. V⁻, nonviruliferous
