  1. N = number of untreated males; S = number of (semi) sterile males; Hn = egg hatch of the cross fertile Dongola ♂x Dongola ♀; Hs = egg hatch from the cross (semi) sterile GSS ♂ x Dongola ♀; Ho = observed hatch rate; IS = induced sterility; C = competitiveness value; CV = coefficient of variance; CL = confidence limits. Egg hatch is expressed as a rate.
