Competitiveness of sterile male boll weevils, Anthonomus grandis grandis Boheman, released in the boll weevil eradication trial averaged 11.7%. Sterile males were significantly more competitive against males of a native strain when laboratory strain virgin females rather than native-strain virgins were released (20.0 vs. 6.2%). Laboratory quality control tests of mortality and mating ability indicated that the sterile males were inferior to those used in previous years. Treated females laid fewer than five eggs each. No progeny developed from treated female × normal male crosses. Of the eggs laid by treated females, 89% were identifiable by traces of dye found on them.
