Values given as percentages of adult females eclosing with at least two missing or defective bristles on the most methoprene-sensitive sternite 7. Nontransformant siblings of each genotype, recognized by white eyes, were completely resistant as expected and are presented as the w v Met3 row for simplicity. Fifty adult females of each genotype were evaluated. Transformant and nontransformant adult responses to each concentration of methoprene were compared (Fisher’s exact test) and were significantly different (P < 0.001, designated by ∗) for the two highest methoprene concentrations. Responses are also shown for v adult females (having two Met+ gene doses) for comparison. NS, nonsurvival to adult stage.
