Remating in Ceratitis capitata sterile males: implications in Sterile Insect Technique programs

Figure 2 Diagram of conditional remating frequencies. Each set of branches shows the male response (mated in grey and unmated in white) after each remating choice. Values are expressed as conditional relative frequency and represent the average of eleven replicates. Numbers in brackets represent the total number of males evaluated at indicated time. Hyphen indicates that the number of males of these experimental combinations was too low for values to be representative.

Figure 3. Relative abundance of sperm stored in female spermathecae after each mating. Each subfigure represents the temporal pattern of the sperm transferred by V8 sterile males with distinct remating behavior responses. Unmated: male did not copulate during that copulation time. Mating occasions: first mating (1st M), 24-hour remating (24-h R), 48-hour remating (48-h R), 4-day remating (4-d R) and 7-day remating (7-d R) tests. Values are the average of sperm recorded in at least 20 females. Vertical bars indicate SEs and distinct letters represent statistical differences (one-way analysis of variance P<0.05).
