Abstract The sterile insect technique is gaining an increasing role in the control of Mediterranean fruit fly, Ceratitis capitata (Wiedemann), populations. In the current study, we examine how post-teneral nutrition during the first 4–8 d after adult emergence affects performance and copulatory success in leks of mass-reared sterile (TSL strain) males. We found that protein and sugar fed males were significantly more likely to emit pheromone (call) in leks, and more likely to copulate, than males fed only sugar. Sterile males, who had access to water and apples after 4 d of feeding on protein and sugar, or sugar alone, were significantly more likely to copulate than their starved competitors who had access to water alone. However, after 24 h of starvation, 4-d protein-fed males suffered a higher mortality than sugar-fed males. More work is necessary to determine the optimal protein formulation that will maintain a balance between hastened mortality and increased sexual competitiveness of sterile males.

MEDFLY AREAWIDE STERILE INSECT TECHNIQUE PROGRAMMES FOR PREVENTION, SUPPRESSION OR ERADICATION: THE IMPORTANCE OF MATING BEHAVIOR STUDIES (2002, methodology): “A good knowledge of sexual selection mechanisms is required for the successful implementation of the sterile insect technique (SIT) developed by Knipling (1955) to control insect pest populations (Burk & Calkins 1983). Sexually selected traits are usually a good reflection of male fitness and are th”
Improving sterile male performance in support of programmes integrating the sterile insect technique against fruit flies (2013, background): “…hydrolysate to males in the days following emergence can enhance male reproductive success, although the optimal dosage and form of presentation in an operational context still need to be established (Papadopoulos et al. 1998; Kaspi and Yuval 2000; Aluja et al. 2001; Pérez-Staples et al. 2007).”
Potential for pre‐release diet supplements to increase the sexual performance and longevity of male Queensland fruit flies (2008, methodology): “capitata , which exhibit greatest mating propensity at two peak ages of 4 and 11 days with lower values between these times and at greater ages ( Liedo et al. , 2002 ). Access to yeast hydrolysate for a brief period after emerging also reduced mating latency; males receiving yeast hydrolysate tended”
EFFECTS OF POST-TENERAL NUTRITION ON REPRODUCTIVE SUCCESS OF MALE MEDITERRANEAN FRUIT FLIES (DIPTERA: TEPHRITIDAE) (2002, background): “However, we also found that after 24 hours of starvation, four day old protein-fed males suffered higher mortality than sugar-fed males (Kaspi & Yuval 2000).”
Post‐teneral protein feeding enhances sexual performance of Queensland fruit flies (2007, background): “Whether released flies reliably acquire adequate nutrition, and whether prerelease provisioning of protein can improve performance, remain the topics of ongoing debate ( Kaspi & Yuval, 2000; Aluja et al. , 2001b; Shelly et al. , 2002; Shelly & Kennelly, 2003; Maor et al. , 2004 ).”
INFLUENCE OF MALE DIET ON MALE MATING SUCCESS AND LONGEVITY AND FEMALE REMATING IN THE MEDITERRANEAN FRUIT FLY (DIPTERA: TEPHRITIDAE) UNDER LABORATORY CONDITIONS (2002, methodology): “Following 24 h of starvation on the fifth day of life, mass-reared males fed a protein-containing diet for the preceding 4 d were far more likely to die than were males fed sugar only during the first 4 d of life (Kaspi & Yuval 2000).”
