“…While we found that protein-deprivation did not inhibit male reproductive competency over 24 h, the addition of protein to carbohydrate diet significantly enhanced male survivorship, which we believe could affect lifetime reproductive success (Figure 4). Maximum survivorship and median life expectancy of males provided with a mixture of carbohydrate and protein in our study was considerably longer (91 and 38 days, respectively) than previous records of maximum longevity for males maintained on similar diet in the laboratory or in field cages [41-70 days, (Allen & Askew, 1970;Vernon & Borden, 1979) and ca. 33 days (Perron & Lafrance, 1961), respectively].…”

The effects of protein-deprivation on the sexual activity and reproductive fitness of male onion flies, Delia antiqua (Meigen) (Diptera: Anthomyiidae), were investigated under laboratory conditions. The percentage of males inseminating gravid females, the magnitude of ovipositional response, and the total numbers of eggs deposited in 1:1 or 1:10 male:female matchings over two days was unaffected by deprivation of dietary protein. The LT 50 's (median survival time) for solitary males provided proteinaceous, sucrose, or water diets were 38.0, 25.8, and 6.0 days, respectively. Yet independent of diet effects, males lost 50% of their wing tissue by fragmentation after 26 days, suggesting that wing condition is more important in determining male reproductive fitness than longevity. Male mating frequency in single pairings with previtellogenic females deprived of proteinaceous diet for ten days was similar to that of gravid, protein-fed females. In no-choice and choice mating bioassays at a 10:1 female:male ratio, however, males inseminated significantly fewer previtellogenic than gravid females over 24 h. Despite evidence for male autogeny, removal of exogenous protein resources in the Allium agroecosystem may have important effects on the reproductive competency and fecundity of D. antiqua.
