Our expectations for the evolution of chemical signals in response to sexual selection are uncertain. How are chemical signals elaborated? Does sexual selection result in complexity of the composition or in altered quantities of expression? We addressed this in Drosophila pseudoobscura by examining male and female cuticular hydrocarbons (CHs) after 82 generations of elevated (E) sexual selection or relaxed sexual selection through monogamy (M). The CH profile consisted of 18 different components. We extracted three eigenvectors using principal component analysis that explained 72% of the variation. principal component (PC)1 described the amount of CHs produced, PC2 the trade-off between short-and long-chain CHs and PC3 the trade-off between apparently arbitrary CHs. In both sexes, the amount of CHs produced was greater in flies from the E treatment. PC3 was also higher, indicating that sexual selection also influenced the evolution of CH composition. The sexes differed in all three PCs, indicating substantial sexual dimorphism in this species, although the magnitude of this dimorphism was not increased as a result of our experimental evolution. Collectively, our work provides direct evidence that sexual selection plays an important role in the evolution of CHs in D. pseudoobscura and that both increased quantity and overall composition are targeted.

“…females have been shown to remate after approximately 6 days. a time by which sperm stores become depleted by 78% and female fertility begins to drop (Gromko & Pyle, 1978;Pyle & Gromko, 1978; see also Manning, 1967;Pruzan-Hatchkiss et al, 1981; but see Fuerst er al.. 1973).…”

ABSTRACT. The adaptive significance of multiple mating by female Gryllus bimaculatus (De Geer) was investigated. Multiple mating prevented the depletion of sperm stores and, therefore, maintained high hatching success. This may not, however, explain the high frequency of remating in this species. Male‐derived egg stimulants known to be passed with sperm at mating increased the number of eggs produced only when females mated throughout their lifespans. Spermatophore consumption appeared to provide nutrients which, while they did not increase the quantity of eggs, increased egg quality as indicated by weight. Females who consumed spermatophores had a greater hatching success. While females may derive non‐genetic benefits from mating, these are apparently long‐term benefits; females must mate throughout their lives in order to accrue them. Since the benefits of mating may not be derived from individual males, the spermatophores and their contents in this species are best considered as mating effort.

“…These conflicting results may be due in part to different morphological mutant markers or experimental designs used in these experiments. Two studies have indicated a productivity advantage to multiply mated D. pseudoobscura females over singly mated ones (Beckenbach, 1978;Pruzan-Hotchkiss et al, 1981). Thus there is evidence that females of this species who multiply mate do enjoy a fitness advantage such that se-lection should favor female receptivity to repeated matings.…”

“…Anderson (1974) suggested that a second mating may replenish sperm depleted by fertilization and allow a female to produce more fertilized eggs. The data from Pyle's and Gromko's (1978) study with D. melanogaster and the two studies with D. pseudoobscura (Beckenbach, 1978;Pruzan-Hotchkiss et al, 1981) show that productivity declines in once-mated females but continues in those given an opportunity to remate, so that sperm replenishment must be a major factor in the increased productivity of multiply mated females. The data show, however, that sperm replenishment is not the only factor.…”

Sperm Utilization in Once- and Twice-Mated Drosophila pseudoobscura Females

Abstract: Mating behavior in the fruit fly, Drosophila, has been studied extensively (Ehrman and Parsons 1976). It is known, for example, that females of many species in this genus copulate repeatedly both in the laboratory (Pruzan 1976;
