Mating behavior of the bronze birch borer, Agrilus anxius, was investigated under laboratory and outdoor conditions. Propensity to mate was greater for beetles more than 1-d-old. Duration of copulation tended to increase with increasing beetle age; 87% of mated females were inseminated and subsequently avoided sexual contact. Males mated more than once; previously mated males copulated sooner and for longer periods of time than naive males. Mating frequency did not influence female reproductive success.

The genetics of mating behavior in Japanese quail was investigated in replicated lines selected for high or low number of completed matings and the random bred control which served as the base population for the selected lines. Comparisons involved the parental lines, F1, F2, and backcross generations. Results indicate that mating frequency is influenced by additive and nonadditive genetic variation with the former being the primary heritable influence. The relationships between mating behavior, cloacal gland size, and relative aggressiveness suggest that selection for mating frequency influences factors commonly affecting these traits.

Qualitative and quantitative data obtained from lines of chickens divergently selected for male mating ability and from the unselected randombred control population were used to evaluate the relationship of comb type alleles and mating behavior. An apparent antagonistic relationship was found between the rose (R) allele and low cumulative number of completed matings in the low mating line, while the opposite association was found for the pea (P) allele. No association was found between alleles of the rose and pea loci and mating ability in the high mating or control lines. An antagonistic relationship was indicated between the rough (He+) allele and a high cumulative number of matings. These results support the hypothesis that two genetical systems interact to influence the mating frequency of male chickens and further suggest that alleles of the rose, rough, and pea loci should not be used as marker genes to estimate genetic drift in random mating populations maintained by natural matings.

AbstractAlong with sperm, in many taxa male ejaculates also contain a complex mixture of proteins, peptides and other substances found in seminal fluid. Once seminal fluid proteins (SFPs) are transferred to the mating partner, they play crucial roles in mediating post-mating sexual selection, since they can modulate the partner’s behavior and physiology in ways that influence the reproductive success of both partners. One way in which sperm donors can maximize their own reproductive success is by changing the partners’ (sperm recipient’s) postcopulatory behavior to prevent or delay re-mating, thereby decreasing the likelihood or intensity of sperm competition. We therefore adopted a quantitative genetic approach combining gene expression and behavioral data to identify candidates that could mediate such a response in the simultaneously hermaphroditic flatwormMacrostomum lignano. We identified two putative SFPs - Mlig-pro46 and Mlig-pro63 - that exhibit a negative genetic correlation between transcript expression and mating frequency. Importantly, however, in one of the two different group sizes, differing in their sperm competition level, in which we measured genetic correlations, these same two transcripts are also linked to a second post-mating behavior inM. lignano, namely the ‘suck’ behavior of recipients in which, upon ejaculate receipt, the worm places its pharynx over its female genital opening and appears to attempt to remove ejaculate components. To therefore investigate directly whether these two candidates manipulate partner behavior, and test whether this impacts on competitive fertilization success, we performed a manipulative experiment using RNA interference-induced knockdown to ask how loss of Mlig-pro46 and Mlig-pro63 expression, singly and in combination, affects mating frequency, partner suck propensity and both defensive and offensive sperm competitive ability (P1andP2, respectively). None of the knock-down treatments impacted strongly on mating frequency or sperm competitive ability, but the knock-down of Mlig-pro63 resulted in a significantly decreased ‘suck’ propensity of mating partners. This suggests that Mlig-pro63 may normally act as a cue in the ejaculate to trigger recipient suck behavior, though the functional and adaptive significance of these two seminal proteins from a donor perspective remains enigmatic.
