Courtship feeding in tree crickets increases insemination and female reproductive life span
Article Abstract:
Courtship feeding is known to affect the reproductive patterns of most female insects, but the effect of gift quality is ill understood. It has recently been clarified that the fitness consequences of successive matings control sexual selection in both sexes. A new study of the black-horned tree cricket investigates whether fecundity is due to variations in gift size or the related consequences of variability in ejaculate sized and to determine the consequences of courtship feeding. It is shown that male size has no effect on female reproduction and that gland-feeding duration influences gift size.

Lifetime mating success in male sagebrush crickets: sexual selection constrained by a virgin male mating advantage
Article Abstract:
Virgin males in sagebrush cricket obtain more matings, demonstrating a virgin male mating advantage. Females prefer virgin male partners as they can feed on their hindwings during copulation. Adult male longevity and the number of nights spent singing during the mating season has direct correlation with male mating success. Findings suggest that chorus tenure plays a crucial role in male mating success and is related to male mating history. While spatial distribution of males can vary within seasons, virgin male mating success is a constraining factor in opportunity for sexual selection.

Acoustic signalling and its relation to male mating success in sagebrush crickets
Article Abstract:
Acoustic signals play an important role in the mating behavior of crickets and lack of calling ability eliminated male crickets chances of attracting a female, in a free-living population. In a study, male crickets calling ability was abolished and its effect analyzed. Courting activity of crikets was also studied through video recordings. Elimination of calling ability ended male mating success, indicating that females select their mates almost solely on the basis of male songs. While females preferred virgin males, they were willing to copulate with non-virgin males.
