No evidence that presence of sexually transmitted infection selects for reduced mating rate in the two spot ladybird, Adalia bipunctata
Sexually transmitted infections (STIs) are common in animals and plants, and frequently impair individual fertility. Theory predicts that natural selection will favour behaviours that reduce the chance of acquiring a STI. We investigated whether an STI, Coccipolipus hippodamiae has selected for increased rejection of mating by female Adalia bipunctata as a mechanism to avoid exposure. We first ...
متن کاملExtreme Costs of Mating for Male Two-Spot Ladybird Beetles
Male costs of mating are now thought to be widespread. The two-spot ladybird beetle (Adalia bipunctata) has been the focus of many studies of mating and sexual selection, yet the costs of mating for males are unknown. The mating system of A. bipunctata involves a spermatophore nuptial gift ingested by females after copulation. In this study, we investigate the cost to males of mating and of tra...
متن کاملSexual selection and mating patterns in a mammal with female-biased sexual size dimorphism
In mammals, species with highly male-biased sexual size dimorphism tend to have high variance in male reproductive success. However, little information is available on patterns of sexual selection, variation in male and female reproductive success, and body size and mating success in species with female-biased size dimorphism. We used parentage data from microsatellite DNA loci to examine these...
متن کاملEvolution of mating preference and sexual dimorphism.
A quantitative genetic model of the joint evolution of female mating preferences and sexual dimorphism in homologous characters of the sexes is described for polygamous species with no male parental effort, such that mating preferences are selectively neutral and evolve only by indirect selection on genetically correlated characters. The male character and the homologous female character are ea...
متن کاملSexual dimorphism in the wing shape and size of the carob moth, Ectomyelois ceratoniae (Lepidoptera: Pyralidae)
پروانه‌ی کرم گلوگاه انار، Ectomyelois ceratoniae (Zeller) ، به خانواده‌ی Pyralidae و زیر خانواده‌ی Phycitinae تعلق دارد. علیرغم وجود شواهدی دال بر وجود اختلاف شکل و اندازه در جنس‌های نر و ماده‌ی بسیاری از پروانه‌ها و همچنین در اعضای این خانواده، وجود چنین اختلافی تاکنون در گونه‌ی مورد بحث گزارش نشده است. در تحقیق حاضر، دوشکلی جنسی در اندازه و شکل بال پروانه‌ی کرم گلوگاه انار روی چهار میزبان انا...
