Genetic sire effects on the fighting ability of sons and daughters and mating success of sons in a scorpionfly

摘要: Field-collected males of the scorpionfly Panorpa vulgaris (Insecta: Mecoptera: Panorpidae) were separated on basis whether or not they could produce salivary nuptial food during matings in laboratory. Adult must feed to secret gifts. Males who secrete saliva mating designated nutritionally ‘high’ and ‘low’. This designation may reflect differences ability two types compete with conspecifics for habitat. Nutritionally high low fathers paired haphazardly virgin mates, all whom full siblings. The adult sons won significantly more fights mates than when placed competition food. daughters fathers. These sire effects offspring performance confounded by body size contestants. Bilateral symmetry is heritable, differs between categories categories, sires their are bilaterally asymmetrical. genetic paternal fitness components give rise female choice based quality potential sires.
