Nuptial gifts
Figure 1. Nuptial gifts of insects. An array of nuptial gifts provided by male insects. Top left: during mating, a female dance fly (Diptera: Empididae) feeds upon a dead insect provided by her mate (Photo: Rob Knell). Top right: a male scorpionfly (Mecoptera: Panorpodidae) secretes a white salivary mass that will be consumed by a female during mating (Photo: Arp Kruithof). Bottom left: after m...
متن کاملCyanogenesis in plants and arthropods.
Cyanogenic glucosides are phytoanticipins known to be present in more than 2500 plant species. They are regarded as having an important role in plant defense against herbivores due to bitter taste and release of toxic hydrogen cyanide upon tissue disruption, but recent investigations demonstrate additional roles as storage compounds of reduced nitrogen and sugar that may be mobilized when deman...
متن کاملMolecular dissection of nuptial gifts in divergent strains of Ostrinia moths: Nuptial gifts in Ostrinia moths
Seminal fluid proteins (SFPs) produced in the male accessory glands and ejaculatory duct are subject to strong sexual selection, often evolve rapidly and therefore may play a key role in reproductive isolation and species formation. However, little is known about reproductive proteins for species in which males transfer ejaculate to females using a spermatophore package. By combining RNA sequen...
متن کاملSexual conflict over nuptial gifts in insects.
Edible and seminal gifts that male arthropods transfer to their mates range from important material donations to items that provide little direct benefit. Recent reviews and research have emphasized the negative effect of gifts on female fitness, suggesting that male donations reduce the female's remating rate below her optimum or even that nuptial feeding is a net detriment to her fitness. How...
متن کاملFemale bushcrickets fuel their metabolism with male nuptial gifts.
In many arthropods, such as bushcrickets, males donate protein-rich nuptial gifts-so-called spermatophores-to females, which females ingest while the sperm enter the female's reproductive tract. Previously, it was shown that females route spermatophore nutrients over the course of hours and days to egg production or body synthesis. We investigated whether female bushcrickets fuel their metaboli...
