Nuptial feeding encompasses any form of nutrient transfer from the male to the female during or directly after courtship and/or copulation. In insects, nuptial gifts may take the form of food captured or collected by the male, parts, or even the whole of the male's body, or glandular products of the male such as salivary secretions, external glandular secretions, the spermatophore and substances in the ejaculate. Over the past decade, there has been considerable debate over the current function… Expand
Function of the Hemolymph Nuptial Gift in the Ground Cricket, Allonemobius socius
TLDR
It is suggested that the nuptial gift in the southern ground cricket, Allonemobius socius, acts as parental investment and not as mating effort, and is not related to gift size. Expand
Could male tergal secretions be considered as a nuptial gift in the Madeira cockroach?
TLDR
It is shown that females did not gain any fitness benefit from copulating with a male with tergal secretions, but it even seems to be the contrary in terms of longevity, and neither the mating effort hypothesis nor the paternal investment hypothesis has been confirmed in this species. Expand
The effect of nuptial gift number on fertilization success in a Hawaiian swordtail cricket
In many insects, males transfer nuptial gifts to females prior to, during, or after copulation. Nuptial gifts comprise any form of non-gametic material transfer, such as glandular secretions, preyExpand
Resource-dependent nuptial feeding in Panorpa vulgaris: an honest signal for male quality
TLDR
In the present study, it is able to show that males of P. vulgaris were limited in their production of salivary secretions, and males of nutritionally high status produced more gifts than those ofNutritionally low status. Expand
Sexual conflict and the evolution of nuptial feeding
TLDR
Fitness data suggest that males providing a small or even no gift are equally successful to their large gift-giving counterparts, while the population profiles indicate that at least half of these populations are evolving towards the near or complete loss of these cannibalistic gifts. Expand
The influence of nuptial feeding and sperm transfer on the immunological cost of reproduction in the ground cricket Allonemobius socius
TLDR
The findings suggest that the nuptial gift, similar to sperm, signals the female to begin her reproductive investment, causing limited resources to be reallocated from immune function, causing the immunological cost of reproduction to be reduced. Expand
Sexual conflict over nuptial gifts in insects.
  • D. Gwynne

  • 2008
TLDR
Comparison, experimental, and natural history evidence reveal that most edible gifts of prey or glandular products provide direct benefits to females, and points out the difficulties in determining that female remating rates are suboptimal. Expand
The troublesome gift: The spermatophylax as a purveyor of sexual conflict and coercion in crickets
TLDR
This hypothesis predicts that the chemical composition of nuptial food gifts should be driven by a sexual conflict over offspring paternity, and reviews accumulated studies on decorated crickets, Gryllodes sigillatus, a species that has illuminated key elements of this evolutionary arms race. Expand
The role of male's anal horns in copulation of a scorpionfly
TLDR
The anal horns of male D. magna seem to be a male adaptation evolved to overcome female mating resistance, by promoting male domination in copulation through increasing the duration of pre- and post-gift-providing copulatory stages against female resistance and by avoiding wasting of nuptial gifts. Expand
Nuptial Gifts and Sexual Selection in Photinus Fireflies1
TLDR
Results suggest that seasonal changes in nuptial gift availability may contribute to reversals of traditional courtship roles, with male choice and female-female competition occurring as spermatophore availability declines. Expand

TLDR
Analysis of comparative data of 19 species of bushcrickets suggests that there are essentially two types of nuptial gifts; those that function to protect the males’ ejaculate during insemination with low nutritional value and no apparent effect on female fecundity and those of lower quality that serve solely to protection the male’s ejaculate.

  • 1993
TLDR
Analysis of comparative data of 28 species of bushcrickets reveals that male spermatophore size is positively correlated with female refractory period, which, in turn, correlates with male fertilization success, indicating that the variation in sperMatophore sizes is better explained by a mating‐effort function than a paternal investment function.

TLDR
The moth Utetheisa ornatrix (Lepidoptera: Arctiidae) is protected against predation by pyrrolizidine alkaloids that it sequesters as a larva from its foodplants, and females reinforce after copulation the choice mechanism they already exercise during courtship. Expand
Transfer of male secretions from the spermatophore to the female insect in Caryedon serratus (Ol.): Analysis of the possible trophic role of these secretions
TLDR
The supply of male secretions constitutes an important trophic contribution that increases females' fecundity and vitellogenesis and the extent of its importance are analyzed in Caryedon serratus. Expand
Courtship feeding in Drosophila subobscura. I. The nutritional significance of courtship feeding
TLDR
By feeding male Drosophila subobscura with stained yeast before courtship it was shown that the males transfer regurgitated crop contents to females during courtship and a comparison of crop sizes revealed that flies collected from the wild resemble the starved laboratory groups. Expand
Male Nutrient Investment in the Lepidoptera: What Nutrients Should Males Invest?
TLDR
Gwynne has devised a workable division of reproductive effort by retaining definitions of mating effort and parental effort but dividing mating effort into promiscuous and nonpromiscuous mating effort. Expand
Dynamics of ejaculate nutrient transfer in Locusta migratoria
TLDR
The results show that males transferred very significant amounts of a mixture of 16 amino acids through the ejaculate and that females transferred these to the eggs they subsequently laid, suggesting a generalized investment. Expand
Courtship Feeding in Katydids (Orthoptera: Tettigoniidae): Investment in Offspring or in Obtaining Fertilizations?
TLDR
The hypothesis that the function of "excess" maledonated nutrition is mating effort that protects the ejaculate is rejected and courtship feeding in R. verticalis may represent parental effort whereby males invest in their own zygotes. Expand
Courtship Feeding in Katydids (Orthoptera: Tettigoniidae): Investment in Offspring and in Obtaining Fertilizations
TLDR
While either of these hypotheses may have been responsible for the evolutionary origins of courtship feeding, they need not be mutually exclusive hypotheses for the current maintenance of the trait; courtship gifts that ensure complete insemination may simultaneously contribute to offspring production.
