Nectar in Plant–Insect Mutualistic Relationships: From Food Reward to Partner Manipulation
Frontiers in Plant Science, 2018 It has been known for centuries that floral and extra-floral nectar secreted by plants attracts and rewards animals. Extra-floral nectar is involved in so-called indirect defense by attracting animals (generally ants) that prey on herbivores, or by ...

Inter-Individual Nectar Chemistry Changes of Field Scabious, Knautia arvensis
Insects, 2020 Nectar is crucial to maintain plant-pollinator mutualism. Nectar quality (nutritional composition) can vary strongly between individuals of the same plant species.

Foliar herbivory increases sucrose concentration in bracteal extrafloral nectar of cotton
PLoS ONE, 2021 Cultivated cotton, such as Gossypium hirsutum L., produces extrafloral (EF) nectar on leaves (foliar) and reproductive structures (bracteal) as an indirect anti-herbivore defense.

Plants, 2020 Floral nectar, being a primary reward for insect visitors, is a key factor in shaping plant–pollinator interactions. However, little is known about the variability in nectar traits, which could potentially affect pollinators and the reproduction of the ...

Novel nectar robbing negatively affects reproduction in Digitalis purpurea
Ecology and Evolution, 2021 With many plant–pollinator interactions undergoing change as species’ distributions shift, we require a better understanding of how the addition of new interacting partners can affect plant reproduction. One such group of floral visitors, nectar robbers,

Acta Agrobotanica, 2017 Floral and extra-floral nectars are secretions elaborated by specific organs (nectaries) that can be associated with plant reproductive structures (the so-called floral nectaries found only in angiosperms) or vegetative parts (extrafloral nectaries ...

Do honeybees shape the bacterial community composition in floral nectar? [PDF]
PLoS ONE, 2013 Floral nectar is considered the most important reward animal-pollinated plants offer to attract pollinators. Here we explore whether honeybees, which act as pollinators, affect the composition of bacterial communities in the nectar.

Differential effects of jasmonic acid treatment of Brassica nigra on the attraction of pollinators, parasitoids, and butterflies [PDF]
, 2008 Herbivore-induced plant defences influence the behaviour of herbivores as well as that of their natural enemies. Jasmonic acid is one of the key hormones involved in both these direct and indirect induced defences.

Dynamical transitions in a pollination--herbivory interaction [PDF]
, 2015 Plant-pollinator associations are often seen as purely mutualistic, while in reality they can be more complex. Indeed they may also display a diverse array of antagonistic interactions, such as competition and victim--exploiter interactions.

Nectar Feeding by Wandering Spiders on Cotton Plants [PDF]
Environmental Entomology, 2008 Spiders are assumed to be strictly carnivorous in assessments of their nutritional and energetic requirements, their habitat preferences, and their potential as biological control agents. However, members of Salticidae (jumping spiders), Thomisidae (crab spiders), and the fast-moving Miturgidae, Anyphaenidae, and Corinnidae, all non-webbuilding ...
