Nanotechnologies associated to floral resources in agri-food sector
Acta Agronómica, 2018 Nanotechnology advent in agri-food sector is set to prompt next revolution in agricultural engineering. However, there is a perpetually rising need for development of new nanotechnologies that could synchronically work with various agrochemicals such as ...

Shifts in honeybee foraging reveal historical changes in floral resources. [PDF]
Commun Biol, 2021 AbstractDecreasing floral resources as a result of habitat loss is one of the key factors in the decline of pollinating insects worldwide. Understanding which plants pollinators use is vital to inform the provision of appropriate floral resources to help prevent pollinator loss.

Salvage of floral resources through re-absorption before flower abscission. [PDF]
Sci Rep, 2020 AbstractPlants invest floral resources, including nectar and pigment, with likely consequent reproductive costs. We hypothesized that plants, whose flowers abscise with age, reabsorb nectar and pigment before abscission. This was tested with flowers of Rhododendron decorum, which has large, conspicuous white flowers that increasingly abscise corollas ...

Pollinator behaviour and resource limitation maintain honest floral signalling [PDF]
Functional Ecology, 2021 Abstract In many communication systems, signal receivers profit from honest signals that indicate the signaller's quality, whereas low‐quality signallers should profit from cheating. Under such a conflict of interests between signallers and signal receivers, the maintenance of honest signals presents a puzzle.

Bee nutrition and floral resource restoration [PDF]
Current Opinion in Insect Science, 2015 Bee-population declines are linked to nutritional shortages caused by land-use intensification, which reduces diversity and abundance of host-plant species. Bees require nectar and pollen floral resources that provide necessary carbohydrates, proteins, lipids, and micronutrients for survival, reproduction, and resilience to stress.

Dependency on floral resources determines the animals’ responses to floral scents [PDF]
Plant Signaling & Behavior, 2010 Animal-pollinated angiosperms either depend on cross-pollination or may also reproduce after self-pollination - the former are thus obligately, the latter facultatively dependent on the service of animal-pollinators. Analogously, flower visitors either solely feed on floral resources or complement their diet with these, and are hence dependent or not ...

Floral Resources for Trissolcus japonicus, a Parasitoid of Halyomorpha halys. [PDF]
Insects, 2020 The egg parasitoid Trissolcus japonicus is the main candidate for classical biocontrol of the invasive agricultural pest Halyomorpha halys. The efficacy of classical biocontrol depends on the parasitoid’s survival and conservation in the agroecosystem. Most parasitoid species rely on floral nectar as a food source, thus identifying nectar sources for T.

Chemical Ecology of Floral Resources in Conservation Biological Control
Annual Review of Entomology, 2023 Conservation biological control aims to enhance populations of natural enemies of insect pests in crop habitats, typically by intentional provision of flowering plants as food resources. Ideally, these flowering plants should be inherently attractive to natural enemies to ensure that they are frequently visited.

Insect-flower interaction network structure is resilient to a temporary pulse of floral resources from invasive Rhododendron ponticum. [PDF]
PLoS ONE, 2015 Invasive alien plants can compete with native plants for resources, and may ultimately decrease native plant diversity and/or abundance in invaded sites. This could have consequences for native mutualistic interactions, such as pollination.
