Chemistry of floral rewards: intra‐ and interspecific variability of nectar and pollen secondary metabolites across taxa
Floral chemistry mediates plant interactions with pollinators, pathogens, and herbivores, with major consequences for fitness of both plants and flower visitors. The outcome of such interactionsExpand

Nectar chemistry modulates the impact of an invasive plant on native pollinators
1. Invasive species are considered a main driver of pollinator declines, yet the direct effects of invasive alien plants on pollinators are poorly understood. 2. Abundant, invasive plant speciesExpand

Insecticidal activity of Tithonia diversifolia and Vernonia amygdalina
Abstract The diversity of synthetic pesticides has been reduced through regulation especially in the European Union, leading to a resurgence of interest in natural plant products for pest control.Expand

Crop Domestication Alters Floral Reward Chemistry With Potential Consequences for Pollinator Health
Crop domestication can lead to weakened expression of plant defences, with repercussions for herbivore and pathogen susceptibility. However, little is known about how domestication alters traits thatExpand

Novel Agmatine Derivatives in Maerua edulis With Bioactivity Against Callosobruchus maculatus, a Cosmopolitan Storage Insect Pest
Food security in developing countries is threatened by crop pests and ectoparasites in livestock. Strategies for their management still rely on synthetic pesticides which are not always effective andExpand

Distasteful Nectar Deters Floral Robbery
Toxic nectar is an ecological paradox [1, 2]. Plants divert substantial resources to produce nectar that attracts pollinators [3], but toxins in this reward could disrupt the mutualism and reduceExpand

Phytochemical Analysis of Tephrosia vogelii across East Africa Reveals Three Chemotypes that Influence Its Use as a Pesticidal Plant
Tephrosia vogelii is a plant species chemically characterized by the presence of entomotoxic rotenoids and used widely across Africa as a botanical pesticide. Phytochemical analysis was conducted toExpand

Mechanisms in mutualisms: a chemically mediated thrips pollination strategy in common elder
Main conclusionThis study provides first evidence of a thrips species pollinating Sambucus nigra and describes how interactions are driven by plant biochemical signalling and moderated by temporalExpand

Secondary metabolites from nectar and pollen: a resource for ecological and evolutionary studies.
Floral chemistry mediates plant interactions with herbivores, pathogens, and pollinators. The chemistry of floral nectar and pollen, the primary food rewards for pollinators, can affect both plantExpand
