Extrafloral nectaries (EFNs) are nectar-secreting glands on vegetative organs that mediate indirect plant defense by recruiting predatory arthropods. Documented in over 4,999 species across 129 families, with at least 457 independent evolutionary origins,

Bumblebees learn to use antennal and tarsal taste to predict the presence of nectar rewards in flowers. [PDF]
Learning cues such as tastes associated with palatable food is an important mechanism animals have for foraging optimally. Insects can use gustatory receptor neurons (GRNs) in their mouthparts to detect nutrients and toxins, but they also taste compounds

Experimental setup for dsRNA feeding in Brassicogethes aeneus to evaluate the effect of a synthetic polymer nanocarrier on RNAi efficiency. The experiment assessed whether the nanocarrier enhances RNAi after oral dsRNA delivery. (a) Stability of dsRNA–nanocarrier complexes was tested in simulated gut conditions. (b) Gene expression of αCOP and dre4 was

In the nectar, there are answers: exploring the intersection of colored nectars and reactive oxygen species in manipulating pollinator behavior. [PDF]
Summary Nectar, a vital mediator of plant–pollinator interactions, exhibits remarkable chemical diversity beyond sugars, including reactive oxygen species and specialized metabolites such as pigments. Colored nectars, present in over 70 species, function

Effects of bioinsecticide exposure route on aphids and their natural enemies in oilseed rape
Fatty acids, silicone polymers and surfactants reduced aphid numbers but caused natural enemy mortality under direct exposure, while minimal residual activity suggests potential for targeted, compatible use in integrated pest management. Abstract BACKGROUND Myzus persicae Sulzer and Brevicoryne brassicae L.

Natural Product Medicines for Honey Bees: Perspective and Protocols
The western honey bee remains the most important pollinator for agricultural crops. Disease and stressors threaten honey bee populations and productivity during winter- and summertime, creating costs for beekeepers and negative impacts on agriculture. To

Host‐plant selection is a key factor driving the ecology and evolution of insects. While the majority of phytophagous insects is highly host specific, generalist behavior is quite widespread among bees and presumably involves physiological adaptations ...

Astigmatid mites provide low‐cost supplemental food for Macrolophus pygmaeus, supporting survival and development, with population‐specific responses and Acarus siro and Carpoglyphus lactis as the most promising alternatives. Abstract BACKGROUND Early establishment of Macrolophus pygmaeus in crops depends on the availability of supplemental food ...

Microbiome‐mediated chemical communication in insects: Implications for pest management
Microbiome–semiochemical interactions involve the following processes: direct microbial synthesis, host gene regulation, precursor biotransformation, microbiome modulation and indirect ecological signaling. Abstract Insects rely on semiochemicals to regulate aggregation, mating, foraging, and host selection. This review synthesizes evidence that insect‐
