An increasing number of recent studies show that nectar-inhabiting microorganisms influence plant fitness by mediating interactions between plants and pollinators. However, whether the effects nectar microbes extend beyond pollination to affect subsequent stages reproduction remains largely unknown. This study aims explore can indirectly fruit consumption birds, which be essential for seed dispersal germination. Wild flowers Eurya japonica trees were experimentally inoculated with yeast Metschnikowia reukaufii bacterium Acinetobacter boissieri, both had been previously isolated frequently from E. flowers. In this experiment, I examined these changed female reproductive success understory tree. Experimental inoculation yeasts decreased set compared those bacteria, control. Furthermore, fruits higher tended larger, larger more likely consumed seed-dispersing including Japanese white-eye Zosterops japonica, brown-eared bulbul Hypsipetes amaurotis, Daurian redstart Phoenicurus auroreus. These results suggest have potential influencing not only plant-pollinator interactions, but also modifying plant-frugivore via changes in interactions.

Nectar, the main floral reward for pollinators, varies greatly in composition and concentration. The assumption that nectar quality is equivalent to its sugar (energy) concentration too simple. Diverse non-sugar components, especially amino acids secondary metabolites, play various roles nutrition health of pollinators. Many compounds have indirect effects by altering foraging behaviour pollinators or protecting them from disease. This review also emphasizes water component nectar, often ignored because evaporative losses difficulties sampling small volumes. Nectar properties vary with environmental factors, pollinator visits microbial contamination.

Mosquitoes, males and females, rely on sugar-rich resources including floral nectar as a primary source of sugar to meet their energy nutritional needs. Despite advancements in understanding mosquito host-seeking blood-feeding preferences, significant gaps our knowledge the chemical ecology mediating mosquito-nectar associations remain. The influence such association with behavior, resulting effects fitness are also not totally understood. It is that frequently acts natural habitat for various microbes (e.g., bacteria yeast), which substantially alter characteristics, influencing flower-visiting insects mosquitoes. role nectar-inhabiting shaping nectar-mosquito interactions remains, however, under-researched.

Floral nectar is frequently colonized by microbes among which bacteria and yeasts are the most abundant. These have ability to alter characteristics with consequences for whole community of flower-visiting insects. Recent research carried out on natural enemies insect herbivores has shown that microbe-mediated changes in traits can influence foraging behavior life history parasitoids.
