Honey bees build large nests, called hives, consisting of wax combs of hexagonal cells (Fig. 22.26) in which they rear the brood and store pollen and nectar. Feral, or “wild,”honey bee coloniesconstruct nests in cavities of hollow trees and in attics and wall voids of human dwellings....
precipitation could potentially influence pathogen survival on flowers and thereby their transmission40. Furthermore, climatic variables affect vegetation phenology43, flower attractiveness44and diversity45, which may alter the transmission network via flowers23, as well as quality, quantity of floral resourc...
' We need to know much more about bees and their relationships with plants before this question can be answered. GBees, then, are vital to our survival. Furthermore, much of the visual impact of human environments derives from vegetation, and most vegetation is dependent on bees for ...

[3]. Other more dramatic examples are those of bat viruses transmitted to human populations. These include Nipah and Hendra viruses as well as the severe acute respiratory syndrome coronavirus (SARS-CoV-2) that have caused human mortalities [4,5]. The term pathogen spillover in bee-related ...
Extinction of bees will affect plants, animals, availability of fuels, topography, clothing and of course, human life. Effects on plants Some plants are pollinated by wind, but that rate is very slow. Insects are the primary pollinators on the planet. Beetles and butterflies also pollinate, ...
