Society has recognized the value of ecosystem services. Insects are one of the most diverse groups, playing a significant role in maintaining ecosystem function and ecological balance, and fulfilling human demands. Insect ecological services are the functional roles in ecosystem processes, benefiting humans with goods and services such as pollination, pest control and decomposition. Insect ecological services include provisioning, regulation, cultural and support services. The economic value of insect ecological services can be divided into direct鄄, indirect鄄, option鄄 and existence values. The ecological regulating services of insects involve pollination, biological control and dung burial. Insects perform pollination services to crops, vegetables and fruits which are an important ecological service. Pollination is usually the transfer of pollen from the male sex organ to the receptive portion of the female sex organ in flowering plants. Insect pollinators are adapted to many flowering plant species and are provided with primary rewards that attract (i.e., " attract and reward冶) and establish pollen vectors returning to flowers. Rewards include nectar, pollen, lipid secretions, food bodies, scents, resins, and
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
