Regulation of insect behavior by non-coding RNAs

The adaptation of insects to environments relies on a sophisticated set of behaviors controlled by molecular and physiological processes.Over the past several decades,accumulating studies have unveiled the roles of non-coding RNAs(nc RNAs)in regulating insect behaviors.nc RNAs assume particularly pivotal roles in the behavioral plasticity of insects by rapidly responding to environmental stimuli.nc RNAs also contribute to the maintenance of homeostasis of insects by fine-tuning the expression of target genes.However,a comprehensive review of nc RNAs'roles in regulating insect behaviors has yet to be conducted.Here,we present the recent progress in our understanding of how nc RNAs regulate various insect behaviors,including flight and movement,social behavior,reproduction,learning and memory,and feeding.We refine the intricate mechanisms by which nc RNAs modulate the function of neural,motor,reproductive,and other physiological systems,as well as gene expression in insects like fruit flies,social insects,locusts,and mosquitos.Furthermore,we discuss potential avenues for future studies in nc RNA-mediated insect behaviors.
