Parasitoid wasps are a diverse group of insects that serve as natural enemies to a variety of other insects, primarily through parasitism. These wasps lay their eggs inside or on the bodies of host insects, where the developing larvae feed on the host and eventually kill it. This unique reproductive strategy makes parasitoid wasps important for biological control of pest insects in agriculture and natural ecosystems. Research on parasitoid wasps involves studying their biology, behavior, ecology, and interactions with their hosts, with the goal of improving their effectiveness as biocontrol agents and understanding their impact on ecosystems.
