Which insect group primarily serves as biological control parasites?

The primary group of insects that serves as biological control parasites is found within the wasps and flies category. This group includes various species that lay their eggs in or on host insects. As the larvae develop, they feed on the host, ultimately leading to the host's demise. This method of parasitism is a natural form of pest control, as these wasps and flies target specific pest species, thereby helping to regulate pest populations in agricultural and natural ecosystems.

Wasps, particularly those from the family Ichneumonidae and Braconidae, are well-known for their role as biocontrol agents. They are specific in their selection of host organisms, making them effective in managing pest populations without harming beneficial insects or pollinators. Some flies, such as the tachinids, also participate in this form of biological control. Recognizing this, many agricultural practices incorporate these natural enemies to reduce reliance on chemical pesticides, promoting more sustainable pest management strategies.

In contrast, while ants, ladybugs, and beetles do play roles in controlling pest populations, they typically do so through predation or scavenging rather than through parasitism. Ladybugs are notorious for consuming aphids, and beetles may feed on a variety of pests but
