Parasitoid wasps are a unique group of insects that lay their eggs inside or on the bodies of other insects, often referred to as hosts. Once the eggs hatch, the larvae feed on the host, eventually leading to its death. This process is a form of parasitism, where the wasp benefits at the expense of the host. These wasps play a crucial role in controlling pest populations in ecosystems. By targeting harmful insects, parasitoid wasps help maintain a balance in nature, making them valuable for agriculture and natural pest management strategies.
