What type of nematodes are developed to be used as insect controls and are also known as "entomopathic nematodes"?

Entomopathic nematodes are specifically known for their role in biological control, particularly in managing insect pests. These nematodes are parasitic, meaning they rely on a host—typically an insect—during part of their life cycle. When these nematodes encounter a suitable insect host, they invade it, often leading to the host's death. Through this parasitic relationship, they can effectively reduce pest populations in a variety of agricultural and horticultural settings.

The correct term for these nematodes highlights their specific function in controlling insect pests, thereby making them valuable in integrated pest management strategies. By utilizing them, growers can minimize reliance on chemical pesticides, promoting a more environmentally friendly approach to pest control.
