CDFA Pest Prevention Plant Regulation Practice Exam

Burrowing nematode is classified as which type of organism?

1. A virus-like disease of potatoes

2. An endoparasitic nematode

3. A parasitic seed plant

4. A saprophytic disease

The correct answer is: An endoparasitic nematode

Burrowing nematode is classified as an endoparasitic nematode due to its biological characteristics and life cycle. Endoparasitic nematodes are organisms that live within their hosts and feed on the host's tissues, often leading to damage and disease. In the case of the burrowing nematode, it specifically targets plant roots and can cause significant harm to various crops, particularly potatoes. This parasite enters the plant tissue and affects the plant's ability to absorb nutrients and water, often leading to stunted growth and reduced yield. The classification of burrowing nematode as an endoparasitic nematode is crucial for understanding its role in agriculture and pest management strategies, as effective control methods typically focus on reducing the nematode's population in the soil and protecting host plants. This understanding informs practices that can mitigate the damage caused by such pests in agricultural settings.
