What are the four major pest groups?

1. Insects, Mammals, Weeds, Bacteria

2. Weeds, Invertebrates, Plant disease agents, Vertebrates

3. Birds, Fungus, Arachnids, Fungi

4. Insects, Fungi, Microorganisms, Rodents

The correct answer is: Weeds, Invertebrates, Plant disease agents, Vertebrates

The four major pest groups consist of weeds, invertebrates, plant disease agents, and vertebrates. Weeds are plants that are considered undesirable in particular situations, often competing with crops for resources. Invertebrates encompass a wide range of pests, including insects and arachnids, and are significant due to their impact on plants and agriculture. Plant disease agents refer to organisms that cause diseases in plants, which can include bacteria, viruses, and fungi. Lastly, vertebrates include animals like rodents and birds that can cause damage to crops and stored products. This classification is important for pest management strategies, as each group may require different approaches for control and mitigation. Understanding the specific characteristics and behaviors of these groups helps in effective pest management and contributes to sustainable agricultural practices.
