What is a recommended control approach for two-spotted spider mites?

• A. Horticultural oils and insecticidal soaps control spider mites and conserve natural predators.
• B. Broad-spectrum miticides are always the best option.
• C. Soil drenches with fungicides will control mites.
• D. Manual removal of leaves is the only effective method.

Answer: (A)

Two-spotted spider mites are best managed with products that work on contact on the leaf surface and that spare natural enemies, which helps keep populations in balance over time. Horticultural oils and insecticidal soaps fit this approach because they physically coat and smother mites and their eggs, reducing populations without broadly harming most beneficial predators. This selective action is a key advantage in integrated pest management, as conserving natural enemies helps prevent rebounds and keeps control sustainable with fewer repeat treatments. Other approaches are less favorable in typical IPM. Broad-spectrum miticides can wipe out beneficial insects and predatory mites, often leading to a quicker reinfestation once the chemical loses effectiveness. Soil drenches with fungicides don’t reach the mites that live on and under the leaves, so they’re not effective for this pest. Manual leaf removal is impractical for most plants and sizes of infestations, providing only limited, temporary relief.
