Which is an example of a natural predator used in pest control?

Ladybugs are a prime example of a natural predator used in pest control. These beneficial insects primarily feed on aphids, mites, and other soft-bodied pests that can damage plants in gardens and agricultural settings. By introducing or encouraging ladybugs in an environment, gardeners and farmers can effectively reduce pest populations without relying on synthetic pesticides, thus promoting a healthier ecosystem and minimizing chemical exposure.

In contrast, the other options listed represent chemical control methods rather than biological ones. Malathion and glyphosate are both pesticides; Malathion is an organophosphate insecticide, and glyphosate is a systemic herbicide used to kill weeds. Pyrethrum is derived from chrysanthemum flowers and is a natural insecticide, but it does not function as a predator. Instead, it acts as a pesticide that can kill pests directly. Therefore, ladybugs stand out as a beneficial organism that actively preys on agricultural pests, making them a natural choice for integrated pest management strategies.
