Which insect is commonly used as a beneficial organism in IPM?

• A. Lacewings
• B. Spiders
• C. Aphids
• D. Scale insects

Answer: (A)

Lacewings are widely used as beneficials in IPM because their larvae are voracious predators of many soft-bodied pests, especially aphids, whiteflies, and other small injurious insects. These larvae, often called aphid lions, actively hunt and consume pest eggs and larvae, providing rapid suppression of outbreaks. The adults feed on nectar and pollen, which helps sustain their populations in crops and supports ongoing pest control. Because lacewings are released as biological control agents and are compatible with selective pesticides, they’re a cornerstone of many IPM programs in both fields and greenhouses. Spiders are beneficial but are not typically released as a standard IPM insect, while aphids and scale insects are pests, not beneficials.
