Which of the following is NOT considered a beneficial insect?

• A. A. Damselflies
• B. B. Ladybugs
• C. C. Parasitic wasps
• D. D. Army worm

Answer: (D)

The army worm is not considered a beneficial insect because it is primarily a pest that can cause significant damage to crops, particularly in agricultural settings. In contrast, damselflies, ladybugs, and parasitic wasps are beneficial insects that contribute positively to ecosystems and agriculture. Damselflies are effective hunters of smaller pests, including mosquitoes. Ladybugs are known for consuming aphids and other harmful pests, providing a natural form of pest control. Parasitic wasps help manage pest populations by laying their eggs in or on other insects, ultimately leading to the control of pest species. All these beneficial insects help promote healthier ecosystems and can reduce the reliance on chemical pesticides in farming practices.
