What is the role of beneficial insects in gardening?

1. They harm the crops

2. They assist with pollination and pest control

3. They compete with plants for nutrients

4. They spread diseases among crops

The correct answer is: They assist with pollination and pest control

Beneficial insects play a vital role in gardening mainly by assisting with pollination and pest control. Pollination is crucial for the reproduction of many plants, as it helps in the transfer of pollen from male to female parts, leading to fruit and seed production. Insects like bees and butterflies are key pollinators that enhance the yield and quality of crops. In addition to pollination, beneficial insects also contribute to pest control. Many of these insects, such as ladybugs and lacewings, feed on harmful pests like aphids and caterpillars. By naturally regulating pest populations, beneficial insects help reduce the need for chemical pesticides, promoting a healthier ecosystem and environment. Understanding the beneficial role these insects play highlights their importance in sustainable gardening practices, which aim to balance plant health and ecological integrity.
