- Abstract:
- Most insects are not pests. Only those that feed on desirable plants or transmit disease cause problems for gardeners. Many insects are very useful. Some are pollinators of fruits, flowers, and vegetables, while others help control insect pests. There are three types of beneficial insects: predators, pollinators, and parasitoids.
