For example, vegetables and fruits are considered minor crops in many areas, and new insecticides are less likely to be registered or existing ones re-registered. Populations of many major vegetable and fruit insect pests possess resistance to insecticides. Also, vegetable and fruit growers, especially fresh market producers with small and diverse operations and roadside stands, are highly visible to the public. The application of pesticides is frequently obvious and may result in conflicts with urban neighbors. Alternatives that would reduce the need for pesticide use could help alleviate some of these conflicts.
All insect pests have natural enemies.
The use of these organisms to manage pests is known as biological control. Conservation of natural enemies is probably the most important biological control practice readily available. Through the use of selective insecticides and the judicious use of broader spectrum materials, natural enemies can exist and exert their impact on pest populations. The future of biological control is promising, but this tactic will constitute just one of many pest management options. Many obstacles will need to be overcome before biological control can reach its full potential.
