Releasing beneficial insects to a crop is a great way to control pests
This method is called augmentative bio-control. It is used to release insects that are the natural enemies of the pest.
2 approaches to this method of bio-control:
- Inoculative Releases: The preventative release of small numbers of beneficial insects to keep the pest levels low and develop a beneficial insect colony to maintain the low pest levels
- Inundative Releases: The release of large numbers of beneficial insects to reduce the pest levels quickly and build a colony of beneficial insects
