Take care of beneficial insects

December 1, 2014

KEY PRACTICE: Use insecticides judiciously and employ strategies that may increase populations of some beneficial insects and reduce mortality of some parasitoids. These strategies include reducing tillage, leaving tall stubble to improve overwinter survival and intercropping.

Beneficial insects provide valuable contributions to canola production, both in terms of pollination of crops and predation of insect pests. Monitoring populations of both pest insects and parasitoids can help canola producers make decisions about the need for insecticide applications.

Canola growers should also employ strategies that may increase populations of some beneficial insects and reduce mortality of some parasitoids. These include limited spraying during flowering to protect bees and other pollinators, and reducing tillage, leaving tall stubble to improve overwinter survival, intercropping and even leaving lateemerging weeds in canola to bolster dominant predator counts.
