Monitoring is the key to a successful IPM program.
IPM means making decisions based upon what insects and mites are in a crop at any given time. It includes knowing what beneficial and pest species are present, and whether the beneficial species can be effective in controlling the pests. Decisions on pest actions will depend upon the relative numbers of different life stages of pests and beneficials, and not just the absolute numbers of pests versus beneficials.
The easiest way to explain this requirement is to say that small predators will not control large pests, and large predators will eat many small pests. Most people find this is easy to understand but it does not seem to have become widely incorporated into pest management decision making.
Beware of 'pest monitoring' masquerading as integrated pest management! Until now, pest control actions have usually been based solely on the numbers of pests. For effective IPM, both the pests and beneficials need to be taken into account.
Based on the balances of pests and beneficials, decisions can be made on whether control actions are required. IPM consultants can help with decision making. Biological and cultural controls are used where possible, with strategic use of "soft" insecticides as a backup.
