Action Threshold Pest Management

Management guidelines for a particular insect pest include a population density usually referred to as the action threshold that is used to determine if a control tactic is justified.

Action threshold pest management.

If pest populations threaten plant health become a nuisance or aesthetically intolerable the action threshold may have been exceeded and suppression tactics should be implemented by using ipm practices either alone or in combination. Action thresholds help determine both the need for control actions and the proper timing of such actions. The teacher doesn t know whether the beetle poses a problem but is concerned because of its size and appearance. In an ipm strategy action thresholds help discern when action is necessary and when it isn t.

For example a teacher reports a ground beetle to the school office. The number of pests and level of damage beyond which treatment should be taken is known as the treatment threshold a fundamental concept in integrated pest management. It is essentially a prediction of when a pest population is going to reach the eil. As long as the pest density remains below this threshold no action is needed but if the insect population density exceeds this level a control action is recommended.

The technician refers to the school s pest management notebook and determines that the beetle is not a health threat and that thresholds for treatment occur. Light orno infestationversus heavy infestation. Rather levels which pests will become an economic threat is critical pest control decisions. Five yellowjackets at atrash can 10 percent feeding damage to a plant three flies in a classroom.

Setting action thresholds in integrated pest management integrated pest management ipm refers to a specific strategy of pest management that seeks to minimize both the frequency and invasiveness of pest control intervention. Action threshold means the point at which pest populations or environmental conditions can no longer be tolerated necessitating that pest control action be taken based on economic human health aesthetic or other effects. Insects are a vital part of the environment and overall play an important beneficial role. The action threshold is a point at which pest populations or environmental conditions show that you must take pest control action.

The et is the practical rule used to determine when to take management action. The level at which pests will either become an economic threat is critical to guide future pest control decisions. Action thresholds are site specific and part of integrated pest management decisions. Before taking any pest control action ipm first sets an action threshold a point at which pest populations or environmental conditions indicate that pest control action must be taken.

In simplest form action thresholds are rules that help the pest control technician know when a particular problem is serious enough to warrant control. It is assumed that once the et is reached there is a high probability that the pest population will reach the eil if no management action is taken. Sighting a single pest does not always mean control is needed. A single pest does not always need any control action.

Monitor and identify pests. Below the threshold level the ipm. Sometimes an action threshold is anumber. Sighting a single pest does not always mean control is needed.

The presence of a few pest insect or mites and some amount of damage usually can be tolerated. The important thing to remember here is that there is no such thing as an insect free landscape. Often uses action thresholds an action thresholdis the point at whichan ipmtechniciantakes action to reduce apest s numbers.
