Action Threshold Pest Management

The important thing to remember here is that there is no such thing as an insect free landscape.

Action threshold pest management. Monitor and identify pests. 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. Sometimes an action threshold is anumber. Rather levels which pests will become an economic threat is critical pest control decisions.

Light orno infestationversus heavy infestation. A single pest does not always need any control action. In an ipm strategy action thresholds help discern when action is necessary and when it isn t. 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.

Sighting a single pest does not always mean control is needed. For example a teacher reports a ground beetle to the school office. The action threshold is a point at which pest populations or environmental conditions show that you must take pest control action. 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.

So just because a pest is present doesn t necessarily mean there is. The teacher doesn t know whether the beetle poses a problem but is concerned because of its size and appearance. 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. How high or low this level is depends on how much damage can be tolerated which in turn varies depending on the situation.

Often uses action thresholds an action thresholdis the point at whichan ipmtechniciantakes action to reduce apest s numbers. It is essentially a prediction of when a pest population is going to reach the eil. The et is the practical rule used to determine when to take management action. 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.

In simplest form action thresholds are rules that help the pest control technician know when a particular problem is serious enough to warrant control. The level at which pests will either become an economic threat is critical to guide future pest control 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. Below the threshold level the ipm.

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. In fact some refer to the et as the action threshold. Sighting a single pest does not always mean control is needed.

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. Action thresholds are site specific and part of integrated pest management decisions. Action thresholds help determine both the need for control actions and the proper timing of such actions.
