Action Threshold Pest Management

Rather levels which pests will become an economic threat is critical pest control decisions.

Action threshold pest management. 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. The level at which pests will either become an economic threat is critical to guide future pest control decisions. 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. Insects are a vital part of the environment and overall play an important beneficial role.

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. The teacher doesn t know whether the beetle poses a problem but is concerned because of its size and appearance. Five yellowjackets at atrash can 10 percent feeding damage to a plant three flies in a classroom. 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.

Sometimes an action threshold is anumber. So just because a pest is present doesn t necessarily mean there is. 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 et is the practical rule used to determine when to take management 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. In simplest form action thresholds are rules that help the pest control technician know when a particular problem is serious enough to warrant control. In fact some refer to the et as the action threshold.

The important thing to remember here is that there is no such thing as an insect free landscape. Action thresholds help determine both the need for control actions and the proper timing of such actions. Monitor and identify pests. Sighting a single pest does not always mean control is needed.

Action thresholds are site specific and part of integrated pest management decisions. Sighting a single pest does not always mean control is needed. 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. 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.

Light orno infestationversus heavy infestation. 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. For example a teacher reports a ground beetle to the school office.

Below the threshold level the ipm. 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. How high or low this level is depends on how much damage can be tolerated which in turn varies depending on the situation.
