The complete picture of long-term ecological effects from invasive pests is difficult to measure; and it is too early to determine the effects of the many new invasive pest introductions. Much of the research has focused of the biology of the pests—i.e. life cycle and host preferences—towards understanding how to contain their spread. [10]
In a pest risk analysis initiated by a specific pathway, often an imported commodity or goods associated with an imported commodity, e.g. packing materials, the probability of pest entry is evaluated for that specific pathway. For a pest risk analysis initiated for a specific pest, all probable pathways are evaluated for that individual pest.
PPQ aims to support APHIS goals by early detection of pests, weeds and plant diseases harmful to the economy, to allow for an organized response before significant damage is caused. The National Identification Services (NIS) coordinates reports of plant pest identification, providing a database that may lead to quarantine actions.
Pest control is the regulation or management of a species defined as a pest; such as any animal, plant or fungus that impacts adversely on human activities or environment. [1] The human response depends on the importance of the damage done and will range from tolerance, through deterrence and management, to attempts to completely eradicate the ...
Crop scouting is an Integrated pest management strategy that looks at many different aspects of crop production, not just any single pest or problem. [3] Scouts must be actively observing environmental conditions, beneficial insects , pest insects, diseases, weeds , crop growth stage, and the general health of the crop in question to get a ...

[1] It relies on predation, parasitism, herbivory, or other natural mechanisms, but typically also involves an active human management role.
