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]
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.
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.
Biological control or biocontrol is a method of controlling pests, whether pest animals such as insects and mites, weeds, or pathogens affecting animals or plants by using other organisms. [1] It relies on predation, parasitism, herbivory, or other natural mechanisms, but typically also involves an active human management role.
