Despite the substantial impacts of nonindigenous plant pests and weeds, relatively little is known about the pathways by which these organisms arrive in the U.S. One source of such information is the Port Information Network (PIN) database, maintained by the U.S. Department of Agriculture, Animal and Plant Health Inspection Service (APHIS) since 1984. The PIN database is comprised of records of pests intercepted by APHIS personnel during inspections of travelers’ baggage, cargo, conveyances and… 

Worldwide border interceptions provide a window into human-mediated global insect movement.

This work gathered insect interception data from nine world regions collected from 1995 - 2019 to compare the composition of species arriving at ports in these regions and found strong positive correlations in species interception frequencies between regions, particularly within the Hemiptera and Thysanoptera.

Transportation of nonindigenous species via soil on international aircraft passengers’ footwear

Survey of organisms present in soil that had been removed from footwear being carried in the baggage of international aircraft passengers arriving in New Zealand recorded high incidences, counts and diversities of viable bacteria, fungi, nematodes and seeds, as well as several live arthropods that were almost certainly nonindigenous to this country.

Historical Accumulation of Nonindigenous Forest Pests in the Continental United States

A comprehensive species list to assess the accumulation rates of nonindigenous forest insects and pathogens established in the United States found sap feeders and foliage feeders dominated the comprehensive list, but phloem- and wood-boring insects and foliageFeeders were often more damaging than expected.

Interceptações de pragas quarentenárias e ausentes não regulamentadas em material vegetal importado

Of the intercepted pests species, 63% are not regulated as quarantine pests for Brazil, and these results indicate the urgent need to review the current list of quarantine pests in the country.

Pest interceptions on imported fresh fruits into South Africa

There is an urgent need for the revision of the current phytosanitary policies and border controls to intensify reduction in the future introduced alien invasive species.

Entry of exotic insects into Australia: Does border interception count match incursion risk?

Interception data collected at the Australian quarantine border on the orders Coleoptera, Hemiptera, Lepidoptera and Diptera during 1986–2005 were cross-referenced to incursion data, supporting the argument that propagule pressure is a key factor in invasion establishment.

Tentative analysis of the interceptions of non-indigenous organisms in Europe during 1995-2004

The discrepancies observed for some species between a limited number of interceptions and their effective establishment in Europe (e.g. only 1 interception for the western corn rootworm, Diabrotica virgifera) could be useful for identifying the invasion pathways.

Gaps in Border Controls Are Related to Quarantine Alien Insect Invasions in Europe

A method to quantify the volume of agricultural trade that should be inspected for quarantine insects at border control points in Europe, based on global agricultural trade of over 100 million distinct origin-commodity-species-destination pathways, was developed and used to evaluate the performance of existing border controls.

Quarantine supervision of Wood Packaging Materials (WPM) at Chinese ports of entry from 2003 to 2016.

The number of pest disposal treatment measures for intercepted cargoes with dead non-quarantine pests increased significantly from 2012 to 2016, which reflects the fact that Chinese customs inspection stations are becoming increasingly scientific and standardizing the interception and treatment of WPM pests.

Live plant imports: the major pathway for forest insect and pathogen invasions of the US

Two data sources were used to estimate the infestation rate of regulated pests in live plant shipments entering the US, thus allowing evaluation of the efficacy of the current port inspection process.



Intercepted Scolytidae (Coleoptera) at U.S. ports of Entry: 1985–2000

The scolytids were intercepted from 117 different countries; the top 12 countries were Italy (1090 interceptions), Germany (756), Spain (457), Mexico (425), Jamaica (398), Belgium (352), France (261), China (255), Russia (247), India (224), U.K. (151), and Portugal (150).

Airline Baggage as a Pathway for Alien Insect Species Invading the United States

Invasions by non-indigenous species are a problem of increasing magnitude and threaten the stability of the world's ecosystems and economies. Despite the enormity of this problem, relatively little

Invasion by Exotic Forest Pests: A Threat to Forest Ecosystems

This work presents case histories that illustrate the invasion process via details of the arrival, spread, impact, and management of selected exotic forest pests.

Invasion of North American Forests by European Phytophagous Insects Legacy of the European crucible

Questions about managing these introduced insect species and concern about continued importation of new ones are timely because of the past severe and everspreading impacts of introduced insect pests on North American forest ecosystems.

Invasion Pathways of Karnal Bunt of Wheat into the United States.

The results indicate that Karnal bunt has probably arrived in the United States on many occasions, at least since 1984, and it is possible this disease has a long period of latent survival between initial arrival and becoming a thriving, established disease.

Environmental and Economic Costs of Nonindigenous Species in the United States

Aproximately 50,000 nonindigenous (non-native) species are estimated to have been introduced to the United States, many of which are beneficial but have caused major economic losses in agriculture, forestry, and several other segments of the US economy, in addition to harming the environment.

Pest risk assessment of insects in sea cargo containers

The survey collection of dead insects demonstrates that containers are regularly exposed to economically important quarantinable insects, including timber pests, agricultural pests, and nuisance pests (vespids and Solenopsis sp.).

Exclusion as a Plant Disease Control Strategy

Assistance to exporters of plant products such as fruits, vegetables, plants, cut flowers, commodities, etc, in meeting the quarantine or exclusion requirements of importing countries and, therefor, bascd on plant health, biologically facilitating the acceptancc of exports.

The population biology of invaders

Analysis of invasions by insects released as biocontrol agents against weeds, show that the probability of successful establishment is closely related to the insect's intrinsic rate of increase, and a general model for the dynamics of an invading species is proposed.


Biologists are nearly unanimous in their belief that humanity is in the process of extirpating a significant portion of the earth's spe­ cies. The ways in which we are doing so reflect the magnitude
