Plain language summary
The feeding damage of aphids and their ability to transmit plant diseases causes billion of dollars annually to world agricultural crops. It is critical that proper identification be established before any control program can start. This work updates previous lists of invasive (and adventive) aphids for North America North of Mexico, and includes important information such as location, date of the aphids' first discovery, its biogeographic origin, and economically important North America hosts. This information on species clarification is invaluable for plant quarantine inspectors, provincial and federal identifiers, invasive species specialists and aphid systematists.
Abstract
Two hundred and sixty-two adventive aphids (Hemiptera: Aphidoidea) have been previously reported in North America north of Mexico. We update this to include 25 previously unrecorded species, and include information on the location and date of first discovery, biogeographic origin, and economically important North American hosts for these species. The number of adventive species introduced per year has decreased overall since 1930.We discuss aphids intercepted at United States ports of entry and identified by the Systematic Entomology Laboratory from 2000–2016 and comment on how the composition of species intercepted may affect the adventive species that become established.
