Research Project: Identification of Risk Factors Leading to Arrival and Establishment of Exotic Psyllids in North America

Location: Temperate Tree Fruit and Vegetable Research

Project Number: 2092-22000-021-36-S
Project Type: Non-Assistance Cooperative Agreement

Start Date: Aug 1, 2018
End Date: Jul 31, 2019

Objective:
Create and analyze large data base summarizing life history aspects, biogeography, and host relationships of approximately 200 psyllid species, for use in defining traits that lead to establishment of exotic psyllids in North America.

Approach:
A survey of the primary literature and other sources will be used to provide information on distribution, geographic origin, host use, assumed year-of-arrival, and spread of exotic psyllids currently established in North America. That overview will be followed by constructing a detailed synthesis of life history data, host association data, and native geographic ranges of ca. 200 non-exotic psyllid species from outside of North America, for which good life history data exist. These data will be used as a biological snapshot of a typical “control” (non-exotic) psyllid, against which our exotic psyllids will be compared. The USDA cooperator will use multivariate ordination to compare traits for exotic psyllids to our snapshot of control psyllids as a means to identify psyllid biological traits or biogeographic regions that are overrepresented in exotic psyllids relative to what is seen for non-exotic species.
