Details on the situation of Bactrocera latifrons, D. undecimpuntata howardi, Diabrotica virgifera virgifera and Rhagoletis cingulata in the USA
The Web site of NAPIS (National Agricultural Pest Information System – USA) provides detailed information on the geographical distribution of some pests, and shows maps resulting from surveys carried out in USA. The EPPO Secretariat has extracted the following new detailed geographical data:
Bactrocera latifrons: California (isolated foci in Los Angeles county). It is noted that California has reported a first find (dated 1998-07-21) but without any further detail.
Diabrotica undecimpunctata howardi (EPPO A1 quarantine pest): Alabama, Arizona, Arkansas, Colorado, Connecticut, Delaware, Florida, Georgia*, Illinois, Indiana, Iowa, Kansas, Kentucky, Louisiana, Maine, Maryland, Massachusetts, Michigan, Minnesota, Mississippi, Missouri, Nebraska, New Jersey, New Hampshire, New Mexico, New York, North Carolina, Ohio, Oklahoma, Pennsylvania, Rhode Island, South Carolina, South Dakota, Tennessee, Texas, Utah, Vermont, Virginia, West Virginia, Wisconsin, Wyoming.

* The NAPIS map had no data for Georgia, but from the literature, it appears that the pest is present there (e.g. a reference from Buntin, G.D.; All, J.N.; McCracken, D.V.; Hargrove, W.L. (1994) Cover crop and nitrogen fertility effects on southern corn rootworm (Coleoptera: Chrysomelidae) damage in corn. Journal of Economic Entomology, 87(6), 1683-1688.)
