Though the first light brown apple moth confirmed in California by DNA analysis was found in February 2007, scientists like James Carey, a professor of entomology at the University of California-Davis and associate editor on several journals, believes, based on his previous experience with the gypsy moth program, that the light brown apple moth has likely lived in California for years and possibly decades (in part because it is so widespread, from Los Angeles to north of San Francisco).[5][6] The debate over how long the moth has been in the state has not yet been resolved. Questions about the rationale for the timing of the spray program suggest that it appears be more closely related to agricultural quarantines from Mexico and Canada than other factors.[7]
