Details on the geographical distribution of Nacobbus aberrans in USA
In United States, Nacobbus aberrans (EPPO A1 quarantine pest) is reported on sugarbeet (Beta vulgaris) in the following states: Colorado, Kansas*, Nebraska*, Montana*, South Dakota*, Utah* and Wyoming. In Nebraska, crop losses of 10-20 % occur in sugar beet fields infested by N. aberrans. In Arkansas*, N. aberrans was found on tomato (Lycopersicon esculentum) and rose (Rosa sp.). Another species of minor economic importance, Nacobbus dorsalis, has been found only in California on weeds and sugar beet.
