متن کاملPatterns of insecticide resistance in onion thrips (Thysanoptera: Thripidae) in onion fields in New York.
To develop an insecticide resistance management program for onion thrips, Thrips tabaci Lindeman (Thysanoptera: Thripidae), on onions (Allium spp.), we surveyed populations in commercial onion fields in New York and evaluated their susceptibility to the two most widely used classes of insecticides plus two new insecticides during 2003-2005.
