Chemical control and management approaches of the Asian citrus psyllid, Diaphorina citri kuwayama (Homoptera: psyllidae) in Florida citrus

Carl C. Childers, Michael E. Rogers


The Asian citrus psyllid [Diaphorina citri Kuwayama (Homoptera: Psyllidae)] is a serious pest of Florida citrus, especially on young trees being brought to early production. Adults overwinter on both mature and young citrus leaf flush whereas the nymphs develop only on new flush. The insect attacks new growth and females deposit eggs on this newly expanding flush with subsequent establishment of nymphal colonies. The biology of this insect pest is reviewed along with damage produced as a result of feeding injury by both adult and nymphal stages. Methods of assessment of various insecticides for controlling both Asian citrus psylla adults and nymphs are presented from research conducted on Florida citrus since 2001. Management approaches using chemical control for psyllid on Florida citrus are discussed.
