Asian Citrus Psyllid
Asian Citrus Psyllid
The Asian citrus psyllid (ACP), Diaphorina citri Kuwayama, a tiny, mottled-brown insect about the size of an aphid, poses a serious threat to California’s citrus trees, including those grown in home gardens and on farms. The psyllid feeds on all varieties of citrus (e.g. oranges, grapefruit, lemons, and mandarins) and a few very closely related ornamental plants in the family Rutaceae (e.g. calamondin, box orange, Indian curry leaf, and orange jessamine or orange jasmine).
