Florida citrus hosts a wide array of arthropod pests including insects, mites and nematodes. These pests can cause damage to citrus through their feeding on fruit, foliage and roots. Indirectly, feeding wounds can serve as an entry point for plant pathogens. Some pests may also act as vectors of plant diseases such as the Asian citrus psyllid (Diaphorina citri) which spreads the citrus greening pathogen Candidatus Liberibacter asiaticus. Florida citrus also has numerous beneficial species that help to maintain most potential pests below economically damaging levels.
