Biological control of Asian citrus psyllid, Diaphorina citri (Hemiptera: Psyllidae) in Florida: A preliminary report
Entomological News 113 (3), 216-222
Abstract: The Asian citrus psyllid, Diaphorina citri, recently invaded the citrus-producing regions of Florida, reaching the northern limits of commercial production in summer of 2001. Preliminary observations indicate a wide range of natural enemies attacking juvenile stages of D. citri. The exotic parasitoid Tamarixia radiata (Hymenoptera: Eulophidae) was released in previous years and has established, but is not a significant source of mortality for D. citri at present. The primary sources of mortality for juvenile psyllids are two coccinellid species, Olla v-nigrum and Harmonia axyridis. Both species complete development successfully on an exclusive diet of D. citri. Other ladybeetles completing development on D. citri include Curinus coeruleus, Cycloneda sanguinea, and Exochomus childreni childreni. Other predators observed attacking D. citri in Florida include hunting spiders (Aranae: Anyphaenidae, Clubionidae, Oxyopidae, and Salticidae), lacewings (Neuroptera: Chrysopidae, Hemerobiidae), hoverflies (Diptera: Syrphidae), and predatory bugs (Hemiptera: Anthocoridae).
