The Asian citrus psyllid, Diaphorina citri (Kuwayama) is the vector of Huanglongbing, the most serious disease of citrus worldwide (Bové 2006). Although most psyllids, including D. citri, confine breeding to a narrow range of usually related host plants, the adults will feed and obtain nutrition from a wider array of plants (Hodkinson 1974). The Asian citrus psyllid prefers Citrus spp. and all breeding host plants are in the family Rutaceae (reviewed by Halbert & Manjunath 2004). Feeding could spread the disease agent to non-citrus plants that might then serve as reservoirs of the disease in nature. A mitigating factor is that only the immature stages of the psyllid can effectively acquire and host the bacteria (Pelz-Stelinski et al. 2010), and thus, any plant species that serve as breeding hosts are of primary concern in that regard. On 23 Jul 2010 while surveying dooryard citrus trees for infestations of D. citri, we noted that adults of this insect were abundant on a fig tree, Ficus carica (L.) adjacent (~2m) to a heavily infested key lime tree, Citrus limon (L.) (Fig. 1). On further inspection we noted immature psyllids, including fifth instars, on the new flush of this fig tree. A second fig tree on the same property was not infested, possibly because it was not in flush. Some of the nymphs were brought to the laboratory where we confirmed their identity as D. citri. There are at least 7 genera of psyllids, most in the tribe Homotomini, known to infest Ficus spp. in the Old World with a record of one species, Homotoma ficus (L.) infesting figs in California in 1969. Nymphs of the Asian citrus psyllid can be distinguished from all of these by its 3 segmented antenna, narrow lateral thoracic sclerites, and a se-
