Field release in Florida of Diaphorencyrtus aligarhensis (Hymenoptera: Encyrtidae), an endoparasitoid of Diaphorina citri (Homoptera: Psyllidae), from mainland China
Florida Entomologist 95 (2), 479-481
Abstract: Despite the release of thousands of D. aligarhensis in 2000-2002 (Tawain population) (Skelley and Hoy 2004) and over 11,000 in 2007-2009 (mainland China population), in numerous counties throughout the citrus growing regions of Florida, D. aligarhenisis appears not to have established to date. Factors contributing to this apparent failure include intense pesticide use to control D. citri, low and variable populations of immature psyllids, competition with T. radiata, and predation of parasitized hosts by generalist predators. Nevertheless, the 2 parasitoids are known to co-exist in many parts of Asia, and further efforts to establish D. aligarhensis in Florida are still warranted.
