Abstract Seasonal abundance of the Asian citrus psyllid, Diaphorina citri Kuwayama, was studied weekly in two orange jasmine [Murraya paniculata (L.) Jack] plots in southern Florida from October 1998 to October 1999. Psyllid populations occur throughout the season on orange jasmine in southern Florida. Population peaks were observed in October, November, and December in 1998, and May and August in 1999. Psyllid population levels were positively related to the availability of new shoot flushes which were in turn related to the weekly minimum temperature and rainfall. Natural enemies were not key factors in regulating populations during the study period. The populations of adult psyllids were also studied weekly on potted orange jasmine and grapefruit (Citrus paradisi Macfadyen) plants from June 1999 to July 2000. The population levels of psyllid on both host plants were not significantly different and general population trends on the two hosts were similar over time. Continuous shoot flushes produced by orange jasmine could play an important role in maintaining high populations of this insect when new shoot flushes were not available in the commercial citrus groves.

Exclusion techniques reveal significant biotic mortality suffered by Asian citrus psyllid Diaphorina citri (Hemiptera: Psyllidae) populations in Florida citrus (2009, background): “Tsai et al. (2002) and Michaud (2004) reported only 1–2% parasitism by Tamarixia radiata (Waterston), an ectoparasitoid of D. citri nymphs imported from Taiwan and south Vietnam, and released in Florida to improve the biological control of D. citri (Hoy et al., 1999).”
Biology and management of Asian citrus psyllid, vector of the huanglongbing pathogens. (2013, background): “(151), Michaud (94), and Qureshi & Stansly (113) reported only 1–3% parasitism from T.”
Integrated approaches for managing the Asian citrus psyllid Diaphorina citri (Homoptera: Psyllidae) in Florida (2007, background): “It has now spread to almost all the citrus growing regions of the state (Halbert and Manjunath, 2004; Michaud, 2002; Tsai et al., 2002) and has also been identifi ed in Texas (French et al., 2001).”
Dormant season foliar sprays of broad-spectrum insecticides: an effective component of integrated management for Diaphorina citri (Hemiptera: Psyllidae) in citrus orchards. (2010, background): “Adults can also feed and survive on the fully developed leaves for several months (Tsai et al., 2002; Qureshi and Stansly, 2008).”
