“…A related disease was recorded in peach ( Prunus persica ) in 1890 in the USA, with outbreaks (mainly in Georgia) in 1929, 1951, and 1976; this was named phony peach disease (PPD). The causal agent of PD was isolated from grapes in a pure culture for the first time in 1978 ( Davis et al, 1978 , Turner and Pollard, 1955 , Turner and Pollard, 1959 ). Now, 125 years later, PD is still a significant concern for grape and wine producers in the southern USA (especially California, Texas, and Florida), and the affected plants account for 150 species and innumerable cultivars.…”

“…Thanks to the xylematic conductor system, the water and mineral salts contained in the soil can reach the active photosynthesizing tissues, mainly present in the leaves. The known vegetal host range of the bacterium is vast, including more than 100 plant species ( Turner and Pollard, 1955 , Turner and Pollard, 1959 ). Preferred plants depend on the season and locality, but, in general, the preferred species include crape myrtle, citrus, and holly.…”

“…It should be recognized that although many leafhoppers may carry X. fastidiosa, they are not equally efficient in trans- mission. Successful transmission is driven by several factors, including their affinity for the host, seasonal host susceptibility, and the vector's feeding habits (Day and Bennetts 1954;Turner and Pollard 1955;Purcell 1979). Determining the vectors is essential in understanding the epidemiology of BLS.…”

Xylella fastidiosa has been recognized as a pathogen of landscape trees for over 25 years. Collectively, these diseases are referred to as bacterial leaf scorch (BLS). Arborists, property owners, and communities are now beginning to recognize BLS as a serious threat to the urban forest. Although advances in symptom awareness and diagnostic techniques have enabled arborists to diagnose BLS, there are many questions regarding host range, transmission, pathogeneses, disease management, and individual tree therapy that remain unanswered.

“…Oleander leaf scorch was Þrst noticed in California at Palm Springs (Riverside County) and Tustin (Orange County) in 1994, whereas PierceÕs disease associated with H. coagulata was Þrst noticed in Temecula (Riverside County) in 1997 (Blua et al 1999). The potential of H. coagulata to spread other plant diseases induced by X. fastidiosa is well documented in the southeastern United States where this insect is a native (Turner and Pollard 1955). H. lacerta is native to California and is abundant in the dryer areas of the southern part of the state (Young 1958).…”

Homalodisca coagulata (Say) and Homalodisca lacerta (Fowler) are vectors of a new bacterial disease of oleander in California known as oleander leaf scorch, induced by the bacterium Xylella fastidiosa. H. coagulata also has been implicated in the spread of the strain of X. fastidiosa that induces Pierce's disease of grapevines in California. We monitored the flight activity of H. coagulata and H. lacerta in oleander and citrus by using yellow sticky cards at three southern California locations where outbreaks of oleander leaf scorch have been documented, and where vector compliments are different. Areas sampled included a mesic coastal area (Irvine, CA) that supports predominantly H. coagulata and few H. lacerta, a dry inland location (Palm Desert, CA) that supports predominantly H. lacerta and few H. coagulata, and an intermediate area (Riverside, CA) supporting both Homalodisca species. From November 1996 to October 1999 peak catches of both Homalodisca species occurred during the midsummer at all locations. H. coagulata was trapped in greater numbers in citrus than in oleander at both the Riverside and the Irvine sites. Likewise, H. lacerta in Riverside was more associated with citrus than oleander, yet H. lacerta in Palm Desert was trapped in greater numbers in oleander than citrus.
