Citrus, belonging to the genus Citrus of the family Rutaceae, is the most widely produced fruit tree, and it is grown in more than 80 countries (Ladaniya, 2008).

A total of 526 dooryard, 18 varietal block, and 784 commercial citrus trees representing at least 18 species in the genus Citrus which were sampled including the following genera: Citrus Fortunella (kumquats) and Poncirus (Trifoliate orange) were sampled in 17 central and southern Florida counties between May 2009 and Apr 2014 (Table 1).

citri vector lives on all species of the genus Citrus and can be detected on other species of the family Rutaceae (Halbert & Manjunah 2004).
