Arborist b 480-969-8808Citrus chlorotic dwarf virus


Scientific Name

[possible viral aetiology] Citrus chlorotic dwarf virus (CCDV).

Other common names 

Citrus chlorotic dwarf, citrus chlorotic dwarf disease (CCDD).



Disease cycle 

Vectored by bayberry whitefly (Parabemisia myricae (Kuwana)). It is transmissible by grafting on infected buds, slash inoculation from extracts of infected leaves and bark in phosphate buffer.

Citrus whitefly

Bayberry whitefly was first discovered in the U.S. by California agriculture officials in 1978, and in Florida by agriculture officials in early 1984. Early dense populations caused defoliation in California citrus (M. Rose, pers. comm.), but this has not happened in Florida. The early finds in Florida were under natural biological control by hymenopterous parasites, including Eretmocerus sp. Apparently, the parasites were introduced with the whitefly. According to Mike Rose (pers. comm.) the Eretmocerus species present in Florida is the same as that found in California.




Field symptoms consist of chlorotic flecking on young leaves, warping, crinkling, inverted cupping, spoon-shaping and variegation on leaves. Strong chlorosis and dwarfing of leaves are also observed. Grapefruit, lemon, mandarin and sour orange develop more severe symptoms than sweet orange. Diagnosis is made by grafting on rough lemon and Citrus macrophylla preferably in warm conditions
