Abstract: McClean and Oberholzer (1965a) described the greening disease of citrus from South Africa and produced evidence to show that it is caused by a transmissible virus. A similar disease affecting sweet-orange (mosambi) was observed by the senior author in Andhra Pradesh in 1960 and was transmitted by grafting to greenhouse raised healthy seedlings of sweet-orange [Citrus sinensis (L.) Osbeck], Rangpur lime (limao cravo; C. limonia Osbeck), Indian acid-lime [kagzi nimbu; C. aurantifolia (Christm.) Swingle], and grapefruit (C. paradisi Maef.) cultivar ' Marsh Seedless' at Poona (Capoor, 1966). The identity of the disease and its similarity to the greening disease of South Africa was confirmed in 1966 (Fraser and Singh, 1966; Fraser et al., 1966). Schneider (1966) observed a necrosis of sieve tubes in leaves and in fruits of sweet-orange affected by the greening virus. Large amounts of phloem formed in the leaf veins as a result of the necrosis and caused the veins to be enlarged. The studies reported in the present paper deal with the transmISSIOn of the greening virus by the adults of Diaphorina citri Kuway., the species of psyllid commonly found on citrus in the country. The insect transmission tests were conducted during June-November 1966, when the population of citrus psylla is usually high on citrus trees in the central and southern India. Diaphorina citri is yet another species of psyllid responsible for the spread of the greening virus (Capoor et al., 1966), since the South African greening virus is spread by a psylla, Trioza (Spanioza) erytreae del Guercio (McClean and Oberholzer, 1965b).
