“…Although ten aphid species were recorded on citrus from different regions of India (Chakrabarti and Sarkar, 2001;Raychaudhuri et al, 1983), occurrence of B. helichrysi in citrus has been reported for the first time in this study. All the aphid species except B. helichrysi are observed to transmit CTV in the present study, substantiated by earlier reports of Costa and Grant (1951), Norman and Grant (1956), Varma et al (1960), Sasaki (1974), Ahlawat and Raychaudhuri (1988).…”

“…Only five of these viz. Toxoptera citricida, Toxoptera aurantii, Aphis gossypii, Aphis spiraecola and Myzus persicae are important having ability to transmit different strains of citrus tristeza virus (CTV) in a semi-persistent manner (Ahlawat and Raychaudhuri, 1988;Costa and Grant, 1951;Norman and Grant, 1956;Sasaki, 1974;Varma et al, 1960). CTV is now widespread in this region causing severe loss in production (Ghosh et al, 2014;Mukhopadhyay et al, 1986).…”

“…On the other hand, transmission by the melon aphid, Aphis gossypii varied considerably on different occasions (19,48,49,86,124,124,127,138,144). Different populations of A. gossypii did not vary significantly in their ability to transmit CTV (14, 125,126) nor did the hosts used to rear aphids prior to transmission significantly influence the CTV transmission rate obtained with T. citricida (44) or A. gossypii (14).…”

INTRODUCTIONCitrus tristeza virus (CTV) (132), an aphid-borne closterovirus (10), has ranked as one of the most important citrus diseases for the last sixty years.CTV epidemics have caused the severe decline or death of millions of trees in many areas where the sour orange (Citrus aurantium) was used as a rootstock.In other areas, the productivity of grapefruit and certain sweet orange varieties was considerably affected by CTV strains causing stem pitting decline.Unlike certain other disease agents, e.g. Spiroplasma citri (180) and Phoma tracheiphilla (93), which became associated with citrus during the acclimatization of this crop in the Near East, CTV was probably present from antiquity in citrus cultivated in China and Japan. However, CTV was not transported with its hosts, mainly because early acclimatization of citrus was from seed sources and CTV is not seed-transmitted (106). In retrospect, the tristeza disease in most citrus growing areas was a man-made problem created by the desire of horticulturists to introduce varieties from other citrus growing areas. 291 0066-4286/89/0901-0291$02.00 Annu.

Comparative transmission tests sug gested that the incompatibility problems in South Africa and Australia, the root problem in Brazil, and the quick decline in California were all man ifestations of the same disease (81). Other syndromes associated with CTV infection have been described, of which the most important is probably stem pitting (sp) decline (46,110,114,115,120,152,154,184) and seedling yellows (34, 63,107,141,180). Synonyms of CTV include Hassaku dwarf (164) and Natsudaidai dwarf (121). THE HOST RANGE OF CTVCTV infects most citrus species, varieties, hybrids and some citrus relatives such as Aeglopsis chevalieri Swing., Afraegle paniculata (Schum.) Engl., and Pamburus missiones (Wt.) Swing. (180). The only known hosts outside the Rutaceae are certain species of Passiflora (118, 145). Attempts to transmit CTV to non-Rutaceae species, either by aphids (145) and/or by mechanical inoculation (119), were unsuccessful. The reaction of different citrus species, hybrids, and citrus relatives to CTV infection varies considerably. Some plants, such as Poncirus trifoliata (L.) Raj., some hybrids between P. trifo tiata and sweet orange (Citrus sinensis (L.) Osb.) or grapefruits (c. paradisi), Severinia buxifolia, and Swinglea glutinosa (68), arc resistant to CTV and usually do not support detectable multiplication of the virus. Occasionally P. trifoliata or its hybrids were found to show CTV symptoms (35), although the virus was not verified as the causal agent in all trifoliate infection. In other...

“…The three strains of tristeza virus used in these studies have been previously described (4,5 ) . Sources of inoculum for the mild strain (TI and T,) were Temple orange seedlings selected for uniformity and inoculated by means of leaf pieces from aphid-infected Key lime test plants.…”

Variations in Aphid Transmission o f Tristeza VirusVanr*noN in efficiency of aphids as vectors of tristeza virus has been noted among species reported as vectors in different infected areas. The brown citrus aphid [Toxoptera citricidus (Kirk.)] is considered an efficient vector in certain areas ( I ) , but is not known to be present in the United States. The melon aphid [Aphis gossypii (Glov.)] was shown by Dickson to transmit quick-decline (tristeza) virus in California, but was judged to be an inefficient vector ( 2 ) . Tests in Florida (4,5) have shown
