“…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...

“…Acquisition-and infection-feeding periods of less than four to six hours gave only low transmission rates, although some transmissions were obtained even at durations of one half to one hour (table I). Toxoptera citricidus needs only seconds t o transmit tristeza virus (Retuerma and Price, 1972), as is typical for stylet-borne viruses, whereas transmission by A. gossypii of VT, as well as of other strains (Norman et al, 1968), requires much longer periods for acquisition and infection (one half to one hour), which is characteristic for a semipersistent mode of transmission.…”

“…En los últimos años este áfido ha sido detectado en el Norte de España y Portugal (Ilharco et al, 2005), lo que supone una amenaza para la citricultura de la cuenca del Mediterráneo. El segundo vector más eficiente es Aphis gossyppi (Norman et al, 1968;Bar-Joseph y Loebenstein, 1973;Raccah y Singer, 1987;Hermoso de Mendoza et al, 1988a, b;Yokomi et al, 1989), que es el más importante en Norteamérica y la cuenca del Mediterráneo. Otras especies de pulgones como A. spiraecola y T. aurantii son menos eficientes (Hermoso de Mendoza et al,1984;Yokomi y Garnsey, 1987), pero al tener poblaciones más numerosas que A. gossyppi, pueden tener un papel en la dispersión de CTV en algunas zonas (Hermoso de Mendoza et al,1984).…”
