“…This fact could be explained by the fact that the HMO control of the spread of virus decreases when the viral inoculum pressure increases (Simons & Zitter, 1980;Umesh et al, 1995;Vidal et al, 2010). Therefore, the high CTV inoculum pressure present in the experimental nursery plot may explain the failure to reduce the CTV spread under the assayed conditions.…”

The control of Citrus tristeza virus (CTV), the causal agent of tristeza disease, is essential to guarantee a productive citrus industry. The specific features of a nursery block make the control of the natural spread of viruses transmitted by vectors more difficult. Thus, the knowledge of the epidemiology of CTV in nursery blocks is basic to the design control strategies of the disease. Two experimental nursery plots of alemow (Citrus macrophylla) were planted in open field in Moncada (Valencia, Spain) (with a high CTV prevalence, 85%), and in Alcanar (Tarragona, Spain) with 700 and 843 nursery plants, respectively. The plants were analysed by tissue print-ELISA using 3DF1 and 3CA5 CTVspecific monoclonal antibodies. The CTV prevalence estimated after one year of cultivation in both plots was of 24.37% and 3.91%, respectively. At the same time, a commercial nursery plot grown under plastic-net covers established in Alcanar with 1,200 plants was also analysed as above, being the CTV prevalence estimated of 0.00%. The aphid activity present in the nursery plots was monitored. Aphis spiraecola was the most abundant aphid species visiting the plants in the nursery plots grown in the open field, whereas the aphid activity registered in the plants grown under the plasticnet covers was practically zero. The percentage of individual aphids carrying CTV PCR-amplifiable targets detected by squash real-time RT-PCR in the open-field nursery plots was 17.5% in Moncada and 1.67% in Alcanar. No significant differences in the CTV prevalence between treated and non-treated plants with horticultural mineral oils were found in the area with the high CTV-inoculum pressure.Additional key words: alemow; horticultural mineral oil treatments; physical barriers; semi-persistent virus; squash real-time RT-PCR; tissue print-ELISA; vector intensity.

“…Several control techniques against cucurbit virus are used to influence the behaviour of the insect vector in an attempt to interfere with virus transmission, including the use of reflective mulches (Lecoq & Pitrat 1983;Brown et al 1993;, oil sprays (Simons & Zitter 1980), and floating row covers (Natwick & Durazo 1985;Perring et al 1989;Orozco et al 1994). The use of plastic mulches in agriculture continues to increase in high technology systems for the production of horticultural crops.…”

(1995) Effect of transparent mulch on insect populations, virus diseases, soil temperature, and yield of cantaloup in a tropical region, New Zealand Journal of Crop and Horticultural Science, 23:2, 199-204, DOI: 10.1080/01140671.1995.9513887 To link to this article: https://doi.org/10.1080/01140671.1995.9513887 New Zealand Journal of Crop and Horticultural Science, 1995, Vol. 23: 199-204 Abstract Transparent polyethylene mulch was tested for its efficacy in reducing insect populations, virus diseases, and increasing soil temperature and yield of cantaloup (Cucumis melo L.) in a tropical region. Transparent mulch reduced whitefly populations, aphids caught in yellow traps, and virus incidence, with respect to bare soil (control). Also, soil temperatures in the morning, midday, and afternoon were significantly increased in the transparent mulch. Cantaloup fruit yield was positively influenced by the mulched plot. The export-and national-quality fruit yield was 11-fold and two-fold higher, respectively in the mulched plot in relation to control. Total yield in the transparent mulch was 31.2 t/ha, whereas that in bare soil was 6.9 t.

“…I nsecticides in most cases do not offer effective protection against aphid-borne non-persistently transmitted plant viruses, even when effective against the vector (Simons and Zitter, 1980;Lowery et al, 1990). Winged aphids can transmit the virus to healthy plants in a few seconds or minutes (Raccah, 1986), but insecticides generally require several hours to act.…”

“…Winged aphids can transmit the virus to healthy plants in a few seconds or minutes (Raccah, 1986), but insecticides generally require several hours to act. Since Bradley et al (1962) first demonstrated that paraffin oils interfere with potato virus Y (PVY) inoculation by aphids, these products have frequently been cited as giving effective protection against diverse non-persistent viruses transmitted by diverse vectors (Bradley, 1963;1966;Bradley et al, 1962;Ferro et al, 1980;Loebenstein et al, 1964;1966;Lowery et al, 1990;Migliori et al, 1998;Nitzany, 1966;Powell, 1992;Qiu and Pirone, 1989;Simons and Zitter, 1980;Simons, 1982;Vandervecken, 1977;Walkey and Dance, 1979).…”
