The role of specific tomato volatiles in tomato-whitefly interaction.
Bemisia tabaci (whitefly) infestations and the subsequent transfer of viruses are the cause of severe losses in crop production and horticultural practice. To improve biological control of B. tabaci, we investigated repellent properties of plant-produced semiochemicals. The mix of headspace volatiles, collected from naturally repellent wild tomato accessions, influenced B. tabaci initial choice...
متن کاملTYLCV-resistant Tomato Cultivar Trial and Whitefly Control Strategies
Tomato yellow leaf curl virus (TYLCV) and tomato spotted wilt virus (TSWV) are common diseases of tomato in Florida. TYLCV occurs in central and southern Florida whereas TSWV occurs in northern Florida and throughout all states of the southeastern USA. TYLCVresistant cultivars and advanced breeder’s varieties are available for commercial use, but vegetable producers don’t often use them. A vari...
متن کاملSelection of processing tomato genotypes with high acyl sugar content that are resistant to the tomato pinworm.
Acyl sugars are allelochemicals present at high concentrations in leaves of accessions of the wild tomato Solanum pennellii; they confer resistance to a large number of arthropod pests, including the tomato pinworm, Tuta absoluta (Lepidoptera, Gelechiidae). Accession 'LA716', with high contents of acyl sugars in the leaves, was used as a source of resistance to start a genetic breeding program ...
متن کاملInsecticidal Effects of Selected Soaps, Oils and Detergents on the Sweetpotato Whitefly: (Homoptera: Aleyrodidae)
Efficacy against the sweetpotato whitefly (SPWF) Bemisia tabaci (Gennadius) of an insecticidal soap, two horticultural oils (one vegetable and the other petroleum based) and 15 detergents was evaluated under greenhouse conditions. Applications were directed to the underside of infested zucchini squash, tomato, or poinsettia leaves. Live nymphs were distinguished by their ability to deposit hone...
متن کاملThe Large-scale Isolation of Protoplasts from Immature Tomato Fruit
It has long been realised that the study of isolated protoplasts offers a potentially new approach to problems of plant cell biology. For this potential to be fully realised, intact protoplasts must be produced, free from contamination by cell debris, on a scale sufficiently large to enable biochemical and physiological experiments to be performed. This aim, though not impossible as has been su...
