Abstract
Field and laboratory studies were carried out to evaluate three eggplant cultivars, long black (Anan), white long (Soma) and spherical black (classic) for their relative susceptibility to spotted spider mite, Tetranychus urticae Koch, whitefly, Bemisia tabaci (Gennadius), aphid, Aphis gossypii Glover and Jassid, Empoasca lybica de-Berg infestation. The obtained results showed that spherical black cultivar was the most susceptible to spider mites, aphid and whitefly, while black cultivar was lowest level infestation by the tested sucking pests.Obtained data cleared that there were significant differences between eggplant cultivars and piercing sucking pests, which may be affected by plant leaf phytochemical constituents; total amino acids, total lipids, total carbohydrates, sodium, potassium, phosphorus, calcium, chloride and nitrogen, therefore, sodium, potassium, chloride, magnesium contents were negatively correlated with population density of different piercing sucking pests. On the other hand, total amino acids, lipids, carbohydrates, protein and nitrogen positively correlated with different piercing sucking pests.
