In: Mansoura University Journal of Plant Protection and Pathology 2015.v.6(3)Summary: Field experiments were carried out to investigate the seasonal abundance and population dynamics of certain tomato pests viz.; tomato whitefly, Bemisia tabaci (Gennadius), aphids (cotton aphid, Aphis gossypii Glover and green peach aphid, Myzus persicae SUlzer), potato leafhopper, Empoasca decipiens Paoli and tomato leafminer, Tufa absoluta (Meyrick) and evaluate the susceptibility of two tomato cultivars (Hybrid Super Strain BF1 and Super Crystal HYB) to the infestation with these pests as a major component of the integrated pest management in clean and organic agriculture that rationalize -the unwise use of pesticides and accordingly producing safe food. Obtained results revealed that B. tabaci had 2-3 peaks of abundance during summer seasons 2012 & 2013 on both cultivars. Aphids and E. decipiens had 1-2 peaks each season. On the other hand, T. absoluta had only one peak during both seasons. Data also revealed the presence of negative and highly significant correlation between the population densities of all investigated pests and the numbers of non-glandular hairs on tomato leaves. Keywords: Bemisia tabaci, Aphis gossypii, Empoasca decipiens, Tufa absoluta, seasonal abundance, susceptibility, trichomes, nutrients.
