“…JiRong et al (2011) reported that the hairy tomato plants can repel aphids, B. tabaci and American leaf miner. Snyder and Min (2012) found that tomato accessions resistant to aphids were also resistant to Liriomyza sp. The effect of major nutritional components in tomato leaves on the population densities of the considered pests Data in Tables (5 & 6) reveal that the effect of (N) was positive and highly significant on all considered pests on the cultivars Hybrid Super and Crystal HYB.…”

The present investigation was conducted to follow up the seasonal fluctuations in the population densities of B. tabaci, aphids, E. decipiens and T. absoluta on tomato plants and to investigate the susceptibility of two grown cultivars to the infestation with these pests.…”

Experiments were carried out at tomato field at Qalyubyia Governorate, Egypt cultivated with two different cultivars to test its susceptibility to infestation with Bemisia tabaci (Gennadius); aphids {Aphis gossypii and Myzus persicae (Sülzer)}; Empoasca decipiens Paoli and Tuta absoluta (Meyrick) in addition to the seasonal abundance of these pests on the two cultivars in two successive summer seasons (2012 and 2013). Results indicated that B. tabaci and aphids had two peaks of abundance in May and June in both years on both cultivars. E. decipiens also had two peaks of abundance in May and June in both years with no significant difference between the two cultivars. The two tested cultivars almost harbored the same population density of the immature stages of T. absoluta during summer season, 2012. The pest had only one peak during the last week of May. There was negative and highly significant correlations between the population densities of all considered pests and the numbers of hairs (trichomes) present on tomato leaves sampled on 20 May and 4 June except for aphids which disappeared during hot summer months on the cultivar Hybrid Super. In the third sampling date (20 June, 2013), the correlation was also negative and highly significant with the population of B. tabaci and positive with the population of T. absoluta. The same trend was observed on the cultivar Crystal HYB. The effects of (N), (P) and (Ca) were positive and highly significant on all considered pests on both cultivars. The effect of (K) was negative and highly significant on all considered pests on both cultivars. The effect of (Mg) was positive and highly significant on the cultivar Hybrid; while it was negatively correlated with sap sucking pests only on the cultivar Crystal. Data indicate that the effect of Fe, Zn and Mn was positive and highly significant on both cultivars and Cu was negatively affected these pests on both cultivars.

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 Sülzer), potato leafhopper, Empoasca decipiens Paoli and tomato leafminer, Tuta 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. The effect of nitrogen and calcium on all investigated pests was positive and highly significant; while the effect of potassium was negative and highly significant. The effect of phosphorus was positive and highly significant on all sap sucking pests on the cultivar Crystal HYB; while magnesium had positive and highly significant effect on the investigated pests on the cultivar Hybrid Super. The effect of iron, zinc and manganese was positive and highly significant and cupper was negatively affected these pests on both cultivars.
