Abstract EN
Tomato, Lycopersicon esculentum (Solanacea) is one of the most important vegetable crop in Egypt.
Two Field experiments were conducted during two winter successive seasons of 2013/2014 and 2014 /2015 at Gizera Bele, Banha, Qalyubiya Governorate .
The study included population fluctuation, the population growth rate of the whitefly, Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae); the aphid, Aphis gossypii Glover (Hemiptera: Aphididae) ; the spider mite, Tetranychus urticae (Koch) (Acari: Tetranychidae) and evaluation the susceptibility degree of three varieties of tomato (omnia, arika and safira) for infestation by previously mentioned pests.
The study, also included the control of these pests by sesame oil; biofly (Beauveria bassiana) , abamactin and malathion.
The obtained results revealed that the highest mean population fluctuation (for 15 weeks) of B.
tabaci (22.1, 61.2, 88.6) and (10, 17.7, 28.9) nymph and adult stages/ 5 leaves, followed by mean population of T.urticae (14.9, 5.3, 26.3) and (10.7, 9.0, 14.9) individuals/ 5 leaves of the three tomato varieties omnia, arika and safira during the two seasons, respectively, while population of A.
gossypii was lowest mean population.
Also the results revealed clearly susceptibility degree of safira variety was susceptible to infest with the above mentioned pests of tomato plants during the two seasons, with mean 58.73 , 10.6 and 20.6 (individual) / 5 leaves , respectively .
Present data indicated that B.
tabaci recorded the highest growth rate (23.64 and 4.57), taking time difference 14 days at safira variety in the first and second season, respectively.
Our data exhibited, sesame oil and abamactin gave the significant highest reduction against B.
tabaci, A.
gossypii and T.
urticae on tomato plants, as the average of their reductions after 14 days of spraying were (80.9% , 78.1% , 69.8%) and (77.6, 86.3, 71.4%), respectively .
