Abstract
Two field experiments were conducted during 2020 at the Plant Protection Research Station at Qaha,
Qalubiya Governorate. Those included fluctuation in population growth rate of Bemisia tabaci, Aphis gossypii,
Thrips tabaci and Tetranychus urticae in addition to evaluation of the susceptibility degree of 4vegetable
marrow varieties (hybrid Aziad, hybrid Marseille, Askandrany and Amna)to infestation by previously
mentioned pests. The study also included the application of lemon oil, ginger oil, fenugreek oil, green tea oil
and egyxide plus(water soluble natural oil)for control of these each of pests. The 5oils (at 500 and 1000ml.)were
mixed with 250gm hivit 80%WDG. Also, 5insecticides; Vapcomic 1.8%EC, Mobet, Trivap 75%WP, Oecos
3.2%EC and Hivit 80%were assayed at the recommended concentrations.Aziad variety could be fairly
categorized as the highest susceptible(S)to infestation with the above mentioned pests of vegetable marrow
plants, with means 31.61, 19.45, 1.76 and 2.31/leaf to B. tabaci, A. gossypii, T. tabaci and T. urticae,
respectively/leaf.Obtained data indicated that A. gossypii recorded the highest growth rate 6.77, taking time
difference 7days at Marseille variety. As for the anatomical measurements, those were the highest in case of
Amna variety and the lowest in Aziad variety. Also, highest fruit yield was that of Amna variety and lowest in
Aziad variety.The obtained records exhibited, that vapcomic and fenugreek oil+Hivit(1000ml+250gm)caused
the significantly highest reduction against B. tabaci and A. gossypii counts on Aziad variety, as the recorded
average of their reductions after 14days of first and second spray were(88.8 and 88.1%),(93.2 and
91.3%)and(96.2 and 95.2%), respectively.
