Abstract
The population fluctuation of  Bemisia tabaci (Genn.) studied on winter plantation of cucumber plant  Cucumis sativus L.  of 2018/2019& 2019/2020 seasons under greenhouse condition at Giza governorate, Egypt and, the insecticidal activities of two heavy nano metals (cu++ & mg++) and two commercial oils (camphor& Piper nigrum), its concentrations compared with recommended bio-insecticide (biofly) and recommended chemical insecticide (actara)  were evaluated against B. tabaci (eggs & immature stages). The high infestation were in 2nd week of November and 2nd week of December with 428 eggs/10 leaves & 390 nymphs/10 leaves, respectively in season 2018 /2019, and recoded highly infestation in 2nd and 4th week of November with 390 eggs/10 leaves & 423 nymphs/10 leaves, respectively in the season 2019/2020.  Camphor oil was the most effective with mortality percent 97.6% followed by Piper nigrum oil (93.6%) compared with chemical insecticide (actara).
