This study was carried out to evaluate the efficiency of three insecticides (aphicides): (Vertimec, Malathion and Chloropyrifos), three plant extracts: (Neemazal, Azadirachta and Glycine) and three plant oils:  (Citronella oil, Jojoba oil and Helianthus oil) on controllingGreen Peach Aphid, Myzus persicae (Sulzer) (Hemiptera: Aphididae) which infesting squash plants ( Cucurbita pepo L.) under greenhouse conditions. And this study was carried out at two locations (governorates), Perkash region (Giza Governorate) and Tokh region (Qaliobya governorate) during season 2021.
               At Giza Governorate, data obtained showed that the compounds effectively were arranged to descend as follows; insecticides, plant extracts and plant oils. Also, insecticides effectively were arranged to descend as follows (Vertimec, Malathion and Chloropyrifos), respectively, whereas the general effect % was 96.9, 96.5 and 96.1% respectively. The plant extracts effectively were arranged as follow: Neemazal, Azadirachta and Glycine, whereas the general effect % were 94.8, 94.3 and 94.1% respectively. Lastly, plant oils effectively were arranged as follows: Citronella oil, Jojoba oil and Helianthus oil respectively, whereas the general effect % was 91.8, 91.5 and 91.2% respectively.
             Vertimec proved itself to be the most insecticide effective, Neemazal proved itself to be the most plant extracts effective and Citronella oil proved itself to be the most plant oils effective. All extracts recorded significant differences between them and control.
            As the same trend data obtained at Qaliobya Governorate at the same season 2021.
