Abstract :
This study was carried out to study the effect of the insect infestation by The Green Peach Aphid, Myzus persicae (Sulzer) (Hemiptera: Aphididae) and The Greenhouse Whitefly, Trialeurodes vaporariorum (Westwood) (Homoptera: Aleyrodidae) on the quantity of the annual production of the strawberry crop, Fragaria ananassa (L.). This study was carried out at Tokh region (Qaliobya Governorate) during two successive seasons 2020, 2021 under glasshouse conditions.
This study was divided into three parts, first part studied the population fluctuation of M. persicae and T. vaporariorum on strawberry plants during the two successive seasons, second part studied the effect of insect infestation by the two insects on the quantity of the annual production of strawberry fruits at the two successive seasons compared to control (which did not infest with any insect) and third part studied the effect of insect infestation by the two insects on the internal components of strawberry fruits.
Results obtained showed that the infestation by M. persicae and T. vaporariorum reduced the quantity of annual production of strawberry fruits compared to control (which was non-infested by the same insects). Also, results obtained showed that the infestation by the same insects reduced both total sugar and total protein on strawberry fruits compared to control.
