Abstract
Field experiments with mass attracting traps were carried out in a private vineyard located at kilo 54 of the Cairo-Alexandria Desert Road in the New Sphinx City, Cairo, Egypt, throughout two successive seasons (2020 and 2021). The current study was conducted to achieve ecofriendly, safe control of fruit flies, Ceratitis capitata, on grapes using mass attracting traps and to determine the susceptibility of two grape varieties to fruit fly infestation. Two types of grape varieties were used: Prem Seedless and ARRA13, representing the white grape and red grape, respectively. Besides, the mixed trees of both varieties.
Also, three types of mass attracting traps namely: Jackson (Methyl eugenol), McPhail (Diammonium phosphate) and Fly CAP 48.21% VP (Diaminopentane + Ammonium acetate + Trimethylamine hydrochloride) were experimented and evaluated for catching medfly adults. Two admixtures of partial sprays were applied sequentially eight times with an interval of seven days, beginning April 10 and continuing until May 29. The mixture consisted of one liter of Buminal and 350 ml of either Malathion or Tracer, completed with water in a Knapsack sprayer.
So, this experiment consisted of 18 treatments arranged in a spilt plot design, each replicate represented with one tree. Noteworthy, the tested traps were used in the 1st season, meanwhile, the efficacy of traps alone and/or concurrently with the used partial sprays were evaluated in the 2nd season.
