Eco-friendly control strategy based on sex pheromone andor aggregation traps; sequence of partial chemical sprays on two grape varieties against Ceratitis Capitata Wied. (Diptera: Trypetidae)‎

Abstract EN

Field experiments were conducted in a private vineyard located at kilo 54^th Cairo-Alexandria Desert Road in the New Sphinx City, Cairo, Egypt, throughout two successive seasons (2020 and 2021).

The present investigation was adopted for attaining eco-friendly, and safer protection strategy for controlling fruit of fly Ceratitis capitata on grape by mass attracting traps.

Also, the study aimed to determine the susceptibility of two seedless grape varieties, representing white- and red grape, to fruit fly infestation.

Three types of mass attracting traps namely: Jakson, McPhail and Fly CAP were experimented for catching medfly adults.

Moreover, sequence of partiall sprays of Buminal with one of two insecticides (Malathion 57% and/or Tracer 24% ) that concurrently used with used traps were also evaluated.

Generally, caught fruit flies started from the third decade interval (21^st: 30^th of April) and continued up to the end of May.

Meanwhile, the highest mean of G-FTD was observed through the first decade of May, especially in the white grape variety (21.33 and 9.78 in seasons 2020 and 2021, respectively).

The results indicate that, thin thickness of fruit skin and/or the white yellowish color of grape berries could enhance a high attraction of the Medfly, more than that of red grape berries.

Jackson paper yellow trap showed an early high ability in capturing the fruit fly at the beginning of the 2^nd decade of April.

Meanwhile, McPhail trap was the superior tested throughout the preharvest interval.

Also, the results strongly indicate that both insecticides (malathion and Spinosad) that mixed with Buminal used in the partial sprays could increase the insect's orientation to food baits in Fly CAP and McPhail traps.

It is clear that applying partial spray treatment concurrently with attracting traps highly decreased the mean number of captured medflies indicating a good Eco-friendlystrategy to control this insect pest.
