Efficacy of thermal fog and partial spraying techniques for controlling bactrocera zonata and ceratitis capitata (Diptera : Tephritidae )‎ on mango in Qalyubiya governorate

الملخص EN

This investigation may be considered one of the rare attempts to make evaluation between thermal fog and partial spray techniques to control both of Bactrocera zonata ( Saunders ) and Ceratitis capitata (Wiedemann) (Diptera: Tephritidae ) on tall mango orchards in Egypt .

Thermal fog as a new technique gave promising results represented in good distribution and penetration of fog clouds at various parts of tree during the evening or at sun rise under climatic inversion condition, saving time , water consumptions and labors required for chemical application when compared with partial spray technique .

Also a drastic difference in the rate of performance ( fed.

/ day ) between IGEBA TF 35 handle fogger machine and Hand Heldsprayer CP-3 ( 17.12 and 1.5 fed./ day), respectively .

Data showed that C.

capitata was more sensitive than B.

zonata represented in percentages reduction by using thermal fog and partial spray techniques .

A highly significant difference was recorded between recommended dose of thermal fog and partial spray techniques for controlling both B.

zonata and C.

capitata represented in mean number of captured flies in Mcphail traps .

No significant difference between half recommended dose with thermal fog technique and partial spray technique for controlling fruit flies was also noticed .

Moreover significant difference in mean numbers of captured flies inside Mcphail traps were recorded four weeks than between two weeks after application of B.

zonata.
