Some aspects of the integrated control of cucurbits fruit fly Dacus ciliatus (Loew) (Diptera: Tephritidae) on cucumber crop

Abstract

Field experiment  was carried out during the autumn season in the Alam area in the east of Tikrit to study the integration of the three types of chemical pesticides (Media, Wide and Decis) and four cucumber varieties (Gazer, Amin, Najim and  Zena) and Mass trapping technique by using Macphil traps that they contained female food attractive FLYCAP MASS to control  cucurbits fruit fly Dacus ciliatus (Loew) in three open fields, the first field applied pesticides only, the second field applied pesticides and Mass trapping technique traps, and the third field for comparison (without pesticides and traps), was conducted two sprays for pesticides, the first spray after fruits setting directly and the second spray after week of the first spray .                     

Results showed that the application of pesticides alone in the first field had not been able to give good protection to the cucumber fruits from injury with cucurbits fruit fly Dacus ciliatus while  the treatment of pesticides , varieties and Macphil traps in the second field that integrated each other in reducing the percentage of infected fruits  to achieve good protection of the fruits and they showed  that Integration between  Mass traping technique  by using Macphil traps  that they contained FLYCAP MASS and Najim variety and Decis pesticide gave lower infected fruits percentage from 84.15% to 18.61%  after one week of second spray, and reduce the number of larvae in Najim variety  fruits from 7 Larva / fruit to 0.67 Larva / fruit and they  reduced  numbers of adults in the second field to 69.15% compared with the reduction percentage of the adults did not exceed 27.15% in the first field (treated with pesticides only) after one week of second spray.
