This study was carried out to investigate efficiency of Phytomyza orobanchia Kaltenbach, 1864 (Diptera: Agromyzidae) on Orobanche aegyptiaca and O. ramosa parasitizing tomato crops under natural conditions, in Southeast Anatolia Region (Diyarbakır and Mardin provinces) in 2008. Trials were practiced using a randomized parcel design with five release ratios (0, 4, 6 and 8 pupae/cage and open field control) and with six replicate each. Highly significant differences were detected among treatments in both locations. The differences among treatments were ordered from the most effective ones to the least as; 8, 6 pupae/cage, open field control, 4 pupae/cage, and control lattices that without releasing pupae. The efficiency of P. orobanchia increased significantly by increasing the number of released P. orobanchia pupae, while there was no effect in control cages. Compared to pupae released cages open fields showed almost the same activity levels of P. orobanchia as that four pupae or sometime slightly higher than four pupae. Obtained data may provide valuable information for improving effective biological control program in the frame of integrated pest management of Orobanche aegyptiaca and O. ramosa.
