The use of some agricultural practices such as tillage and irrigation affected the natural population of Phytomyza orobanchia Kalt., the main active bioagent against broomrape in Egypt. During March of 2010/2011 season, fleshy plants of Orobanche crenata shoots were collected from faba bean fields. Under semi-field conditions, whole plants of Orobanche crenata shoots were buried at different depths (5, 10, 15, 20 and 25 cm) in sandy, sandy-loam and clay soil in pots and treated with three treatments of water (moistened, flooded and dry). At the beginning of the new activity season 2011/2012, emergence percentages of the broomrape fly, P. orobanchia from Orobanche shoots contained diapaused pupae were estimated, which were buried under the effects of different agricultural practices. Results revealed that the emergence percentage of Phytomyza adults had significantly reduced with increasing the depth of buried O. crenata shoots. Highest mean emergence percentage was (52.31%) occurred from puparia in Orobanche shoots buried in moist soil. On the other hand, sandy-loam soil was enough for emergence of 42.40%. It could be recommended to bury Orobanche shoots containing diapaused Phytomyza pupae at 5 cm depth after collected during March. After that it is recommended to cover the shoots with moistened and sandy-loam soil in order to increase the rate of initial Phytomyza population working in faba bean field against Orobanche crenata at the start of new season’s activity.
