Abstract
BackgroundThe Ministry of Environment, Water and Agriculture in Saudi Arabia has begun funding some projects to set up some agricultural pest control programs. Therefore, it is very important to enumerate all the predacious or parasitic insects that live on or in other agricultural insect pests and have the potential to become biological control agents against these pests.ResultsIn the present study, nine fly species of potential importance in biological pest control are recorded for the first time from Saudi Arabia, namely, Spogostylum ventrale Bezzi, 1924, Prothaplocnemis anthracina (Becker, 1902) [family Bombyliidae], Alloxytropus anomalus Bezzi, 1925, Scenopinus minusculus (Séguy, 1934) [family Scenopinidae], Actorthia frontata Kröber, 1912, Hoplosathe brevistyla Lyneborg & Zaitzev, 1980 [family Therevidae], Hilara sp. [family Empididae], Tomosvaryella demeyeri Kuznetzov, 1993 [family Pipunculidae] and Orchisia costata (Meigen, 1826) [family Muscidae]. In addition, this is the first time to record the four genera Prothaplocnemis Bezzi, Alloxytropus Bezzi, Hilara Meigen and Orchisia Rondani from Saudi Arabia. World and local distributions, diagnoses, feeding behaviors and some colored photographs of recorded species are provided.ConclusionIn the present study, nine species of predacious and parasitic flies belonging to nine genera and six families are recorded for the first time in Saudi Arabia.
