| English abstract | The occurrence of aphidophagous syrphids was studied on citrus, cabbage, cucumber, wheat and potato crops. Samplings were done every 15 days from August to December 2002. The species recorded were: Ocyptamus gastrostactus (Wiedemann, 1830), Allograpta exotica (Wiedemann, 1830), Pseudodorus clavatus (Fabricius, 1794) and Ocyptamus anthiphates (Walker, 1849). P. clavatus occurred on all the crops and showed the highest population density (72%). It was followed by O. gastrostactus (16%), A. exotica (11%) and O. anthiphates (1%). The occurrence of the syrphids was correlated with the weather conditions and the presence of aphids |
