Dispersal and effects of barriers on the movement of the New Zealand hover fly Melanostoma fasciatum (Dipt., Syrphidae) on cultivated land

Abstract: Dispersal within agricultural fields and the effects of different barriers on between-field movement of the New Zealand hover fly Melanostoma fasciatum were studied using ingested pollen as markers. Hover flies did not generally disperse more than 20 m from the pollen source. Gravid females had no significant wind-directed movement pattern whereas males significantly flew downwind. Flies tended to avoid flying over barren land: a dirt track, an asphalt road or a ploughed field all seemed to hamper hover fly dispersal equally. The implications for spatial arrangement of the flowering strips to enhance the biocontrol potential of hover flies are discussed.
