Responses of female New World screwworm flies, Cochliomyia hominivorax, to swormlure-4 in the laboratory.
The behaviour of 4-day-old virgin female New World screwworm flies Cochliomyia hominivorax Coquerel was investigated in a wind tunnel using video. Addition of the screwworm attractant swormlure-4 to the airstream resulted in an increase in the number of take-offs and in the duration of flight. In the presence of swormlure-4 the flight speed decreased and the rate of turning increased. Take-off was significantly orientated upwind during the period when swormlure-4 was added to the airstream, and significantly orientated downwind in the period after the addition of swormlure-4. The possible means by which this species finds a point source of odour in the field are discussed and compared with the mechanisms used by other flies.
