Visual responses of tsetse flies (Diptera: Glossinidae) to odour-baited targets

摘要: Field studies in Zimbabwe showed how targets 1 m tall and 25–400 cm wide, composed of vertical panels visual material net baited with odours acetone, 1-octen-3-ol, phenols, could be refined for controlling Glossina morsitans Westwood G. pallidipes Austen. Attraction from a distance was not affected by swivelling movement but improved several-fold as the width increased 25 to 200 cm. Blue or blue/black were about effective black m. slightly more pallidipes. Fine coarse unattractive at long range flies avoided when close. The percentage tsetse alighting on before flying round up several times widened, non-shiny replaced blue shiny black, departure much expect panel width, being near 0% 85% 2 Most alighted first centre targets, especially where contrasted nearby blue.
