| Abstract: | A study was carried out to determine the optimal height, position (angle) and direction of yellow sticky traps for maximum attraction ofLiriomyza trifolii flies above gerbera plants. Catches at 30 cm above the plant tops were greater than at 70 cm above the tops. Horizontal and 45° angle traps caught larger numbers on the upper side, whereas with vertical traps there was no effect of side. Catches on vertical traps were greater than those on horizontal and 45° angle traps. Free-hanging vertical traps caught more flies than fixed traps facing north and south.
