Abstract
A field trial comparing the effectiveness of toxic targets impregnated with different formulations of the Musca domestica L. female sex pher omone (Z)-9-tricosene was conducted in a caged-layer, deep-pit poultry unit in southern England. Targets baited with 5 g of technical grade (Z)-9-tricosene, or 5 g of a 40% polymer bead formulation, caught sign ificantly greater numbers of M. domestica than control targets. This i ncrease in attractiveness of the pheromone-impregnated targets persist ed for at least 24 wk. However, mean daily catch rates of M, domestica at targets baited with 5 g of a 2% wettable powder formulation did no t significantly differ from control levels. Technical grade and bead f ormulations of the pheromone attracted significantly more males than f emales. However, the catches of female M. domestica at these pheromone -impregnated targets were significantly greater than female catches at control targets. Monitoring with sticky cards indicated that the intr oduction of toxic targets successfully suppressed adult M. domestica p opulation density for up to 13 wk. Possible hypotheses explaining the effect of (Z)-9-tricosene on female attraction are discussed.
