Jw. Chapman et al., EVALUATION OF 3 (Z)-G TRICOSENE FORMULATIONS FOR CONTROL OF MUSCA-DOMESTICA (DIPTERA, MUSCIDAE) IN CAGED-LAYER POULTRY UNITS, Journal of economic entomology, 91(4), 1998, pp. 915-922
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.
