TRAP DESIGN EFFECT ON CAPTURE OF CARPOPHILUS SPP (COLEOPTERA, NITIDULIDAE) USING SYNTHETIC AGGREGATION PHEROMONES AND A COATTRACTANT

In a series of experiments conducted in stone fruit orchards in southe rn Australia, water-based funnel-type traps baited with synthetic aggr egation pheromone and fermenting bread dough, trapped 3- to 7-fold as many Carpophilus beetles (primarily C. davidsoni) than wind-oriented p ipe traps or dry funnel traps. The efficacy of dry funnel traps but no t pipe traps, appeared to be improved by using water-filled collecting bottles. The potential for using water-based funnel traps in populati on suppression of Carpophilus spp. in stone fruit orchards through mas s trapping is discussed.
