The importance of trap color when collecting pollinators using the pan-trap method (English)
Abstract [en]

During the last century, the industrialization of agriculture has led to changes in the landscape and many important habitats have disappeared. Habitat loss and fragmentation and an increased use of agrichemicals have led to biodiversity declines in the agricultural landscape. The negative impacts on pollinators, in particular, must be taken serious because they provide an important ecosystem service when they pollinate crops. Monitoring of pollinators is therefore important to examine the factors that affect pollination. The pan trap method is commonly used in the monitoring of pollinating insects, but few studies have evaluated the effect of trap color on the collection of different groups of pollinators. Pollinators were collected using the pan trap method with blue, yellow and white bowls to examine if there were difference in the attraction to traps of different colors among different groups of pollinators. Lepturine beetles (Lepturinae spp.), bee beetles (Trichius spp.) and the bumblebees (Bombus spp.) preferred the blue traps while rose chafers (Cetoniidae spp.) and hoverflies (Syrphidae spp.) preferred the yellow traps. Hence pan traps of different colors may be specific for different groups of pollinators.
