Abstract

Carpenter ants (Genus Camponotus) are well known as wood destroying insects in north- and southeuropean forests. As was demonstrated in a north-bavarian forest (340 mtrs. about sealevel) carpenter ants can cause important damage in Central Europe too. Whereas single stems with carpenter ants are spread over whole the forest area we found a high percentage of infestated stems in sunny and warm margin zones. The ants prefer in this region Norway Spruce, but settle also in Pines and occasionally in oaks, beeches and birchs. The forest damage was caused by C. herculeanus L. which is living more arboricol than C. ligniperda Latr. Basing on the high tendency to regurgitations in the feeding behaviour of ants, the tracermethod (J131 in honey-water-solution) was used to determine exactly the nest area of Camponotus-colonies. These experiments demonstrated the nesting-area of a single colony covering several stems and beeing much more wider than can be supposed by external visible damage.
