A new record of fungus-beetle symbiosis in Scolytodes bark beetles (Scolytinae, Curculionidae, Coleoptera)

The most evolutionarily advanced form of symbiosis between wood-decaying fungi and wood-boring beetles (Coleoptera, Curculionidae: Scolytinae and Platypodinae) is the ambrosial habit, or fungus farming. Here we present a discovery of a new origin of the ambrosia symbiosis in Scolytodes unipunctatus. Feeding on symbiotic fungi and the spatial organization of the gallery system of S. unipunctatus is typical for ambrosia beetles, but not for...
