Nahrungsfindung und Chemotaxien bei holzbewohnenden Käfern

Summary There is very little data on taste orientation in wood feeding insects. A comparison of the even fewer known examples of scent orientation and the role of scent materials in food finding by wood dwelling beetles shows a wide range of chemical possibilities. These vary between an adaptation to a few, strictly definable, mutually very similar compounds and a reaction to different and varied mixtures of substances. It must be ascertained whether, in the latter case, certain common groups of substances are decisive or whether the reaction capabilities of certain fresh wood insects is actually very wide chemically.
