Ent. Scand. Suppl.
Some important principles of exocrine signal systems are defined. Particular emphasis is placed on seven pairwise properties which can be useful in discussing systematic and phylogenetic aspects of these systems. A few systematic and phylogenetic problems, such as determination of species, grouping into genera and aspects of exocrine signal systems in the evolution of organisms and coevolution processes, are also defined and the possible contribution to their solution from knowledge about exocrine signal systems is discussed. The properties of the exocrine signal system and the systematic and phylogenetic problems are then examined, utilizing examples from aculeate Hymenoptera.
