Nestmate Recognition in Social Insects: What Does It Mean to Be Chemically Insignificant?
2020
Frontiers in Ecology and Evolution
Social insects use the blend of hydrocarbons present on their cuticle to efficiently distinguish nestmates from aliens. Intruders must therefore find a strategy to break the recognition code in order to exploit the colony resources. Twenty years ago, the concept of "chemical insignificance" was introduced to characterize those parasites bearing almost no recognition cues on their cuticle, thus appearing chemically undetectable to their hosts. In some cases, intruders do possess cuticular
