New Synthesis: The Chemistry of Partner Choice in Insect-Microbe Mutualisms.

The authors focus on mutualism between insects and microorganisms. Topics discussed include role of insects in ecology and evolution of host organisms, the mechanism of partner selection through signaling, and short-distance recognition of mutualistic partners by odors or chemicals to establish symbiosis. They also mention ambrosia beetles which transmit their symbiotic fungus vertically in specialized pouches.
