The basic biology of the female woodwasp and factors affecting oviposition behaviour are described. The rate of egg deposition 1s related to the physiological condition of the host tree; it is demonstrated that the wasp's ability to assess its host tree is directly related to the osmotic quality of the phloem sap.
