SUMMARY The interaction of environmental and genetic variation in hazelnut ( Corylus avellana ) shoot development and the behaviour, survival, and colonisation of eriophyid bud mites ( Phytoptus avellanae and Cecidophyopsis vermiformis ) were studied. The distribution of galled buds on shoots indicated that mites colonised only those buds formed during the mite migration period. The point of entry is probably the growing shoot tip. Once within this structure, as the shoot develops the mites have access to a succession of newly‐formed, bud primordia that are unprotected by bud scales. The relative accessibility of the apical meristem and bud primordia may affect host susceptibility.
