Studies on the Resistance of Chestnut Trees (Castanea spp.) to Chestnut Gall Wasps (Dryocosmus kuriphilus YASUMATSU)

open access: yesJournal of the Japanese Society for Horticultural Science, 1975
Various kinds of necroses found in bud tissues of hosts (chestnut trees) were caused by oviposition and consequent gall formation by chestnut gall wasps. Necroses resulted from resisting reaction against parasites were initiated in parenchymatous tissues around vascular bundles which intervened between gall and normal tissues, and were classified as ...
