Local spread of an exotic invader: using remote sensing and spatial analysis to document proliferation of the invasive Asian chestnut gall wasp

iForest - Biogeosciences and Forestry, 2012
Remote sensing and spatial analysis represent useful tools for modeling species’ dispersal, characterizing the spread of invasions and the invasability of a region, and thus allowing more accurate predictions for developing mitigation strategies ...

Torymus sinensis Kamijo, a biocontrol agent against the invasive chestnut gall wasp Dryocosmus kuriphilus Yasumatsu in Spain: its natural dispersal from France and the first data on establishment after experimental releases

Forest Systems, 2019
Aim of study: The globally invasive gall wasp, Dryocosmus kuriphilus Yasumatsu, 1951 (Cynipidae: Cynipini), reached Spain seven years ago and is already regarded as an important pest of chestnuts (Castanea spp.) in this country as well as worldwide.

Preservation of sweet chestnut genetic resources (Castanea sativa Mill.) against attack by chestnut gall wasp (Dryocosmus kuriphilus Yasumatsu, 1951)

Acta Agriculturae Slovenica, 2018
European sweet chestnut (Castanea sativa Mill.) is one of the most important wood species due to its environmental and economic role in many agro-forestry systems. Chestnut gall wasp (Dryocosmus kuriphilus Yasumatsu, 1951) is currently the most dangerous

Fungal community of necrotic and healthy galls in chestnut trees colonized by Dryocosmus kuriphilus (Hymenoptera, Cynipidae)

iForest - Biogeosciences and Forestry, 2019
Dryocosmus kuriphilus is a non-native pest that has recently spread through Europe with a special incidence along the Mediterranean Basin. The presence of this exotic wasp (originally from Asia) threatens stands and orchards of sweet chestnut (Castanea ...

Isolation of Zeatin from Larvae of Dryocosmus kuriphilus Yasumatsu1

HortScience, 1974
Abstract Cytokinin active compounds were isolated from larvae of D. kuriphilus within galls of Japanese chestnut, Castanea crenata , Sied, et Zucc. One of the compounds coincided with zeatin by T L C, G L C and Sephadex LH

Population Dynamics of the Chestnut Gall-Wasp, Dryocosmus kuriphilus YASUMATSU (Hymenoptera; Cynipidae)

Japanese journal of applied entomology and zoology, 1964
千葉県習志野および神奈川県大山のクリタマバチ発生地において,1960年より1964年にいたる5年間の個体群密度の年次変動を調査した。その結果,1. クリタマバチ個体群は,成虫-若令幼虫の期間に最も大きな死亡率が見られ,この死亡率はクリタマバチの個体群密度の年次変動に最も大きな影響を与えている重要な要因であると考えられる。2. クリタマバチの加害によって寄主植物の若枝を出す数が減少すると,一芽当たりに産まれる卵数が増加するため若令幼虫期に高密度の悪影響が現われるらしい。また,これが頻繁に現われるようになると,個体群は減少しはじめる。3. 幼虫寄生蜂の作用は,個体群密度の年次変動にとって重要な働きをなしてはいないらしいことがわかった。
