Differential Gene Expression in Chestnut Buds Following Infestation by Gall-Wasp (Dryocosmus kuriphilus Yasumatsu, Hymenoptera: Cynipidae)
The chestnut gall-wasp Dryocosmus kuriphilus Yasumatsu, an insect native of China, was found in 2002 for the first time in Europe, and specifically in North western Italy (Cuneo province). The cynipid lays eggs into dormant buds and, in the following year, causes the development of galls on leaves, sprouts and inflorescences, due to the feeding activity of larvae. The wasp has an effect both on...
متن کاملGall structure affects ecological associations of Dryocosmus kuriphilus (Hymenoptera: Cynipidae).
Gall wasps (Hymenoptera: Cynipidae) induce structures (galls) on their host plants that house developing wasps and provide them with protection from natural enemies. The Asian chestnut gall wasp, Dryocosmus kuriphilus Yasumatsu, is an invasive pest that is destructive to chestnut (Castanea spp.). An improved understanding of the interactions among D. kuriphilus, its host, and its natural enemie...
متن کاملNew Gall Wasp Species Attacking Chestnut Trees: Dryocosmus zhuili n. sp. (Hymenoptera: Cynipidae) on Castanea henryi from Southeastern China
A new gall wasp species, Dryocosmus zhuili Liu et Zhu, is herein described from the southeastern Fujian province of China. The new species induces galls on trees of Henry's chestnut, Castanea henryi, which is also a native host for the notorious Oriental chestnut gall wasp (OCGW, Dryocosmus kuriphilus Yasumatsu). D. zhuili overlaps with OCGW in emergence time and induces galls morphologically s...
متن کاملBiological Control of the Invasive Dryocosmus kuriphilus ( Hymenoptera : Cynipidae ) - an Overview and the First Trials
Background and Purpose: Dryocosmus kuriphilus is a globally invasive insect pest, spreading very quickly in new habitats and making serious damage to sweet chestnut forests in Croatia and in several other European countries. Indigenous parasitoid species trophically associated with oak gallwasps have adapted to this new host but cannot effectively regulate its population density. Classical biol...
متن کاملChestnut Species and Jasmonic Acid Treatment Influence Development and Community Interactions of Galls Produced by the Asian Chestnut Gall Wasp, Dryocosmus kuriphilus
Jasmonic acid (JA) is a plant-signaling hormone involved in defenses against insects and pathogens as well as the regulation of nutrient partitioning. Gall wasps (Hymenoptera: Cynipidae) induce the formation of galls on their host plants, which house immature wasps and provide them with nutrition and protection. The goal of this study was to investigate the effects of JA application on gall dev...
