Gall 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 کاملThe population biology of oak gall wasps (Hymenoptera: Cynipidae).
Oak gall wasps (Hymenoptera: Cynipidae, Cynipini) are characterized by possession of complex cyclically parthenogenetic life cycles and the ability to induce a wide diversity of highly complex species- and generation-specific galls on oaks and other Fagaceae. The galls support species-rich, closed communities of inquilines and parasitoids that have become a model system in community ecology. We...
متن کاملChromosomes of Belonocnema treatae Mayr, 1881 (Hymenoptera, Cynipidae)
Chromosomes of the asexual and sexual generation of the gall wasp Belonocnematreatae Mayr, 1881 (Cynipidae) were analyzed. Females of both generations have 2n = 20, whereas males of the sexual generation have n = 10. Cyclical deuterotoky is therefore confirmed in this species. All chromosomes are acrocentric and form a continuous gradation in size. This karyotype structure is probably ancestral...
متن کاملNew species of cynipid inquilines of the genus Synergus (Hymenoptera: Cynipidae: Synergini) from the Eastern Palaearctic.
Eight new species of cynipid inquilines, Synergus abei Melika & Schwéger, S. belizinellus Schwéger & Melika, S. changtitangi Melika & Schwéger, S. formosanus Schwéger & Melika, S. ishikarii Melika & Schwéger, S. kawakamii Tang & Melika, S. khazani Melika & Schwéger and S. symbioticus Schwéger & Melika, from the Eastern Palaearctic are described. Descriptions, diagnoses, biology, and host associ...
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...
