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...

The 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...

Chromosomes 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...

گزارش سه گونه جدید زنبور گالزا (Hym.: Cynipidae) از ایران

طی نمونه‌برداری‌هایی که در سالهای 1383-1382 به منظور شناسایی حشرات گالزای بلوط در استان آذربایجان‌غربی انجام پذیرفت، سه نوع گال مختلف برای اولین بار از روی درختان بلوط Quercus infectoria جمع‌آوری گردید. زنبورهای مولد گال‌های جمع‌آوری شده، براساس مشخصات ظاهری گال‌ها شناسایی گردید. گونه‌های زنبور مولد این گال‌ها عبارتند از: 1- Andricus curvator Hartig, 1840 (شکل جنسی) تاریخ و محل جمع‌آوری: 10/3...
