Revision of Canadian Eurytomidae (Hymenoptera, Chalcidoidea) associated with galls induced by cynipid wasps of the genus Diplolepis Geoffroy (Hymenoptera, Cynipidae) and description of a new species
Pensoft Publishers, 2017Co-Authors: Miles Y. Zhang, Michael W Gates, Joseph D. ShorthouseAbstract:Eurytomids are small parasitic wasps associated with many communities of phytophagous insects. In most cases, the accurate identification of eurytomids is impeded by inadequate species descriptions that do not include figures of diagnostic features, and keys that are difficult to use. Here, diagnostic features and redescriptions are provided for both sexes of the eurytomids associated with galls induced by cynipid wasps of the genus Diplolepis Geoffroy found on shrub roses across Canada. Consequently, six species of Eurytoma Illiger, along with Tenuipetiolus ruber Bugbee, are dealt with. One new species, Eurytoma shorthousei Zhang & Gates, sp. n., is described. Two species are synonymized, E. hebes Bugbee, 1973 and E. spina Bugbee, 1951 under E. longavena Bugbee, 1951, syn. n. Several new host and distribution records are reported. A dichotomous key is provided for both sexes of all seven species using photographs and scanning electron microscopy images

biology of Eurytoma sivinskii an unusual eurytomid hymenoptera parasitoid of fruit fly diptera tephritidae pupae
Florida Entomologist, 2008Co-Authors: J Menacorrea, Michael W Gates, John Sivinski, Ricardo Ramirezromero, Martin AlujaAbstract:Abstract The recently described Mexican parasitic wasp Eurytoma sivinskii Gates and Grissell (Hymenoptera: Eurytomidae), attacks Anastrepha obliqua (Diptera: Tephritidae) pupae in the soil. The life cycle (egg to adult) is completed in 23.1 (± 2.1) d (mean ± S.E.) at 27 ± 2°C. Females were capable of superparasitism and laid 1-8 eggs per host (2.59 ± 1.56, mean ± S.E.), but invariably only 1 adult parasitoid emerged. Oviposition occurred primarily in the medial and posterior portions of the host. Eurytoma sivinskii is ectoparasitic since 100% of the eggs are laid within the internal cavity of the puparium and on the surface of the pupa of the host fly. In no case were first and second instars parasitized. However, 1 third-instar out of 625 fly pupae exposed, yielded a single parasitoid per host. Eight-day-old pupae yielded the most parasitoids although females laid eggs in 1-d- to 14-d-old pupae. There were no significant differences in rates of parasitism among female E. sivinskii of different ages. Adul...

Entomological News, 2008Co-Authors: Michael W Gates, John Sivinski, Mena J Correa, Martin AlujaAbstract:3 ABSTRACT: We describe and illustrate for the first time the egg, larva, and pupa of Eurytoma sivin- skii Gates and Grissell (Hymenoptera: Eurytomidae), a parasitoid that attacks Anastrepha obliqua (Macquart) pupae in Veracruz, Mexico. We obtained the immature stages of E. sivinskii using lab-reared A. ludens (Loew) pupae as hosts.

Zootaxa, 2008Co-Authors: Michael W Gates, Gérard DelvareAbstract:Eurytoma erythrinae Gates and Delvare, new species, is described and illustrated. This species was reared from fieldcollected galls on Erythrina spp. (Fabaceae) induced by Quadrastichus spp. (Hymenoptera: Eulophidae), in Tanzania, Ghana, and South Africa. It is compared with very similar African species, Eurytoma radicicola Risbec. Afrotropical species classified in Eurytoma are reviewed and twenty-seven new combinations are proposed: Aximopsis acaciacola (Hedqvist) comb. n., A. caryedocida (Rasplus) comb. n., A. lamtoensis (Rasplus) comb. n., A. mateui (Hedqvist) comb. n., A. mimosarum (Rasplus) comb. n., A. obocki (Risbec) comb. n., A. oryzivora (Delvare) comb. n., A. saharensis (Hedqvist) comb. n., A. senegalensis (Risbec) comb. n., A. tropicana (Risbec) comb. n., Bruchophagus conapionis (Rasplus) comb. n., Fronsoma ellenbergeri (Risbec) comb. n., Gibsonoma amborasahae (Risbec) comb. n., G. aphloiae (Risbec) comb. n., G. bararakae (Risbec) comb. n., G. eugeniae (Risbec) comb. n., G. mandrakae (Risbec) comb. n., G. pauliani (Risbec) comb. n., G. plectroniae (Risbec) comb. n., G. tavolae (Risbec) comb. n., Philolema arachnovora (Hesse) comb. n., P. arnoldi (Waterston) comb. n., P. bambeyi (Risbec) comb. n., P. braconidis (Ferriere) comb. n., and P. syleptae (Ferri_re) comb. n., Phylloxeroxenus cressoni (Howard) comb. n., and Sycophila plectroniae (Risbec) comb. n. Lectotypes are designated for ten species: Eurytoma perineti Risbec, E. radicicola Risbec, E. toddaliae Risbec, Gibsonoma amborasahae (Risbec), G. aphloiae (Risbec), G. eugeniae (Risbec), G. mandrakae (Risbec), G. pauliani (Risbec), G. tavolae (Risbec), and P. bambeyi (Risbec). We also provide a checklist of Afrotropical species that are or were classified in Eurytoma and tabulate the known host/associations of these species with references.

a new phytophagous species of Eurytoma hymenoptera eurytomidae attacking werauhia gladioliflora bromeliales bromeliaceae
Zootaxa, 2004Co-Authors: Michael W Gates, Alfredo CascantemarinAbstract:Eurytoma werauhia Gates, new species, is described and illustrated. This species was reared from the floral buds of Werauhia gladioliflora (Wendl.) (Bromeliales: Bromeliaceae), in Costa Rica. This plant represents a new host record for the genus. Eurytoma werauhia is compared with other known species of Eurytoma, primarily due to its host and metasomal coloration.

a review of the palaearctic species of the genus Eurytoma ill of the robusta group with description of a new species from uzbekistan hymenoptera chalcidoidea eurytomidae
Entomological Review, 2020Co-Authors: M. D. Zerova, V N FursovAbstract:A morpho-biological review and analysis of the Palaearctic species of the robusta group of the genus Eurytoma is presented. The differences between the species of the robusta group and the other species-groups of the genus Eurytoma are described. The hosts of the species of the robusta group and their geographical distribution are listed. A key to 62 Palaearctic species of the robusta group is compiled. A new species, Eurytoma uzbekistanica sp. n. belonging to the robusta species-group and morphologically closest to Eu. nochurae Zerova is described from Uzbekistan. Photographs of the types of Eu. uzbekistanica sp. n., Eu. herbaria Zerova, Eu. ibaraca Zerova, Eu. paramygdali Zerova et Fursov, Eu. armenica Zerova et Fursov, and Eu. nagoya Zerova, and also of the non-type specimens of Eu. dentata Mayr, Eu. robusta Mayr, and Eu. pyrrhidii Erdos are given. The holotype of the new species and material of the other species discussed are deposited in the collection of I.I. Schmalhausen Institute of Zoology of the National Academy of Sciences of Ukraine (Kyiv).

emended description and new data on the distribution of Eurytoma campanulae zer hymenoptera chalcidoidea eurytomidae
Entomological Review, 2020Co-Authors: M. D. Zerova, S I KlimenkoAbstract:New data on the distribution of Eurytoma campanulae Zer., based on material from various parts of Ukraine and that from Finland received from Dr. Veli Vikberg, are reported. The characteristic morphological features of Eu. campanulae and the other members of the campanulae species-group are discussed. Specific traits of this species-group are outlined; this group is notable within Eurytoma due to the characteristic sculpture of the thorax and the features of the metasomal tergites. A key to the species of the campanulae species-group is given. The entire material mentioned in the paper is deposited in the collection of I.I. Schmalhausen Institute of Zoology, National Academy of Sciences of Ukraine (Kyiv).

new data on trophic associations and distribution of the eurytomid genera Eurytoma illiger and systole walker hymenoptera chalcidoidea eurytomidae
Entomological Review, 2013Co-Authors: M. D. Zerova, Ya L SeryoginaAbstract:New data on the distribution and trophic associations are given for three eurytomid species: Eurytoma infracta Mayr, Eu. salvicola Zerova, and Systole (Trichosystole) cuspidata Zerova. Eurytoma infracta and S. (T.) cuspidata were reared in Portugal, the first species from Cynipid galls on Salvia sclareoides Brot. (Lamiaceae), the second, from seeds of the same plant. Eurytoma salvicola Zerova was found for the first time in France, having being reared there from galls of Oxyacina tibialis R.-D. (Diptera, Tephritidae) on Rosmarinus officinalis L.
