Pteromalid wasps (Hymenoptera: Chalcidoidea) associated with bark beetles, with the description of a new species from Kashmir, India
Journal of Asia-Pacific Biodiversity, 2019Co-Authors: Abdul Lateef Khanday, Abdul Ahad Buhroo, Avunjikkattu Parambil Ranjith, P. M. Sureshan, Ekaterina TselikhAbstract:Abstract Five species of Pteromalid wasps (Cheiropachus quadrum [Fabricius, 1787], Macromesus harithus Narendran, 2001, Metacolus sinicus Yang, 1996, M. parasinicus sp. nov., and Roptrocerus mirus [Walker, 1834]) reared from branch cuttings of Pinus wallichiana A. B. Jackson (Pinaceae) infested with three species of bark beetles (Ips stebbingi Strohmeyer, 1908, Polygraphus major Stebbing, 1902, and Pityogenes scitus Blandford, 1893) are reported from Kashmir, India. A new species of Metacolus from Kashmir is described and illustrated. A key for the identification of the six known species of Metacolus Forster, 1856 is given. Roptrocerus mirus and M. sinicus are reported for the first time from the Indian subcontinent. New host–parasite associations are reported for three species of Pteromalid wasps.

Record of six Pteromalid parasitoids from the soybean stem fly Melanagromyza sojae Zehntner with the description of a new species of Sphegigaster Spinola (Hymenoptera: Chalcidoidea) from Maharashtra, India
Oriental Insects, 2018Co-Authors: P. M. Sureshan, Babasaheb B. Fand, Kizhakayil NikhilAbstract:AbstractField surveys were carried out in Pune area of Maharashtra state in India during June–September of 2014 and 2015 to determine the parasitoid species associated with stem fly Melanagromyza sojae Zehntner infesting soybean. Ten species of parasitoid wasps emerged from the collected materials and included six species of Pteromlaidae, and one species each from the families Eurytomidae, Figitidae (= Eucoilidae), Braconidae and Eulophidae. Six Pteromalid parasitoids recorded were: Chlorocytus amaravathicus, Colotrechnus melghaticus, Halticoptera propinqua, Syntomopus carinatus, Syntomopus nigrus and Sphegigaster punensis sp. nov. Sureshan, Fand & Nikhil. Among Pteromalids, S. punensis was dominant parasitoid during the mid-season, whereas C. amaravathicus, C. melghaticus, H. propinqua, S. carinatus and S. nigrus were present in low number towards the end of the season. Whilst S. carinatus constitute an already reported parasitoid species from M. sojae, this study reports for the first time M. sojae as a...

Diversity of Pteromalids (Pteromalidae: Hymenoptera) among three Rice growing zones of Tamil Nadu, India
Annals of Plant Protection Sciences, 2017Co-Authors: J. Alfred Daniel, K. Ramaraju, V.k. Raseena Farsana, P. M. SureshanAbstract:Surveys were conducted to explore the Pteromalid fauna in rice ecosystems of Tamil Nadu in three different rice growing zones viz., Western zone, Cauvery delta zone and high rainfall zone. The study recorded a total of 82 individuals that represents 2 subfamilies, 6 genera and 13 species. Alpha and beta diversity were computed for three zones and the diversity indices (Simpson's index, Shannon-Wiener index, Pielou's index) revealed high rainfall zone as the most diverse zone, while Cauvery delta zone being the least diverse. However, 32 out of 82 individuals were collected from Western zone and thus ranks first in species abundance. Trichomalopsis thekkadiensis was the dominant Pteromalid species in the rice ecosystem with a relative abundance of 23.1%. Comparison of species similarities between the zones, revealed 45%, similarity between Western zone and high rainfall zone; 33% similarity between Cauvery delta zone and high rainfall zone and 27% between Western zone and Cauvery delta zone.

(Hymenoptera: Pteromalidae), observed parasitising a lymantrid on sugarcane is described from India. A key to the species of Anisopteromalus from the Indian subcontinent is also provided.

A fungal-like organism associated with a wasp (Hymenoptera: Pteromalidae) in Dominican amber.
Journal of invertebrate pathology, 2012Co-Authors: George Poinar, Joseph W. SpataforaAbstract:Abstract A fungal-like organism emerging from a parasitic wasp (Hymenoptera: Pteromalidae) in Dominican amber is characterized. The fossil consists of a white sclerotium-like formation in the wasp’s abdomen and a flattened clava-like structure with an ovoid terminus emerging from the sclerotium-like formation. The ovoid terminus bears a protruding elliptical appendix. The fossil, which is characterized by its small size, somatic configuration, Pteromalid host and presence in Dominican amber, cannot be placed with assurance in any extant fungal group at this time.

A North American invasive seed pest, Megastigmus spermotrophus (Wachtl) (Hymenoptera: Torymidae): Its populations and parasitoids in a European introduction zone
Biological Control, 2008Co-Authors: Anne-catherine Mailleux, Alain Roques, Jean Marc Molenberg, Jean-claude GrégoireAbstract:egastigmus spermotrophus (Hymenoptera: Torymidae) is a seed pest of Douglas-fir (Pseudotsuga menziesii) in its natural range of North America. Along with seeds, this invading species was accidentally introduced to Europe where it became the major pest in Douglas-fir seed orchards and stands. The high rates of seed parasitism observed in Europe were first ascribed to a reduced control by natural enemies which apparently did not followed M. spermotrophus from their native American range. However, our survey showed that the parasitoid censuses carried out so far were incomplete. Several other chalcid parasitoid species were present in the stands surveyed in Belgium. Four parasitoid species emerged from Douglas-fir seeds infested by the Douglas-fir seed chalcid. Two Pteromalids of North American origin, Mesopolobus spermotrophus and Mesopolobus americus, were dominant whereas a few specimens of an eupelmid, Brasema urozonus, and of another Pteromalid, Anogmus hohenheimensis, were also observed. Our results strongly suggest that the previous evaluations of parasitoids populations were biased by an inadequate timing in the censuses.

Cleptoparasitism increases the host finding ability of a polyphagous parasitoid species, Rhopalicus tutela (Hymenoptera: Pteromalidae)
Behavioral Ecology and Sociobiology, 2003Co-Authors: Evelyne Hougardy, Jean-claude GrégoireAbstract:Host finding abilities were investigated in the braconid Coeloides bostrichorum and the Pteromalid Rhopalicus tutela, two ectoparasitoid wasps attacking the late instar of the bark beetle Ips typographus. Under laboratory conditions, important differences in the host-searching behaviour of these species were found, R. tutela being highly mobile as compared to C. bostrichorum. In the presence of C. bostrichorum, R. tutela behaved as a cleptoparasitoid, displacing the females from their oviposition sites and stealing the hosts previously located by the braconid. This behaviour facilitated host finding in R. tutela and could partly explain the relative success of the polyphagous R. tutela when occurring with the more specialised C. bostrichorum.

Melittobia digitata Dahms (Hymenoptera: Eulophidae) and Monodontomerus mexicanus Gahan (Hym.: Pteromalidae) on a nest of Trypoxylon (Trypargilum) mexicanum (Saussure) (Hym.: Crabronidae) collected near Xalapa, Veracruz, Mexico.
ACTA ZOOLÓGICA MEXICANA (N.S.), 2010Co-Authors: J. M. González, C. Sormani, S. B. VinsonAbstract:In a mud-nest built by Trypoxylon mexicanum, collected near Xalapa, Veracruz, Mexico, we recorded the presence of two parasitoids Monodontomerus mexicanus (Pteromalidae) and Melittobia digitata (Eulophidae), and one ant: Solenopsis geminata (Formicidae). The Pteromalid is reported for the first time from Veracruz while the eulophid is reported from Mexico attacking another hymenopteran. The presence of an ant inside an empty cell is possibly just a coincidence.
