“…Here we focus on two of the most extensively studied subfamilies in the Neotropical region, Pimplinae and Rhyssinae (e.g. Porter, ; Gauld, ; Gauld et al ., , ; Sääksjärvi et al ., ; Gómez et al ., , , ; Gómez & Yabar, ).…”

The old idea that parasitoid wasps (Ichneumonidae) show an inverse latitudinal diversity gradient has recently been challenged, but how ichneumonid species richness varies across the globe is still not well understood. We carried out field inventories in 21 sites on three continents to clarify this question, focusing on the subfamilies Pimplinae and Rhyssinae. Our total sampling effort was 628 Malaise trap months and the total catch exceeded 65 000 individuals. Our main focus was in two intensively inventoried areas in Amazonia, together yielding 257 Malaise trap months and 26 390 ichneumonid individuals. To expand the scope and assess global species diversity patterns of the Pimplinae and Rhyssinae, we compiled published species lists from a total of 97 study localities around the world. The highest observed species richness in any locality, 105 species, was found in one of our field sites in Peruvian Amazonia. None of the other localities reported more than 70 species, even the ones with a sampling effort comparable to ours. Despite the local thoroughness of our field inventories in Amazonia, data analyses indicated that a substantial proportion of the parasitoid wasp species occurring in each site remained unobserved. The highest local species richness values were reported from the tropics. Nevertheless parasitoid wasps are still too sparsely sampled to draw solid conclusions about whether or not their species richness follows a particular latitudinal trend, and if so, where their richness peaks.

Abstract. We provide a list of the Pimplinae from the Estação Ecológica dos Caetetus, São Paulo state, Brazil. A total of 286 specimens belonging to 17 species in 10 genera were collected from December 2002 to May 2004. Pimpla and Neotheronia were the most abundant genera with 45% and 10% specimens respectively. Fourteen species of Pimplinae were recorded for the first time from São Paulo state and 3 of them, Neotheronia charli, N. cherfasi and N. lizzae, were recorded for the first time from Brazil. We also provide diagnosis and images of the species.

“…Lastly, all three pupal 'generalists' found in the field study were known to be facultative hyperparasitoids (C. albifrons: Arthur, 1958;Peck, 1963;Miall et al, 2014;Scambus sp. : Gauld, 1991;Gomez & Yabar-Landa, 2015; Itoplectis spp. : Ueno, 1997 Miall et al, 2014), the window of opportunity for these parasitoids to feed, host-search, and attack is significantly longer than that of D. pulchellus (JM, unpublished data), as observed by Cusumano et al, (2013) in a different facultative hyperparasitoid/primary parasitoid system.…”

The parasitoid community associated with the invasive leek moth, Acrolepiopsis assectella (Zeller) (Lepidoptera: Acrolepiidae): can conservation biological control benefit an introduced classical biological control agent in North America?

The leek moth is a European pest of Allium spp. established near Ottawa, Ontario, Canada in the early 1990's. Its spread throughout eastern Canada and into the northeastern United States represents the potential for significant economic losses to Allium growers. Using a life-table approach, I aimed to determine if resource supplementation would influence the species composition, relative abundance and hostkilling ability of indigenous parasitic wasps in the leek moth system and the classical biological control agent, Diadromus pulchellus. In greenhouse cages, adding buckwheat to a sugar-deprived system increased the longevity, and parasitism levels of D. pulchellus; however, a similar effect was measured on the facultative hyperparasitoid, Conura albifrons. In the field, the parasitoid species composition was the same in both buckwheat-supplemented and standard leek plots; however, the relative abundance of the parasitoid community differed between the standard and resource-enriched plots. These studies provide insight into how conservation biological control may affect classical biological control. viii
