“…From analysis of the 28S ribosomal RNA from the genus Hybrizon Fallén, 1813, it may be concluded that the Hybrizoninae are at a basal position of the Ichneumonidae-lineage (Belshaw et al 1998;Quicke et al 2000;Belshaw and Quicke 2002), but Gillespie et al (2005) documented the unusual structure of 28S in Hybrizon, which makes alignment difficult. Quicke et al (2009) found that Hybrizon likely is a derived subfamily within the ophioniformes-group of the Ichneumonidae, which agrees with the derived morphology of the Hybrizoninae.…”

“…Gauld (1988) hypothesized that koinobiont endoparasitism arose in Braconidae on coleopteran or lepidopteran hosts, while in Ichneumonidae it probably arose mainly on symphytan hosts. In the most recent phylogeny, the monophyletic Ichneumonidae: Ophioniformes (which contain the majority of Lepidoptera-attacking koinobiont Ichneumonidae) also have symphytan parasitoids near the base of the clade (Quicke et al 2009). Therefore, we hypothesize that more generalist species or lineages of koinobiont Ichneumonidae managed to switch from symphytan to lepidopteran hosts, and they have kept their broader host ranges since.…”

“…Terrestrial food webs of plants, herbivores and their natural enemies harbour much of global biodiversity (Hamilton et al 2010;Price 2002), including many parasitoids (Godfray 1994;Quicke 1997). Understanding of the mechanisms maintaining this enormous diversity requires quantitative data on host-parasitoid food webs, especially from the tropics where these food webs are poorly known (Godfray et al 1999).…”

Parasitism rate, parasitoid community composition and host specificity on exposed and semi-concealed caterpillars from a tropical rainforest

et al. 2013

The processes maintaining the enormous diversity of herbivore-parasitoid food webs depend on parasitism rate and parasitoid host specificity. The two parameters have to be evaluated in concert to make conclusions about the importance of parasitoids as natural enemies and guide biological control. We document parasitism rate and host specificity in a highly diverse caterpillar-parasitoid food web encompassing 266 species of lepidopteran hosts and 172 species of hymenopteran or dipteran parasitoids from a lowland tropical forest in Papua New Guinea. We found that semi-concealed hosts (leaf rollers and leaf tiers) represented 84 % of all caterpillars, suffered a higher parasitism rate than exposed caterpillars (12 vs. 5 %) and their parasitoids were also more host specific. Semi-concealed hosts may therefore be generally more amenable to biological control by parasitoids than exposed ones. Parasitoid host specificity was highest in Braconidae, lower in Diptera: Tachinidae, and, unexpectedly, the lowest in Ichneumonidae. This result challenges the long-standing view of low host specificity in caterpillar-attacking Tachinidae and suggests higher suitability of Braconidae and lower suitability of Ichneumonidae for biological control of caterpillars. Semi-concealed hosts and their parasitoids are the largest, yet understudied component of caterpillar-parasitoid food webs. However, they still remain much closer in parasitism patterns to exposed hosts than to what literature reports on fully concealed leaf miners. Specifically, semi-concealed hosts keep an equally low share of idiobionts (2 %) as exposed caterpillars.

“…Th ey regarded the genus Pseudorhyssa Merrill as the sister group to all other Poemeniinae and erected the tribe Pseudorhyssini. Pseudorhyssa is somewhat aberrant among the subfamily and Quicke et al (2009) noted that it might deserve its own subfamily status. Th e apparently primitive genus, Rodrigama, was known from only a single species, R. gamezi, described from Costa Rica.…”

Discovery of Rodrigama Gauld in the Old World, with description of two new species (Hymenoptera, Ichneumonidae, Poemeniinae)

Two new species of the genus Rodrigama Gauld are described: R. gauldi sp. n. from Ryukyus, Japan and R. takakuwai sp. n. from Taiwan. Th e genus Rodrigama was known from a single Costa Rican species and these new species are the fi rst representatives of the genus in the Old World. Th e distribution of these species in the Palaearctic/Oriental Region reinforces the hypothesis that the Poemeniinae originated in the north temperate region and diversifi ed into tropical regions, and that the Costa Rican R. gamezi is a relict of a group that once had a wider distribution. A key to the species of the genus is provided.
