The four major biological strategies of ichneumonoid parasitoids, koinobiont and idiobiont, ecto-and endoparasitism, are discussed and the evolutionary radiations of the two families Ichneumonidae and Braconidae compared in an attempt to relate differences in patterns of host utilization to differences in evolutionary history. The most primitive members of both families are idiobiont ectoparasitoids of hosts concealed in plant tissue. Idiobiont ectoparasitic braconids are all still primarily… 
The evolutionary pattern of host use in the Bombyliidae (Diptera): a diverse family of parasitoid flies
An evolutionary scenario progressing from an ancestral substrate-zone free-living predator to ectoparasitoid, a broadening of host range to include the consumption of orthopteran egg pods, and the independent development of endopar asitism in two lineages is proposed.
Observation of Aneurobracon philippinensis (Hymenoptera: Braconidae) Immatures Shows How Koinobiont Offspring Flexibly Adjust Their Development to Host Growth
Results suggest that the first-instar period of the Parasitoid larvae functions as an adjusting period to synchronize the parasitoid and host developmental stages and that koinobiosis plays an important role in utilizing the final instar of A. transecta as a resource.
Host-parasitoid associations in Strepsiptera.
Aspects of virulence, heterotrophic heteronomy in the family Myrmecolacidae, cryptic species, genomics, immune response, and behavior of stylopized hosts are discussed in this chapter.
Cyclosa omonaga (Araneae: Araneidae), an Alternative Host of the Spider Ectoparasitoid Reclinervellus nielseni (Hymenoptera: Ichneumonidae), with Notes on Behavioural Manipulation
Abstract Parasitism upon Cyclosa omonaga (Araneidae) by the ichneumonid ectoparasitoid Reclinervellus nielseni is reported for the first time, based on molecular identification, corroborating that R.
Phylogenomics of Ichneumonoidea (Hymenoptera) and implications for evolution of mode of parasitism and viral endogenization
The data suggest many transitions between parasitoid life history traits across the whole superfamily, including two subfamilies within Ichneumonidae that have polydnaviruses that are supported as distantly related, providing strong evidence for two independent acquisitions of ichnoviruses.
Unexpected Use of Pupal Stage of a Lepidopteran Host by the Ectoparasitoid Wasp Agrothereutes lanceolatus (Hymenoptera: Ichneumonidae)
The evidence is given that Agrothereutes lanceolatus, a solitary ectoparasitoid wasp, can exceptionally parasitize host pupae, succeeding to extend its host range to pupal hosts that have a hardened cuticle, enabling it to be a common and widespread polyphagous species among ectoparsitic Cryptinae.
Host Location by Ichneumonid Parasitoids is Associated with Nest Dimensions of the Host Bee Species
It is proposed that these parasitoids use vibrational sounding as a host location mechanism and that they are able to assess host nest dimensions and choose those which may provide them with a higher fitness.
Host specificity testing and suitability of the parasitoidMicroctonus hyperodae (Hym.: Braconidae, Euphorinae) as a biological control agent ofListronotus bonariensis (Col.: Curculionidae) in New Zealand
A review of the habitats of the native weevil and target pest populations indicated that refugia would probably exist for native alpine species, and the parasitoid was recommended as suitable for release in view of its relatively oligophagous behaviour.


Parasitiods Utilizing the Same Host: Adaptive Nature of Differences in Size and Form
Comparison of ovipositor lengths indicates how similar the species can be in size, and therefore larval food exploitation, before competitive displacement prevents coexistence.
The parasitoid complex of Euxoa ochrogaster (Guenee) (Lepidoptera: Noctuidae)
The purpose of this study is to provide a method of identifying some of the immature stages of the parasitoids of the redbacked cutworm, a well-known, destructive ground cutworm native to the prairie provinces of Canada.
Some factors affecting the composition of tropical ichneumonid faunas
It is postulated that koinobionts have the capability of being able to locate sparse hosts, but as they host-search in flight, a prolonged daytime host- searching period in the tropics would expose them to a high level of predation pressure, so it is suggested that sparse hosts may be located more easily at night and more habitats may be climatically suitable for ichneumonid activity when they are not subject to direct sunlight.
Latitudinal gradients in ichneumonid species‐richness in Australia
New data from Australia support previous suggestions that the Ichneumonidae as a whole is not more species‐rich in the tropics than the group is in temperate regions, and it is suggested that this may be a result of a larger proportion of the suitable host larvae being nocturnally active.
A comparative study of the relationship between host size and brood size in Apanteles spp. (Hymenoptera: Braconidae)
The possible role of evolutionary constraints to adaptive progeny allocation in Apanteles is discussed, and there is a relative shortage of gregarious species on small hosts, and a relative excess of solitary species on large hosts.

Aspects of the ecology of siricid woodwasps (Hymenoptera: Siricidae) in Europe, North Africa and Turkey with special reference to the biological control of Sirex noctilio F. in Australia.
Data is presented on distribution, flight periods and sexratios, factors leading to the susceptibility of timber to siricid infestation and the types of timber and host tree species infested, and levels of parasitism by the various parasitoid species.
Casinaria, a paraphyletic ichneumonid genus (Hymenoptera), and a revision of the Australian species
The Australian species of the campoplegine ichneumonid genus Casinaria are revised and characters supporting the holophyly of the genus could not be found, suggesting thatCasinaria, as currently recognized, may either be paraphyletic or polyphyletic.
On Philopsyche abdominalis Morley (Hym.: Ichneumonidae), a parasite of Acanthopsyche junodi Heylaerts (Lep.: Psychidae)
The main insect pest of commercially-grown wattles (Acacia mollissima Willd.) in South Africa is the leaf-eating larva of the wattle bagworm Acanthopsyche junodi Hey\. The original host plants of
The biology of Adelognathus granulatus Perkins (Hym., Ichneumonidae) a parasitoid of the small gooseberry sawfly, Pristiphora pallipes (Lep.) (Hym., Tenthredinidae)
Parasitoid larval development was very rapid, (less than 1 week) followed by pupation away from the dead host, and the pupal period was about 2 weeks, with no obligatory diapause.
