Encapsulation and melanisation are innate immune reactions of insects against foreign intruders such as parasitoids. In an earlier study, we observed that immature life stages of the endoparasitoid Tranosema rostrale (Hymenoptera: Ichneumonidae) parasitizing Choristoneura fumiferana (Lepidoptera: Tortricidae) larvae experienced higher mortality due to encapsulation and melanisation when reared at high (30°C) than at lower (10°C, 20°C) temperatures. Downregulation of T. rostrale polydnavirus genes in parasitized hosts and upregulation of two genes involved in the spruce budworm's melanisation process were identified as likely contributors to parasitoid mortality at high temperature...

A new genus, Verruca Sheng Sun gen. nov., of the ichneumonid tribe Atrophini, subfamily Banchinae is described for one new species, Verruca dentia Sheng Sun, sp. nov. The species was collected from Shandong and Jiangxi Provinces, situated near the northern border of the Oriental part of China. The new genus is placed within the existing key to genera.

The Oriental species of the genus Eridolius Förster, 1869 are reviewed, and a new species, E. xui Reshchikov, sp. nov. is described from Southern China. This is the seventh record of the genus from the Oriental region. The new species can be distinguished from all other Oriental species of the genus by its lower mandibular tooth longer than upper one, face entirely black, and coxae, hind femur and most of metasoma reddish. An illustrated key to the Oriental species of the genus is provided. Eridolius guptai is recorded for the first time from Lao and E...

Brachyzapus Gauld Dubois, 2006 is a small genus belonging to the Polysphincta genus-group of the subfamily Pimplinae, with nine known species worldwide (Uchida Momoi, 1958; Yu et al., 2012; Pham et al., 2012). The genus can be recognized by twisted mandibles, a very weakly convex and rather long clypeus with quite well-defined angulation laterally, elongate lower face, sparse pubescence on the eyes, hind coxal cavities separated from the metasoma insertion by a very strong sclerotized bridge, and the lack of a basal lobe on the ovipositor (Gauld Dubois, 2006)...

The genus Triancyra Baltazar, 1961 and two species, viz. Triancyra aurea Wang Hu, 1992 and Triancyra graptothoracalis Wang Huang, 1992, are reported for the first time from Vietnam. In addition, three species are described as new: Triancyra acuta sp. nov., and Triancyra mystaxa sp. nov. from Dak Lak Province in Central Highlands, and Triancyra cucphuongensis sp. nov. from Ninh Binh Province in northern Vietnam. A key for all five Vietnamese Triancyra is also compiled.

The Tersilochinae fauna of Finland is critically revised (except subgenera Tersilochus Holmgren and Euporizon Horstmann). Tersilochinae in two principal Finnish ichneumonid collections, the Finnish Natural History Museum LUOMUS (University of Helsinki) and the private collection of R. Jussila (Turku), have been examined. Thirteen genera and 61 species are found to occur in Finland, including one new species, Barycnemis finnora Khalaim, sp. nov. The Nearctic genus Ctenophion Horstmann is recorded from Finland, as well as from the Palaearctic region, for the first time...

A new species, Misetus strumiai sp. n., from the island of Montecristo (Italy, Tuscany) is described and illustrated. The new species is characterized by having the clypeus with a small median tooth, metasomal tergite II almost entirely smooth and polished, and extensively red body color (except for black head). A comparative diagnosis is provided in order to distinguish the new taxon from the other known species of the genus Misetus Wesmael, 1845.

The taxonomic limits of the Neotropical genus Dotocryptus Brèthes are reviewed. The genus is characterized mainly by the very long ovipositor, at least 2.2× as long as hind tibia; apex of ovipositor distinctly depressed, ventral valve expanded, and overlapping dorsal valve as a sheath; and mandible long with ventral tooth longer than dorsal one. A new species, Dotocryptus arcadius sp. nov., from Colombia is described and illustrated. The new species can be diagnosed mainly by the head and mesosoma with multiple whitish marks; epicnemial carina reaching 0...

Parasitoid organisms can manipulate the morphology, physiology and/or behavior of their hosts to increase their own survival (Moore 2002; Korenko et al. 2015a). Wasps of the Polysphincta genus-group sensu Gauld Dubois, 2006 (hereafter polysphinctine wasps) are well known to act exclusively as koinobiont ectoparasitoids of spiders (Gauld Dubois 2006). The host range of these wasps is remarkably narrow and often species-specific; individuals of some polysphinctine genera (e.g. Hymenoepimecis, Acrotaphus) usually attack orb-weaver spiders (Pádua et al...

Accurate egg placement into or onto a living host is an essential ability for many parasitoids, and changes in associated phenotypes, such as ovipositor morphology and behaviour, correlate with significant host shifts. Here, we report that in the ichneumonid group of koinobiont spider-ectoparasitoids ("polysphinctines"), several putatively ancestral taxa (clade I here), parasitic on ground-dwelling RTA-spiders (a group characterised by retrolateral tibial apophysis on male palpal tibiae), lay their eggs in a specific way...

Naivasha thorn tree, Acacia xanthophloea, is grown for foliage, timber, shade and rehabilitation of soils in areas with high water tables in Kenya. Its production is threatened by insect pests, which cause major losses. Very little is documented on wood-boring beetles which cause considerable economic damage to lumber used in a variety of applications, and little is known about their natural enemies in Kenya. We conducted the study to evaluate the occurrence of wood-boring beetles on A. xanthophloea in two different regions of Kenya...

BACKGROUND: Multispectral (MS) imaging system is a non-destructive method that has potential in reducing labour and time required for quality control in the production of beneficial arthropods like the parasitoid Bathyplectus curculionis. In Denmark, a project is focusing on possible use of B. curculionis in augmentative control of Hypera weevil pests in white clover seed production where cocoons of the parasitoid remain as a by-product of seed processing. Only a fraction of the by-product contains live parasitoid larvae and requires an effective method for sorting the live cocoons for later augmentative control of the pest...

Roberto Romani, Sara Ruschioni, Paola Riolo, Nunzio Isidoro
Pimplinae are parasitoids belonging to the family Ichneumonidae that attack and develops inside hidden host; female wasps evolved a peculiar host recognition strategy, that involves the use of self-produced vibrations which are transmitted through the antennae on the substrate and perceived back as an echo using the leg subgenual organ. In this study we investigated, using both scanning and transmission electron microscopy, the antennal tips of a few Pimplinae. In all the investigated species, the antennal tips present peculiar apical pegs with different shape and number, often defining a flattened sole devoid of other antennal structures, such as sensilla...

Botanical insecticides (BIs) are considered a valuable alternative for plant protection in sustainable agriculture. The use of both BIs and parasitoids are presumed to be mutually compatible pest management practices. However, there is controversy on this subject, as various studies have reported lethal and sublethal effects of BIs on hymenopteran parasitoids. To shed new light on this controversy, a meta-analytic approach of the effects of BIs on adult mortality, parasitism, and parasitoid emergence under laboratory conditions was performed...
