Study of the genus Platylabus Wesmael, 1845 (Hymenoptera: Ichneumonidae) in north of Iran, with a new record for the Middle East [PDF]

open access: yesJournal of Insect Biodiversity and Systematics, 2018
The present study is based on the material collected from Alborz and Guilan provinces of Iran during March to November 2010 and 2011. Three species of the genus Platylabus Wesmael were collected and identified, of which Platylabus orbitalis (Gravenhorst,

Biology of Rhembobius quadrispinus (Hymenoptera: Ichneumonidae): Pupal parasitoid of saprophagous species of syrphids (Diptera: Syrphidae)

open access: yesEuropean Journal of Entomology, 2014
Little is known about the life cycle of Rhembobius parasitoids (Hymenoptera: Ichneumonidae). Known host records are mainly from saprophagous species of hoverflies of the tribe Eristalini (Diptera: Syrphidae), whose larvae develop in a wide range of ...

Effect on Constant Versus Fluctuating Temperature Regimes on \u3ci\u3eBathyplectes Curculionis\u3c/i\u3e (Hymenoptera: Ichneumonidae) Activity [PDF]

open access: yes, 2017
Individual female Bathyplectes curculionis parasites were exposed to either a series of constant or fluctuating temperature regimes and supplied with a new group of host Hypera postica larvae every day.

Floral resource strips enhance parasitoid abundance and diversity in apple orchards and promote agroecological advances in a South African biosphere reserve

open access: yesInsect Conservation and Diversity, EarlyView.
Floral resource strips within apple orchards increased parasitoid abundance and influenced community composition, enhancing local biodiversity in the Kogelberg Biosphere Reserve's transition zone. Ruderal and natural fynbos habitats supported higher parasitoid richness and abundance, emphasising the importance of conserving semi‐natural habitats ...

Study of the tribe Heresiarchini (Hymenoptera: Ichneumonidae, Ichneumoninae) in northern Iran, with a new record for the Middle East [PDF]

open access: yesJournal of Insect Biodiversity and Systematics, 2018
In this survey the tribe Heresiarchini (Hymenoptera: Ichneumonidae, Ichneumoninae) of Alborz and Guilan provinces (Iran) was taxonomically studied. The specimens were collected using Malaise traps during March to November 2010.

Assessing species richness of the subfamily Campopleginae (Hymenoptera, Ichneumonidae) community in Darab damask rose rain-fed plain, Fars province, Iran [PDF]

open access: yesJournal of Insect Biodiversity and Systematics, 2023
Here, the species richness of Campopleginae, a diverse subfamily of the Darwin wasps was studied in an almost organic damask rose plain located at 2600 m a.s.l., the south of Iran.

First records of Acrotaphus fuscipennis (Cresson) and of A. tibialis (Cameron) from the United States (Hymenoptera: Ichneumonidae) [PDF]

open access: yes, 2005
Acrotaphus fuscipennis (Cresson), distinctive because of its black wings and bright red body, is recorded for the first time from the United States. It was reared from araneid spiders collected in Florida, which constitutes the first host record for this

The evolution of gregariousness in parasitoid wasps [PDF]

open access: yes, 1998
Data are assembled on the clutch-size strategies adopted by extant species of parasitoid wasp. These data are used to reconstruct the history of clutch-size evolution in the group using a series of plausible evolutionary assumptions.

Arthropod niche differentiation linked to grazing‐induced sward islets in intensively managed agricultural pasture

open access: yesInsect Conservation and Diversity, EarlyView.
In a given number of samples, grassland sward islets contain more species of arthropods than the surrounding sward. When corrected for abundance, there is no difference in species richness, suggesting that the effect of islets might purely be to concentrate arthropods. The community structure differences indicated by non‐metric multidimensional scaling

Distribution models of polysphinctine parasitoid wasps (Hymenoptera: Ichneumonidae) reveal sampling bias and flag potentially overlooked host interactions

open access: yesInsect Conservation and Diversity, EarlyView.
We quantified the geographical overlap between parasitoid wasps and their known host spiders. We could assess which parasitoid species have more limited information about their interactions and are subject to geographical survey bias. We generated sampling bias maps to assist other researchers in identifying where the main sampling gaps are.
