RNA Viruses in Parasitoid Wasps

, 2012
This chapter describes the different RNA viruses that have been detected at least once in parasitoid wasps. It could be wondered whether the other families of parasitoids are really absent, or if this is due to the fact that inadequate techniques were used to detect viruses.

Effects of non‐host traces on behavioural responses of an egg parasitoid to substrate‐borne semiochemicals in a multi‐herbivore scenario

Ecological Entomology, EarlyView.
In open arena assays, the response of the egg parasitoid Trissolcus basalis to substrate‐borne semiochemicals left by the host Nezara viridula was affected by the non‐host Spodoptera littoralis. Non‐host larval traces reduced T. basalis residence time spent on walking traces from gravid N. viridula females but did not affect responses to walking traces

Report of Diglyphus poppoea (Hym.: Eulophidae) from Iran [PDF]

نامه انجمن حشره‌شناسی ایران, 2008
A survey was conducted to identify parasitoids of leafminers in Shiraz region during spring 2005. The specimens of the Eulophid parasitoid wasp, Diglyphus poppoea Walker, were reared from wheat leaves infested by Agromyza ambigua Fallén (Dip ...

Parasitic wasp‐associated polydnavirus and venom affect arthropod community assembly on wild cabbage via the caterpillar host

Ecological Entomology, EarlyView.
Cotesia glomerata polydnavirus and venom, either alone or in combination, affect colonisation by members of the arthropod community in a natural field setting. Plants damaged by P. brassicae injected with both polydnavirus and venom were colonised more often by Mamestra brassicae caterpillars, Myzus persicae aphids and aphid parasitoids compared to ...

Maternal factors from a parasitoid wasp mediate hyperparasitoid attraction to parasitized caterpillars

Ecological Entomology, EarlyView.
The parasitoid‐associated polydnavirus CgPDV, but not venom alone, significantly increases the attractiveness of Pieris brassicae caterpillars to the hyperparasitoid Baryscapus galactopus at close range. Naturally parasitized caterpillars elicit stronger hyperparasitoid attraction than any injection treatment, indicating that additional factors beyond ...

Imidacloprid Alters Activity and Responses to a Visual Predator Stimulus in Aussie Bronze Jumping Spiders (Helpis minitabunda, Araneae, Salticidae)

Ethology, EarlyView.
A field‐recommended concentration of a commercial imidacloprid formulation reduced open arena activity and slowed climbing in the jumping spider Helpis minitabunda. Exposed spiders still detected a looming predator stimulus, but their responses were reduced.

Transfer of a chromosomal Maverick to endogenous bracovirus in a parasitoid wasp

, 2011
International audienceBracoviruses are used by parasitoid wasps to allow development of their progeny within the body of lepidopteran hosts. In parasitoid wasps, the bracovirus exists as a provirus, integrated in a wasp chromosome.

Hyperparasitic showdown: Sclerodermus cereicollis, a non-aggressive but surprisingly secondary hyperparasitoid

Journal of Entomological and Acarological Research
This study investigates the dynamics of hyperparasitism within the Bethylidae family, focusing on the interaction between Sclerodermus cereicollis and Goniozus legneri, two parasitoid wasp species characterized by different sociality and aggressivity ...

Fragmented grasslands in different landscape structures provide different opportunities for cavity‐nesting Hymenoptera

Insect Conservation and Diversity, EarlyView.
Grassland fragmentation effects on cavity‐nesting Hymenoptera are habitat‐specific. Isolated sand steppe fragments are associated with higher brood‐cell abundance. In loess steppes, higher flower frequency increases bee brood‐cell production and parasitoid activity. Abstract The global decline in insects threatens ecosystem functioning, but the drivers
