Parasitoid‐mediated indirect interactions between unsuitable and suitable hosts generate apparent predation in microcosm and modeling studies

open access: yesEcology and Evolution, Volume 11, Issue 6, Page 2449-2460, March 2021., 2021
We investigated indirect interactions that can occur when a single parasitoid species attacks two aphid species that differ in their suitability for parasitism. Laboratory studies showed that the presence of unsuitable hosts indirectly increased populations of suitable hosts through an egg sink experienced by the shared parasitoid, and a parameterized ...

Morphometric indicators for quality assessment in the aphid parasitoid, Lysiphlebus fabarum (Braconidae: Aphidiinae)

open access: yesEuropean Journal of Entomology, 2013
Body size is a standard criterion of quality control in insect rearing and often assumed to correlate with fitness in parasitoid wasps, but various metrics of body size can be used.

Sex ratio shift caused by hyperparasitism in the solitary parasitoid Lysiphlebus hirticornis (Hymenoptera: Braconidae: Aphidiinae)

open access: yesEuropean Journal of Entomology, 2005
We examined the influence of offspring mortality caused by hyperparasitism on the secondary sex ratio of Lysiphlebus hirticornis Mackauer, a solitary endoparasitoid of the aphid Metopeurum fuscoviride Stroyan, in the field. Females of L.

Variations in community assemblages and trophic networks of aphids and parasitoids in protected crops

open access: yesEcosphere, Volume 11, Issue 5, May 2020., 2020
Abstract Greenhouse crops are thought to be simplified ecosystems because they often consist of monocultures that are relatively isolated from their environment. However, insect pests are still able to colonize these protected crops, which threaten their yields.

Studies on the identity of the parasitoids Aphidius colemani and Aphidius transcaspicus (Hymenoptera: Braconidae)

open access: yesEuropean Journal of Entomology, 2009
The taxonomic status of the aphid parasitoid Aphidius colemani Viereck has been questioned, especially in regard to Aphidius transcaspicus Telenga (Hymenoptera: Braconidae). The genetic association between A. colemani and A.

Distribution and diversity of wheat aphid parasitoids (Hymenoptera: Braconidae: Aphidiinae) in Iran

open access: yesEuropean Journal of Entomology, 2008
Eleven species of parasitoids were found to attack 7 species of wheat aphids in Iran. The Simpson's Index of diversity (D) used to compare the aphidiine diversity in various cereal crop systems in geographically different regions of Iran ranged from 0 ...

open access: yesEuropean Journal of Entomology, 2002
In the mating behaviour of Aphidius ervi Haliday the antennae play a pivotal role in partner recognition and acceptance. Mating failure was always observed when antennal contact was experimentally prevented. The male of A.
