Uncovering Norway: Descriptions of Four New Aphidiinae Species (Hymenoptera, Braconidae) with Identification Key and Notes on Phylogenetic Relationships of the Subgenus Fovephedrus Chen. [PDF]

Insects
With only 33 reported species, Norway ranks among the European countries with the lowest documented diversity of parasitoids from the subfamily Aphidiinae.

A Review of Aphid Parasitoids, with an Identification Key to the Genera of Economic Importance. [PDF]

Insects
Agriculture plays an essential role in meeting global food demand, and so effective pest control is crucial. Aphids (Hemiptera: Aphididae) are a significant problem for many crops worldwide, and cause crop losses.

Prospects for habitat management to suppress vegetable pests in Australia

Austral Entomology, Volume 61, Issue 1, Page 3-28, February 2022., 2022
Abstract Habitat management is an ecologically based approach to suppress pest densities, utilising properties of non‐crop vegetation to improve the impact of natural enemies or to directly affect pest behaviour. Research in this approach has escalated dramatically this century, extending to uptake in some crops, but adoption in Australia has been ...

What feeds on Quercus ilex L.? A biogeographical approach to studying trophic interactions in a Mediterranean keystone species

Diversity and Distributions, Volume 28, Issue 1, Page 4-24, January 2022., 2022
Abstract Aim Holm oak (Quercus ilex L.) is regarded as a keystone plant species. Trophic interactions may affect the distribution and abundance of phytophagous species, but the number of arthropod species that use holm oak as a food resource and their levels of host specificity are not yet known.

Strong genotype‐by‐genotype interactions between aphid‐defensive symbionts and parasitoids persist across different biotic environments

Journal of Evolutionary Biology, Volume 34, Issue 12, Page 1944-1953, December 2021., 2021
Environmental variation may affect the outcome of host‐parasite interactions. We show that aphid host plants—here from left to right Beta vulgaris, Chenopodium album and Vicia faba—quantitatively influence parasitism success of a parasitoid wasp on symbiont‐protected aphids, however without altering the strong G × G interactions occurring between ...

Chromosome‐level genome assembly of the aphid parasitoid Aphidius gifuensis using Oxford Nanopore sequencing and Hi‐C technology

Molecular Ecology Resources, Volume 21, Issue 3, Page 941-954, April 2021., 2021
ABSTRACT Aphidius gifuensis is a parasitoid wasp that has been commercially bred and released in large scale as a biocontrol agent for the management of aphid pests. As a highly efficient endoparasitoid, it is also an important model for exploring mechanisms of parasitism.

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

Ecology 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)

European 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)

European 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.
