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

With only 33 reported species, Norway ranks among the European countries with the lowest documented diversity of parasitoids from the subfamily Aphidiinae. The "MUST Malaise" project, carried out by Museum Stavanger in Norway, aimed to assess insect abundance and biodiversity and create a reference base for future studies. The preliminary results of our study revealed four species new to science, indicating that the current number of recorded species in Norway is significantly lower than the actual diversity.

The genetic characterization of grapevines prospected in old Serbian vineyards reveals multiple relationships between traditional varieties of the Balkans.

Serbia preserves a high number of local grape varieties, which have been cultivated across the country for centuries. Now, these ancient varieties are in the spotlight, and there is a global trend towards their recovery and characterization because they can revitalize regional, national and international grape and wine sectors. In addition, their genetic study can be useful to find new pedigree relationships to reveal how local varietal assortment evolved over time.

It's time for Africa - hidden diversity of the species group (Hymenoptera, Braconidae, Aphidiinae) south of the Sahara.

is an important biological control agent, used in greenhouses and open fields against aphid pests. Despite this economical importance, , along with and , has gone through a complex taxonomical history. The three species have only recently gained status as separate species again, comprising the morphologically defined species group.

A new species of genus (Hymenoptera, Braconidae, Aphidiinae) from South Korea.

Background: The genus Haliday, 1833 is a small group which consists of 24 species worldwide. In South Korea, Chang and Youn (1983) recorded one species, Starý & Schlinger, 1967, but the evidence for identification of this species is doubtful and further confirmation is required (personal communication with Prof. Jong-Cheol Paik).

Diversity of parasitoid wasps (Insecta, Hymenoptera) in oilseed rape fields in Serbia.

Background: Oilseed rape is an important crop grown worldwide and used for various purposes, including oil extraction and animal feed. In Europe, there are six major pest species and several other minor pests that can significantly affect oilseed rape production, requiring growers to effectively control them in order to ensure crop yield. The host-parasitoid complexes of these pests have been studied in detail and recorded mainly in western, central and northern Europe.

A genetic history of the Balkans from Roman frontier to Slavic migrations.

The rise and fall of the Roman Empire was a socio-political process with enormous ramifications for human history. The Middle Danube was a crucial frontier and a crossroads for population and cultural movement. Here, we present genome-wide data from 136 Balkan individuals dated to the 1 millennium CE.

Four New Species of Pseudephedrus (Hymenoptera, Braconidae, Aphidiinae) from Chile with a Key to Species Identification.

The following work consists of the description of four new species of the genus Pseudephedrus Starý (Aphidiinae), endemic to South America, associated with endemic callaphidid aphid hosts. The descriptions of the new species are based on new samples from Chile and Argentina. The new species described here are as follows: Pseudephedrus staryi sp.

 sp. nov. (Hymenoptera, Braconidae, Aphidiinae): description of a new aphid parasitoid species with an identification key for species of the genus.

The braconid genus Hincks is a small member of the subfamily Aphidiinae, distributed in Europe and Central Asia. All its species are highly specialized parasitoids of aphids of the genera Koch and, probably, van der Hoeven which are mostly associated with maple and sycamore trees (genus ). Upon examination of specimens from the Naturalis Biodiversity Center, Leiden, we unexpectedly noted unusual variability in morphological characters compared to other known species.

Two new species of subtribe Monoctonina Mackauer from Europe (Hymenoptera, Braconidae, Aphidiinae).

Falciconus hispanicus sp. n. and Monoctonus montenegrinus sp.

Cereal Aphid Parasitoids in Europe (Hymenoptera: Braconidae: Aphidiinae): Taxonomy, Biodiversity, and Ecology.

Cereals are very common and widespread crops in Europe. Aphids are a diverse group of herbivorous pests on cereals and one of the most important limiting factors of cereal production. Here, we present an overview of knowledge about the taxonomy, biodiversity, and ecology of cereal aphid parasitoids in Europe, an important group of natural enemies contributing to cereal aphid control.

Do primary and secondary host plants affect aphid- parasitoid interactions in fruit orchards?

The aim of this study was to investigate how the primary (PHP) and secondary host plants (SHP) in the fruit orchards affect the interactions of aphids and their parasitoids in northwest Turkey during spring and summer 2020 and 2021. In total, 67 tritrophic aphid-parasitoid-host plant interactions, including new association records for Europe and Turkey, were obtained from 16 parasitoid species from the subfamily Aphidiinae (Hymenoptera: Braconidae) reared from 25 aphid species (Hemiptera: Aphididae) on 22 PHP and SHP in the fruit orchards. Also, we evaluated the effect of the PHP and SHP on the parasitoids, aphids and their interactions.

Resolving the Taxonomic Status of Potential Biocontrol Agents Belonging to the Neglected Genus Förster (Hymenoptera, Braconidae, Aphidiinae) with Descriptions of Six New Species.

is a small genus in the subfamily Aphidiinae represented by one species in Europe ( Förster) and by four in Asia ( Chen, Gahan, Pramanik and Raychaudhuri and Pramanik and Raychaudhuri). Although is employed in biological control programs against pest aphids, the last morphological study on the genus was completed over 50 years ago. This study employs an integrative approach (morphology and molecular analysis (COI barcode region)), to examine specimens that were sampled worldwide, including specimens from BOLD database.

Phylogeny of the Subtribe Monoctonina (Hymenoptera, Braconidae, Aphidiinae).

Members of the Monoctonina subtribe have long been neglected in applied studies of the subfamily Aphidiinae, due to their low economic importance, as they do not parasitize pests of cultivated plants. Consequently, data about this group are scarce, including its taxonomy and phylogeny. In the present study, we explore inter- and intraspecific genetic variation of Monoctonina species, including genera Haliday 1833, Starý 1962, Mackauer 1959 and Cameron 1900.

Review of the world Monoctonina Mackauer 1961 (Hymenoptera, Braconidae, Aphidiinae): key for their identification and descriptions of five new species.

The subtribe Monoctonina has long been overlooked when it comes to morphological studies, probably due to the low economic importance of its members. Mainly distributed in high montane areas and forest ecosystems, species of Monoctonina are not often found in large populations and do not parasitize pests of cultivated plants. Our research uncovered five new species belonging to this subtribe (Monoctonus brachyradius sp.

Phylogenetic relationships and subgeneric classification of European species (Hymenoptera, Braconidae, Aphidiinae).

In this study two molecular markers were used to establish taxonomic status and phylogenetic relationships of subgenera and species distributed in Europe. Fifteen of the nineteen currently known species have been analysed, representing three subgenera: Gärdenfors, 1986, Starý, 1958 and Haliday, 1833. The results of analysis of COI and EF1α molecular markers and morphological studies did not support this classification.

Hymenoptera Complex Associated with and spp. in Peach Orchards in Northeastern Spain and Prospects for Biological Control of Aphids.

Aphids are a serious pest for peach crops. They have traditionally been managed with insecticides, but there is increasing concern about the risk that insecticides pose to both humans and the environment. As a first step to use biological control in aphid management, we conducted a 3-year field survey in northeastern Spain to determine which parasitoids and hyperparasitoids were most prevalent on two aphids, (Sulzer) and spp.

Integrative taxonomy of root aphid parasitoids from the genus (Hymenoptera, Braconidae, Aphidiinae) with description of new species.

Species from the genus are obligatory endoparasitoids of root aphids in the Palaearctic. It is known that these species are broadly distributed, parasitizing various aphid hosts and showing great biological and ecological diversity. On the other hand, this group of endoparasitoids is understudied and was thought to be represented by a single species in Europe, viz.

Key for identification of the parasitoids (Hymenoptera: Braconidae: Aphidiinae) of aphids infesting alfalfa in Europe.

Although Aphidiinae parasitoids have been used as agents for biocontrol of alfalfa aphids for more than half a century and have been the subject of numerous ecological investigations, there is an evident lack of systematic studies on the parasitoids of aphids infesting alfalfa in Europe. Here we present an original and up-dated key for identification of both native and invasive Aphidiinae parasitoids attacking aphids that feed on alfalfa in Europe. In total, 20 species are keyed and illustrated with scanning electron micrographs and line drawings.

Species composition and seasonal dynamics of aphid parasitoids and hyperparasitoids in wheat fields in northern China.

Parasitoids are important natural enemies of aphids in wheat fields of northern China, and interest in them has increased in recent years. However, little is known regarding parasitoids of wheat aphids, which has hindered the study and understanding of aphid-parasitoid interactions. In the present study, three primary parasitoids and 15 hyperparasitoids were collected in wheat fields during a 2-year survey in northern China (2014, 2015) and a 2-year investigation at Langfang, Hebei Province (2015, 2016).

An effective molecular approach for assessing cereal aphid-parasitoid-endosymbiont networks.

Molecular approaches are increasingly being used to analyse host-parasitoid food webs as they overcome several hurdles inherent to conventional approaches. However, such studies have focused primarily on the detection and identification of aphids and their aphidiid primary parasitoids, largely ignoring primary parasitoid-hyperparasitoid interactions or limiting these to a few common species within a small geographical area. Furthermore, the detection of bacterial secondary endosymbionts has not been considered in such assays despite the fact that endosymbionts may alter aphid-parasitoid interactions, as they can confer protection against parasitoids.

Evaluation of three molecular markers for identification of European primary parasitoids of cereal aphids and their hyperparasitoids.

Aphids are major pests of cereal crops and a suite of hymenopteran primary parasitoids play an important role in regulating their populations. However, hyperparasitoids may disrupt the biocontrol services provided by primary parasitoids. As such, understanding cereal aphid-primary parasitoid-hyperparasitoid interactions is vital for a reliable parasitoid-based control of cereal aphids.

Re-visiting the Aphidius urticae s. str. group: re-description of Aphidius rubi Starý and A. silvaticus Starý (Hymenoptera: Braconidae: Aphidiinae).

Here we tested Aphidius urticae s. str. host-associated lineages from Microlophium carnosum (Buckton), Amphorophora rubi (Kaltenbach), Macrosiphum funestum (Macchiati) and Aulacorthum vaccinii Hille Ris Lambers with the barcoding region of the mitochondrial cytochrome oxidase subunit I gene used to analyse population differences and elucidate phylogenetic relationships between the separated taxa.

The Effects of Aphid Traits on Parasitoid Host Use and Specialist Advantage.

Specialization is a central concept in ecology and one of the fundamental properties of parasitoids. Highly specialized parasitoids tend to be more efficient in host-use compared to generalized parasitoids, presumably owing to the trade-off between host range and host-use efficiency. However, it remains unknown how parasitoid host specificity and host-use depends on host traits related to susceptibility to parasitoid attack.

Genetic and morphological variation in sexual and asexual parasitoids of the genus Lysiphlebus - an apparent link between wing shape and reproductive mode.

Background: Morphological divergence often increases with phylogenetic distance, thus making morphology taxonomically informative. However, transitions to asexual reproduction may complicate this relationship because asexual lineages capture and freeze parts of the phenotypic variation of the sexual populations from which they derive. Parasitoid wasps belonging to the genus Lysiphlebus Foerster (Hymenoptera: Braconidae: Aphidiinae) are composed of over 20 species that exploit over a hundred species of aphid hosts, including many important agricultural pests.
