Flight activity of aphids as potential vectors of viral infection of alfalfa plants were monitored in Serbia for the first time in Europe. Research was conducted at the location Progar (Srem) for two years using six yellow water traps. A total of 1626 individual winged aphids were collected. The collected specimens were classified into 49 different...

Aphidius ericaphidis, an aphid parasitoid originally described from North America, is recorded in Europe for the first time, based on morphological and molecular analyses. The species is recorded in Serbia, the Netherlands, Sweden and the United Kingdom. It was formerly recorded as Aphidius sp./Ericaphis latifrons/Vaccinium uliginosum from the Alps...

The functional roles of different habitats may depend on the combined effect of local habitat management and the structure and composition of the surrounding landscape. However, this interaction is not well understood due to the common practice of pooling many different habitat types in one simple landscape metric (e.g., percentage crop area). In t...

Population dynamics and flight activity of alfalfa aphids were documented at two locations in Serbia in 2011 and 2012. Additionally, the abundance of coccinellid predators was tested for correlation with aphid abundance. In order to verify the potential presence of the invasive Acyrthosiphon kondoi, aphids were collected from 44 alfalfa fields. Two...

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 h...

Aphids (Hemiptera: Aphididae) are important pests of alfalfa all over the world. One of the most important ones is a blue alfalfa aphid - Acyrthosiphon kondoi Shinji. Morphology of the species is very similar to a green alfalfa aphid - Acyrthosipom pisum Harris. Saliva of A. kondoi is very toxic and this is why it is more important than other pest...

Fauna of aphidiine parasitic wasps has been intensively studied in the past 20 years in Serbia. Lysiphlebus testaceipes, a species introduced originally to France, has become broadly established in the Mediterranean area. Also, it has recently been categorized as an invasive species. It was found in the Niška kotlina valley and in a small gorge, th...

One hundred and eighty-six tritrophic parasitoid-aphid plant associations were established between Lysiphlebus fabarum and 64 aphids with 148 different plant species from the territory of Serbia. We identified 18 aphid genera of which the genus Aphis was represented by 38 species. The most frequent interactions between the parasitoid and the hosts...

Eight aphid species were determined as new records for Serbia as a result of the evaluation of the specimens caught by yellow water traps used for monitoring vector activities in seed potato crops during the 4 years 2007–2010. The invasive aphid species Macrosiphum albifrons Essig 1911; and the new species Acyrthosiphon cyparissiae (Koch 1855), Cte...

Lysiphlebus testaceipes (Cress.) is an aphidiine parasitoid originally introduced to Europe as a biological control agent of citrus aphids in the Mediterranean. It has rapidly become widespread in coastal areas continuing gradually to expand inland. L. testaceipes exploited a large number of aphids in Europe, including new hosts and significantly c...

Aphid parasitoid species (Hymenoptera: Braconidae: Aphidiinae) of central submountain parts of Iran were investigated. A total of 40 parasitoid species, reared from 80 aphid taxa occurring on more than 126 plant taxa in the studied area were recorded while 400 tritrophic parasitoid-aphid-plant associations were detected. These included 239 new reco...

We report the occurrence of Lysiphlebus orientalis in Serbia, an aphid parasitoid from the Far East that is new to Europe and has the potential to become invasive. Our finding based on morphological characters is confirmed by analyses of mitochondrial cytochrome oxidase subunit I sequences. An increase in number and an expansion of the host range w...

This study presents the results of a survey of aphid parasitoids of the subfamily Aphidiinae (Hymenoptera: Braconidae) in western Iran. Thirty nine species of aphid parasitoids belonging to nine genera were collected and identi- fi ed in association with 54 aphid species occurring on 77 host plants. In all, 129 parasitoid-aphid associations were...

Sampling of aphids and parasitoids was conducted in diverse cereal and vegetable crop habitats in Slovenia in the period from 2006 to 2010. Over 330 samples containing primary or secondary parasitoids or both were taken. In 25 different vegetable crops 15 species of aphids parasitized by 18 species of primary parasitoids were found, and were associ...

This study brings a list of original data of parasitic wasps from the subfamily Aphidiinae collected on the territory of Serbia and Montenegro associated with their aphid hosts and plants. Twenty-three genera and 122 species of Aphidiinae were identified from 204 aphid taxa occurring on 344 plant taxa. A total number of 794 parasitoid-aphid-plant a...

Two new species of aphid parasitoids from the Balkan Peninsula are described. Aphidius chaetosiphonis sp. n. was reared from Chaetosiphon sp./Potentilla clusiana, while Aphidius balcanicus sp. n. was reared from Acyrthosiphon malvae/Geranium spp. associations. The taxonomic position of both species has been discussed.

Multivariate morphometric analysis was used to compare nine characteristics of 47 populations of Myzus persicae (Sulzer) originating from two host-plants, peach and tobacco, from 13 localities in 2004 and 34 localities in 2005, in Serbia and Montenegro. Multivariant discriminant analysis showed there to be a distinct discrimination between the popu...

In two years of investigating resistance of the peach-potato aphid Myzus persicae (Sulzer) by molecular methods, several types of resistance were established in the majority of individuals from peach and tobacco in Serbia and Montenegro. Most of the tested individuals had the FE4 gene, which encodes production of FE4 esterase. The gene responsible...
