Plant viruses, and aphids as their vectors, are limiting factors in sugar beet production. Viral plant diseases are currently impossible to treat, but knowing the flight patterns of aphids can help reduce the number of potential virus vectors. Monitoring of aphid flight activities in sugar beet fields was done using yellow water traps from April to...

Alfalfa (Medicago sativa L.) hosts several species of aphid, Acyrthosiphon pisum (Harris), Aphis craccivora Koch and Therioaphis trifolii (Monell). The preference of the aphids of alfalfa plants for dense assemblies or individual plants, as well as for healthy or infested plants, was investigated in the field as in the laboratory. Years of field re...

Three aphid (Hemiptera: Aphididae) species can cause damage on pear trees. These are: Dvsaphis pyri (B.d.F.), Dvsaphis reaumuri (Mordv.) and Melanophis pyraria (Pass.). They cause damage by feeding on the leaves, sucking the plant juices and causing deformation of the leaves and petioles. Ali three species are holocyclic, and their main host is the...

The water lily aphid is a cosmopolitan species that feeds on various plants. Its primary hosts are Prunus species from which they migrate to their secondary hosts-aquatic and semi-aquatic plants. So far, in Serbia, Rhopalosiphum nymphaeae is recorded to attack only three plant species as secondary hosts. In our study, conducted in September 2020, w...

Aphids and ants are relatively well faunistically studied in Serbia. However, there is a need to present the mutualistic associations between these two groups of insects, since there is not sufficient information on this topic for the territory under investigation. In total, 220 samples of plant-aphid-ant associations were included in this study. I...

The risks in agriculture due to climate change are highly specific because they largely depend on the agricultural system, latitude, topography, disposition, and other local conditions. As such, it is difficult to decide which mitigation and adaptation measures are the most suitable in a given country and which should be prioritized in planning and...

The parasitoid species Ephedrus plagiator (Nees, 1811) (Hymenoptera: Aphidiinae) is one of the most important biological agents against pest aphids. We investigated whether this species was in competition with some other aphidiine species for the same hosts. We thus examined its potential in biological programs to control aphids. We applied an unsu...

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...

Volatile interactions between unattacked plants can lead to changes in their volatile emissions. Exposure of potato plants to onion plant volatiles results in increased emission of 2 terpenoids, (E)-nerolidol and TMTT. We investigated whether this is detectable by the ladybird Coccinella septempunctata. The odor of onion-exposed potato was signific...

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...

Host specificity is a fundamental properties of parasitoids. Parasitoids with narrow host ranges (high specificity) tend to be more efficient in their resource-use compared to generalists. This pattern is documented in aphid parasitoids and can be explained by the trade-off hypothesis between host range breadth and host use efficiency. However, it...

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 flight activities in seed potato fields have been studied by the yellow water traps. It is a good method for monitoring aphids as vectors of viruses, but this study also showed it is a suitable method for insect-diversity research. During the four-year studies, over 11.500 specimens were collected and a total of 107 different taxa of aphids w...

Changes in plant volatile emission can be induced by exposure to volatiles from neighbouring insect-attacked plants. However, plants are also exposed to volatiles from unattacked neighbours, and the consequences of this have not been explored. We investigated whether volatile exchange between undamaged plants affects volatile emission and plant-ins...
