Characterisation of aphid antixenosis in aphid‐resistant ancestor wheat, Triticum monococcum

open access: yesPest Management Science, EarlyView.
A blend of 21 volatile organic compounds (VOCs) released from Sitobion avenae‐infested Triticum monococcum accessions MDR045 and MDR049 was identified and shown to induce antixenosis towards alate S. avenae. Abstract BACKGROUND Due to the increasing presence of insecticide resistance across cereal aphid populations, new aphid management strategies ...

Morphological separation of host adapted taxa within the Hyalopterus pruni complex (Hemiptera: Aphididae)

open access: yesEuropean Journal of Entomology, 2007
Morphometric variation of individuals in field collected samples of the Hyalopterus pruni complex from various Prunus species and regions of Greece was examined, to determine whether this variation is correlated with the host-trees from which the aphids ...

Response of Amblyseius swirskii to deltamethrin

open access: yesPest Management Science, EarlyView.
The analysis of toxicological and molecular data reveals target‐site as well as metabolic modifications associated with the resistance to deltamethrin in Amblyseius swirskii colonies. However, semi‐field assays show increased run‐off behavior after treatments with the same pesticide.

Feeding site location in birch aphids (Sternorrhyncha: Aphididae): The simplicity and reliability of cues

open access: yesEuropean Journal of Entomology, 2000
To establish the importance of different cues for feeding site location in aphids, two birch-feeding species were given access to leaves that were either orientated normally or inverted.

Metabolite‐based resistance in wheat varieties to aphid virus vectors: progress and future opportunities

open access: yesPest Management Science, EarlyView.
Sitobion avenae and Rhopalosiphum padi are major pests on wheat. Natural product‐based aphid resistance holds promise for the sustainable control of these pests. The current literature is discussed, highlighting knowledge gaps and challenges that need addressing. Abstract Cereal aphids, Sitobion avenae and Rhopalosiphum padi, cause severe yield loss in

The largest aphid mitochondrial genome found in invasive species Therioaphis tenera (Aizenberg, 1956)

open access: yesMitochondrial DNA. Part B. Resources, 2019
The complete mitochondrial genome of Therioaphis tenera (Aizenberg) was sequenced using Ion Torrent sequencing technology. The genome is 19,200 bp in length, which is the largest mitochondrial genome of aphids that has been sequenced so far.
