Defensive Symbiont Genotype Distributions Are Linked to Parasitoid Attack Networks. [PDF]
Facultative symbionts are widespread in arthropods and can provide important services such as protection from natural enemies. Yet what shapes defensive symbiont associations in nature remains unclear. We show that the symbiont Hamiltonella defensa's genotype distribution strongly aligns with sharing the same parasitoids, rather than host plants ...

Indirect effect of a transgenic wheat on aphids through enhanced powdery mildew resistance. [PDF]
In agricultural ecosystems, arthropod herbivores and fungal pathogens are likely to colonise the same plant and may therefore affect each other directly or indirectly.

Could behaviour and not physiological thermal tolerance determine winter survival of aphids in cereal fields? [PDF]
Traits of physiological thermotolerance are commonly measured in the laboratory as predictors of the field success of ectotherms at unfavourable temperatures (e.g. during harsh winters, heatwaves, or under conditions of predicted global warming).

Comparison of field population growths of three cereal aphid species on winter wheat
Population growths of three aphid species colonising winter wheat stands, Metopolophium dirhodum, Rhopalosiphum padi and Sitobion avenae, were analysed by regression method.

Proteomic profiling of cereal aphid saliva reveals both ubiquitous and adaptive secreted proteins. [PDF]
The secreted salivary proteins from two cereal aphid species, Sitobion avenae and Metopolophium dirhodum, were collected from artificial diets and analysed by tandem mass spectrometry. Protein identification was performed by searching MS data against the

Analysis of the genetic diversity in Metopolophium dirhodum (Walker) (Hemiptera, Aphididae) by RAPD markers [PDF]
The emergence of host-races within aphids may constitute an obstacle to pest management by means of plant resistance. There are examples of host-races within cereals aphids, but their occurrence in Rose Grain Aphid, Metopolophium dirhodum (Walker, 1849), has not been reported yet.

Comparison of the epidemiology of Metopolophium dirhodum and Sitobion avenae on winter wheat
The epidemiology ofMetopolophium dirhodum and its natural enemies on winter wheat was studied from 1975 to 1979 inclusive. AlateM. dirhodum colonize wheat from the middle of May onwards. Immigration occurs until mid-June. Population growth rates ofM. dirhodum can be as high as or occasionally even higher than those ofSitobion avenae. InM.

Predicting aphid abundance on winter wheat using suction trap catches
The relationship between the number of cereal aphids in flight (recorded by a national grid of suction traps in the Czech Republic) and their occurrence on winter wheat (in Prague) was established between 1999-2015.
