Resistance of Triticum species to cereal aphids
The resistance of Triticum ssp. to English grain aphid (Sitobion avenae F.) and bird cherry-oat aphid (Rhopalosiphum padi L.) has been studied in different regions of Russia and the former Soviet Union. The dependence of resistance to aphids on the wheat

The spatial and temporal distribution of the grain aphid Sitobion avenae in winter wheat
The spatial and temporal distribution of the grain aphid Sitobion avenae F. (Homoptera: Aphididae) was studied within a field of winter wheat during the summer of 1996. Sampling was done using four nested grids comprising 133 locations.

Protein elicitor PeaT1 enhanced resistance against aphid (Sitobion avenae) in wheat
peer reviewedBACKGROUND Sitobion avenae, a dominant aphid in wheat that causes huge annual losses in agriculture, is mainly controlled using chemical pesticides. In this study, we investigated a protein elicitor, PeaT, for its induction of the defense

Cereal aphids (Sitobion avenae F., Rhopalosiphum padi L.) and Fusarium graminearum, the causal agent of Fusarium head blight (FHB), are major biotic threats to wheat that interact via their shared host. Co-localised S.

The complete mitochondrial genome of Indomegoura indica (Hemiptera: Aphididae)
In this study, the complete mitochondrial genome sequence of Indomegoura indica(Hemiptera: Aphididae) was determined. The circular genome was 15220 bp in length and contained 13 protein-coding genes (PCGs), 22 transfer RNA genes (tRNAs), 2 ribosomal RNA ...

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.

Predation of the cereal aphid Sitobion avenae by polyphagous predators on the ground
Abstract. 1. Polyphagous predator densities were manipulated in a wheat crop using polythene exclusion barriers. 2. The rates at which aphids fell to the ground and subsequently climbed and returned to the crop canopy were measured. 3. Peak aphid density was

Epidemiology and simulation of population development of Sitobion avenae in winter wheat
The epidemiology ofSitobion avenae and its natural enemies in winter wheat was studied in 1975, 1976 and 1977. Immigration was important until the end of flowering. The alate immigrants had apterous offspring. These became the driving force in population growth. Their offspring were mostly alatae which usually left the field.
