Monitoring for cereal aphids in winter wheat


, : Monitoring for cereal aphids in winter wheat. Netherlands Journal of Plant Pathology 87(1): 25-29

The authors describe a simple method that can be used by farmers to evaluate the level of infestation of winter wheat by aphids. An analysis of the results of studies in the Netherlands in recent years showed that Metopolophium dirhodum (Wlk.), Sitobion avenae (F.) and Rhopalosiphum padi (L.) can all cause a considerable loss of yield and that aphids on the stalk as well as on the ears should be taken into consideration.

The detection of copy number variants (CNVs) and the results of CNV-disease association studies rely on how CNVs are defined, and because array-based technologies can only infer CNVs, CNV-calling algorithms can produce vastly different findings.
