Project code: JKI-RS-08-2330
Contract period: 01.01.2008 - 31.08.2020
Purpose of research: Inventory & Assessment
Keywords: aphids, vectors, climatic changes, invasive species, risk assessment

The project aims at the detection of new species potentially endangering crop production and the establishment of a data base to get information on the influence of global climatic and environmental changes on the epidemiology of aphids. Thereby risk assessment for aphid pests and aphid transmitted plant viruses are facilitated providing the basis for the reduction of insecticide sprayings. Flight activity of aphids is monitored in a suction trap and a yellow water trap. Using stadardized traps enable the establishment of a EU-wide database. By determination of the trapped aphid species their flight activity is characterised and new species detected. Comparison of the flight activity and the natural occurrence of aphids in field plots allows a more accurate estimation of the resistance degree of wheat and barley genotypes.

Due to the suction trap at Aschersleben the largest data collection on flight activity of aphids in Germany has been created (since 1985). Most of these data have been transfered to the Euopean database (EXAMINE) (http://www.rothamsted.bbsrc.ac.uk/examine/) By this trap Diuraphis noxia, being a pest on wheat world wide, was detected for the first time in Germany.
