In 1973–2011 in Poznań, aphid catches were carried out using Johnson’s suction trap. Since then the suction trap located at the Institute of Plant Protection – National Research Institute in Poznań has continuously recorded the daily and seasonal dynamics of aphid flights. The collected results has been used to establish one of the largest databases of this type in Europe. The data also allow tracking...
Bird cherry-oat aphid (Rhopalosiphum padi L.) is the most abundant aphid species on cereals in Poland. It represents approximately 80% of all cereal aphids. Its anholocyclic forms are the most important vectors of Barley yellow dwarf virus (BYDV). These forms are new among the Polish population of R. padi. Their changes in development are the result of higher temperatures. High spring and summer temperatures...
Research was carried out to determine the extent of anholocyclic forms of bird cherry-oat aphid, Rhopalosiphum padi on winter barley, and to estimate the level of infection of winter barley crops with Barley yellow dwarf (BYD) viruses. Observations were made in 12 Polish regions. Each region is made up of four distinct locations, with different temperatures. The 12 observed regions were: Lubuskie,...
