Závislost početnosti vybraných druhů mšic (Aphididae) na počasí
Marková, Zuzana
This study focuses on fluctuations of abundance of the following aphids acting as viral vectors of potato plants (Solanum tuberosum L.): Leaf-curling plum aphid (Brachycaudus helichrysi Kaltenbach, 1843), Black bean aphid (Aphis fabae Scopoli, 1769), Peach-potato aphid (Myzus persicae Sulzer, 1776), Bird cherry-oat aphid (Rhopalosiphum padi Linnaeus, 1758) and the Aphis genus. The abundance of the winged forms of these aphids was evaluated according to samples from suction trap in Lípa u Havlíčkova Brodu in Czech Republic collected during the period from 2004 to 2015. This bachelor's thesis examines the effect of four climatic factors (temperature, radiation, rainfall and relative air humidity) on selected aphids in the year with the highest abundance of the monitored period.
