pisum Harris, 1776) and syrphids (Diptera: Syrphidae; aphid´s predators) and their spatio-temporal associations in pea (Pisum sativum L.) monocrops and pea/spring barley intercrops were assessed (2014 – 2016). The second part of the dissertation thesis was based on the comparisons of abundances of pea aphid (A. pisum) and their natural enemies found on field pea plants, grown either as a monoculture or intercropped with spring cereals in small plot trials vs. large plot trials (2013 - 2015). In the third part of the dissertation thesis (2015 – 2017) the abundances and the distributions of B. pisorum eggs and the seeds infested by the insect pest were assessed in four differently structured field pea crops.
