Dynamika liczebności mszycy grochowej (Acyrthosiphon pisum Harris, 1776) na wybranych odmianach grochu i bobiku

Abstract

Summary The aim of the study was to assess the dynamics of number of the pea aphid on selected varieties of pea and faba bean. The experiment was conducted in a climate chamber in the Institute of Plant Protection – National Research Institute in Poznan, under controlled conditions (constant temperature, humidity and photoperiod), with ten replications. Five varieties of peas: Muza, Milwa, Model, Mentor, Mecenas, and two varieties of faba bean: Nadwiślanski and Amulet were tested. Observations of the number of aphids on each plant were conducted at regular intervals. The average fertility of aphids was defined for each variety. The results of the experiment showed that the pea plants were more inhabited by the pea aphid than faba bean varieties. Among the tested pea varieties, Acyrthosiphon pisum developed the best on the varieties Mecenas and Milwa, characterized by the highest protein level. As far as faba bean varieties are considered, low-tannin variety Amulet was a better host plant for the pea aphid.
