dc.description.abstractLong-term studies (2012–2018) of the formation of the Rhopalosiphum padi (L.) heteroecious population (number of remigrants, oviparae and eggs in autumn, number of perished eggs, fundatrices larvae, timing of flight of emigrants in spring) on the two samples of primary host Padus avium Mill. and P. avium x P. virginiana (L.) characterized by various morphophysiological features have been carried out. By the methods of mathematical statistics, it has been proved that this formation occurs under the significant influence of the year conditions (A), host plant characteristics (B) and these factors interaction (AB). The most visible was their highly significant impact on the number of wintering aphid eggs (A = 200.42; B = 142.6; AB = 25.612). Plant characteristics such as significantly larger leaf area from the middle part of the shoot on P. avium x P. virginiana, than on P. avium (t = 8.37; р0.01 = 2.85) was important for attracting remigrants and the prone buds on P. avium x P. virginiana - for oviposition and survival of eggs. Correlation between the period of leaf fall and number of aphid eggs on both bird-cherry samples is presented. The effect of weather conditions on R. padi and primary hosts relationships is discussed. Correlation (r = 0.76; p = 0.0048) between average temperature of October and eggs number on P. avium is given. R. fundatrices.eng
