Malva neglecta Wallr. and Descurainia sophia (L.) Webb ex Prantl, common weed species growing in the orchard at the same time that eggs of the green peach aphid (GPA), Myzus persicae (Sulzer), are hatching on peach trees and on prunings on the floor of the orchard, supported development and reproduction of hatching fundatrices (stem mothers) in March and April. Sticky traps hung from peach trees caught large numbers of aphids falling to the ground. Fundatrices of the GPA that fall onto weeds or develop there are the early progenitors of the population buildup on weeds, not the fundatrigeniae (progeny of stem mother) as believed earlier.
