They fly before the leaves of bird cherry mature and at a time when numbers of insect predators are rapidly increasing. The bird cherry‐oat aphid Rhopalosiphum padi has a wide geographic distribution and correspondingly different life cycles. Lazzari SMN; Voegtlin DJ, 1993. Cereal volatiles were identified by GC-MS and olfactometer tests were performed with each compound. armer environmental conditions. L.) is the most abundant aphid species on cereals in Poland.

They alternate between the aerial plant parts of Prunus species through the fall and winter while colonizing other herbaceous hosts' roots for the remainder of the year. The species alternates between the primary winter host, bird cherry (Prunus padus) where sexual reproduction occurs and secondary summer Poaceaehosts. Rhopalosiphum padi (L.). Rhopalosiphum padi. Nymphs, 12-h-old, were placed individually in cylindrical plastic dishes (2.5 × 2.5 cm), with a layer of 1% agar in which leaf disks of signal grass had been placed. Bird cherry-oat aphid (Rhopalosiphum padi) is an aphid in the superfamily Aphidoidea in the order Hemiptera.It is a true bug and sucks sap from plants. These three species often have distinctive feeding sites. Holocyclic individuals of the aphid Rhopalosiphum padi reproduce by cyclical parthenogenesis, while anholocyclic individuals are obligate parthenogens. Protect.
