摘要: Forty-four parthenogenetic lineages of Myzus persicae s.l. (Sulzer) from tobacco crops and peach orchards located in various regions Greece were examined to determine their response the insecticide pymetrozine using leaf-dip bio-assays. The results show that aphid has not developed resistance, as all exhibited resistance factors bellow 6.0. In transmission experiments potato virus Y (PVY) a lineage tobacco-adapted subspecies M. nicotianae Blackman on plants, one foliar application with provided adequate protection for 7 days. Pymetrozine significantly reduced both acquisition inoculation compared untreated control reduction was comparable mineral oil application. These are discussed terms advantage incorporating compound pest management strategies against non-persistent viruses, especially such because high selection pressure neonicotinoids resulting potential developing populations.
