Insecticidal effect some plant extracts on Myzus persicae Sulzer (Hemiptera: Aphididae)

Abstract :

Green peach aphid, (Myzus persicae Sulzer)(Hemiptera: Aphididae), is a very important pest causing serious damage to vegetables, flowers and fruit crops. The efficacy of extracts from four plants namely Melia azedarach L. (Meliaceae), Veratrum album L. (Melanthiaceae), Rhododendron luteum Sweet (Ericaceae), and Helichrysum arenarium L. (Asteraceae) was tested in a search for alternative insecticides. Bioassays were conducted by two different methods to determine the effects of different concentrations. Experiments were performed using 30 mm diameter leaf discs from radish plants, Raphanus sativus L. (Brassicaceae). Each treatment and control were replicated ten times.As a result of the investigation, in the leaf dipping method, the extract of M. azederach, V. album, R. luteum and H. arenarium caused 94%, 67%, 65% and 61% nymph mortality respectively at 12% concentration. The mortalities of adults at the same concentrations were 91%, 85.71%, 57% and 61% respectively. For the spraying method, adult mortalities for M. azederach, V. album, H. arenariumand R. luteum were91%, 80.84%, 58% and 58% respectively at the same concentrations
