Abstract

Myzus persicae Sulzer, 1776 (Hem.: Aphididae) the most important pests of vegetable cultivated in the world. Pesticides are used extensively to control this pest. Intensive use of chemical pesticides to control pests caused various side effects such as residues in the product, pests’ resistance and push a great risk for human health, nature and environment. This study was undertaken to provide an alternative to chemical pesticides. For this purpose, the extract of Allium sativum L. (Liliaceae) and Melia azedarach L. (Meliaceae) were prepared. Then formulation studies of these extracts were carried out with several inert ingredients. Obtained preparations were subjected to quality control tests in the laboratory. As a result of these tests, preparations which were found successfully were separated/chosen for effectiveness studies on M. persicae. According to the results of laboratory studies, the highest dose found to be effective and theirs two upper doses (10, 15, 20ml/L) were taken to examine effect on M. persicae at the greenhouse conditions. The trial was established as randomized block design and 5 times in greenhouse. Commercial product Neem Azal T/S was used as positive control. The results of the greenhouse trials revealed that the insecticidal effect of M. azederach and A. sativum plants extract were 90.33% and 79.50% respectively. Also, it was determined that the insecticidal effect of M. azederach plant extract and Neem Azal T/S were 94.38% and 92.81 respectively.
