The black bean aphid, Aphis fabae Scopoli (Hemiptera: Aphididae), is one of the most important pests of several cultivated crops throughout the world. The predatory bug Deraeocoris lutescens (Schilling) (Hemiptera: Miridae) have privileged position in biological control of aphids such as the black bean aphid, A. fabae. The other method to control aphids is the usage of insecticides and plant-derived chemicals. Integrated Pest Management (IPM) is an ecosystem approach to crop production and protection that combines different management strategies and practices to grow healthy crops while minimizing the use of pesticides. Recently, there has been a growing interest in research concerning the possible use of plant extracts as alternatives to synthetic insecticide. In this study, the integration of D. lutescens (N1 and N5 instar) with plant extracts of Peganum harmala L. and Melia azedarach L. and two conventional insecticides (pirimicarb and abamectin) is surveyed to manage A. fabae (1-2 and 5-6 days old), and also study the impacts on the predatory bug. Among different treatments, integration of N5 instar of the predatory bug with P. harmala has the highest aphid (1-2 days old) mortality rate (%95.33±0.60), and integration of N5 instar as the natural enemy with pirimicarb has the highest effect to manage 5-6 days old aphids (%94.00±0.71).
