The black bean aphid, Aphis fabae </em>Scopoli (Hemiptera: Aphididae), is one of the most important pests of several cultivated crops throughout the world. The predatory bug Deraeocoris lutescens</em> (Schilling) (Hemiptera: Miridae) have privileged position in biological control of aphids such as the black bean aphid, A. fabae</em>. Recently, there has been a growing interest in research concerning the possible use of plant extracts as alternatives to synthetic insecticide. In the present study, the effect integration of natural enemy with commercial pesticides (pirimicarb and abamectin) and plant extracts Melia azedarach</em> and Peganum harmala</em>, to control of A. fabae</em> were investigated. The result showed, combination of plant extracts M. azedarach</em> and P. harmala</em> with natural enemy causes significant decrease in this pest population and M. azedarach</em> has less hazardous on natural enemies. Also, the effects of commercial pesticides and plant extracts on the prey consumption of natural enemies were evaluated. Totally, the results of these experiments indicated that the ethanolic extract of M. azedarach </em>and pirimicarb have a minimum impact on the mortality of natural enemies, and the ethanolic extract of M. azedarach </em>has a minimum impact on the feeding of natural enemies.
