The present research aimed to study the greenhouse experiments were carried out in order to confirm the efficiency of Deraeocoris lutescens Schilling (Hemiptera: Miridae) for the biological control of Myzus persicae (Sulzer) on protected sugar beet plants at 25 °C temperature. The aphid feeds on hundreds of host plants in over 40 plant families. Three aluminum cages was designed and built for testing. In each cage was placed four pots of sugar beet and Cages was named (control, treatment 1 and 2). The predatory bug has been successfully fed, reproduced and established on sugar beet plants under greenhouse conditions with M. persicae as prey during the greenhouse experiment. During the greenhouse experiment, the mean number of the aphid individuals per plant was significantly higher in the control treatment than in the treatments with D. lutescens. The total number of the prey had decreased gradually till it reached zero in the 5th week. Also, the nymphs population increase has stopped in the last week. The present result indicated that the population of the aphid effects on the predator population, while the predatory bug able to reproduce on sugar beet plants in the absence of prey. Thus, biological control of aphids using natural enemies, seems to be a successfully control allowing the amount of insecticides to be reduced, is needed to create sustainable agriculture development. In this regard, not only to control the world market production but also, It is important to the quality of products.
