ABSTRACT: This work was conducted to study the biological impact of releasing the eleven-spotted ladybeetle, Coccinella undecimpunctata , Linnaeus (Coleoptera: Coccinellidae) in the control of the cotton whitefly,   Bemisia tabaci , Gennadius, the cotton aphid, Aphis gosspyii , Glover infesting common bean, Phaseolus vulgaris,  Linnaeus. Experiments were carried out during the period of 15 February, till 15 May 2014 at a private farm and a greenhouse located at El-Menoufia Governorate, Egypt.  Biweekly leaf samples were examined for the different stages of insects under study to determine the efficacy and the optimum time for releasing the predator. The obtained results indicated that the highest reduction percentages of preys (83.1%) at the level of 15 larvae/ plant under greenhouse conditions, were recorded four weeks after releasing. The grand mean reduction percentages of aphid and whitefly stages under greenhouse conditions along ten weeks of releasing were 38.24, 45.86, and 49.68 % for the treatments of 5, 10 and 15 newly hatched larvae/plant, respectively. Under open field conditions, the results revealed that the highest reduction percentages of preys were recorded at the eighth and tenth week after releasing.   The grand mean reduction percentages of aphid and whitefly stages under open field conditions along ten weeks of releasing were 38.0, 39.9, and 40.9 % for the treatments of 5, 10 and 15 freshly hatched larvae/plant, respectively.
