Experiments were carried out at Quesna, Menufyia governorate during season 2010 in summer plantation to evaluate the efficiency of conventional insecticide Sumithion (50 EC) or Fenitrothion and non-conventional insecticide against the main pests attacking kidney bean. Regarding to the conventional insecticide Sumithion exhibited a high efficiency against Aphis craccivora (koch.) population with the highest percentage of reduction (83.4%) after two days from treatment, while the non- conventional insecticide liquid sulfur 30% caused the highest percentage of reduction 77.1 and 83.1% after 5 and 7 days from treatment. With respect to the conventional insecticide Sumithion exhibited a high efficiency against Bemisia tabaci (Genn.) population with the highest percentage of reduction (93.7%) after two days from treatment, while the non- conventional insecticide Mineral oil and liquid sulfur 30% caused the highest percentage of reduction 85.0 and 84.5% after 5 and 7 days from treatment, respectively. Results showed that, the conventional insecticide Sumithion exhibited a high efficiency against Emposca discipiens Poali population with the highest percentage of reduction (82.1%) after two days from treatment, while the conventional insecticide Sumithion and non- conventional Orange oil caused the highest percentage of reduction 53.8 and 60.5% after 5 days and 7 days from treatment, respectively. In addition, the results revealed that, the conventional insecticide Sumithion exhibited a high efficiency against Liriomyza trifolii (Burgess) population with the highest percentage of reduction (75.5%) after two days from treatment, while the conventional insecticide Sumithion and non- conventional Liquid sulfur 30% caused the highest percentage of reduction 64.1 and 47.8% after 5 and 7 days from treatment, respectively. The obtained results indicated that, the non- conventional insecticide Mineral oil exhibited a high efficiency against Tetranychus urticae (Koch.) population with the highest percentage of reduction 87.2% after two days from treatment, while the non- conventional insecticide Liquid sulfur 30% caused the highest percentage of reduction 76.8 and 81.8% after 5 and 7 days from treatment, respectively. Regarding to the kidney bean crop parameters, the conventional insecticide Sumithion exhibited a high efficiency against the main pests on kidney bean, as a highest mean length of plants, the highest mean number of podes/ plant, the highest number of seeds/ pode and the highest mean weight of 100 seeds. On the other hand, the non-conventional pesticides Liquid Sulfur, Mineral oil, Orange oil and Bio-fly exhibited intermediate efficiency against the main pests on kidney bean with respect to the aforementioned parameters of the crop.
