Cowpea beetle (Callosobruchus maculatus) is one of the most important pests which damages quantity and quality of pulses including: beans, peas, vetches, lentils, etc. The effect of host variety was investigated on some biological characteristics of the pest including oviposition rate, adult emergence percent, adult weight and life duration. The experiment was conducted using a completely randomized design with five replications. Experiment was carried out at 30 ± 2 ˚C and 60 ± 5% R. H. under dark condition. The results showed that the maximum oviposition cowpea cultivar Parastou (140.8±3.7 eggs) and minimum on Pinto bean cultivar Khomein (50.34±3.65 eggs) despite the pest lay eggs on pinto bean cultivar Shad, pinto bean cultivar Khomein and red bean cultivar Goli no adults were emergence from the seed on these hosts. The most adult emergence occurred on cowpea and vetch. According to the results, the emerged adult female in cowpea (0.0426±1.22 g) and soybean (0.0154±0.24 g) has the highest and lowest weight, respectively. The maximum and minimum life duration of pest were observed on cowpea (24.2±0.2 day) and soybean (35.6±0.2 day), respectively.
