Abstract: 【Aim】 This study aims to investigate the effects of different soybean varieties on population parameters of the red and green color morphs of the pea aphid, Acyrthosiphon pisum, so as to provide an experimental basis for evaluation of resistance of soybean varieties to aphids and comprehensive control of pea aphids. 【Methods】 The adult lifespan, reproduction and population parameters of the red and green color morphs of the pea aphid on leaves of four soybean varieties (Fendoumulv 2, Nanxiadou 25, Nanheidou 20 and Nandou 5) in artificial climate chamber under the conditions of photoperiod 10L∶14D, temperature 23±1℃, relative humidity 60%±10% and illumination intensity 212 μmol/m2·s were observed and analyzed. 【Results】 The results showed that the adult longevities of the red and green color morphs of the pea aphid on Fendoumulv 2 were the shortest and the fecundities were the weakest as compared with those on other soybean varieties. The adult longevity of the red color morph of the pea aphid was 1.07 d longer than that of the green color morph, and the intrinsic rate of increase of the red color morph was 23.93 times as high as that of the green color morph. The adult longevity of the red color morph of the pea aphid on Nanxiadou 25 was 2.46 d longer than that of the green color morph, and the intrinsic rate of increase of the red color morph was 5.86 times as high as that of the green color morph. The adult longevity of the red color morph of the pea aphid on Nanheidou 20 was 2.47 d longer than that of the green color morph, and the intrinsic rate of increase of the red color morph was 1.54 times as high as that of the green color morph. The adult longevity of the red color morph of the pea aphid on Nandou 5 was 0.02 d shorter than that of the green color morph, and the intrinsic rate of increase of the red color morph was 1.41 times as high as that of the green color morph. 【Conclusion】 Different soybean varieties have different effects on the life table parameters of the red and green morphs of the pea aphid, and the two color morphs show different adaptive responses to different soybean varieties.
