The infestation to know, the biology of maize aphid, Rhopalosiphum maidis (Fitch) in laboratory condition on maize crop was carried out at AICRP on biological control of crop pests, Anand Agricultural University, Anand during 2021-22. The aphid was found to be reproducing exclusively by viviparous parthenogenesis. Nymphs passes through four instars. Average periods of first, second, third and fourth instar were 1.20 ± 0.40, 1.36 ± 0.48, 1.40 ± 0.48 and 1.46 ± 0.49 days, respectively. The pre-reproduction, reproduction and post-reproduction periods of aphid on maize ranged from 3 to 7, 8 to 15 and 3 to 5 days with an average of 5.06 ± 1.15, 11.83 ± 1.71 and 4.03 ± 0.70 days, respectively. The longevity of adult was ranged from 14 to 26 days with an average of 22.36 ± 2.60 days with average fecundity was 32.63 ± 5.83 individuals per female on maize. Total life span of aphid ranged from 18 to 36 days with an average of 28.10 ± 3.40 days.
