| Abstract: | Spodoptera frugiperda (J. E. Smith) is a migratory agricultural pest that happened in China in 2019 migrated from Myanmar. It has the characteristics of wide feeding range and strong migration, adaptability and reproductive ability. Breeding of resistant varieties is an important agricultural control measure, evaluating the damage grades of different maize varieties has a guiding effect on the subsequent use of multi-omics analysis to screen out specific resistance genes and cultivate resistant varieties. In this paper, waxy corn ‘Sunuo No.6’, dent corn ‘Xianyu 335’, sweet corn ‘Huangguan’, and 2 semident corns ‘LP259’ and ‘Zhengdan 958’ were selected to evaluate the damage grades of S. frugiperda under indoor conditions, and establish a population life table of the S. frugiperda. The damage grade of newly hatched S. frugiperda larvae to the five maize varieties ranged from high to low was ‘Huangguan’ (3.55±0.41) > ‘LP259’ (2.88±0.29) > ‘Xianyu 335’ (2.39±0.25) > ‘Zhengdan 958’ (2.15±0.25) > ‘Sunuo No.6’ (1.79±0.19). The adult preoviposition period of ‘Huangguan’ was the longest, which was (2.90±0.55) d. Larval duration was significantly different (P<0.05), the larval duration of ‘Xianyu 335’ was the shortest, which was (12.45±0.13) d. The weight of pupa of ‘LP259’ was the heaviest, which was (169.83±3.20) mg, both female and male adult fed on ‘LP259’ had the longest longevity, which was (10.36±0.58) d and (8.52±0.47) d, respectively. The survival rate of larval duration was not significantly different. The pupation rate and ratio of female of ‘Sunuo No.6’ were the highest, which was (83.10±3.29)% and (64.66±0.25)%, respectively. The eclosion rate of ‘LP259’, which was (95.24±1.99)%. According to the life table, the mean generation time of ‘Xianyu 335’ was the longest, which was (28.21±0.58) d. The net reproductive rate, intrinsic rate of increase and finite rate of increase of ‘Zhengdan 958’ were the lowest, which were 144.50±16.73, 0.1823±0.0023 and 1.1999±0.0028. The newly hatched S. frugiperda larvae prefered to feed on sweet corn ‘Huangguan’, and the comprehensive population life table to S. frugiperda in the population fitness of ‘Zhengdan 958’ was the lowest. It showed that ‘Zhengdan 958’ had the best tolerance to the S. frugiperda. The results of this study would provide a reference for the control of S. frugiperda and identification of potentially resistant species in Hainan. |
