Abstract
FAW was an invasive pest and destructive as reported in Southern Rajasthan having high fecundity and have the ability of long distance travel which was most challenging. The survey on incidence and damage potential of S. frugiperda was carried out in maize growing area of Southern Rajasthan during July to October 2021 and 2022. Infested fields by S. frugiperda were found 100 per cent in both years. infestation by S. frugiperda was found 8 to 19.33 and 11 to 23 per cent with the mean 15.39 and 16.37 per cent or visual leaf damage rating (Davis scale 0-9) was 3 to 7 with the mean of 5.18 and 5.11, respectively in both years. The maximum infestation by S. frugiperda was recorded in Pratapgarh (17.94%) and lowest in Udaipur (12.65%) during 2021 and During 2022, the highest infestation by S. frugiperda was recorded in Pratapgarh (19.28%) followed lowest in Banswara (13.67%). The maximum visual leaf damage rating was observed in Rajsamand (6) and lowest in Udaipur (4.43) during 2021 and during 2022, maximum visual leaf damage rating was observed in Pratapgarh (6) and minimum in Rajsamand (4.25). On the basis experimental result infested prone area has been marked from southern rajasthan for applying control measure.
Keywords
Maize, Survey, Incidence, Per cent infestation, Davis Scale, FAW
Conclusion
Highest per cent infestation was recorded in Pratapgarh and lowest in Udaipur both 2021 and 2022, respectively so on basis of both year damage per cent is less than previous years due to establish their natural enemy and heavy rain or late sowing.
