Abstract: Investigation on “Incidence and Management of Major Insect-Pests of Pearl Millet [Pennisetum glaucum (L.) R. Br.]â€. revealed that the infestation of shoot fly was recorded from 31st standard meteorological week (SMW) and remained throughout the crop season in both years and the peak of first and second years in 33rd and 34th SMW, respectively. The infestation of stem borer was noticed in the 32nd SMW during both the years and respective peak of 2014 and 2015 in 36th and 34th SMW.
The damage of white grub was observed in 31st SMW and peak was in 32nd SMW during both the years. The effect of abiotic factors on white grub damage exhibited significant negative correlation with maximum temperature, non-significant negative correlation with minimum temperature and sunshine hours with white grub damage during 2014. However, significant positive correlation existed with average relative humidity and non-significantly positive correlation with total rainfall. During 2015, the non-significant negative correlation was observed with maximum temperature, total rainfall and sunshine hours, however, non-significant positive correlation existed with average relative humidity and minimum temperature.
The two years survey during Kharif 2014 and 2015 on insect-pests of pearl millet in Semi-arid Eastern Plain of Rajasthan revealed that nine insect species, viz., shoot fly, stem borer, white grub, termite, grey weevil, leaf roller, chaffer beetle, grasshopper and Helicoverpa larvae appeared on pearl millet. White grub was observed as major pests, however, the incidence of other pests was meager.
