Abstract:
A field study on seasonal incidence of key insect-pests and natural enemies in rice Oryza sativa (L.) was undertaken at Raj Mohini Devi College of Agriculture and Research Station, Ambikapur (C.G.) during Kharif 2023. The result revealed that the gall midge, stem borer as DH, leaf folder, whorl maggot incidence were recorded from 1st fortnight of September, and the peak incidence of gall midge (6.59% SS) and stem borer (9.71% DH) observed during 1st fortnight of October, while leaf folder (8.92% LD) and whorl maggot (4.48% LD) were recorded in 2nd fortnight of September and 1st fortnight of September, respectively. The stem borer as white ear head, panicle mite incidence and gundhi bug population were observed from 2nd fortnight of October to 1st fortnight of November and the peak activity reach during the 2nd fortnight of October to stem borer (12.40% WE) and 1st fortnight of November to panicle mite (9.68% Head Damage) and gundhi bug (12.92/hill), respectively.
