Abstract:
The present investigation was carried out in randomized block design (RBD) during Kharif 2019 at research farm, College of Agriculture, Gwalior (M.P.). The population of leafhoppers increased gradually from the 31st to the 38th SMW, reaching its peak during the 38th SMW. Afterward, the population declined and eventually disappeared after the 43rd SMW in both years. The occurrence of aphids was first observed during the 35th SMW for both years. The population of this pest began to increase and reached its peak during the 39th SMW. However, minimum population was recorded during the 44th SMW in both the years. Sting bugs were first observed during the 33rd SMW when the crops were 30 days old and reached its peak during the 38th SMW in both years. However, starting from the 39th SMW, the population began to decline and reached its lowest point during the 40th SMW and 41st SMW respectively during both Kharif 2021 and 2022, after which this pest disappeared. First appearance of spiders in field was recorded during 34th SMW and reached to its peak during 38th SMW during both Kharif 2021 and Kharif 2022. Afterwards population gradually decreases and reached to its minimum during 44th SMW in both successive years Ladybird beetle first appeared during 35th SMW and the population of ladybird beetle and reached to its peaked during 39th SMW thereafter it started declining gradually. Minimum population recorded during 44th SMW in both Kharif 2021 and Kharif 2022.
