abstract
The present research was carried out to study the population fluctuation of mango hoppers at different phenological stages under various Dapoli locations during 2015-16 and 2016-17. During the year 2015-16, the overall mean hopper population at different phenological stages was in the range of 0.13 to 29.27 hoppers per panicle. The maximum (29.26) hopper population was recorded at flowering stage in PA (PHM orchard-Alphonso) and minimum (0.13) at the egg stage in HK (Horticulture Nursery-Kesar). During the year 2016-17, the overall mean hopper population at different phenological stages was in the range of 0.07 to 17.05 hoppers per panicle. The maximum (17.05) hopper population was recorded at flowering stage in Pa USA (Pangari Bock-Unsprayed Alphonso) and minimum (0.07) was observed at the egg stage in HK (Horticulture Nursery-Kesar).
