A 3-year study with 20-35 years old mango orchards of cv. Dashehari was conducted to study the
mango hoppers and their thermal requirement association. Hopper populations significantly varied
across seasons within a year. Lower populations (0.69-1.15 hoppers sweep-1) were recorded during
2011-12 as compared to higher populations of 1.32-4.03 hoppers sweep-1 during 2013-14. The highest
population was observed during 10-22 standard meteorological week in each season coinciding with
reproductive phase of mango. Thermal indices viz., growing degree days, heliothermal units and
photothermal units were applied to estimate the peak hopper population in Lucknow region. A total of
1000°Cd GDD, 9265.2 HTU and 15169.5 PTU were required to reach the peak hopper incidence with
significant linear relationships. These regression equations were explained up to 80-90% variations in
mango hopper populations. The association between mongo hoppers and thermal indices could be used
for prediction of peak incidence in Lucknow region for taking up timely management practices.
