The field experiment was conducted at Regional Horticultural Research Station, Navsari Agricultural University, Navsari (Gujarat) during 2009-2011. The result indicated that lowest hopper population (1.26 hoppers/twig or panicle) was observed in Totapuri followed by Dashehari and Ratna which were also considered less susceptible. The remaining entries were considered moderately susceptible wherein highest hoppers (9.28) were recorded in Mallika followed by Sonpoari and Alphonso. However, highest population of thrips (17.00/ twig or panicle) was recorded in Alphonso followed by Kesar. They were considered as highly susceptible entries. The remaining entries were found moderately susceptible indicating lowest thrips (5.43) in Totapuri. Moreover, all the mango genotypes suffered heavily from mango leaf gall midge damage and were considered highly susceptible entries, however lowest damage (12.40%) was observed in Totapuri, while it was highest (53.78%) in Mallika. Whereas, most of the mango genotypes were found less susceptible to leaf webber oriented damage wherein highest webbing (8.33/tree in pooled result) was found in Alphonso which was considered as moderately susceptible entry followed by Rajapuri and Kesar which also found place in the same basket. The lowest webbing (1.50 in pooled result) was observed in Neelam which was considered as less susceptible entry. Fruit fly damage was highest (28.07% in pooled results) in Alphonso followed by Kesar and were considered as highly susceptible entries. The remaining entries were found moderately susceptible to the pest indicating lowest damage (5.74% in pooled results) in Totapuri.
