The field experiment was conducted to study the evaluation of selected insecticides for managing sapota fruit borer, P. erythrolophia during November 2013-14 on Kalipatti variety at New Orchard, College of Agriculture, Dharwad during January 2013-14 on thirty six sapota trees chosen for the study. Randomized Block Design (RBD) was used for the experiment with three replications and twelve treatments. The mean Percent fruit damage in different treatments ranged from 13.70 to 34.65 Percent. Spinosad45 SC proved very effective in recording lowest fruit damage of 13.70 Percent followed by Profenophos 50 EC (14.23%), DDVP 76 EC (16.78%), rynaxypyr 20 SC (18.77) and indoxacarb 14.5 SC (18.78) whereas, the remaining treatments were less effective. However, highest fruit damage was noticed in untreated check (34.65%). Highest reduction in fruit damage over untreated check was recorded by spinosad 45 SC (60.46%), followed by profenophos 50 EC (58.93), DDVP 76 EC (51.57). Emamectin benzoate 5 SG prove to be less effective as it registered lowest reduction in fruit damage (29.40%). However by navoluron 10 EC (33.53%) and NSKE 5% (34.57%). respectively on kalipatti variety. The overall mean larval population/twig was lowest in spinosad 45 SC (4.50) followed by profenophos 50 EC (5.75), DDVP 76 EC (5.90), indoxacarb 14.5 SC (6.31), rynaxypyr 20 SC (6.48) and flubendiamide 480 SC (6.49). The Percent reduction in larval population was maximum in spinosad 45 SC (60.00) over in untreated check; this was followed by profenophos 50 EC (48.88) and DDVP 76 EC (47.55). Emamectin benzoate 5 SG however proved to be less effective as it recorded lowest reduction in larval population (42.90). Spinosad 45 SC proved to be highly effective in recording highest fruit yield of 5327 kg/ha followed by Profenophos 50 EC (5298kg/ha) and Flubendiamide 480 SC (4991kg/ha). Thus spinosad 45 SC proved best candidate in recording lowest fruit damage, minimum larval population, highest sapota fruit yield, against sapota fruit borer, Phycita erythrolophia on Kalipatti.
