All means followed by same letters at each column are not significantly different by Tukey’s multiple range tests, ANOVA (P < 0.05)
T₁: Hand picking + soil drenching with microbial pesticides, Lycomax, Russell IPM + trunk banding with packaging tape + spraying of spinosad; T₂ = Hand picking + soil drenching with microbial pesticides, Lycomax, Russell IPM + spraying of azadirachtin; T₃ = Hand picking + soil drenching with microbial pesticides, Lycomax, Russell IPM; T₄: spraying of chlorpyripos + cypermethrin
