The study was conducted in the experimental area of Sher-e-Bangla Agricultural University (SAU), Sher-e-Bangla Nagar, Dhaka-1207, Bangladesh, during the period from July to October 2016 to find out the effect of different levels of NPK on insect pests in transplant aman rice. BRRI dhan33 was used as the test crop in this experiment. The experiment comprised of different NPK (Nitrogen, Phosphorus and Potassium) fertilizers doses as treatment where, T0= absolute control, no NPK fertilizers, T1= NPK@ 45, 50, 40 kg/ha, T2= NPK@ 70, 25, 40 kg/ha, T3= NPK@ 70, 50, 20 kg/ha, T4= NPK@ 70, 50, 40 kg/ha, T5= NPK@ 70, 50, 60 kg/ha, T6= NPK@ 70, 75, 40 kg/ha and T7= NPK@ 95, 50, 40 kg/ha. The experiment was laid out in a Randomized complete block design (RCBD) plot with three replications. Data were recorded on different types of insect pests that were identified for the entire growing period with their number and incidence on rice plants.
