A study on population trend of N. lugens, S. furcifera and N. virescens was conducted at paddy field in Pekan Kandang, Melaka within August to October 2018. The aim of this study is to identify the population ecology of N. lugens, S. furcifera and N. virescens in paddy field with different time of sampling. Yellow sticky trap and yellow pan trap were used to trap the insect pests either in their nymph or adult stage, once a week. The traps were setting up randomly at 1m2 of area in 10 different plots of 20 acres of paddy field. The result shows the normal distribution of the population of insect pests at the paddy field.
