Abstract

Management of insect pests employs several tactics compatible with each other to become effective. Generally, insect pests are widely distributed and oftentimes their population is overlapping, hence management is difficult. Management strategies vary from one pest to another and also with different growth stages of the insect. Knowing the right time to apply intervention is necessary to better manage a particular pest. Several tools are being used to determine the population fluctuation of these pests. One is through light trapping. Light trap catches provide a significant clue to the diversity of nocturnal insects and how populations fluctuate. Determination of population fluctuations or incidence of insect pests in the field is useful not only to determine the activity of insect pests in relation to several weather factors but also to study the population dynamics of insects during the particular period. A light trap was installed at the PhilRice CES to obtain data on the population dynamics of the major insect pests, to aid in decision-making in insect pest management. The weekly light trap collections that started in January 2016 were brought in the laboratory for sorting, identification and counting. The population of the insect pests peaked in March and September during the dry and wet seasons of 2016, respectively.
