The light trapping technology was showcased for four major crops, namely, rice, corn, mango and vegetables at different municipalities of the four provinces of Region 1 [Ilocos Region, Philippines]. The technology uses the ultraviolet lamp that at specific wavelength greatly attracts various insect species. With lamps installed at farmers' fields, the number of insect pests, influence on the increase in yield and the degree of chemical reduction were noted to assess its efectiveness. Generally for rice, corn and vegetables, weekly insect pest collection by the light trap was highly extensive while population of the trapped natural enemy was very minimal. Crop yield increased from 5% to 50% and a reduction in chemical spraying from 25%-100% were noted for rice, corn and vegetable farms exposed to the light trap in comparison to farms without light traps. Mango exposed to light trap had considerable number of fruits per panicle causing a 50% increase in fruit yield. In addition, about 20-30% reduction in chemical spraying against insect pests was also observed. Excellent crop protection was augmented by weekly spraying of 0.1% calcium hypochlorite + a commercial hair shampoo which further reduced disease incidence resulting in clean and unblemished fruits. Net monetary benefit derived by partial budget analysis showed high economic returns in using the light trap. Cost efectiveness of the technology as an insect pest management tactic was highly demonstrated which warrants commercial availability of crops which are GAP (Good Agricultural Practices) - certifiable, i.e. with general safety to consumers.
