Abstract
Shallots are one of the horticultural crops that are widely cultivated in certain areas in South Sulawesi. One of the limiting factors in efforts to increase the production of shallots is the disturbance of plant pests and plant diseases. Spodoptera exigua is a major pest on shallot plants. This pest was found attacking shallot plants from the time the plants appeared on the ground until harvest. The yield loss of shallots can reach 70% to 100% in the dry season if it is not controlled using pesticides. This study aims to determine the percentage of damage to shallot plants due to Spodoptera exiqua attack by using light traps. This research was carried out on land owned by farmers from August to October 2020. In this study, paired T-test was used with two treatments, namely P0: shallot plantation plots without trap lights, P1: shallot plantation plots using light traps. Observation parameters were the percentage of leaf damage of shallots and production. The results showed that the average percentage of leaf damage of shallots with the use of trap lights was lower than without using trap lights. The production of wet bulbs of shallots in the lamp trap treatment was 7.29 tons/ha and higher than the treatment without lamp traps, which was 4.95 tons/ha.
