Beet armyworm (Spodoptera exigua) poses a challenge for shallot production because it can exist in fields throughout the year. This study aims to observe the dynamic population during shallot off and on-seasons. Additionally, this study aims to determine the correlation between S. exigua moth captures and damage intensity. The research was conducte...

... average number of S. exigua captured during periods when fields were cultivating chili, rice, or non-cultivated was lower compared to the shallot periods. Specifically, the average number of S. exigua captured was 0.4 moth/trap/day during the chili period, 0.7 moth/trap/ day during the rice period, 0.8 moth/trap/day during first non-cultivated period, 2.4 moth/trap/day during the shallot period, and 2.1 moth/trap/day during the second non-cultivated period (Figure 1). The on and off-season observations lasted for seven months and totalled 26 off-season observations and 18 on-season observations. ...
