Management Technique Against Spodoptera Exigua (Hübner) in the Different Elevation of Shallot

Abstract

Spodoptera exigua (Hübner) (beet armyworm) as the destructive insect pest in shallot. The purpose of the research is to determine difference of S. exigua management techniques based elevation in two different plantation. The research was conducted by collected primary data from shallot farmers in Anggeraja District (Mataran 650 m asl and Pekalobean 840 m asl) and Baraka District (Perarian 1.014 m asl and Parinding 638 m asl). The two places used in research is the center of shallot plantation in Enrekang Regency, South Sulawesi. The data was obtained by survey used 15 shallot farmers in each village. The results showed the control techniques different according to the elevation. S. exigua controlled by nylon nets only in areas < 700 m asl (Mataran 53% and Parinding 27%). In areas with elevation > 700 m asl (result of light trap in Mataran by 87% and Parinding by 80%). In the elevation > 700 m asl (result of light trap in Pekalobean about 100% and Perangian 0%). The mechanical control techniques by squeezing insect pest eggs at elevation of > 700 m asl (Pekalobean 93% and Perangian 6%), elevation of < 700 m asl (Mataran and Parinding both showed 60%). Conclusion of research, the control techniques different based on the elevation of shallot plantation.
