Abstract

The aim of this study is to assess the extent of attack and the potential for decreased production of maize types in the field caused to Spodoptera frugiperda. This study was carried out on a large scale, with four treatments and six replications (10 systematic sample replications). Parameters observed include population development, attack rate, the potential for production decline. The results show that this pest attack began to be found in maize 2 weeks after planting (wap) with an average population of 5.37 individu on sweet corn and 6.53 individu on glutinous corn. Furthermore, the population continued to increase up to 5 wap and lowering again to 8 wap. The regression analysis revealed a positive relationship between the larval population and the S. frugiperda attack rate. Sweet corn production decreased by 28.08 percent and glutinous corn output decreased by 25.04 percent, respectively. Overall, our results showed that S. frugiperda attacks continued to increase in both maize varieties (glutinous and sweet), which was indicated by an increase in population and a decrease in production on a field trial scale.
