Diversity and Distribution of Diurnal Predatory Insects of

Predatory insects are among the natural enemies that can significantly reduce Spodoptera frugiperda populations. This species has been reported to spread into Magelang Regency, Central Java. Therefore, this study aimed to study the diversity and spatial distribution of diurnal predatory insects associated with S. frugiperda in the region. The research was conducted from December 2023 to May 2024. Sampling sites were selected using a stratified method, while maize fields within each site were chosen purposively. Insects were collected using hand-picking and sweeping net methods. Environmental data were also collected. The diversity of predatory insects found was analyzed descriptively. The relationship between predator abundance and abiotic factors was analyzed using simple correlation and regression. The results showed that 15 species of predatory insects of S. frugiperda were found in Magelang Regency. The predatory insects found came from three orders: Coleoptera, Hymenoptera, and Dermaptera. The most abundant species found was Coccinella transversalis (Coleoptera: Coccinellidae). These predatory insects were found in almost every region in Magelang Regency with varying abundances. However, most predators were found in the western and southern regions. These results provide information on the presence of local predators that can be utilized in future S. frugiperda management programs sustainably.
