Hubungan antara struktur lanskap dan keanekaragaman Hymenoptera parasitoid: Sebuah model interaksi pada pertanaman kacang panjang
Keywords:biological control, composition, landscape, parasitoid, structure
Landscape structure and composition are an important part of a landscape’s character which can affect the presence of predators and parasitoids, and influence the effectiveness of biological control. This study aims to examine the relationship between landscape features and the diversity of Hymenoptera parasitoids using long bean plants as a model. Sampling was conducted in a 50 m x 25 m plots. In each plot, 4 transects, each 50 m in length, were used to sample insects. Insects were collected using yellow pan traps, malaise traps, and direct hand collections. Overall, a total of 4.792 individuals of Hymenoptera parasitoids were collected, which consisted of 28 families and 256 species. Results showed that landscape characteristics influence the diversity, abundance, and evenness index. Diversity index and evenness are higher in landscape that is dominated by agricultural class area. The abundance of Hymenoptera parasitoid was higher in the landscape that is characterized by tree class areas compared to the agricultural class area.
