Komunitas serangga herbivora penggerek polong legum dan parasitoinnya: studi kasus di daerah Palu dan Toro, Sulawesi Tengah

Abstract

The abundance and species richness of herbivore insects are not only determined by its host plants, instead it is also determined by its natural enemy complexes. Altitude and habitat types are two environmental factors that may also influence the herbivores as well as its parasitoids. To investigate the influence of these factors toward the abundance and diversity of pod borers, a research was conducted in Palu city (altitude until 90 m dpl) and Toro village, district Kulawi, regency Donggala, about 92 km from Palu (altitude above 700 m dpl). The aim of this research is to study the community structure of herbivore insects and its parasitoid communities. Insect communities studied are the pod borers of various legumes plants, its niche breadth, its herbivore load and parasitoid load of a diverse legum plant community. Pod borers diversity and parasitoid community of Crotalaria striata was studied at different altitude and habitat type.
