Population stability of natural enemies arthopods in organic mustard planting that planted in organic and mineral lands

This study aims to compare the identification results of various types of natural enemy arthropods found in organic mustard grown on organic and mineral lands; analyzing the natural enemy arthropod community in terms of diversity, evenness, species richness and dominance in organic mustard planting that planted in organic and mineral lands; to analyze the comparative of the population stability of natural enemy arthropods in mustard planting that planted in organic and mineral lands. The research used the exploration method, namely by observing the organic mustard planting in organic and mineral lands. Then identification of the captured arthropods and natural enemy arthopod communities and analyzed the population stability of natural enemy arthropods in organic mustard that planted in organic and mineral lands. The results of this study are 1). The types of natural enemies found in organic mustard plants planted on organic land are more than in organic mustard plants grown on mineral lands. On organic land found 20 species of natural enemies, both predators and parasitoids, while on the mineral field, 17 species of natural enemies. 2). Diversity , evenness and species richness of natural enemy species were higher in mustard planted on organic land compared to mustard grown on mineral lands, while the dominance index of natural enemies in organic land is lower than in mineral lands. 3). The population stability of natural enemy arthropods was more stable in organic than on mineral lands.
