Species richness, dominance and diversity of arthropod community in the weed habitat surrounding a rice field

A systematical survey focusing on arthropod community living in the weed habitat around a single cropping rice field was carried out in Gutian county, Fujian province, from May to September 2001. The species richness, dominance, diversity and their fluctuations of the arthropod community were studied. Resource of natural enemies was rich in the weed habitat and it plays an important role in the survival and development of the natural enemies of rice insect pests. The species richness, dominance, diversity diminished in the prophase of rice growing and increased in the anaphase.
