Seasonal dynamics of arthropod community diversity,evenness and relative stability in peach orchards

Abstract

Abstract: This study showed that the diversity index of total arthropod community in peach orchards was significantly correlated to the diversity index of both phytophages (r=0.9480) and predators sub-communities (r=0.7855),and the two sub-communities were correlative (r=0.6741).It was also significantly correlated to the evenness index of total community (r=0.7870),but not correlated to the evenness index of both sub-communities.The diversity index (H') of total community was significantly correlated to the ratio of predators individuals (S_d) and phytophages individuals (S_z) (r=0.8112) and of species (S_s) and individuals (S_i) (r=0.9188),but not correlated to the ratio of predators (S_pl) and phytophages (S_zl).
