To understand the ecological impacts on natural enemies of the target pests and non-target arthropods at jujube fields, a systematic survey was made at the four different treatment of jujube fields located 2.5 km west of Taigu (112°8′E, 38°9′N, 780 m elevation), Shanxi Province in 2004. Trees were 10 years old and in full fruit production, with a height of 5 m and a shading-degree of 0.4～0.6°. In each of the four experimental sites, five trees were chosen according to the chessboard sampling method to monitor the population dynamics of the arthropods. The trees were monitored every 10 days from March 10th to September 30th. For each treatment was replicated three times. The non-target insect pests, natural enemies and neutral arthropods were distinguished, based on their trophic relationships, as well as taxonomy. Species abundance, species dominance and community diversity indices were used to analyze and compare the seasonal trends of different functional groups in the four experimental fields.The systematic survey showed that more species were observed at integrated pest management jujube field intercropped with herbage than conventional management jujube field intercropped with herbage. In later period of jujube development, more species were observed at conventional management jujube field intercropped with herbage than conventional management jujube field without herbage. Significantly fewer (p<0.05) dominant functional groups of basal species were at jujube field intercropped with herbage than that of conventional management jujube field without herbage. Significantly more (p<0.05) dominant functional groups of intermediate and top species were at jujube field intercropped with herbage than that of conventional management jujube field without herbage. In different developing stages of jujube trees, significantly higher (p<0.05) average abundance of basal and intermediate species were at conventional management jujube field intercropped with herbage than that of conventional management without herbage. The average abundance of top species in integrated pest management jujube field intercropped with herbage was twice as much as that of conventional management jujube field both with and without herbage. Significantly higher (p<0.05) average abundance of top species was at conventional management jujube field intercropped with herbage than that of conventional management jujube field without herbage. The ratio of insect pests to natural enemies were that conventional management jujube field without herbage was significantly bigger (p<0.05) than conventional management jujube field intercropped with herbage. Non-management jujube field with herbage was significantly bigger (p<0.05) than integrated pest management jujube field intercropped with herbage. Significantly bigger (p<0.05) diversity indices were from integrated pest management jujube field intercropped with herbage than from non-management jujube field with herbage. The latter diversity indices were significantly bigger (p<0.05) than that of conventional management jujube field intercropped with herbage. Diversity indices of conventional management jujube field without herbage were smallest (p<0.05) at the jujube fields of four different treatments. Biodiversity and seasonal dynamics of functional groups abundance indicated that the neutral arthropods and secondary pests played an important role in regulating food chain of insect pests and natural enemies.
