Composition and diversity of arthropod community in Chinese rose-growing field.
The composition and diversity of arthropod community in Chinese rose-growing field were investigated in Shanghai between September 2006 and July 2007. The results showed that the phytophages accounted for most part of all arthropods collected, and the relative richness was 63.38% in 2006 and 48.96% in 2007. The relative richnesses of the other guilds were relatively low. Among the phytophages, Frankliniella intonsa and Myzus persicae were dominant species. Orius strigicollis and Misumenops tricuspidatus were the most predominant predator species. Both species richness and diversity index varied with seasons.
