Abstract:

In order to study the effect of repeated release of Neoseiulus(Amblyseius) cucumeris on the species composition and diversity of arthropod community in citrus ecosystems, we established bio-control orchards, natural orchards and chemical control orchards in the Mawei and Jin’an experimental field of Fuzhou, China. Our results indicated that the species richness of bio-control orchards was higher than that of natural or chemical control orchards at both sites. Diversity and evenness indices were higher in bio-control orchards than those of other orchards in the Mawei site, and those of chemical control orchards were the lowest. Among the variously managed orchards in Jin’an, evenness and diversity indices were highest in the natural orchards and lowest in chemical orchards. Our study suggests that citrus ecosystem arthropod diversity can be enhanced by releasingN. cucumeris to fight against the citrus pest mites while reducing the spraying of pesticide.

Key words: Neoseiulus(Amblyseius) cucumeris, citrus, biodiversity, arthropod community
