Abstract:
[Objectives] To clarify the community characteristics and stability
of arthropods in maize fields adjacent to different crops. [Methods] The number of
arthropod species in maize fields was systematically sampled with traps and
visual observation in maize fields adjacent to three different crops; coffee
plantations, rice fields, plum orchards, and in a maize monoculture. [Results] A total of 294 species of arthropods were
collected, belonging to 4 classes, 12 orders and 87 families. Compared to the
monoculture, the richness, diversity and evenness of arthropods in maize fields
adjacent to different crops was higher, but dominance was lower. Different
adjacent crops could be ranked with respect to the richness, diversity and
evenness of arthropods in maize fields as follows: coffee > rice > plum
> maize monoculture. The ranking of different adjacent crops on the Nn/Np, Nd/Np, Sn/Sp and Sd/Sp values of maize fields was the same, however, their ranking with
respect to the stability index (ds/dm value) of maize fields
was: coffee < rice < plum < maize monoculture. Maize fields adjacent
to coffee plantations had the most stable arthropod communities and maize
monocultures the least stable. [Conclusion] Planting maize adjacent to different crops can increase the
stability of arthropod communities in maize fields; maize fields adjacent to
coffee plantations have the most stable arthropod community structure.
