title: [Effects of herbicides on diversity indices of cotton field arthropod community].
abstract: This paper studied the differences of the diversity, abundance and evenness of arthropod community and sub-community in cotton field among treatments haloxyfor-k (A), paraquat (B) and contrast (CK). The results showed that in the diversity of phytophagous sub-community, tA-CK = 3.099 and tB-CK = 2.449 (t > t0.05 = 2.228), the difference being significant, and in the diversity of predatory sub-community, tA-B = 2.260 and tA-CK = 2.377 (t > t0.05 = 2.228), the difference being also significant. In the arthropod community and sub-community, no significant difference was found for A-CK, B-CK and A-B. The abundance of arthropod community tA- CK = 4.359, and that of phytophagous sub-community tA-CK = 2.963, the effect being all significant (t > t0.05 = 2.228). No significant difference was found in the evenness of arthropod community and sub-community for A-B, A-CK and B-CK. The biodiversity had the same change trend for treatments haloxyfor-R (A) paraquat (B) and contrast (CK).
