  • Sweep sampling is the most common method used to the community structure research for grassland grasshopper, it is easy and cost-effective. To study the effects of sampling time on the community structure research for grassland grasshopper with sweep sampling, the collected data obtained from various times during 07:00-19:00 was compared in this study. The results showed that the caught numbers of adult and nymphal grasshoppers were not statistically different (P>0.05) from 07:00 to 17:00. There were no significant differences (P>0.05) in ratio of nymphs, community diversity, evenness and richness across times sampled. Regression analysis showed no correlation between grasshopper capture and temperature range from 18 to 28 ℃ (P>0.05). In conclusion, the suitable time for grasshopper community research with sweep sampling is from 17:00 to 07:00 clock.
