By using pitfall and bait traps, an investigation was made on the diversity and similarity of ant communities in the areas infested and un-infested with Solenopsis invicta Buren in Shenzhen of Guangdong. The results showed that under the invasion of S. invicta, the ant species number in lawn and wasteland reduced obviously, with a decrease of 6 in lawn and 3 in wasteland, and the native dominant ant species in lichee orchard, especially in wasteland and lawn, were replaced by S. invicta. With the infestation of S. invicta, the diversity and evenness of ant communities in wasteland and lawn decreased but the predominance increased obviously, while it was in adverse in lichee orchard. The similarity coefficients of the ant communities between S. invicta infested and un-infested lichee orchard, wasteland and lawn were 0.6316, 0.5882 and 0.2941, respectively. |
