China Article History Abstract As a severe invasive pest, red imported fire ant (Solenopsis invicta Edited by Buren) had important effects on ecosystem of its infected areas. Evandro Nascimento Silva, UEFS, Brazil Received 29 March 2016 Here, we surveyed the impact of S. invicta on populations of two Initial acceptance 07 August 2016 banana insect pests, banana skipper (Erionota torus Evans) and Final acceptance 12 September 2016 banana lacebug (Stephanitis typical Distant). The results showed that Publication date 25 October 2016 influences of S. invicta on the populations of E. torus and S. typical depend on weed coverage degree of banana plantations. Comparing Keywords S. invicta Solenopsis invicta, ecological effect, banana, to the areas without , banana skipper population was Erionota torus, Stephanitis typical. reduced by 39.2%, 41.4% and 23.4% respectively, in high, moderate and low weed coverage of banana plantations withS. invicta invasion. Corresponding author Banana lace bug population was reduced by 17.8%, 43.0% and 39.2% Yongyue LU respectively, in high, moderate and low weed coverage of banana South China Agricultural University plantations with S. invicta invasion. 526 College of Agriculture, 483 Wushan Road Tianhe District, Guangzhou, Guangdong China, 510642 E-Mail:
