| 中文摘要: |
| 红火蚁 Solenopsis invictaBuren 是一种重要的入侵物种，它对农业生产的影响是其危害的表现之一。为了揭示红火蚁入侵及其与蚜虫互作对绿豆 Vigna radiata植株上访花昆虫的影响，本研究采用田间试验调查了红火蚁的入侵及其与蚜虫互作对绿豆植株上访花昆虫的影响。结果表明：当无蚜虫存在时，在红火蚁入侵区与对照区内，绿豆植株上的主要访花昆虫种类数差异不显著，在入侵区内，小黑蝇日观察数量降低了68.1%；当有蚜虫存在时，与对照区相比，绿豆植株的访花昆虫种类数显著降低了20.4%；小黑蝇日观察数量降低了60.2%，爪哇摇蚊的日观察量比对照区减少了61.5%。因此，研究结果明确了红火蚁与蚜虫互惠对绿豆植株上访花昆虫产生一定的影响。 |
| 英文摘要: |
| Solenopsis invicta Buren is an important invasive species with significant potential threat to agricultural production. To confirm the effect of S. invictaand its mutualism with aphids on crops in southern China. We evaluate the impact of this invasive species on insect flower-visiting on a self-pollinated plants Vigna radiata by field investigation. Experimental field studies showed the negative effects of mutualism betweenS. invictaand aphids on the species richness of flower-visiting insect ofV. radiate, while no significant difference was found when only S. invictapresent.And the species richness of flower-visiting insect in mutualism betweenS. invicta and aphids areas were obviously decreased by 20.4% than that in the control areasS. invicta and its mutualism with aphids significantly reduced the number ofRhysophora sp by 68.1% and 60.2% compared with the control. And the number of Chironomus javanus Kieffer in the interaction between fire ants and aphids areas significantly decreased by 61.5% than that in the control areas, but it were no significant difference in fire ant invaded areas. Therefore, our result indicated the negative effect of S. invicta and its mutualism with aphids on insect flower-visiting on Mungbean. |
