Observation on inter-specific competition of two mosquitoes

  Objective   To observe, recor d and analyse the phenomenon of inter-specific competition of two dominant mosquitoes(Culex pipienspallens and Armigeres subbalbeatus)at Dawa forestry of meng mountain.And to find the competition characteristics of Armigeres subbalbeatus.

  Methods   The niche theory was applied to analyse the inter-specific competition characteristics of Armigeres subbalbeatus in the qualitative and quantitative niche.It included niche breadth, proportional similarity, niche overlap and nicheseparation.And two dimensional niches were comparatively analysed in time and temperature resource, too.

  Results   The two dominant mosquitoes had more proportional similarity, so the inter-specific competition was certainly.Armigeres subbalbeatus would win the competition, because ithad more niche br eadth and more niche overlap to Culex pipiens pallens.The two mosquitoes would temporarily co-exsist by the way of niche separation in time and temperature resource.

  Conclusion   To establish a mathematical model on the inter-specific competition char acteristics of the Armigeres subbalbeatus.About the competition result, the or etically analysis is consistent with the practice investigation.
