The Alamosa Mosquito Control District (AMCD) operates as a fully integrated pest management (IPM) program.  Though there is no universal definition for IPM, it is often defined as a system designed to employ acceptable economic, ecological and toxicological techniques to reduce the negative impact of pest species to an acceptable level.  The AMCD achieves an IPM through surveillance, larvicide control, adulticide control and public outreach. 

   Our IPM begins with an extensive and historical light trap network that serves as the heart of our IPM.  The light trap network involves strategically setting mosquito traps throughout the district.  The traps are programmed to collect mosquitoes on a 24/7 basis.  Each day, the collection baskets from each trap site are brought into our surveillance laboratory where the mosquitoes are counted, identified by species, and tested for West Nile virus.  This information cascades into many decision making processes such as:


  • Directing larvacide crews to specific treatment areas 

  • Determining threshhold values for adulticide treatment areas

  • Finding mosquito habitat

  • RAMP testing detects the presence of West Nile virus which directs additional treatment programs
