Video clips - mpeg format (Warning: these files are large)

• Mosquito larvae collection (14MB) - Stagnate pools of water can act as breeding sites for the species of mosquitoes that harbor West Nile Virus.  Many mosquito control districts monitor these areas as part of their control programs.  This video shows a good mosquito breeding habitat and a mosquito control officer dip testing for mosquito larvae.  The close up of the dipper reveals mosquito larvae and mosquito pupa.  
• Mosquito larvae under microscope (5MB) - This video shows a mosquito larva as it appears under a dissection microscope. In the end of the video clip, the head of the larva can be seen hanging down on the left and its dark breathing tube can be seen sticking up on the right. 
• Sideview of larvae under water (8MB) - In this video, two mosquito larvae can be seen hanging down from the surface of the water from their breathing tubes.  Mosquito pupae can be seen on the far right and far left sides of the screen.
