This might sound ridiculous – how can the tiny mosquitoes threaten wildlife? But – that is happening in the Galapagos Islands. The Southern house mosquitoes identified as the Culex Quinquefasciatus come by tourist planes and boats and bring with them the West Nile fever and the avian malaria – these are playing havoc on the local wildlife. The Galapagos giant tortoise and the marine iguana are among the threatened species apart from endemic birds including the waved albatross, the red-footed booby and flightless cormorant. In view of increase in tourism in the area, regular flights bring hordes of the tourists as well as supporting services. In 2007, the number of flights was more than 2000 and hundreds of arrivals by ship. The mosquitoes enter via these routes and need to be controlled by regular fumigation.
