Invasive Insects

Invasive species often pose the primary threat to biodiversity in the Pacific. USGS research focuses on the ecology, reducing impacts, and controlling highly invasive insect species. For example, USGS scientists are assessing novel mosquito control tools (e.g., bacterial endosymbiont Wolbachia). Mosquitoes carry diseases that affect people (e.g., West Nile virus, dengue); therefore, the...
