  The Collier Mosquito Control District is always looking for alternative ways to treat mosquitoes. For several years now, the District has relied on only one adulticide for the aerial control of mosquitoes. However, it is important that the District have alternative insecticides to use for mosquito control as a replacement or substitute for the adulticide that is currently used. Therefore, as new products become available for use in Florida, the District reviews the literature on the product and then evaluates whether it might be beneficial to the District. If District personnel believe a new product could help the District with mosquito control, the Research Department tests the new adulticide under operational conditions.
The tests consist of various sample sites that are set up in an area where the District treats regularly. Each site contains two cages of wild-caught mosquitoes, to measure mortality, and a board with filter paper, to measure deposition. After the treatment, the caged mosquitoes are monitored for a period of 24 hours to record mortality. The level of mosquito control achieved with the test insecticide is compared to that obtained with the current insecticide.
The District has completed extensive testing of one potential alternative. Unfortunately, the product did not provide a satisfactory level of mosquito control, so this avenue of research will continue with other new products. |
