ResearchBP Microscope 2

The District participates in research projects as needed. Such research is frequently a collaborative effort with scientists at the University of Florida’s Florida Medical Entomology Laboratory (FMEL) in Vero Beach. Other collaborations have included the U.S. Fish and Wildlife Service, Florida Department of Environmental Protection, Harbor Branch Oceanographic Institution, Florida A&M University and other mosquito control organizations.  Mosquito control-related topics which have been investigated include: saltmarsh management (e.g., Rotational Impoundment Management), mosquito ecology, larvicide and adulticide effectiveness and mosquito-transmitted disease surveillance.  Much of this research has been published in peer-reviewed scientific journals.

IRMCD periodically tests the effectiveness of larvicide and adulticide compounds using a variety of methods developed by the World Health Organization, the Centers for Disease Control, and our own. These are performed in a variety of environments including laboratory, semi-field, and field tests.

Both new pesticides and others which have been used for years are periodically evaluated to make certain they remain effective in the environmental conditions and mosquitoes found in Indian River County.

 

Laboratory Testing

Because mosquitoes can become resistant to insecticides, our office periodically tests mosquito larvae and adults from our area to ensure that the materials that we use remain effective.

Semi-Field Testing

Semi-field testing is conducted outdoors, thus using natural sunlight and temperature while maintaining control over some variables such as flooding or drying.  This allows for experimental conditions which are more similar to field conditions than is experienced in a laboratory setting.

Field Testing

Operational evaluations are done to determine if laboratory and semi-field results can work in the field.

Other locations often have a somewhat different assortment of mosquito species and to deal with that we do.Thorough testing in the lab, in the blocks and in the field means IRMCD isn't wasting money on materials that just won't work for us. Products are expensive, so knowing exactly what works is important.

 

Environmental tests

No insecticide affects only one kind of organism. These photos shows part of a test inside an actual salt marsh to determine what impact our treatments might have on non-target aquatic insects. New and current products can also be tested in an exposed mini-environment.
