Products Utilized For The Management Of Mosquito Populations
All products selected for use by VDCI are registered by both the U.S. Environmental Protection Agency (EPA) and the specific regulatory agency in the state where the product is used. These products are widely utilized in many mosquito abatement programs across the country because of their efficacy and minimal environmental impacts. VDCI carefully selects these products with the goal of protecting both people and the natural environment while economically reducing nuisance and disease-vector mosquitoes to tolerable levels.
What are the environmental impacts of larvicides?
VDCI’s most frequently used larval control products are Bti (Bacillus thuringiensis subspecies israelensis) and Bsph (Bacillus sphaericus), which are target specific biological products toxic to mosquito and black fly larvae. The bacteria contained in Bti and Bsph occur naturally in the soil and both of these soil bacteria can be digested by mammals, birds, reptiles, amphibians, and nearly all aquatic invertebrates without causing harm. The primary benefit of using these products is the reduction of mosquito larvae at a reasonable cost without negatively impacting the natural environment.
How does Bti work?
The Bti bacterium produces a protein crystal which is toxic only to mosquito, black fly, and certain midge larvae. VDCI uses liquid, granular, and briquet formulations of these products. The crystals are carried on corn cob granules and separate from the corn cob when the product hits the water surface. Because the larvae must ingest the bacteria, the granular and liquid formulations must be applied where water is present. The crystals are dissolved and converted into toxic proteins in the alkaline environment of the mosquito’s gut. These toxic proteins destroy the larval intestinal lining and ultimately cause the larvae to die within 24-48 hours after ingestion.
The primary active ingredient in VDCI’s most frequently used adulticide is permethrin. Permethrin is an insecticide in the pyrethroid chemical family. Pyrethroids (also known as synthetic pyrethroids) are man-made insecticides chemically similar to the pyrethrins found in natural pyrethrum. Natural pyrethrins are extracted from the flowers of the chrysanthemum plant, which have long been recognized for their insecticidal activity. Pyrethroids do not have the extent of adverse effects on non-target organisms that some other insecticide groups have. Pyrethroids are widely used in public health applications because of their relative safety for humans and other terrestrial vertebrates, high insecticidal potency at low dosages, and rapid knock-down effects.
