VectoLex WDG, Bacillus sphaericus (Valent BioSciences Corporation), was evaluated in 3 Florida Mosquito Control Districts under operational conditions. Application rates were 0.5 and 1.0 lb/acre and an untreated control in each district. Study sites included woodland ponds, residential areas such as catch basins, and commercial business retention ponds. Pretreatment and posttreatment assessments were made with a standard dipper at designated dipping stations. The most prevalent mosquitoes included Culex quinquefasciatus, Culex nigripalpus, Culex erraticus, Ochlerotatus infirmatus, Anopheles crucians, Anopheles quadrimaculatus, and Psorophora spp. VectoLex WDG was effective for 24-35 days posttreatment with one application.

Wide-Area Larviciding with a Buffalo Turbine® Mist Sprayer and Vectolex® WDG.

Wide-Area Larviciding techniques (WALS™) using aqueous suspensions of Bacillus thuringiensis israelensis and various types of mist sprayers have typically been employed against container-inhabiting species of mosquitoes such as Aedes albopictus and Ae. aegypti in urban peridomestic environments. However, relatively little work has been done to examine the use of WALS-applied aqueous suspensions of Lysinibacillus sphaericus (Ls) against susceptible species of mosquitoes in larger natural habitats such as forest pools, floodwaters, and marshes.

The control of medically important container-inhabiting mosquitoes is an ongoing challenge for mosquito control operations. Truck-mounted application equipment is a common option for rapid areawide larvicide deployment utilized by mosquito control operations. We tested the effectiveness of two truck-mounted sprayers (A1 Super Duty + Buffalo Turbine CSM3), for the deployment of water-dispersible biopesticides (VectoBac WDG:VectoLex WDG 50:50).

Biorational mosquito larvicides based on microbial organisms and insect growth regulators (IGRs) have played a vital role in integrated mosquito control, particularly since the invasion of West Nile virus to the United States in 1999. Products that are formulated with technical powder of the bacterium, Bacillus sphaericus Neide (recently Lysinibacillus sphaericus Meyer and Neide), are among the ones that have been extensively applied to combat Culex and other mosquito species. Due to the simplicity of the binary toxins, resistance to this pesticide in laboratory and field populations of Culex pipiens L.

This study aims at an integrated vector management (IVM) concept of implementing biological control agents against vector mosquito larvae as a cost-effective and scalable control strategy. In the first step, the mosquito species composition fauna of southern Benin was studied using standard entomological procedures in natural and man-made habitats. Altogether, 24 species belonging to 6 genera of mosquitoes Aedes, Anopheles, Culex, Mansonia, Uranotaenia, Ficalbia were recorded.

Effective Mansonia larval control is difficult to achieve in Polk County, Florida, because the larvae attach to the root and stem mass of water lettuce (Pistia stratiotes) and water hyacinth (Eichhornia crassipes). This study evaluated 2 Bacillus sphaericus larvicides as possible control products in 3 phosphate lakes in 2 areas maintained by Polk County Mosquito Control. VectoLex WDG was applied at 56 kg/km2 and 170 kg/km2 and VectoLex CG at 560 kg/km2 and 1,100 kg/km2.
