Abstract: The impact of vector-borne disease is felt across the world. Negative impacts of the spread of these types of diseases can be seen in areas where large human populations overlap with the presence of mosquito populations. As populations have grown and large precipitation events become more common, the need for water management has led to an increase in the number of catch basins being used to provide this necessary service. The presence of these basins provides a great environment for the establishment of breeding sites for mosquito populations in the field. Mosquito control professionals rely on larvicidal applications to treat catch basins that are producing mosquito populations. Catch basin applications of larvicides have displayed mixed results due to the complexity of biotic and abiotic factors associated with each individual environment. In response to the need for catch basin mosquito control, MGK has developed a larvicidal product for treating problematic catch basins. Sumilarv 0.5G WSP, a product containing the insect growth regulator pyriproxyfen was developed specifically for deployment in catch basins. One of the main issues facing most larvicides is decreased efficacy of the product following major precipitation events or the introduction of organic matter into catch basins. Sumilarv WSPs have shown the ability to inhibit mosquito emergence from catch basins for up to 180 days after treatment. The extended efficacy of the product can be attributed to the nature of the active ingredient and the uniqueness of the formulation associated with the product. The overall efficacy of the Sumilarv WSPs paired with the single use method of application makes this product an extremely efficacious and cost-effective control option that can be deployed to control mosquito populations in catch basins.
