According to the research report “Larvicides Market by Control Method (Biocontrol Agents, Chemical Agents, Insect Growth Regulators), Target (Mosquitoes, Flies), End-use Sector (Public Health, Agricultural, Commercial, Residential, Livestock), and Region – Global Forecast to 2023″, is projected to reach $952.7 Million by 2023, at a CAGR of 4.86% during the forecast period.
The larvicides market in the public health sector is projected to grow at the highest CAGR of 5.15% from 2018 to 2023.
Mosquitoes and mosquito-transmitted diseases are among the principal public health concerns challenging governments globally, particularly in tropical and subtropical regions. The larvae of mosquitos are generally present on water bodies such as ponds, lakes, marshes, drains, and swamps, and hence, larvicides are used on these larval development sites to eliminate any chances of public health threats.
Environmental pollution, bio-amplification of food chain contamination, and harmful effects to beneficial insects are the prime demerits of chemical methods. In addition, there are numerous cases of resistance of species to insecticides, which encourages the use of biocontrol methods. Biocontrol agents such as Bacillus thuringiensis israelensis (Bti) and Bacillus sphaericus act as effective alternatives to broad spectrum larvicides in many situations, with no impact on the environment.

Chemical Agents with Banned Status
Organophosphates such as malathion, temephos, and chlorpyrifos are used for mosquito control. Malathion is available in the form of emulsions and dustable powders; it is generally used in large-scale public health activities in developing countries. However, chemical agents such as malathion and permethrin have been banned in the European region. Pyrethroids that are used for larval control include cypermethrin, permethrin, lambda-cyhalothrin, and deltamethrin which provide knockdown effects on insects with little residual activity. In the US, the use of cypermethrin, permethrin, and deltamethrin has been restricted, according to the EPA.
Temephos was considered harmful when used in large amounts. In December 2016, manufacturers were prohibited from selling or distributing their existing stock of products containing temephos. However, after December 2016, temephos-containing products have been approved for use, only if this use complies with US Environmental Protection Agency (EPA)-approved labels.
Microencapsulated Larvicide Products for Controlled/Slow Release of Active Ingredients
The major advantages of microencapsulation of pesticides are that they are convenient to use, suppress pests with precise control in the release of active ingredients, reduce the environmental impact of pesticides, and are less toxic to both, the environment and human health. Also, microencapsulated pesticides reduce labor costs by eliminating the need to monitor the crop for pests frequently to apply pesticides.
Temephos has been labeled for use in various habitats including tidal marshes, woodland pools, polluted water, trees, and as a pre-hatch treatment. It is less toxic, effective, and can be used to treat any of the larval growth stages. In the IPM program, temephos is recommended as a larvicide on a rotation basis, where it is used as a replacement for microbial or insect growth regulator (IGR) larvicides. The slow-release formulations of temephos provide control for more than 30 days.
