Eco-friendly Sunlight Activated Larvicides for Control of Mosquito Borne Diseases

Technology Overview

This company has developed a novel sunlight activated larvicides to destroy Aedes mosquito larvae. This plant-derived eco-friendly solution offers a new tool to combat mosquito-borne diseases like dengue and zika. When activated by sunlight, this technology generates free radicals that are highly lethal and effective to kill larvae before they become mosquitoes. It follows a multi-targeted killing mechanism, thus providing a sustainable solution of mosquito control without the emergence of resistance on continuous use. It is also harmless to other aquatic animals, as sunlight can only penetrate through the translucent organisms like mosquito larvae to activate the larvicide, making this a safer, more targeted and cheaper solution than existing ones available.

Technology Features & Specifications

  • The larvicide is activated by sunlight, but also active on less sunny or cloudy days
  • Sunlight generates free radicals that are highly lethal and effective to kill larvae
  • Applied in low concentrations of 5 - 10ppm
  • Little chance of resistance emerging with continuous use due to the multi-targeted killing mechanism of the larvicide
  • The larvicide is derived from the plant source and is environment friendly
  • Harmless to other aquatic animals as sunlight can only penetrate through the translucent organisms like mosquito larvae to activate the larvicide

Potential Applications

This technology can be included in mosquito vectrol control programme to address the challenge of increasing mosquito population in Singapore and other tropical countries. It is capable of massive reduction in number of Aedes mosquito, before they reach adult stage thus stop them spreading the diseases like malaria, dengue and zika. This larvicide can be applied directly to mosquito breeding sites. This will reduce the frequency of fogging to terminate adult mosquitoes. The pesticides used in the fogging kill mosquito predators along with mosquitoes, but being neurotoxins it could lead to adverse side effects on humans. 

Market Trends and Opportunities

Mosquito borne diseases, like malaria, dengue and zika, have become a severe public health issue with nearly 700 million people being infected each year resulting in greater than one million deaths globally. The annual economic cost of dengue illness in Asia is estimated at US$2 billion, excluding the costs of preventive and vector control efforts.

The global bio-insecticides market is projected US$3.7 billion by 2020 with more than 16% growth. Asia Pacific is the largest market for insecticides followed by North America and Europe, which is due to its large diversity of flora and fauna. This 'green' larvicide, derived from natural source, could be interesting to local pesticide manufacturers and distributers for commercialising into the global market.

Customer Benefits

  • Green and environmentally friendly
  • Kills almost 100% of Aedes larvae
  • It is lethal to mosquito larvae at a very low concentrations thus require very small dosages to be effective
  • It is projected to reduce 50% in man hours spent on mosquito fogging
  • It is harmless to non-translucent organisms, and thus safe for other aquatic animals to ingest
