Texturized Insecticidal Coating for Mosquito Mortality
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ovitraps and similar surfaces for mosquito treatment have smooth surfaces that hinder the effective release and transfer of insecticides to mosquitoes, leading to suboptimal insect mortality rates.
Innovation Solution
A texturized surface is created using an insecticidal composition comprising fumed silica, Iso-butyl-methacrylate polymer, and acetone solvent, applied through spraying, painting, or etching, to enhance the adherence and retention of insecticides, thereby improving mosquito mortality rates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a smooth surface is used for ovitraps, then the surface is easy to manufacture and apply insecticide, but the insecticide release and transfer to mosquitoes is hindered, leading to lower insect mortality rates
Solution Approach 1:
The patent applies a texturizing agent to create a porous or rough surface texture on the ovitraps. This porous structure increases the surface area and provides more contact points for mosquitoes, thereby improving insecticide transfer and release while maintaining ease of manufacture through simple coating processes
Solution Approach 2:
The patent uses a composite formulation consisting of insecticide mixed with a texturizing agent. This composite material creates a textured coating that combines the insecticidal properties with surface texturing, achieving both improved insect mortality and manageable manufacturing processes
2Duration of action of stationary object
If a smooth surface is used, then the application process is simple, but the adherence and retention of insecticide is reduced, resulting in shorter-lasting insecticide release
Solution Approach 1:
The texturizing agent creates a porous surface structure that enhances insecticide adherence and retention. The porous network traps and holds the insecticide, extending its release duration while the application process remains simple through conventional coating methods
Solution Approach 2:
The texturizing agent is incorporated into the coating formulation before application, pre-establishing the textured surface structure that will enhance insecticide retention. This preliminary texturing ensures prolonged insecticide release without complicating the application process

AI summary
Compositions, formulas, methods of making, mixing and applying insecticide formulations to different surfaces such as but not limited to interior surfaces of ovitraps, on walls and on chips and tiles to produce a texturized surface to allow for better transfer of the insecticidal active ingredients to insects, such as mosquitoes and the like, which land on or crawl on the surfaces, resulting in faster insect mortality rates. The texture of the insecticidal residue provides better transfer of the insecticidal active ingredients to insects that land on or crawl on the surface, resulting in faster insect mortality. The textured residue also enhances desirable surface characteristics for landing of mosquitoes and potentially other insects.
