Mosquito Net Trapping Device for Insecticide Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Insecticide resistance in mosquitoes complicates the control of mosquito-borne diseases, as existing methods using insecticide combinations provide only temporary relief and can lead to rapid selection of resistant phenotypes, necessitating a more effective and long-term solution for malaria and other vector-borne disease management.
Innovation Solution
A mosquito trapping device comprising a lid, body, and funnel with mosquito netting that captures mosquitoes through a central opening, preventing them from infecting humans by trapping them in a collection bag, thereby reducing the spread of insecticide-resistant mosquitoes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If insecticide combinations are used to control mosquitoes, then mosquito mortality increases temporarily, but insecticide resistance develops rapidly leading to long-term control failure
Solution Approach 1:
The invention extracts mosquitoes from the environment using trapping devices and physical containment methods, separating the control mechanism from chemical insecticides. This physical extraction approach avoids the resistance development issue while maintaining control effectiveness.
Solution Approach 2:
The patent replaces chemical insecticide systems with mechanical trapping systems including funnels, nets, and collection containers. This mechanical substitution eliminates the selection pressure that drives resistance development while providing sustained mosquito control.
2Reliability
If insecticide combinations are deployed widely to manage resistance, then resistance selection is temporarily mitigated, but implementation costs and time requirements increase significantly
Solution Approach 1:
The invention segments the mosquito population control approach into individual trap units that can be deployed independently. This segmentation allows for rapid deployment without the complex coordination required for insecticide rotation strategies, reducing implementation time while maintaining resistance management effectiveness.
3Productivity
If multiple insecticide classes are used in combination, then mosquito mortality increases, but the complexity and cost of implementation increase
Solution Approach 1:
The invention extracts mosquitoes physically before they can develop resistance, eliminating the need for complex multi-insecticide protocols. The extraction-based trapping system achieves mosquito mortality through containment and removal rather than chemical exposure, simplifying the control protocol while maintaining productivity.

AI summary
The invention is a mosquito net trapping device (MTD) that can be installed on any type of mosquito net to transform it into a mosquito trapping net. The MTD includes a lid, a body, and a funnel that attach together to form a single device that cooperates with a mosquito net and collection bag. The MTD can also include a netting material box mounted by funnels and attach on top of bednets. Both embodiments trap mosquitoes and keep them in captivity. Once captured, the mosquitoes can be disposed of without biting humans and spreading disease, such as malaria. In this way, the disclosed MTD is effective at slowing or preventing the spread of malaria and other mosquito-borne diseases.
