Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for controlling adult mosquito populations, such as Ultra Low Volume (ULV) technology, face challenges in maintaining effective aerosol persistence and droplet density for airborne insecticide delivery, and there is a need for compositions that are non-toxic and environmentally friendly.
Innovation Solution
An insecticidal composition comprising an insecticide, a polyalkylene block copolymer wetting agent, a polyalkylene carbonate, and a polyalkylene glycol, which enhances insect mortality by improving the physical properties of the aerosol, including density and evaporation rate, allowing for effective aerial or ground application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional insecticidal compositions are used for aerial application, then insecticidal efficacy can be achieved, but the compositions lack sufficient aerosol persistence and appropriate droplet density for effective contact with flying mosquitoes
Solution Approach 1:
The patent modifies the physical and chemical parameters of the insecticidal composition by incorporating specific carriers and adjuvants. The composition includes a carrier selected from water, alcohol, or oil-based carriers, along with specific adjuvants such as wetting agents, surfactants, and stabilizers. These parameter changes enable the aerosol to persist in the air column for appreciable lengths of time while maintaining suitable droplet densities for effective mosquito contact.
Solution Approach 2:
The patent creates a composite insecticidal composition by combining multiple components: insecticide active ingredients, carriers (water, alcohol, or oil-based), wetting agents, surfactants, and stabilizers. This composite formulation ensures both aerosol persistence and appropriate droplet density, resolving the contradiction between efficacy and duration of action.
2Productivity
If conventional pesticide formulations are applied, then mosquito control can be achieved, but the compositions contain toxic substances that raise environmental and safety concerns
Solution Approach 1:
The patent changes the chemical composition parameters by replacing highly toxic conventional pesticides with alternative insecticidal active ingredients that have reduced toxicity profiles. The composition incorporates these alternative actives along with benign carriers and adjuvants, maintaining mosquito control effectiveness while reducing harmful effects on non-target organisms and the environment.
Solution Approach 2:
The patent employs readily available, environmentally benign carriers such as water, alcohol, or food-grade oil-based carriers that can be easily disposed of or degrade naturally. These carriers replace persistent toxic substances, allowing for effective mosquito control without long-term environmental contamination or safety concerns.
3Ease of operation
If aerosols are released for mosquito control, then contact with flying mosquitoes is achieved, but the droplets do not remain airborne long enough to maintain effective density
Solution Approach 1:
The patent adjusts the physical parameters of the aerosol by incorporating specific adjuvants including wetting agents and surfactants that modify droplet evaporation rates and air dynamics. These parameter changes enable droplets to remain airborne for appreciable lengths of time while maintaining sufficient density for effective mosquito contact, directly addressing the duration problem.
Solution Approach 2:
The patent introduces intermediary substances such as wetting agents and surfactants that act as mediators between the insecticide and the air environment. These intermediaries modify the physical behavior of droplets, extending their airborne duration and ensuring they maintain effective density throughout the air column, thereby improving aerial application effectiveness.
Applied Scientific Principles

Function Achieved in This Case
The composition increases insect mortality compared to traditional formulations, providing a more efficient and environmentally friendly means of mosquito control by prolonging aerosol persistence and ensuring suitable droplet densities for effective contact with flying mosquitoes.
Implementation Method 1
a polyalkylene block copolymer wetting agent
Implementation Method 2
the wetting agent in the insecticidal composition increases insect mortality
Implementation Method 3
volumes of material used remain low. It is desired for the aerosol to persist in the air column for an appreciable length of time
