Ligninsulfonate Fly Attractant Composition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fly attractant and expellant compositions are not effective in attracting and repelling flies efficiently, as they lack a compound that can exhibit a strong attracting and expelling effect on flies.
Innovation Solution
A fly attractant and expellant composition containing ligninsulfonate as the active ingredient, combined with insecticidal active ingredients like neonicotinoid compounds and fly sex pheromones, which are applied in specific ratios to enhance attracting and repelling efficacy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional fly attractant compositions using pyrethroid compounds and fly sex pheromones are used, then some attracting effect is achieved, but the attracting effect is insufficient and flies are not effectively repelled
Solution Approach 1:
The patent changes the chemical parameters of the attractant composition by introducing ligninsulfonate as a new active ingredient and optimizing the concentration ratios of multiple components (ligninsulfonate: 5-20%, insecticidal active ingredient: 0.1-5%, fly sex pheromone: 0.01-1%). This parameter optimization resolves the contradiction by enhancing the attracting effect while maintaining effective fly control through synergistic interactions between components.
Solution Approach 2:
The patent creates a composite attractant composition combining three types of active ingredients: ligninsulfonate (new component), insecticidal active ingredients (pyrethroids or neonicotinoids), and fly sex pheromones. This composite approach resolves the technical contradiction by achieving superior attracting and expelling effects through the synergistic interaction of multiple substances, transforming the insufficient single-component or two-component formulations into an effective multi-component system.
2Reliability
If higher concentrations of insecticidal active ingredients are used to improve expelling effect, then fly control effectiveness increases, but the attracting effect may be compromised and non-target organisms may be harmed
Solution Approach 1:
The patent optimizes the concentration parameter of insecticidal active ingredients to a specific range (0.1-5%, preferably 0.5-2%) and establishes the critical ratio relationship between ligninsulfonate and insecticidal ingredient (ligninsulfonate content should be 4-50 times that of insecticidal ingredient). This parameter optimization resolves the contradiction by maintaining effective expelling effect while minimizing harm to non-target organisms through precise dosage control and synergistic enhancement from ligninsulfonate.
Solution Approach 2:
The patent introduces ligninsulfonate as an intermediary substance that mediates between the insecticidal active ingredient and the target fly population. Ligninsulfonate enhances the attracting effect to bring flies to the treatment area while the insecticidal ingredient provides the expelling effect. This intermediary approach resolves the contradiction by ensuring that the insecticidal component is delivered selectively to target flies through the attracting mechanism, reducing non-target impact.
3Productivity
If multiple active ingredients are combined to enhance attracting and expelling effects, then fly control effectiveness improves, but the composition complexity increases
Solution Approach 1:
The patent simplifies the composition formulation by establishing specific concentration ranges and ratio relationships among the three active ingredients: ligninsulfonate (5-20%), insecticidal active ingredient (0.1-5%), and fly sex pheromone (0.01-1%). The critical ratio parameter (ligninsulfonate:insecticidal ingredient = 4:1 to 50:1) provides a clear formulation guideline. This parameter-based simplification resolves the contradiction by making the multi-component composition manageable and easy to manufacture while maintaining superior fly control effectiveness.
