Veterinary Composition for Sandfly Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current treatments for controlling sandflies and leishmaniasis in non-human mammals, such as dogs and cats, do not provide prolonged repellent and insecticidal effectiveness beyond four weeks.
Innovation Solution
A veterinary composition combining a neonicotinoid compound, specifically dinotefuran, with a pyrethroid compound, specifically permethrin, and an insect growth inhibitor, pyriproxyfen, applied topically and repeated at least five weeks apart, to achieve extended control of sandflies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If existing topical formulations (permethrin, pyriproxyfen, imidacloprid, fipronil) are used to control sandflies, then repellent and insecticidal efficacy is achieved, but the duration of protection does not exceed four weeks
Solution Approach 1:
The patent combines three distinct active ingredients (imidacloprid, permethrin, and pyriproxyfen) into a single topical formulation. This combination leverages the complementary mechanisms of action: imidacloprid provides sustained neural blockade, permethrin offers rapid contact toxicity and repellency, and pyriproxyfen delivers prolonged insect growth inhibition. The synergistic interaction between these compounds extends the duration of protection beyond four weeks while maintaining consistent efficacy throughout the treatment period.
Solution Approach 2:
The formulation creates a composite insect control system where multiple chemical compounds with different persistence profiles and modes of action work together. The combination of a neonicotinoid (imidacloprid), a pyrethroid (permethrin), and an insect growth regulator (pyriproxyfen) forms a composite material that provides multi-layered protection, with each component contributing to different aspects of sandfly control and extending the overall duration of effectiveness.
2Duration of action of moving object
If topical formulations are applied frequently to maintain efficacy, then protection duration is extended, but treatment complexity and animal stress increase
Solution Approach 1:
The formulation is designed to provide continuous protective action through the sustained release and persistent activity of its three active ingredients. The combination ensures that at least one component remains effective at all times, creating a continuous barrier against sandflies. This eliminates the need for frequent reapplication while maintaining uninterrupted protection, thereby reducing treatment complexity and minimizing animal stress.
Solution Approach 2:
The formulation incorporates compounds with different persistence characteristics that work in sequence. As one ingredient begins to degrade, another maintains protective levels, creating a staggered release pattern that ensures continuous efficacy. This preliminary design of the formulation allows a single application to provide extended protection without requiring frequent intervention.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The composition demonstrates residual repellent effectiveness of at least 89% after 37 days and 74% after 44 days, significantly surpassing the duration of protection offered by existing treatments.
Implementation Method 1
the inventors have shown that such a composition provides effective control of sandflies for more than four weeks, and in particular for at least five weeks, as illustrated by residual repellent efficacy against sandflies
Implementation Method 2
the composition further comprises an insect growth inhibitor... the insect growth inhibitor is methoprene or pyriproxyfen, preferably pyriproxyfen
