Solution Overview

Problem

The spread of Varroa destructor, a parasite affecting honey bees, has become a significant issue due to its rapid global dissemination and the lack of effective treatments, causing significant harm to bee populations and impacting beekeeping and pollination.

Innovation Solution

The use of extracts from Dittrichia viscosa, specifically costic acid, which demonstrates acaricidal activity against Varroa destructor, offering a potential solution for controlling the parasite population.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If commercial acaricides are used to control Varroa destructor, then parasite population is reduced, but honey bees may be harmed

Engineering Contradiction:

Improveparasite control efficacyVSAvoidharm to honey bees

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent extracts and isolates costic acid from Dittrichia viscosa plant material as the active acaricidal component. This extraction principle allows obtaining a purified natural substance that effectively controls Varroa destructor without the harmful side effects associated with commercial synthetic acaricides, thus resolving the contradiction between parasite control efficacy and harm to honey bees

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent utilizes the natural properties of costic acid, a compound naturally produced by the Dittrichia viscosa plant, to create an acaricidal substance. This converts the plant's natural defense mechanism (which could be seen as harmful to insects) into a beneficial treatment for beekeeping, providing effective parasite control while maintaining bee health through a natural substance

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

2Object-affected harmful factors

If natural substances like Dittrichia viscosa extracts are used, then honey bees are protected from harm, but acaricidal efficacy may be reduced

Engineering Contradiction:

Improveharm to honey beesVSAvoidparasite control efficacy

Core Design Contradiction:

Object-affected harmful factorsVSReliability

Solution Approach 1:

The patent applies extraction to isolate costic acid from the complex mixture of compounds in Dittrichia viscosa. This purification process concentrates the active acaricidal component, ensuring that the natural substance maintains high efficacy against Varroa destructor while preserving the safety profile of the natural origin, thus resolving the contradiction between bee safety and parasite control effectiveness
