Solution Overview

Problem

Honey bee brood pheromone is unstable at room temperature, leading to rapid loss of bioactivity and making it impractical for commercial use, as it requires low-oxygen conditions and freezing for storage, limiting its shelf life and practical application.

Innovation Solution

Incorporating a food-grade antioxidant, such as tertiary-butyl hydroquinone, into the synthetic honey bee brood pheromone composition to stabilize it, allowing for prolonged storage and use on an inert substrate, thereby maintaining bioactivity and extending shelf life.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If synthetic honey bee brood pheromone is stored at room temperature, then storage convenience is improved, but bioactivity is rapidly lost

Engineering Contradiction:
Improvestorage convenienceVSAvoidbioactivity retention
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent introduces an inert substrate as an intermediary carrier that absorbs and releases the pheromone slowly, extending its effective period from minutes to months while maintaining bioactivity. The substrate acts as a mediator between storage requirements and biological effectiveness.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent changes the physical state and delivery parameters of the pheromone by incorporating it into an inert substrate matrix, transforming it from a volatile liquid that evaporates quickly to a stabilized formulation that releases pheromone gradually over extended periods at room temperature.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If synthetic honey bee brood pheromone is frozen to maintain stability, then bioactivity retention is improved, but storage complexity and cost increase

Engineering Contradiction:
Improvebioactivity retentionVSAvoidstorage requirements
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The inert substrate serves as a protective intermediary that shields the pheromone from degradation factors including temperature fluctuations, eliminating the need for freezing while maintaining stability and bioactivity throughout storage and application periods.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces expensive, complex refrigeration infrastructure with a simple, inexpensive inert substrate formulation that provides stable long-term storage at room temperature, reducing both equipment costs and operational complexity.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

3Reliability

If synthetic honey bee brood pheromone is used immediately after formulation, then bioactivity is maintained, but sustained commercial application is limited

Engineering Contradiction:
ImprovebioactivityVSAvoidshelf life
Core Design Contradiction:
ReliabilityVSDuration of action of stationary object

Solution Approach 1:

The inert substrate formulation enables continuous release of pheromone over extended periods, transforming the transient action of freshly formulated pheromone into sustained biological activity that maintains effectiveness for months, supporting ongoing commercial applications.

Inventive Principle:
Principle #20Continuity of useful action

Solution Approach 2:

The patent modifies the temporal parameters of pheromone activity by incorporating it into an inert substrate that controls release rates, extending the effective duration from minutes to months while preserving bioactivity through controlled gradual release rather than immediate evaporation.

Inventive Principle:
Principle #35Parameter changes

Function Achieved in This Case

The stabilized pheromone formulation retains bioactivity for over a year, enabling the development and sustained use of commercial products that enhance honey bee foraging behavior, pollination efficiency, and hive vigor, with no significant difference in biological effect compared to freshly formulated reagent-grade components.

Implementation Method 1

the synthetic honey bee brood pheromone is easily oxidizable and must be stored in low-oxygen conditions

AI summary

The invention relates to a stabilized synthetic honey bee brood pheromone and methods of stabilizing the synthetic honey bee brood pheromone, thereby enabling the production and sustained use of commercial products based on that pheromone. The stabilized synthetic pheromone can be used to manipulate the behaviour and improve the performance of worker honey bees, resulting in an overall increased vigour of the hive. The stabilized synthetic honey bee pheromone composition comprises two or more of ethyl linoleate, ethyl linolenate, ethyl oleate, ethyl palmitate, ethyl stearate, methyl linoleate, methyl lmolenate, methyl oleate, methyl palmitate and methyl stearate and an antioxidant.
