Murgantiol and LED Stink Bug Trap for Indoor Overwintering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current stink bug traps are ineffective during the overwintering period as stink bugs are no longer attracted by known pheromone attractants when they move indoors, and there is a lack of semiochemical attractants active during this time.
Innovation Solution
The use of murgantiol, a sesquiterpene epoxyalcohol identified as an aggregation pheromone component of the Harlequin bug, is employed in combination with light-emitting diodes (LEDs) to attract and trap stink bugs indoors during the overwintering and transition periods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If known pheromone attractants are used in stink bug traps, then trapping effectiveness is improved during outdoor active periods, but trapping effectiveness deteriorates during indoor overwintering periods
Solution Approach 1:
The patent applies universality by developing a trap system that functions effectively in multiple contexts: both outdoor active periods and indoor overwintering periods. The combination of murgantiol pheromone attractant with LED lighting creates a multi-functional trap that adapts to different stink bug behaviors across seasons and locations, resolving the contradiction between reliability in specific conditions and adaptability across varying conditions.
Solution Approach 2:
The patent employs parameter changes by altering the attractant composition parameters - specifically combining chemical pheromone attractants (murgantiol) with physical light attractants (LEDs). This parameter change in the attractant system enables the trap to remain effective when stink bugs transition from outdoor to indoor environments during overwintering, addressing the reliability-adaptability contradiction.
2Productivity
If conventional attractants are used, then trapping works during summer active periods, but trapping fails during winter overwintering periods when stink bugs move indoors
Solution Approach 1:
The patent applies continuity of useful action by ensuring the trap remains effective throughout the entire annual cycle of stink bug activity. The combination of murgantiol and LED lighting provides continuous attractant activity that follows stink bugs from outdoor summer activity through indoor winter overwintering, eliminating the gap in effectiveness that occurs with conventional season-specific attractants.
3Measurement precision
If only chemical pheromone attractants are used, then attraction is specific to certain stink bug species and behaviors, but attraction fails when stink bugs change behavior during overwintering
Solution Approach 1:
The patent applies merging by combining two different attraction mechanisms: chemical pheromone attraction (murgantiol) and physical light attraction (LEDs). This combination leverages the specificity of pheromones for target species while adding the behavioral adaptability of light attraction, which remains effective when stink bugs change their behavior during overwintering transitions.
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
Murgantiol effectively attracts both sexes of the brown marmorated stink bug and synergizes with light to enhance trapping efficiency, providing the first known indoor attractant for stink bugs during these periods, significantly increasing trap catches compared to controls.
