Moth Trap Light Source Photon Flux Density Guide Path
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional light traps for indoor Phycitinae moths, such as tobacco, Indian meal, dried currant, and Mediterranean flour moths, have low trapping efficiency due to behavioral suppression caused by high photon flux density, leading to ineffective insect capture in practical spaces like warehouses.
Innovation Solution
A trapping method and device that emits attracting light with a predetermined photon flux density, forming a guide path with directivity to attract and trap moths by limiting light irradiance below the behavior suppression threshold, using a light source with a narrow-angle light distribution and strategically placing trapping members within the guide path.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a light trap with high photon flux density is used to attract moths, then the attraction range is increased, but behavioral suppression occurs and trapping efficiency decreases
Solution Approach 1:
The patent applies local quality by creating different light intensity zones: a high-intensity attraction zone to draw moths from a distance, and a low-intensity guide path zone that prevents behavioral suppression. The light flux density is carefully controlled to remain below the suppression threshold in the guide path while maintaining high attraction range.
Solution Approach 2:
The patent employs dynamics by using multiple light sources with different emission characteristics (intensity, wavelength, directionality) that can be independently controlled. This allows the system to dynamically create the optimal light distribution pattern that balances attraction and avoidance of behavioral suppression.
2Area of stationary object
If a light source with wide-angle distribution is used, then the attraction coverage area is increased, but the light intensity becomes insufficient to form an effective guide path
Solution Approach 1:
The patent merges multiple light sources with different characteristics (wide-angle for coverage, narrow-angle for guide path formation) into a unified trapping system. This combination allows simultaneous achievement of broad attraction coverage and focused guide path intensity.
Solution Approach 2:
The patent adds dimensional complexity by considering multiple spatial dimensions and light propagation angles. Different light sources are positioned and oriented to cover horizontal and vertical spaces, creating a three-dimensional guide path structure that maintains intensity while expanding coverage.
3Productivity
If multiple light sources are added to increase attraction range, then the device complexity increases, but the trapping effectiveness improves
Solution Approach 1:
The patent applies universality by designing light sources that perform multiple functions: attracting moths from distance, forming the guide path, and preventing behavioral suppression. Each light source is optimized to contribute to multiple aspects of the trapping process, reducing the need for excessive numbers of separate components.

AI summary
According to an aspect of the invention, a method for trapping indoor adult Phycitinae, which is an adult moth belonging to Phycitinae subfamily includes: emitting attracting light at a predetermined photon flux density for a predetermined period of time or longer; forming a guide path to guide the adult Phycitinae to a vicinity of an emission end of the attracting light in a region having a photon flux density lower than the predetermined photon flux density on a side lower than a height of the emission end; and trapping the adult Phycitinae attracted by the attracting light in the guide path.
