Solution Overview

Problem

Current methods lack effective and environmentally friendly solutions for monitoring and controlling the navel orangeworm (Amyelois transitella), a major pest affecting California's tree nuts, leading to economic losses and aflatoxin contamination due to feeding damage and reproductive disruption.

Innovation Solution

Blends of volatile organic compounds, such as racemic 1-octen-3-ol, ethyl benzoate, methyl salicylate, and ethyl palmitate, are used to attract and disrupt the mating and oviposition behaviors of navel orangeworm moths, providing a non-toxic and long-term control mechanism.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional insect control methods are used, then pest damage is reduced, but environmental pollution and resistance development occur

Engineering Contradiction:

Improvepest control effectivenessVSAvoidenvironmental pollution

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces chemical insecticide applications with a biological control mechanism using volatile organic compound blends that mimic natural plant emissions. This substitution eliminates the harmful effects of synthetic chemicals while maintaining pest control effectiveness through the attraction and disruption of navel orangeworm behavior.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The volatile organic compound blend acts as an intermediary substance that mediates between the monitoring system and the pest population. Rather than directly killing pests with toxins, the blend intermediates the control process by attracting moths to traps and disrupting their mating and oviposition behaviors, thereby reducing pest damage without environmental contamination.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Productivity

If single compound attractants are used, then the system is simple, but attraction effectiveness is insufficient

Engineering Contradiction:

Improvemoth attraction effectivenessVSAvoidblend composition complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent merges multiple volatile organic compounds into a synergistic blend that combines the attractive properties of individual compounds. The blend includes racemic 1-octen-3-ol, ethyl benzoate, methyl salicylate, and ethyl palmitate in specific ratios, where each compound contributes to the overall attraction effectiveness, creating a more potent formulation than any single compound alone.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent optimizes the concentration ratios of individual compounds within the blend to achieve maximum attraction effectiveness. By carefully adjusting the parameters of compound proportions (e.g., 3:1 minimum ratio of 1-octen-3-ol to ethyl benzoate), the formulation achieves enhanced productivity in moth attraction while managing the complexity through defined compositional parameters.

Inventive Principle:

Principle #35Parameter changes

3Productivity

If toxic insecticides are applied, then pest mortality increases, but resistance development and secondary contamination occur

Engineering Contradiction:

Improvepest mortality rateVSAvoidresistance and secondary contamination

Core Design Contradiction:

ProductivityVSObject-generated harmful factors

Solution Approach 1:

The patent converts the natural behavioral responses of pests to plant volatiles into a beneficial control mechanism. Instead of using toxic substances that harm the environment, the method utilizes the pest's innate attraction to certain volatiles to guide them into traps, where they are removed from the population without exposing the ecosystem to harmful chemicals or resistance pressures.

Inventive Principle:

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

Solution Approach 2:

The volatile organic compound blend leverages the pest's own behavioral instincts and sensory systems against them. The navel orangeworm's natural attraction to certain plant volatiles is harnessed to deliver the control action, allowing the pest's own biology to serve the control function without requiring external toxic agents that could lead to resistance or secondary contamination.

Inventive Principle:

Principle #25Self-service
