Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current chemical pesticides face challenges in effectively controlling thrips due to pesticide resistance and the pests' behavioral habit of hiding in narrow crevices, reducing exposure to sprayed chemicals.

Innovation Solution

A contact pheromone-containing composition using 7-methyltricosane (7TM) is applied to disrupt the seclusion behavior of thrips, combined with a pesticide like Spinetoram, to increase the exposure and effectiveness of the pesticide.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If chemical pesticides are used to control thrips, then insecticidal effect is achieved, but pesticide resistance develops and control efficiency decreases

Engineering Contradiction:

Improvecontrol efficiencyVSAvoidpesticide resistance

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent uses contact pheromones as an intermediary substance that disrupts thrips behavior and serves as a mediator to enhance pesticide effectiveness. The pheromone modifies the thrips' response to pesticides, making them more susceptible to chemical control without directly killing the pests themselves.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The invention creates a composite control system by combining contact pheromones with chemical pesticides. This composite approach integrates two different mechanisms of action (behavioral disruption and direct toxicity) to achieve synergistic control effects and overcome pesticide resistance.

Inventive Principle:

Principle #40Composite materials

2Reliability

If thrips hide in narrow crevices, then they avoid pesticide exposure, but control efficiency is reduced

Engineering Contradiction:

Improvecontrol efficiencyVSAvoidpesticide exposure

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

Contact pheromones act as an intermediary that reaches thrips in their hiding places and modifies their behavior, making them emerge from crevices or become less protective, thereby increasing their exposure to subsequently applied pesticides.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The contact pheromone is applied first to disrupt thrips seclusion behavior before pesticide application. This preliminary action prepares the target population by making them more accessible and vulnerable to the subsequent pesticide treatment.

Inventive Principle:

Principle #10Preliminary action

AI summary

Proposed are a contact pheromone-containing composition, a kit composition, and a method using the same for controlling thrips. A thrip control technology using a behavior-disrupting pheromone is provided to increase opportunities for the exposure of the thrips to pesticides. Contact pheromone (7MT) induced significant behavioral changes in adult thrips. Moreover, the addition of the contact pheromone increased an insecticidal effect. The composition contains the contact pheromone as an active ingredient, and the kit composition contains the contact pheromone of the thrips and pesticides against the thrips. The contact pheromone-containing composition shows a significant control effect on thrips. The kit composition and method, which use a contact pheromone and pesticide together, show a significantly increased control effect compared to the thrips control technologies that only apply existing pesticides.
