Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Noctuid pests, such as corn earworm, cotton bollworm, and fall armyworm, pose significant economic threats to row and vegetable crops due to their high reproductive and dispersal capacity, broad host ranges, and resistance to conventional pesticides and genetically modified crops, necessitating an effective and economically viable control method.

Innovation Solution

A semiochemical-based attract-and-kill (A&K) formulation that combines floral attractants and feeding stimulants with a low volume of pesticide, applied in a skipped row pattern, to draw noctuid moths to a point source for intense exposure to the insecticide, reducing the risk of resistance and environmental impact.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional pesticide sprays are applied to control noctuid pests, then immediate pest mortality is achieved, but pests develop resistance and environmental damage increases

Engineering Contradiction:
Improvepest control effectivenessVSAvoidenvironmental damage and resistance
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent uses semiochemicals (attractants and feeding stimulants) as intermediaries to lure noctuid pests to treated areas where low volumes of pesticide are applied. This mediator approach concentrates pest exposure to minimal pesticide quantities while achieving effective control, thereby reducing overall environmental impact and resistance development pressure

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The invention changes the application parameters from broad-spectrum high-volume spraying to targeted low-volume application (0.5-1.0 L/ha) combined with semiochemical attraction. This parameter change reduces pesticide exposure for non-target organisms and minimizes the selection pressure that drives resistance development

Inventive Principle:
Principle #35Parameter changes

2Reliability

If high volumes of pesticide are applied to ensure pest mortality, then pest control reliability improves, but cost and environmental impact increase

Engineering Contradiction:
Improvepest control effectivenessVSAvoidpesticide volume used
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

Semiochemicals serve as intermediaries that concentrate pest attraction to specific treated zones, enabling effective pest control with minimal pesticide volumes (0.5-1.0 L/ha) compared to conventional high-volume applications

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The invention applies pesticide locally in skipped row patterns only where pests are attracted by semiochemicals, rather than uniform broad-spectrum application. This local quality approach reduces total pesticide quantity while maintaining control effectiveness in critical zones

Inventive Principle:
Principle #3Local quality

3Adaptability or versatility

If broad-spectrum pesticide application is used to cover all noctuid species, then pest control coverage improves, but non-target insect damage increases

Engineering Contradiction:
Improvepest species coverageVSAvoiddamage to beneficial and non-target insects
Core Design Contradiction:
Adaptability or versatilityVSObject-generated harmful factors

Solution Approach 1:

Species-specific semiochemicals act as intermediaries that selectively attract target noctuid species to treated areas, enabling coverage of multiple pest species through targeted attraction rather than broad-spectrum toxic application that harms non-target insects

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

Instead of using toxic pesticides to kill pests across the landscape, the invention inverts the approach by using attractive semiochemicals to lure pests into localized treated zones, thereby protecting non-target insects in untreated areas while maintaining pest control effectiveness

Inventive Principle:
Principle #13The other way round (Inversion)
