Corn Pest Control Using Sublethal Insecticides and Flower Strips
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Intensive corn cultivation leads to significant yield reductions and environmental issues due to corn borers, with chemical insecticides causing pest resistance and ecological imbalances, necessitating a green control method that enhances natural enemy populations and reduces pesticide use.
Innovation Solution
A method combining the use of high-efficiency, low-toxic insecticides with sublethal dosages and the construction of artificial flower and grass strips planted with nectariferous plants to increase sensitivity of corn borers to natural enemies, providing habitat and nutrients for these enemies, thereby enhancing their population and detoxification abilities, thereby reducing pesticide use and enhancing biodiversity protection and green crop production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If chemical insecticides are used to control corn borers, then pest damage is reduced, but pest resistance increases and environmental harm worsens
Solution Approach 1:
The patent changes the dosage parameter of chemical insecticides from full recommended dosage to sublethal dosage (50% or less), transforming the chemical's function from complete pest elimination to sensitivity enhancement, thereby reducing pest resistance while maintaining control effectiveness
Solution Approach 2:
The patent introduces natural enemies as an intermediary biological agent between the chemical insecticide and the corn borers. The sublethal chemical treatment prepares the pest population by increasing their sensitivity, making them more vulnerable to natural enemy attack, thus creating a synergistic control system
2Productivity
If full dosage of chemical insecticides is applied, then immediate pest control is achieved, but natural enemy populations are harmed
Solution Approach 1:
The patent reduces the chemical dosage parameter to sublethal levels, changing the outcome from direct pest mortality to pest sensitivity enhancement. This parameter change ensures that natural enemies are not killed by the chemical treatment while still achieving pest control through the enhanced sensitivity mechanism
Solution Approach 2:
The patent converts the potentially harmful full dosage chemical treatment into a beneficial sublethal treatment that inadvertently benefits natural enemies by making pests more vulnerable to them. The chemical treatment's harm is transformed into a benefit for biological control agents
3Productivity
If intensive corn cultivation is adopted, then agricultural efficiency is improved, but ecological balance is disrupted
Solution Approach 1:
The patent merges chemical control methods with biological control methods into an integrated pest management system. By combining sublethal chemical treatment with natural enemy conservation and promotion, the system achieves both high productivity and ecological balance through synergistic interaction between different control approaches
Solution Approach 2:
The patent creates a multi-functional pest control system that simultaneously achieves pest suppression, natural enemy population maintenance, and ecological balance. The artificial flower strips serve multiple functions: providing habitat for natural enemies, enhancing biodiversity, and supporting the biological control mechanism

AI summary
A method for green control of corn pests in an intensive farmland is provided, belonging to the technical field of green control. The method for green control of corn pests in an intensive farmland is based on a scheme that combines at least halved application of a high-efficiency and low-toxic insecticide with control by an artificial flower and grass strip. The method can generate a synergistic effect, reduce the use of insecticides, increase a sensitivity of corn borers to natural enemies, protect a natural enemy population, and coordinately control corn borer damages, thereby achieving biodiversity protection and green crop production.
