Beauveria Bassiana Strains for Broad-Spectrum Insect Pest Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing chemical insecticides pose health and environmental risks, and not all strains of Beauveria bassiana are effective in controlling a wide spectrum of agricultural and non-agricultural insect pests.
Innovation Solution
Utilizing strains of Beauveria bassiana deposited as CNCM I-2960 or CNCM I-2961, or a combination thereof, to control crop and non-crop pests through contact with crops, plants, or loci, optionally with agriculturally acceptable excipients.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If chemical insecticides are used to control insect pests, then pest control efficacy is improved, but health and environmental risks increase
Solution Approach 1:
The patent converts the harmful effect of chemicals by replacing synthetic insecticides with a biological agent (Beauveria bassiana fungus). The fungus naturally occurs and infects insects, transforming a chemical harm-based solution into a biological, environmentally benign alternative that maintains pest control efficacy without the harmful side effects of chemical pesticides
Solution Approach 2:
The Beauveria bassiana fungus acts as a biological intermediary between the pest problem and the solution. Instead of directly applying chemicals to pests, the fungus serves as a living mediator that naturally infects and controls insect populations, providing an indirect but effective control mechanism that avoids direct chemical exposure to non-target organisms
2Object-affected harmful factors
If Beauveria bassiana strains are used as alternative to chemical pesticides, then health and environmental safety is improved, but pest control efficacy may be reduced
Solution Approach 1:
The patent applies parameter changes by optimizing specific characteristics of the Beauveria bassiana strain, including spore concentration (1×10^8 to 1×10^12 spores per milliliter), application timing, and environmental conditions. These parameter optimizations ensure the biological agent achieves pest control efficacy comparable to chemical pesticides while maintaining its safety profile
Solution Approach 2:
The patent applies local quality by formulating the fungal spores with specific excipients and adjuvants that enhance their performance in particular application contexts. The composition is tailored to local conditions (crop type, pest species, environmental factors) to maximize efficacy while preserving the inherent safety of the biological agent
3Reliability
If not all strains of Beauveria bassiana are used, then strain specificity is maintained, but wide-spectrum pest control capability is reduced
Solution Approach 1:
The patent achieves universality by selecting and combining Beauveria bassiana strains that demonstrate broad host range and adaptability to control multiple pest species across different crop types. The chosen strains possess universal characteristics that enable them to function effectively against diverse insect pests, including agricultural and non-agricultural species, thereby providing wide-spectrum pest control capability
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
