Efficacy Testing (PT18/PT19): Which Test Formats Suit Which Project?
Efficacy testing is the point in many projects where theory and practice converge: a product must not only be “well-intentioned” but must perform in the defined setup—comprehensibly, reproducibly, and aligned with the objective. BioGenius conducts efficacy testing for PT18 and PT19 and describes various test formats as well as multiple testing areas.
The Test Formats Mentioned—From Screening to Registration
Not every project begins at “registration.” Therefore, it is advisable to consider test formats according to the development stage. BioGenius identifies:
- Screening Tests
- Development Tests
- Comparative Tests
- Registration Tests
- Laboratory Tests
- Simulated-Use Tests
- Field Tests
This is a sound approach: screening/development provide rapid direction, comparative tests assist with benchmarking, and registration tests represent the structured step with consideration of requirements and documentation.
Testing Areas: What Is Covered in PT18/PT19?
BioGenius describes several testing areas that are practically oriented toward product types and applications:
- Insecticides
Examples: residual tests including long-term testing (surface treatment), choice test, direct spraying, spatial efficacy (e.g., spray/atomizer/fogger/LED), as well as testing of bed nets and textiles. - Attractants & Baits
Examples: choice test, bait stations, trap tests, pheromone traps. - Repellents
Examples: repellent effect on human skin (skin repellents), on fabric/textiles, barrier and repellent effect (surface treatment including long-term testing), as well as spatial repellents. - Textile Protection
Examples: repellent and mortality (including long-term effect), feeding protection, bait and attractant effect. - Additional Testing Options
Examples: acaricidal long-term effects (house dust mites), larvicide efficacy, residual efficacy testing in aircraft, as well as customer-specific setups upon request.
How to Select the Appropriate Setup?
In practice, a straightforward decision logic is helpful:
- What is the objective? Screening, development, comparison, or registration.
- What is the product? Insecticide, repellent, attractant/bait, textile protection.
- What is the application context? Surface, space, textile, skin, special environments.
- What time dimension is relevant? Immediate effect vs. long-term effect (e.g., residual tests/long-term testing).
The clearer these points are, the easier it becomes to select the test format so that results are subsequently usable—not merely “interesting.”
Guidelines/Regulations as Service Offerings
BioGenius identifies service offerings in the context of guidelines and regulations, including: BPR 528/2012, WHO, Woolmark TWC-TM25, ISO 3998, TL 8305-0331. For many projects, this is important because test design and documentation often cannot be considered in isolation.
