Bioassay WHO Cones Test Frames or Surfaces
Adjustable Testing Angles
| Angle | Function / Recommended Use |
|---|---|
| 0° (Horizontal) | Used for testing horizontal treated surfaces, such as table-mounted samples, treated fabrics laid flat, filter papers, and laboratory-prepared insecticide-treated materials. |
| 45° (Inclined) | Simulates inclined or sloping treated surfaces, providing a moderate landing angle commonly used in laboratory evaluations and comparative studies. |
| 60° (WHO Recommended) | Recommended for standard WHO cone bioassays on insecticide-treated nets (ITNs), long-lasting insecticidal nets (LLINs), and indoor residual spray (IRS) treated surfaces. This inclination encourages natural mosquito resting behavior while preventing prolonged contact with the cone surface. |
| 90° (Vertical) | Used for testing vertical treated surfaces, including sprayed walls, wall linings, curtains, wall-mounted treated materials, and Indoor Residual Spray (IRS) evaluations under field-like conditions. |

Product Details
The WHO Cone Test Frame for Insecticide Bioassay Studies has been developed to support standardized mosquito exposure assays in accordance with WHO cone bioassay protocols. The system provides a stable and versatile platform for evaluating the efficacy of insecticide-treated materials used in vector control programs.
The testing system consists of two independent acrylic frames, each measuring 60 × 60 cm, with four cone mounting positions per frame, allowing a total of eight simultaneous test replicates. Each cone position is precisely located to provide uniform spacing and consistent mosquito exposure during testing.
The frame incorporates an adjustable angle mechanism, enabling researchers to position the test surface at 0°, 45°, 60°, or 90°, depending on the study requirements. This feature allows bioassays to be conducted on both horizontal and vertical treated surfaces while maintaining secure cone attachment throughout the experiment.
Each mounting position accommodates standard WHO mosquito cones, which are securely fixed using removable clips to prevent movement or damage to the test material. The frame is manufactured using high-quality solvent-resistant acrylic, making it suitable for repeated use with a wide range of insecticide formulations and cleaning agents.
Designed for quick assembly and easy handling, the modular construction allows convenient transportation, storage, and maintenance. The system is suitable for research laboratories, public health institutes, universities, vector control programs, and insecticide evaluation facilities.
