Welcome

The Vector Control Product Testing Unit (VCPTU) is an internationally renowned site for high quality evaluations of new vector control products for the private industry, product development partnerships, and regulatory bodies including WHO Prequalification.

What we do

We use standard WHO testing methodology (Phase I: laboratory studies, Phase II: experimental hut studies, and Phase III: community studies) for long lasting insecticidal nets and Indoor residual spray (IRS). We have also developed new bioassay techniques such as the Ifakara Ambient Chamber Test (I-ACT) and conduct non-inferiority testing for vector control products that generate data that compliments WHO guidance. We always do our testing on both susceptible and local resistant mosquito strains to show how products will perform in the African context where pyrethroid resistance is the norm. Our studies are conducted following principles of Good Laboratory Practice (GLP).

Mission

We serve the community through excellence in service delivery, research into new methods of product testing and training of MSc and PhD students.

Vision

In order to eliminate vector borne disease we must have a diverse range of high quality and long-lasting vector control tools. We help bring new vector control products to market more rapidly and cost efficiently we conduct rigorous evaluations using well powered studies, enhanced research standards, and careful data analysis. At the same time we are dedicated to building capacity in entomology for the future of vector control.

Available tests: indoor residual spraying (IRS), insecticidal treated nets (ITNs), skin (topical) repellents, spatial (area) repellents, treated clothing, attractive targeted sugar baits and mosquito lures.

vcptu-image

We develop new means of testing products and assist in developing guidelines for international use.

vcptu-image

We measure key parameters in the mosquito that translate to efficacy in reducing vector borne disease in the human population when applied at scale.
