A Specialist Testing✓GLP Accredited
since 2021
Facility in the Heart of East Africa

The Vector Control Product Testing Unit (VCPTU) is a specialised research unit within the Environmental Health and Ecological Sciences Department of the Ifakara Health Institute (IHI), located at its Bagamoyo Branch on the Tanzanian coast.

Established as an internationally recognised site, the VCPTU conducts high-quality, independent evaluations of novel and existing vector control products for private industry, product development partnerships (PDPs), and regulatory bodies — including the WHO Prequalification Programme.

All studies are conducted under the principles of Good Laboratory Practice (GLP), accredited by the South African National Accreditation System (SANAS G0033). Our work spans from research and development (R&D) through large-scale community trials, following rigorous methodology.

Novel Methodologies Developed at VCPTU

In addition to standard WHO evaluation guidelines, VCPTU has developed and validated in-house methodologies that address key gaps in insecticide-treated net bioefficacy assessment — improving throughput, reducing variability, and enabling accurate evaluation of next-generation products. VCPTU is also unique in operating all four standard experimental hut designs — Ifakara, Rapley, East African, and West African — at a single field site.

VCPTU Innovation

Ifakara Ambient Chamber Test (IACT)

A semi-field whole-net bioassay that evaluates complete ITNs under conditions closely simulating real sleeping environments — using a human host and free-flying mosquitoes over a natural 12-hour nocturnal exposure. Developed as a higher-throughput alternative to experimental hut trials.

  • 50 m × 3 m × 2.1 m tunnel structure with 10 individual test chambers
  • Human-baited exposure — reflects authentic mosquito host-seeking behaviour
  • Measures mortality and blood-feeding inhibition simultaneously
  • Developed to evaluate the interaction between ITN fabric (damage) and chemistry
  • Designed to do ITN durability monitoring
  • 99% mosquito recapture rate; high statistical power
  • Useful for field-aged nets
VCPTU Innovation

Miniature Experimental Hut (MEH)

A novel semi-field bioassay developed at VCPTU for evaluating IRS pro-insecticides such as chlorfenapyr. Because chlorfenapyr requires metabolic activation by free-flying, host-seeking mosquitoes, standard WHO cone and cylinder tests — which confine and restrict movement — severely underestimate its efficacy. The MEH provides an ecologically realistic, controlled exposure environment by housing miniature huts with treated wall panels inside the IACT tunnel, with a rabbit as host bait for overnight free-flying exposure.

  • Compact hut (120 × 112 × 75 cm) with two 30 × 30 cm entry/exit openings, fitted within IACT compartments
  • Surface-area-to-volume ratio of 3.3 — approximately double that of standard experimental huts — maximising mosquito contact with treated surfaces
  • Restrained rabbit as host (18:00–09:00 h), covering nocturnal host-seeking peaks of Anopheles and Culex
  • Overnight free-flying exposure; mortality recorded at 24 h intervals up to 168 h post-exposure
  • Validated for mud, wood, and concrete substrates against multiple pyrethroid-susceptible and -resistant malaria vectors

VCPTU Innovation

Complete Series Method (CSM)

A novel approach to ITN regeneration time (RT) assessment that substantially reduces daily heterogeneity caused by mosquito batch variability. In the conventional WHO longitudinal method, RT is measured across multiple testing days with different mosquito cohorts — introducing inter-batch noise. The CSM pre-stages all regeneration time points, then tests the complete series in a single day using one mosquito batch.

  • All regeneration stages (1, 2, 3, 5, 7 days post-wash) prepared in advance and refrigerated
  • Complete series tested on one day with a single, consistent mosquito cohort
  • Reduces variance nearly twofold versus the WHO longitudinal method
  • Flexible scheduling — replicates need not run on consecutive days
  • Equivalent sample sizes to traditional methods; no loss of statistical power
  • Applicable to any ITN formulation undergoing durability monitoring

Experimental Hut Types

Technician collecting mosquitoes from a window exit trap on an Ifakara experimental hut Ifakara huts — row of huts at field site

Ifakara Huts (n = 30)

Each hut measures 3.25 × 3.5 × 2 m with brick walls lined with mud and a corrugated iron roof overlaid with thatch; the ceiling is corrugated iron lined with foil. Entry is via eave openings (300 × 10 cm) on three sides that funnel to a 300 × 5 cm slit — a total entry area of 4,500 cm² — directing mosquitoes inward. Exit is through four window exit traps (240 cm² total); re-entry is not possible. One volunteer sleeper per hut. Ifakara huts catch on average three times more mosquitoes than East African or West African hut designs (Govella et al., PLoS ONE 2010). Used primarily for ITN evaluations and also deployed for spatial emanator efficacy studies.

Rapley huts at Lupiro field site

Rapley Huts (n = 18)

First described by Rapley (1961) and adapted for East African conditions. Each hut measures 2.5 × 2.5 × 2 m with concrete-block walls and a corrugated iron roof overlaid with thatch; the ceiling is corrugated iron lined with plastic sheeting. Entry is via eave openings (200 × 15 cm) on four sides funnelling to a 200 × 3 cm slit — total entry area 2,400 cm². Exit is through window exit traps (320 cm² total); re-entry is not possible. One volunteer sleeper per hut. Well-suited for evaluating insecticide-treated nets (ITNs), Indoor Residual Spray (IRS) formulations, and spatial emanators. Operated at the Lupiro (Ulanga) field site.

West African style huts East African style huts — concrete block with verandah traps

West African & East African Style Huts (n = 8 & 4)

East African huts (3 × 3 × 2 m) have brick walls lined with mud and a corrugated iron roof; the ceiling is wood lined with hessian or plastic sheeting. Entry is via eave openings (140 × 20 cm) on each wall funnelling to a 20 × 5 cm slit on two sides (total entry area 400 cm²). Exit is through both a verandah trap and window exit traps (880 cm² total); re-entry is not possible — a design in use in Tanzania since 1963 (Smith, 1965). West African huts (2.5 × 1.75 × 2 m) have concrete-block walls and a corrugated iron roof lined with plastic sheeting. Entry is via four slits (1 × 60 cm; two at the front, one on each side; total 240 cm²). Exit is through a verandah (225 cm²); notably, re-entry is possible, distinguishing this design from all others.

30 Ifakara Ambient Chamber Tests (IACT)

A novel ITN bioassay system developed and externally validated. The IACT uses a net-covered tunnel under ambient conditions, allowing examination of the interaction between ITN fabric and chemistry using free-flying mosquitoes.

8 Semi-Field Systems (SFS)

Large screened enclosures at the Bagamoyo site that simulate outdoor peridomestic environments. Used for controlled evaluation of spatial emanators, traps/lure-and-kill, and other outdoor vector control tools against colonised and wild mosquitoes under ambient conditions.

Molecular Biology Laboratory

Fully equipped molecular laboratory for species identification (PCR), insecticide resistance mechanism profiling (kdr, ace-1), Plasmodium detection by ELISA and PCR.

Insectary & Mosquito Colonies

Produces over 5 million disease-free mosquitoes per year across 10 colony strains. Species maintained: An. gambiae s.s. (Kisumu, Ifakara — susceptible; Muleba Kis — pyrethroid resistant), An. arabiensis (Dongola — susceptible; Kingani — pyrethroid resistant), An. funestus (FUMOZ — pyrethroid resistant), Aedes aegypti (Kingani — susceptible; Kinondoni — pyrethroid resistant), and Culex quinquefasciatus (Bagamoyo — pyrethroid resistant).

Experimental hut site — Lupiro (Ulanga)

Lupiro village (Ulanga District) hosts 60 experimental huts (30 Ifakara, 18 Rapley, 4 East African, and 8 West African style) — alongside a dedicated field laboratory, operating in high An. arabiensis density all year round.
