1. Mode of Action of Chlorfenapyr Explained
By Dr. Idelphonse Ahogni, PhD
📝 Full Lecture Transcript:
Chlorfenapyr belongs to the pyrrole class. Unlike neurotoxic insecticides that target ion channels or synaptic transmission, chlorfenapyr is a pro-insecticide. Once metabolized inside the mosquito, cytochrome P450 enzymes convert it into CL 303268. This active metabolite enters the mitochondria and uncouples oxidative phosphorylation, halting ATP production. The vector dies of cellular metabolic exhaustion without exhibiting cross-resistance to conventional pyrethroids.

2. The Science of Human Landing Catches (HLC)
By Dr. Idelphonse Ahogni, PhD
📝 Full Lecture Transcript:
Human Landing Catches (HLC) remain the gold standard for measuring human-vector contact. Conducted by trained collector pairs operating in shifts from 18:00 to 06:00, HLC establishes hourly biting rhythms, indoor vs. outdoor biting ratios (endophagy vs. exophagy), and when paired with laboratory CSP-ELISA, the Entomological Inoculation Rate (EIR). Collectors receive regular malaria screening and prophylactic coverage.

3. The Urban Threat of Anopheles stephensi in Africa
By Dr. Idelphonse Ahogni, PhD
📝 Full Lecture Transcript:
Historically, malaria transmission in sub-Saharan Africa has been predominantly rural, driven by Anopheles gambiae and An. funestus. The invasion of Anopheles stephensi fundamentally alters this paradigm: this vector thrives in clean man-made water containers across dense urban environments (overhead tanks, cisterns, tires). Its detection across coastal West Africa requires cross-border surveillance and a transition towards urban larval source management.

Rainy Season AlertAugust 2026 · 📍 Southern & Central Benin (Ouémé, Atlantique, Zou)
Seasonal transmission peak: Scaled-up larval surveillance and dual-active LLIN deployment
With the return of heavy rains, temporary freshwater breeding sites suitable for Anopheles coluzzii and An. gambiae are proliferating. Vector survival and the entomological inoculation rate (EIR) are surging.
Points d'Action & Recommandations :
- Verify physical integrity and proper hanging of next-generation mosquito nets (PBO / Interceptor G2)
- Environmental cleanup around households and destruction of standing artificial water collections
- Early consultation at healthcare facilities upon initial febrile symptoms in children under 5
Invasive Vector AlertJune 2026 · 📍 Coastal corridors & Cotonou
Heightened vigilance on invasive Anopheles stephensi in seaport and urban corridors
WHO initiative alert on the dissemination of An. stephensi in West Africa. This urban vector thrives in clean water storage barrels, cisterns, and domestic overhead tanks.
Points d'Action & Recommandations :
- Systematic hermetic covering of all domestic and construction water containers
- Larval surveys and immediate molecular PCR typing for any morphologically suspicious specimens
- Community sensitization for municipal stakeholders, port authorities, and building sites
WHO Policy BriefMay 2026 · 📍 African Region (AFRO)
Summary of WHO guidance on dual-active insecticide nets and seasonal chemoprevention (SMC)
WHO reiterates the priority of targeted chlorfenapyr net allocation in settings with documented pyrethroid resistance.
Points d'Action & Recommandations :
- Prioritize dual-active LLIN procurement based on genomic resistance mapping
- Synergistic integration of vector control with malaria vaccines (R21 / RTS,S)
