{ "title": "ProVector Mosquito Trap", "inventor_name": "Thomas Kollars", "publication_year": 2009, "device_name": "ProVector", "goal": "Reduce deaths from mosquito-borne illnesses such as malaria, dengue fever and West Nile virus.", "problem_addressed": "Mosquito-borne diseases that cause high mortality, especially in tropical and subtropical regions.", "concept_summary": "The ProVector is an artificial-flower mosquito trap made of durable plastic that attracts adult mosquitoes with colored decals and a sugar-based nectar bait. Mosquitoes feed through a fine metal screen and ingest a Bacillus thuringiensis israelensis (Bt) biopesticide (ProVector Bt) which kills the insect, or a formulation (ProVector M) that blocks malaria parasite development while allowing the mosquito to survive. The device is low-cost, refillable, and designed for indoor use in homes and field settings.", "detailed_description": "The device resembles a flower and is constructed from the same type of impact used for football helmets. A four-color decal attracts mosquitoes. A metal screen with openings sized for mosquito mouthparts allows the insects to feed on an artificial nectar that contains sugar and the Bt biopesticide. Two models exist: ProVector Bt, which kills mosquitoes within days after ingestion, and ProVector M, which kills the malaria parasite inside the mosquito without killing the insect. The bait is refilled every three months at a cost of about $1. The device is sold for roughly $10 and is intended for use in homes, schools, and field camps in malaria-endemic regions. Field trials have been conducted in Puerto Rico, Afghanistan, Kenya, Thailand, and Uganda, and the technology has been independently validated by MIT Holding, Inc.", "category": "Mechanical Engineering", "principles": [ "Visual attraction using colored decals", "Sugar-based nectar bait", "Ingestion of Bacillus thuringiensis israelensis (Bt) biopesticide", "Targeted killing of adult mosquitoes", "Parasite interference (ProVector M) to block malaria development" ], "scientific_domains": [ "Entomology", "Public Health", "Vector Biology", "Microbiology", "Pest Management" ], "mechanisms_of_action": [ "Mosquitoes feed on bait containing Bt, which produces toxins that kill the insect after ingestion", "ProVector M delivers a compound that interferes with the life cycle of the malaria parasite inside the mosquito" ], "materials": [ "Durable plastic (football-helmet grade)", "Metal screen (fine mesh)", "Sugar solution", "Bacillus thuringiensis israelensis (Bt) biopesticide", "Color decals (pigments)", "Chemical attractants (unspecified)" ], "energy_sources": [], "inputs": [ "Adult mosquitoes", "Sugar-based bait", "Bt biopesticide formulation", "Color attractants" ], "outputs": [ "Dead adult mosquitoes (ProVector Bt)", "Mosquitoes carrying non-infectious malaria parasites (ProVector M)" ], "claimed_performance": "Blind trials by Walter Reed Army Institute of Research reported 50-100 % mosquito mortality within days.
