Inside houses, malaria mosquitoes have a tendency to respond to convection heat of humans occupying bednets. Hence, their first point of contact with a bednet is on the ceiling directly above the torso and head of the sleeper. We developed a MCD that exploits this natural behavior; a simple black netting patch that can be placed on top of the bednet. Lab and semi-field tests show that a small (A4 –size) black netting patch can effectively lure and contaminate host-seeking mosquitoes upon contact. This design deploys control agents on a small point-source and offers an opportunity to turn existing nets into resistance-breaking products because alternative chemistries may be used with such patches. This MCD option thus provides a cost-effective method for targeting mosquitoes with novel control agents and be a complementary add-on to long-lasting bednets.
Also, untreated nets (which do not kill mosquitoes) may kill significant proportions of mosquitoes entering sleeping quarters with only a minimal amount of netting that can easily be fitted onto the net. This MCD option thus provides a cost-effective method for targeting mosquitoes with safe and approved impregnated netting and be a complementary addition to current untreated bednets.
