Jan-March 2012 | Commenced trap development with the introduction of Mosquitito trapâ„¢. | Â | Â |
April-June 2012 | Continued trap development with the first Suna trap. | Solid metal cone introduced because fabric absorbed the odours and consequently reduced trap efficacy. | More durable. |
Fabric base replaced with flexible plastic mesh base. | |||
July-September 2012 | Continued Suna trap development with the replacement of metal cones with plastic ones and plastic mesh base with a rigid one. | Metal cones are potentially attractive to thieves who could sell them to scrap metal dealers. | Lower unit cost for SMoTS. |
Plastic cones are cheaper than metal cones. | Rigid plastic base to increase durability but found to reduce airflow and performance. | ||
July-September 2012 | Complete SMoTS installed in 18 households for piloting. In nine households 20-Watt systems were provided and in the other nine, 30-Watt systems were provided. Also, four different types of bulb were provided. | Performance of various components and community perceptions of SMoTS. | Decision on final SMoTS components: 20-Watt systems and brighter bulbs selected for the intervention. |
Estimates of lengths of electrical cable needed per house. | |||
July-September 2012 | Removal of carbon dioxide from the blend. | Logistical challenges with procuring and distributing molasses to households. | Discontinued mobilisation of women’s groups that were being mobilised to distribute molasses for fermentation. |
Time constraints with regard to project timelines. | |||
Need for more intensive training to households on replacing molasses on a daily basis and concerns about adherence. | |||
Cost of procuring molasses. | |||
October-December 2012 | Finalised trap development with the modification of plastic base with fine grid of holes to increase airflow (Figure 3). | Rigid plastic base with fine grid of holes. | Increased airflow and performance with greater durability than a fabric base. |
