The Use of Granular Cyclopentanone as Alternative to Artificial Source of Carbon Dioxide in Improved Passive Outdoor Host Seeking Device (POHD)

Figure 5

Estimated proportion (±1 s.e.) of An. arabiensis mosquitoes that were attracted and killed after exposure to an improved passive host seeking device that was untreated or treated with bendiocarb (BE) and baited with fresh or 2-month-old granules of cyclopentanone (Cy) or their combinations with fresh granules of Mbita blend (Mb) in a rectangular bioassay box within the semifield system. The statistical significant differences between treatments are indicated as follows: the black boxes indicate statistical significant differences from all other treatments; the different numbers of asterisks indicate statistical significant differences between treatments; no asterisk or color indicates statistical significant differences from all other treatments. The treatments are abbreviated as follows: untreated: attractants without bendiocarb-treated netting, Mb: Mbita blend, 2moCy: 2-month-old granules of cyclopentanone, 2moCyMb: 2-month-old granules of cyclopentanone combined with Mbita blend, FreshCy: fresh granules of cyclopentanone, and fresh CyMb: fresh granules of cyclopentanone combined with Mbita blend.
