Clock apparatus used in automated measurement of Anopheles gambiae ovipositional periodicity.
Figure 2
Ovipositional periodicity of laboratory strain groups. Mean percent of eggs oviposited per hour by a caged laboratory strain group (500 females per replicate; total eggs = 18,303).
Figure 3
Ovipositional periodicity of house-collected groups. Mean percent of eggs oviposited per hour by caged house-collected groups (100 females per replicate; total eggs = 11,007). Measurements of outdoor light intensity represented in the graph as a dark blue line, were taken on 5/11/2004 in Kisumu, Kenya.
Figure 4
Ovipositional patterns of individual A. gambiae over 24 h. Each horizontal cluster of rectangles represents a single individual. Shading classifies the number of eggs deposited per individual per hr (n = 56) during the oviposition interval. Gray shading represents the preoviposition interval.
Figure 5
Accumulated ovipositional patterns of individual A. gambiae over 24 h. Percent of eggs oviposited per hour by caged individual A. gambiae (total eggs = 4,815).
