Figure 4

Linear relationships between temperatures above 40°C and log ₁₀ % mortality/min for eggs of Anopheles gambiae. Data denoted by filled squares are the slopes from Figure 3; data denoted by open squares were calculated from Figure 2, based on mortality per 10 min for house-collected stock and Kisumu laboratory strain. % mortality/min for the open squares = (mean survivorship in control - mean survivorship in each treatment)/10 min. Because each slope from Figure 3 was a composite derived from 10 original data, these points (filled squares) were weighted 10× in a weighted regression analysis.
