Table 3 Two-group comparisons and overall trend of the effect of increasing larval environmental temperature on the mean number of eggs laid by adult Anopheles gambiae s.s. females (reared from these larvae) kept at all adult temperatures. No mosquitoes held at 31 °C survived long enough to blood feed for a third time

From: Larval and adult environmental temperatures influence the adult reproductive traits of Anopheles gambiae s.s.
