Table 2 Two-group comparisons and overall trend of the effect of increasing larval environmental temperature on the odds of laying eggs by Anopheles gambiae s.s. females kept at all adult temperatures for the first two blood mealsa

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

  1. aAll females laid eggs after the third blood meal. bA negative value of the log odds represents a decrease in the proportion of females laying eggs with respect to the reference temperature, whilst a positive valuec represents an increase in egg laying rate
