Fig. 2.

(A) Number of eggs laid by single female Anopheles coluzzii per cup in a dual-choice essay, using cups with conspecific first instars in ascending densities and cups containing water only (controls). Median and quartiles are given; asterisks indicate statistical differences between treatment and control for a given density (*P < 0.05, **P < 0.001, Wilcoxon signed rank tests). The number of replicates was 17. (B) Number of eggs laid by single female An. coluzzii per cup in a dual-choice essay, using cups with conspecific fourth instars in densities of 10 and 50 per cup, respectively, against cups containing water only (controls). Median and quartiles are given; asterisks indicate statistical differences between treatment and control for a given density (*P < 0.01, **P < 0.001, Wilcoxon signed rank tests). The number of replicates was 17. (C) The number of eggs laid by An. coluzzii in a dual-choice test between cups treated with low and high densities of conspecific first and fourth instars. Median and quartiles are given; asterisks indicate statistical differences between the larval stages at a given density (*P < 0.001, Wilcoxon signed rank tests). The number of replicates was 17.
