Fig. 3From: Synergism between nonane and emanations from soil as cues in oviposition‐site selection of natural populations of Anopheles gambiae and Culex quinquefasciatusOviposition response of Anopheles gambiae s.l. to a substrate containing soil, nonane or soil + nonane in a dual-choice field study. Distilled water + autoclaved soil was used as control. Boxplots represent the median number + quartiles of larvae per clay pot per day; Median and quartiles are given; asterisks indicate statistical differences between treatment and control for a given pair (*p < 0.05, Wilcoxon signed rank test)Back to article page
