Dynamics of bacteriocyte number during aphid development.

(a) Variation in the number of bacteriocytes per aphid, in relation to host developmental stage. Results are displayed as box plots where central lines represent the medians, boxes comprise the 25–75 percentiles and whiskers denote the range; n = 20 aphids per stage, for a total number of 180 aphids dissected and analyzed. Data were analyzed by the Kruskal-Wallis test followed by a post hoc multiple comparisons test (Wilcoxon rank-sum test with Bonferroni correction). Developmental stages labeled with different letters are significantly different (P < 0.05). (b) Modeling of bacteriocyte number dynamics during aphid development. A logistic model was applied for the first part of the dynamics, followed by an exponentially decreasing model. Population growth, r and decreasing rates, l, are shown on the figure, with their 95% confidence interval. Shaded grey area indicates the laying period.
