Fig. 3: Wolbachia does not impact sperm production, sperm transfer, or female sperm storage.

Sperm quantities in the seminal vesicle of virgin males (a) transferred to the bursa of the female reproductive tract during mating (b) and stored in the spermathecae of mated females (c). For the box plots, the middle horizontal line represents the median, the lower and upper margins of the box represent the 25th and 75th quartiles, and the whiskers extend to the minimum and maximum of the data (excluding outliers, shown as points outside the whiskers).
