Figure 9.
Mean (+ SD) number of days of Rhipicephalus annulatus egg incubation (black bars) and larval (white bars) stages in only positive study arenas from each cohort. The duration of the egg incubation period was defined as the day an engorged female was placed in a study arena until the day the first larvae were collected in each study arena. Larval stage was defined by the day the first larvae was collected in each study arena until the last day larvae was collected from the same study arena. ** = p <0.01 = incubation stage cohort 6 vs incubation stage cohort 3, 4, 7, 9; A vs. B = p <0.01 in larval stage cohort 3 vs. larval stage 1, 4, 6, 7, and 9. Number of ticks collected and number of positive study arenas per cohort presented in Table 1. Cohorts 2 and 8 excluded from analysis.
