  1. Groups of engorged females, confined to cylindrical tubes, were placed inside the incubator and on the soil base under the vegetation of grass at 14-day intervals. The lots of engorged females were formed every 14 days from September 2020 to April 2022; data were grouped for all lots from the same month over the 20-month period; values presented as the mean ± standard deviation; different letters in the same column indicate significantly different mean values (P < 0.05)
