Reproductive mode of Bryobia and Petrobia species.
| Species | Reproductive mode | Method | Males present | N |
|---|---|---|---|---|
| B. berlesei | A | culture | No | |
| B. kissophila | A | culture | No | |
| B. praetiosa | A | culture | No | |
| B. rubrioculus | A | culture | No | |
| B. sarothamni | S | culture | No | |
| B. spec. I | A | culture | No | |
| B. spec. II | A | field | No | 31 |
| B. spec. III | A | field | No | 16 |
| B. spec. IV | S | field | Yes | 12 |
| B. spec. V | A | culture | No | |
| B. spec. VI | A | field | No | 31 |
| B. spec. VII | A | field | No | 14 |
| P. harti | S | field | Yes | 58 |
| P. tunisea | S | field | Yes | 94 |
| P. spec. I | A/S* | field | No | 4 |
| P. spec. II | A | culture | No |
A = asexual, S = sexual. Reproductive mode was assessed by determining the presence of males directly in field samples only (field), or in combination with laboratory cultures initiated with field samples (culture). N indicates the total number of individuals investigated (in cases where males were counted from field samples only). * = mode of reproduction is uncertain because of the small sample size.
