Table 2.
Molting and oviposition success of Amblyomma triste ticks infected by Rickettsia parkeri (infected group) and noninfected (control group) through four consecutive generations (F1 to F4) in the laboratory.
| Tick generation |
Number nymphs that molted to adults/Number recovered engorged nymphs (% molting success) |
Number females that oviposited/Number recovered engorged females (% oviposition success) |

|---|---|---|---|---|
| Infected | Control | Infected | Control | |
| F1 | 274/558 (49.1) | 537/656 (81.9)* | 18/19 (94.7%) | 9/9 (100) |
| F2 | 1154/1580 (73.0) | 1089/1093 (99.6)* | 18/21 (85.7%) | 7/7 (100) |
| F3 | 100/240 (41.7) | 299/321 (93.1)* | 10/10 (100) | 7/7 (100) |
| F4 | 404/552 (73.2) | 411/457 (89.9)* | 10/10 (100) | 5/5 (100) |

| Total | 1932/2930 (65.9) | 2336/2527 (92.4)* | 56/60 (93.3) | 28/28 (100) |
*means that molting or oviposition success values for infected and control ticks (horizontal lines) of the same tick stage were significantly different (P < 0.05).
