Probit analysis of mortality for a laboratory-susceptible population of R. ferrugineus adults and 4th larvae after exposure to T. vulgaris and O. basilicum extract.
| Extract | Adult | 4th Larvae | ||||||
|---|---|---|---|---|---|---|---|---|
| LC50 (µg/mL) 95% CF | Slope | Chi Square | p | LD50 (µg/Larvae) 95% CF | Slope | Chi Square | p | |
| T. vulgaris | 1032 (891–1223) | 25.4 ± 1.41 | 51.8 | <0.01 | 11.4 (9.97–12.74) | 9.32 ± 0.64 | 47.21 | <0.01 |
| O. basilicum | 1246 (1046–1501) | 2.51 ± 0.21 | 43.7 | <0.01 | 14.6 (12.32–15.94) | 1.24 ± 0.23 | 41.58 | <0.01 |
