Mean number (±s.d.) of uneaten H. diminuta eggs by Tenebrio molitor after experimental exposure to 433 ± 8 eggs for 1 h
| Treatment group | Uneaten eggs | Expected number of cysticercoid | Observed number of cysticercoids | Difference between expected and observed cysticercoid |
|---|---|---|---|---|
| Single insecticide exposure before parasite infection | 28 ± 10* | 53–56 | 42 ± 35a | ↓20 – 25% |
| Double insecticide exposure before parasite infection | 58 ± 19** | 46–49 | 11 ± 12b | ↓76 – 78% |
| Single insecticide exposure after parasite infection | 27 ± 13* | 53–56 | 83 ± 23c | ↑58 – 48% |
| Double insecticide exposure after parasite infection | 27 ± 10* | 53–56 | 100 ± 20c | ↑90 – 78% |
| Only parasite infection (control group) | 28 ± 14* | 53– 56 | 58 ± 23a | ↑10 – 3% |
The total number of beetles used for counting uneaten eggs in each treatment group were 30, 23, 20, 20 and 20 from top to bottom row, respectively. Predicted number vs observed mean number (±s.d.) of H. diminuta cysticercoids in T. molitor in the different treatment groups by using formula (y = 0.0007x1.8548), where y = number of established cysticercoids, and x = exposed egg number (Dhakal et al., 2018). Different numbers of asterisks, and different letters represent statistically different ingestion of eggs and establishment between groups, respectively (α = 0.05).
