Table 2. Percentages (mean ± SE) for the different categories of damages to Varroa destructor recorded in the colony debris of A. m. scutellata and A. mellifera hybrids of European origin in Kenya and USA respectively.
| Category of damage | Kenya (%) | USA (%) | P- Valuea |
|---|---|---|---|
| Damaged legs (DL) = total or partial loss of one or more legs | 5.7 ± 0.6 | 10 ± 1.4 | 0.003 |
| Hollow in the dorsal shield (HDS) = Depression in the dorsal shield | 0.5 ± 0.2 | 2.3 ± 0.7 | 0.01 |
| Empty dorsal shield (EDS)-carcass = mites that lacked all legs and all or almost all of the ventral shields, generally only the dorsal shield remained | 0.6 ± 0.2 | 0.1 ± 0.7 | 0.01 |
| Damaged shields (DS) = loss of dorsal shields, fissures in and loss pieces of the dorsal shield | 0.6 ± 0.2 | 0.3 ± 0.2 | 0.001 |
| Damaged shield + damaged legs (DS + DL) | 0.2 ± 0.1 | 0.4 ± 0.2 | 0.46 |
| Hollow in the dorsal shield + damaged legs (HDS + DL) | 0.1 ± 0.1 | 0.4 ± 0.2 | 0.08 |
| Damaged gnathosoma (DG) = loss of chelicerae and/or pedipalps | 0.3 ± 0.1 | 0.1 ± 0.1 | 0.001 |
| Damaged empty dorsal shield (DEDS) # = fissures in and loss of pieces of empty dorsal shield | 0.1 ± 0.1 | 0.01 ± 0.01 | 0.44 |
| Damaged legs + damaged gnathosoma (DL + DG) # | 9.5 ± 0.7 | 6.1 ± 1.2 | 0.02 |
| Damaged legs + damaged gnathosoma + damaged shield (DL + DG + DS) # | 3.7 ± 0.4 | 1.6 ± 0.7 | 1.9e-10 |
