Indices enabling the measurement of defensive investment by the hives
| Hive | Gm | Gsd | NPm | NPsd | SC |
|---|---|---|---|---|---|
| 1 | 1a | 0.96 | 10e | 6.1 | 20,000 |
| 2 | 9b | 3.51 | 17e | 24.3 | 30,000 |
| 3 | 8b | 2.61 | 138f | 150.5 | 40,000 |
| 4 | 12c | 3.45 | 124f | 93.2 | 40,000 |
| 5 | 23d | 3.91 | 164f | 250.4 | 40,000 |
Gm, mean number of guards at the entrance of nest; Gsd, standard deviations of this mean; NPm, mean number of total stings for each experiment; NPsd, standard deviation of this mean; SC, size of the colony. Means for the same characteristics followed by different letters are significantly different (P < 0.05, Newman-Keuls test).
