Table 2. Size of the right and left glands (µm2) and the size difference between them (µm2) in flies kept unfed (with sugar water available) and flies fed singly or in groups (20 individuals) on a naive hamster.
Experimental group | Sample size (n) | Right gland size (µm2) | Left gland size (µm2) | Size difference between glands (µm2) |
Unfed flies | 20 | 29.9±7.8 | 26.3±7.2 | 3.6±2.5 |
Single blood-fed fly | 18 | 37.6±6.2 | 22.8±5.3 | 14.8±4.9 |
Group blood-fed flies | 18 | 36.9±9.6 | 26.7±9.2 | 10.2±6.1 |
All data are means±SD (sample size).
