Table 2. Sterilizing capacity of irradiated and incompatible males.
Crosses | 1 day-old | 5 day-old | 10 day-old | ||||
---|---|---|---|---|---|---|---|
(males × females) | N. eggs | Hatching rate (95% CI) | N. eggs | Hatching rate (95% CI) | N. eggs | Hatching rate 95% CI | |
Sterile | LRi × LR | 1772 | 0.061 (0.051–0.073) | 2600 | 0.046 (0.038–0.055) | 3243 | 0.081 (0.072–0.091) |
ARwPLR × LR | 1271 | 0 (-) | 3799 | 0 (-) | 2693 | 0 (-) | |
Fertile | LR × LR | 2365 | 0.770 (0.752–0.787) | 2972 | 0.561 (0.543–0.579) | 2606 | 0.833 (0.818–0.847) |
Males (N = 20) were allowed to mate with females (N = 20) for 24 h. Three replications were performed for each type of cross and two series of eggs were collected. LR = wild type, LRi = wild type irradiated, ARwPLR = incompatible. The hatching rates are indicated with their 95% confidence intervals (95% CI). Note that the two batches were pooled as there was no significant difference (see text).
