Reproduction parameters of Glossina palpalis gambiensis females mated with males irradiated as pupae with fractionated (10 + 100 Gy and 50 + 60 Gy) and single doses (110 Gy), separated with 1-, 2- and 3-day intervals (D1, D2, D3). Mature female days were calculated for each treatment by adding the number of flies alive each day, starting on D18 after emergence (age of maturity) until the end of the experiment on D60.
| Treatment radiation dose (Gy, days) | Parental pupae emergence (%) | Mature female days* | No. of aborted eggs and instar larvae |
No. of pupae produced | Mean ± SD fecundity | Mean ± SD induced sterility (%) | Produced pupae emergence/females (%) | Age at emergence (days) | |||
