Abstract : |
In the present research radiation sterilization dose of Bactrocera cucurbitae (Coquillett) was determined. Egg viability was reduced to 0.93% at a dose of 30 Gy. Cent percent sterility in both males and females was achieved at 40 Gy. Mating competitiveness and sexual or total competitiveness of males were measured quantitatively from direct observations and ratio test methods, respectively. In direct observation method the males treated up to 30 Gy were almost equally competitive as untreated males. In ratio test method the total competitiveness values (C) of treated males were estimated 0.73-0.91 at three different ratios from 1:1:1 to 3:1:1 under laboratory condition., In the present research radiation sterilization dose of Bactrocera cucurbitae (Coquillett) was determined.
