Genetical, Cytological & Biological Studies of OWSWF, Chrysomyabezziana (Vill.) (Diptera: Calliphoridae) Exposed to GammaRadiation: VII. Effect on Dispersal & Flight Ability Index

Abstract

This study showed that the flight ability index of the irradiated adult of
OWSWF, Chrysomya bezziana as 5 days old pupae with the doses ranged 15-90 Gy
was not significantly different from that of the control group during an experiment
carried out under laboratory conditions. But when the experiment was carried out
under field conditions, there was considerable decreases in the flight ability &
dispersal of the irradiated flies which irradiated as 5 days old pupae with the
following doses of gamma rays 45 & 75 Gy then released at the temperature of (18-
20)C, while an increases in the flight ability & dispersal were noticed if the flies
released at the temperature of (31-34)C & the flies irradiated with 60 & 90 Gy of
gamma rays as 5 days old pupae. These results indicated the importance of choosing
the correct time for releasing sterile insect if an programm for eradicating this pest
will be used in near future.
