“…The highest reduction in the number of eggs laid was at high doses of (50 Gy). These results are also true with (Zahran et al,2013), where they observed that no eggs were deposited when Bactrocera zonata irradiated with 50, 70, or 90 Gy received from a Cesium cell-137. Also, (Draz et al 2016) demonstrated that a dose of 70 Gy for males and 50 Gy for females or both sexes were sufficient to decrease the daily egg-laying of mated females when Bactrocera zonata were irradiated with cobalt-60.…”

“…Complete sterility (100%) occurred at 50 Gy when un-irradiated females crossed with irradiated males. Where (Zahran and Hegazy et al, 2013) found that doses ranging from 8-10 K-rad (=100 Gy) induced high levels of sterility. Puanmanee (2010) also reported an increase in the sterility of Bactrocera correcta when treated males crossed with untreated females as the gamma dosage increased.…”

Five days old B. zonata pupae were subjected to gamma irradiation at doses of 25, 30, 35 and 50 Gray (Gy), from a Cesium cell-137. The resulting males were crossed with untreated females. The mean total number of eggs laid by the female (fecundity) is significantly decreased (P < 0.05) with the dose increase. The viability (hatching percent) of deposited eggs at all three doses showed a significant decrease (P < 0.05). Laid eggs by females mated with males resulted from pupae treated with gamma radiation with doses 25,30,35 and 50 Gy were processed for histological studies. First cleavage nuclei were observed about 2 hours pop and the blastoderm formation occur about 4 hours pop in control. At 8 hours pop, the blastoderm thickness forming the germ band. In about 24 hours pop brain appeared. The germ band Segmentation and formation of different organs started about 36hrs POP. Doses of 25 and 30 caused a failure of cleavage nuclei to migrate toward the periphery to form the blastoderm. While other embryos were blocked at germ band formation. In doses of 35 and 50 Gy, massive cellular and tissue damage to the embryos was reported.

“…Many authors had studied the effect of gamma radiation on the sensilla of different insects. Haiba [16] on the legs of potato tuber moth, Phthorimae operculellaea; El-Akhdar [17] on wings and mouth parts of the Mediterranean fruit y, Ceratitis capitata; Hazaa [18] on antennal sensilla in the male moth of the cotton leaf worm, Spodoptera littoralis and Zahran [19] on ovipositor sensilla of the peach fruit y, Bactrocera zonata. These authors found many of malformations and changes in the shape of the sense organs as a result of the effect of gamma radiation.…”

Morphology of the Fall Armyworm (FAW) Spodoptera frugiperda adult antenna was photographed by Scanning Electron Microscope (SEM). The type of the antenna is filiform, and consists of three main segments: the scape, pedicel and flagellum. Scanning of antennae revealed the presence of eight types of sensilla in male and seven in female which are Sensillum Squamiformia, Scales, Sensillum Styloconica, Sensillum Trichodea, Sensillum Chaetica lateral and central, Sensillum Coeloconica, Sensillum Auricillica and Sensillum Basiconica which are distributed among the antennal segments. These types of sensilla found in both sexes except Sensillum Styloconica. The effect of four doses of gamma radiation (50, 100, 150 and 200 Gy) on the antennal sensilla were studied. These studies revealed that these higher doses in both sexes have certain malformation features in the sensilla. The magnitude of these malformations was dose dependent as they increased by increment of the doses applied. These malformations in the sensilla and its role in courtship and mating inhibition were discussed.
