Medflies can infest over 300 species of fruit plants, adapt to a variety of climate zones and have a high invasive potential. Medfly can target economically valuable fruit, resulting in significant economic losses estimated to be in the billions of dollars per year. This study aimed to investigate the effect of X-ray irradiation on the female ovary of Ceratitis capitata (resulting from irradiated pupae) in comparison to a normal female ovary of the same age. The structure of normal and treated female ovaries of Ceratitis capitata was studied using light and transmission electron microscopy. The female reproductive system of Ceratitis capitata is composed of paired lateral ovaries. Each ovary consists of polytrophic meroistic ovarioles formed by a terminal filament, a germarium and a vitellarium. The female ovaries were greatly affected by X-ray irradiation because of the appearance of abnormal shape and size of egg chambers, degeneration of nurse cells and their nucleus, the nucleus of follicular epithelium appear devoid of chromatin materials, presence of lysosomes and myeloid bodies, the oocytes appear devoid of yolk granules and its nucleus. The results of this study show that X-ray radiation technology has a clear effect on C. capitata and could be considered an effective and safe method to control medflies populations.","PeriodicalId":11424,"journal":{"name":"Egyptian Academic Journal of Biological Sciences.

Therefore, the present studies were carried out on 5 medicinal and aromatic crops at Assiut Governorate during two consecutive growing seasons of 2011-2013 at Shotb district and Abnoub district. Various biological parameters of Aphis craccivora Koch were studied on coriander and henna host plants, in addition to bean, as a primer host. Other host plants showed high mortality rates for aphids when it was reared on. As for the survival percentage of A. craccivora on the three cultivars, the highest percentage was recorded on henna plants, followed by coriander and bean plants. A. craccivora adult’s longevity extended when reared on henna host plants, adults who reared on coriander had the highest number of offspring, followed by henna then bean host plants. The survival rates of total nymphal stages were the highest when reared on the henna host plant, while the lowest was recorded on the bean. Different host plants in the 2nd generation seemed to be less effective on the pest’s life table parameters. Superoxide dismutase activity (SOD) activity, Catalase (CAT) activity, Protein, lipids and carbohydrates content were significantly affected by different host plants. As for the digestive enzymes, the activities of α-amylase and lipase enzymes were not affected with different host plants.","PeriodicalId":11424,"journal":{"name":"Egyptian Academic Journal of Biological Sciences.

Although EPN research studies in Egypt aim to the identification and usage of highly potent and effective indigenous strains against economically significant insect pests, no companies have yet been established for the development and sale of these plant protection products except for small special units affiliated with some research institutes and universities. On increasing demand for non-chemical forms of pest control and the high price product of EPNs, this research assessed the financial feasibility of Galleria mellonella farming for in vivo production of EPNs at small and medium scales. The main finding indicated that the cost production of indigenous EPNs (one Sachest containing 5 x 10 7 IJs) is 200 LE which is considered a low-price product in comparison to the price of products which is variable from about US$ 15 to US$ 160 per sales unit.

The present study aimed at investigating the effect of gamma radiation on the reproductive potential and embryonic lethality of C. albiceps. Results showed that the number of eggs laid by C. albiceps females resulted from pupae irradiated with different doses of gamma radiation decreased as the dose increased. Also, the non-hatching eggs %was found to be dose-dependent i.e., increased as the dose of the gamma irradiation used increased.The highest reduction in the number of eggs occurred at high doses (10 and 15 Gy) when irradiated females were crossed with non-irradiated males. Non-hatching egg % increased to record 76.6 and 66.8 at 15 and 10 Gy when irradiated females crossed with irradiated males. Gamma radiation resulted in a progressive increase in the sterility % of C. albiceps females as compared with the untreated group. Complete sterility (100.0%) was attained by 20 Gy for all groups. The sterility index was recorded at 96.3% when irradiated females crossed with non-irradiated males.In addition, gamma radiation-induced a progressive increase in egg lethality giving an estimated LD 50 value of 9.3598 Gy when non-irradiated females mated with irradiated males, compared with 10.6257 Gy for egg-lethality laid by irradiated females mated with non-irradiated males. However, the LD 50 value was 3.603 Gy when both males and females were irradiated, respectively. Generally, C. albiceps females were more radiosensitive than their male counterparts.","PeriodicalId":11424,"journal":{"name":"Egyptian Academic Journal of Biological Sciences.
