The greater wax moth Galleria mellonella is responsible for serious economic losses to bee keepers in developing countries. Larvae feed on the wax comb in weak colonies or during the storage of wax combs in winter. The objective of the current study was to assess the effect of the Cytokinin plant growth regulator, Benzyladenine (6-BA), on the most important parameters of adult performance and reproductive potential of G. mellonella. The 3rd instar larvae were force-fed on an artificial diet supplemented with six concentrations, viz., 100, 10.0, 1.0, 0.1, 0.01 & 0.001ppm of 6-BA. No adult moths could metamorphose at the higher three concentrations because of larval and pupal deaths. The most important results could be summarized as follows. The adult emergence was blocked by 6-BA, in a dose-dependent course. Also, the tested compound displayed strong adulticidal activity, since adult mortality increased in a dose-dependent course. The total adult longevity of moths was significantly prolonged.All longevity compartments were remarkably prolonged. On the other hand, 6-BA failed to affect adult morphogenesis. The oviposition efficiency was deleteriously prohibited. Also, 6-BA exhibited a tremendous inhibitory effect on the female fecundity and reducing effect onfertility. The embryonic development in eggs laid by treated adult females was severely retarded, since the incubation period of these eggs was remarkably prolonged.

Background: Chronic kidney disease (CKD) leads to a progressive decline in kidney function that eventually progresses to end-stage renal disease. It is critical to identify people at risk for renal disease and to intervene early to avoid kidney damage. Tryptophan hydroxylase (TPH-1) is an accurate biomarker for CKD early stage. The loss of tryptophan hydroxylase contributes to kidney injury. N-acetylcysteine, glycine, and tryptophan can arrest renal fibrosis development and progression through the anti-fibrotic effect of tryptophan hydroxylase and the protective effect of N-acetylcysteine. Objectives: This study aims to assess the metabolic effect of N-acetyl-l-cysteine on kidney function as an EGFR inhibitor and its effect on AAs depletion. In addition, to evaluate the effect of glycine and tryptophan on kidney injury and renal fibrosis progression. Results: Eight weeks of administration of pemetrexed led to a significant increase in serum, urea, creatinine, and uric acid. Administration of N-acetylcysteine (NAC with pemetrexed) resulted in a significant decrease in biochemical kidney function. Also, glycine and tryptophan directly affect renal function; increased expression of tryptophan hydroxylase with decrease expression of EGFR and transforming growth β (TGF-β), compared to N-acetylcysteine group. Conclusion: N-acetylcysteine, glycine, and tryptophan can halt the depletion of AAs in the presence of urea and EGFR. Glycine and tryptophan both have a direct effect on renal function due to their uric acid-lowering properties.

In order to evaluate physiological and biochemical changes of wheat plants (Triticum aestivum L.) under the stress of four herbicides namely, (pinoxaden, tribenuron-methy, pyroxsulam and clodinafop-propargyl) at recommended dose on three wheat cultivars (Saka 95, Giza 171 and Shandweel 1). In a totally randomized method, an experiment was performed in El-Sharkia Governorate, Egypt. During 2020 season. The analysis of variance showed that the content of the main pigments of leaf (chlorophyll a, chlorophyll b and caroteniod), activity of catalase, peroxidase, oxidase enzymes and ascorbic acids. Data showed that the herbicide pinoxaden was the highest toxicity while tribenuron-methy was the lowest one on the three cultivars of wheat in chlorophyll content. Chlorophyll a, the reduction percentages were17 .2, 16.8 and 13.6 % in Giza 171, Shandweel 1 and Saka 95, respectively compared with control. The reduction percentages in chlorophyll b were 14.8, 14.2 and 11.0 % in Saka 95, Giza 171 and Shandweel 1 , respectively compared with control. The opposite picture in carotenoid the reductions were 18.8, 15.3, and 9.7 % in Giza171, Saka 95 and Shandweel 1 compared with control. On the other hand, the four herbicides led to a significant decrease in the activity of wheat antioxidant enzymes compared with control. Results showed that the oxidase and peroxidase enzymes were high sensitivity to all treatments compared with control, but ascorbic acid and catalase enzymes appear low sensitivity on all cultivars of wheat. These results showed that all used herbicides reduce plant tolerance from damage and enzymes activities, therefore it can be used as an index in physiological research.

The current study was conducted to investigate the biological activities of the two strains of Bacillus thuringiensis (Bacillus thuringiensis var. Kurstaki 1(Bt K1) and Bacillus thuringiensis var. Kurstaki 2 (Bt K2)) against the newly hatched (neonate) larvae of the pink bollworm, Pectinophera gossypiella. The two strains exhibited their toxicity against the treated larvae. Also, the lethal effect was extended in the resulted stages, pupae and adults. Based on LC50 for total mortality, Bt K1 was more potent than Bt K2 where LC50 was 2.21x1010 and 3.11x1010, respectively. However, the two strains were revealed a reduction of pupation and adult emergence %. Irrespective of the strain, Bt significantly decreased larval duration and significantly increased pupal duration. No effect was recorded on morphogenesis. In the present study,it was broadly that Bacillus thuringiensis showed its ability in the control of Pectinophora gossypiella.
本试验研究了苏云金芽孢杆菌(Bacillus thuringiensis var. Kurstaki 1(Bt K1))和苏云金芽孢杆菌(Bacillus thuringiensis var. Kurstaki 2 (Bt K2))两株菌株对粉红棉铃虫Pectinophera gossypiella新孵化幼虫的生物活性。这两种菌株对处理后的幼虫均表现出毒性。毒力在成虫期、蛹期和成虫期均有延长。根据总死亡率LC50, Bt K1比Bt K2更有效，LC50分别为2.21x1010和3.11x1010。但两菌株的化蛹率和成虫羽化率均降低。无论哪种菌株，Bt均显著降低幼虫持续时间，显著增加蛹持续时间。对形态发生无影响。在本研究中，苏云金芽孢杆菌对果胶蚜的控制能力得到了广泛的认可。
