An innovative and exciting development in complementary therapies is the utilization of insects as a practical and valuable way to obtain natural products. It has been discovered that a number of insect constituents serve various purposes. This research sought to evaluate the in vitro antioxidant, anti-inflammatory, anticancer and anti-Alzheimer impact of wasp venom extract and mastoparan. The present result revealed that wasp venom was much more effective than mastoparan in all the experiments done. Its antioxidant impact with IC 50 =9

Biological control is a natural method that suppresses pests and is a practical, eco-friendly, and cost-effective substitute for insecticide-based approaches. The present investigations were carried out to evaluate the potential impact of three natural enemies; Aphidius colemani Viereck, Chrysoperla carnea (Steph.) on Aphis gossypii Glover under semi-field circumstances and Beauveria bassiana Balsamo (Vuillemin) on Bemisia tabaci (Genn.) under field conditions. The study was done on sweet basil plants during the season of 2022 at Zagazig district, Sharkia Governorate, Egypt. The results revealed that the maximum parasitism percentage of A . colemani was achieved at a rate of 12 parasitoids/cage, whereas the highest percentage of emergence was recorded at a rate of three parasitoids/cage. Data also showed that the reduction percentages of cotton aphid numbers declined as the rate of C . carnea increased. Moreover, B . bassiana caused from 49.19 to 95.20% reduction in the mean numbers of B . tabaci . Therefore, A . colemani , C . carnea, and B . bassiana are being promoted for the management of the major piercing-sucking insects on sweet basil plants under Egyptian field conditions.

The isolation of a novel endophyte Pantoea ananatis , a bacterial leaf blight on mulberry leaves is the first record in Egypt. Four bacterial isolates (L1, L2, L4, and L5) were obtained from infected and healthy mulberry leaves and were identified by classical techniques which exhibited short rods and Gram-negative as well as their biochemical and physiological characteristics. Molecular identified rDNA sequences of four isolates were performed. The phylogenetic tree analysis confirmed that all isolates belong to P. ananatis . After the pathogenicity test on leaves, bacterial isolates L1 and L4 produced a typical symptom on mulberry leaves. Larvae of mulberry silkworm, Bombyx mori were orally infected with each of the four P. ananatis isolates separately to assess the silkworms' immune response. Significant variation was observed in the protein concentration and the appearance of the new hemolymph protein bands profile in the infected larvae. It is interesting to note that the immunized hemolymph of the infected larvae exhibited a marked increase in the quantity of antimicrobial peptides with molecular weights less than 30 KDa and the intensity of major proteins. However, the total protein count and humoral immune showed that the bacterial isolates L2 and L5 were more pathogenic to B. mori .

dominant species infesting all plants. The tested piercing-sucking pests were recorded 1-3 peaks, concentrating through April-May during the two tested seasons. Data showed that the increasing of B. tabaci and T. urticae populations led to a decrease in GA3, IAA and KIN contents, and an increase in ABA contents, contrariwise, the reverse direction was found with aphids and E. decipiens populations. Moreover, a negative relationship was recorded between phenoloxidase and all tested pests except whitefly was detected a positive effect. A positive relation was reported between phytochemical components and these pests except spider mite was negative. Finally, these results offer useful and appealingly data to point out herein that the infestation rate of piercing-sucking insects must refer to the resistance degree of each cultivar to help in putting the IPM management strategy in the control programs of these pests.
所有植物的主要害虫种类。所测试的刺吸式害虫在两个测试季节都出现了 1-3 个高峰，集中在 4-5 月份。数据显示，烟粉虱和荨麻虱数量的增加导致 GA3、IAA 和 KIN 含量的减少，而 ABA 含量的增加，相反，蚜虫和 E. decipiens 数量的增加则与此相反。此外，酚氧化酶与所有受测害虫之间都呈负相关，只有粉虱呈正相关。植物化学成分与这些害虫之间呈正相关，但蜘蛛螨为负相关。最后，这些结果提供了有用和有吸引力的数据，在此指出，刺吸式害虫的侵扰率必须参考每个栽培品种的抗性程度，以帮助在这些害虫的防治计划中采用 IPM 管理策略。
