An open field was chosen at El Mahala El Kobra district, El Gharbia governorate. An area of about one faddan (about 4200 m2) was cultivated by cantaloupe seed (variety, Egyptian Galia Melon). N. californicus individuals were released in each predator’s area, once in the first half plots and twice in the second half plots (at two weeks intervals), at the rate of 3, 6 and 9 individuals/2plants in the first and second three treatments of once and twice releases, respectively. A single release of N. californicus provides low reduction for the red spider mites, T. urticae. This unlikely those obtained from the double release which provides preferable results on controlling the red spider mite, T. urticae. On the other hand, one release of the predatory mite, N. californicus with the medium rate (6 predators/ 2 plants) or low rate (3 predators’ 2 plants), as well as releasing the predator two releases with the low rate resulted in low mite reduction. In conclusion, under the open field conditions, our results showed a preference for utilizing multiple releases of the predatory mite, N. californicus to regulate the populations of T. urticae. Either moderating reduction or not prevent T. urticae from exceeding the economic threshold level.
在El Gharbia省El Mahala El Kobra区选择了一块空地。种植哈密瓜种子(品种,埃及加利亚瓜)的面积约为1法丹(约4200平方米)。在每个捕食者区域释放加利福尼亚新冠小蠊个体,在前半块地释放一次,后半块地释放两次(间隔两周),在前三个处理和后三个处理中分别以3、6和9个个体/2株的速度释放。加利福尼亚新冠病毒的单一释放对红蜘蛛螨,荨麻疹螨提供了低的减少。这与双释放法的效果不太一致,双释放法对红蜘蛛螨的防治效果较好。另一方面,以中等比率(6个捕食者/ 2株植物)或低比率(3个捕食者/ 2株植物)释放一次掠食性螨,以及以低比率释放两次掠食性螨,其减少率较低。综上所述,在野外条件下,我们的研究结果表明,利用加利福尼亚新螨的多次释放来调节荨麻疹螨的种群是优先的。无论是适度减少还是不减少,都可以防止荨麻疹超过经济阈值水平。

The present study was carried out to investigate the effect of different doses of gamma irradiation (0, 50,100,500 and 1000 Gy) on the mortality percentage of both of larvae and adult stages of the red flour beetle, Tribolium castaneum Herbst. (Coleoptera- Tenebrionidae). Also, the effect of gamma irradiation on both of the Quinones secretion and the microflora associated with the pest stages was investigated. The results showed that the incremental of adult and larval mortality percentages were significant (P <0.05) affected by an increment of gamma irradiation dose. The results of Gas chromatography-mass spectrometry patterns exhibited a strong inhibitory effect of irradiation on Quinones secreted by both stages. The used doses succeed in reducing the count of microflora were associated with both larval and adult stages. This reduction reached zero for fungi and bacteria isolated from the surface at the dose 1000 Gy. Obtained data suggested that the irradiation of red flour beetles with 1000 Gy is a promising tool for the control of this destructive pest and prevent its harmful effects associated with its infestation.
本文研究了不同剂量γ辐射(0、50、100、500和1000 Gy)对红粉甲虫幼虫和成虫死亡率的影响。(鞘翅目- Tenebrionidae)。此外,还研究了γ辐照对醌类化合物分泌和与虫害阶段相关的微生物群的影响。结果表明,γ辐照剂量的增加对成虫和幼虫的死亡率有显著影响(P <0.05)。气相色谱-质谱分析结果显示辐照对两个阶段分泌的醌类化合物均有较强的抑制作用。成功减少菌群数量的剂量与幼虫期和成虫期都有关。在1000戈瑞的剂量下,从表面分离的真菌和细菌的这种减少达到零。已获得的数据表明,1000 Gy照射红粉甲虫是一种很有前途的防治方法,可以预防红粉甲虫侵染造成的有害影响。

Control management of Spodoptera littoralis (Boisd) infestation has been achieved by using chemical insecticides. However, the environment-friendly methods without unwanted side effects of these chemicals are becoming very important in modern pest management strategies. Natural products including plant ethanolic extracts and essential oils are some of the alternative approaches in pest control. The essential oils were extracted and their chemical composition was identified using a GC/MS spectrometer. Therefore, the present study was designed to evaluate the antioxidant activity of various extracts of sage and thyme plants by 2, 2-diphenyl-1-picrylhydrazil (DPPH) method. The obtained results revealed that concentrations at 25, 50, 100 and 200µg/ml of essential oils and ethanolic extract from both plants were more efficient in scavenging free radicals after 30 min when compared with butyl hydroxyl toluene(BHT) as synthetic standard. The concentrations 100 and 200µg/mL from ethanolic and essential oils were having higher activity than other extracts and standard .Furthermore, Sage and thyme extracts were investigated for their toxicity against cotton leafworm, S. littoralis in the laboratory, the percentages of cumulative mortality of larvae as well as the latent effects of the 4th instar of S. littoralis four concentrations (25, 50, 100 and 200 µg/mL) were applied. It was found that ethanolic extract of two plants was more efficient than essential oils on different stages of S. littoralis. The results showed that there were highly significant differences between all treatments and control some biological aspects.
利用化学杀虫剂对沿海夜蛾(Spodoptera littoralis, Boisd)虫害进行控制管理。然而,在现代害虫管理策略中,没有这些化学物质不良副作用的环境友好型方法变得非常重要。包括植物乙醇提取物和精油在内的天然产品是防治害虫的一些替代方法。提取精油,用GC/MS谱联用仪鉴定其化学成分。因此,本研究采用2,2 -二苯基-1-苦酰肼(DPPH)法对鼠尾草和百里香等植物提取物的抗氧化活性进行了评价。结果表明,与合成标准丁基羟基甲苯(BHT)相比,25、50、100和200µg/ml浓度的两种植物精油和乙醇提取物在30 min后清除自由基的效率更高。以100、200µg/mL乙醇提取物和精油提取物为对照品,研究了鼠尾草和百里香提取物对棉花叶虫和滨夜蛾的毒力、幼虫的累积死亡率和对4龄滨夜蛾的潜在毒力。结果表明,两种植物的乙醇提取物在不同生长阶段均比精油更有效。结果表明,各处理和对照在某些生物学方面存在极显著差异。

This study was carried out to evaluate the management of Duranta aphid Aphis durantae Theobald (Homoptera: Aphididae) which infesting duranta plantsby releasing different levels of the seven- spotted lady beetle, Coccinella septempunctata L. (Coleoptera: Coccinellidae).     This study was carried out at two locations (Governorates), The International Garden, Cairo Governorate and El-Orman Garden, Giza Governorate during successive season 2018 under glasshouse conditions.   The seven- spotted lady beetle, C. septempunctata was released for one time at early February on durantaplants at the two locations at rates of 30, 60 and 90 eggs/plant. In the first level of release (30 eggs/plant),  at  Cairo Governorate the reduction percentages in the population ofDuranta aphid, A. durantae increased gradually whereas it were 24.0, 34.4, 44.6, 57.1 and 66.6% on mid-February, first-March, mid-March, first-April and mid-April, respectively. The same trend was achieved at Giza Governorate. Also, in the second level of release (60 eggs/plant), at Cairo Governorate the reduction percentages in the population of A. durantae increased gradually whereas it were 27.1, 40.2, 50.3, 60.0 and 69.7%  on mid-February, first-March, mid-March, first-April and mid-April, respectively. The same trend was achieved at Giza Governorate. Lastly, the third level of release (90 eggs/plant), at Cairo Governorate the reduction percentages in the population of A. durantae increased gradually whereas it were 31.3, 46.0, 58.7, 68.3 and 74.1%  on mid-February, first-March, mid-March, first-April and mid-April, respectively.

In the first level of release (30 eggs/plant),  at  Cairo Governorate the reduction percentages in the population ofDuranta aphid, A. durantae increased gradually whereas it were 24.0, 34.4, 44.6, 57.1 and 66.6% on mid-February, first-March, mid-March, first-April and mid-April, respectively.

Also, in the second level of release (60 eggs/plant), at Cairo Governorate the reduction percentages in the population of A. durantae increased gradually whereas it were 27.1, 40.2, 50.3, 60.0 and 69.7%  on mid-February, first-March, mid-March, first-April and mid-April, respectively.
