Fifty fungal isolates (filamentous and uni cellular) were screened for their ability to reduce sodium selenite (Na 2 Seo 3 ). Out of those, twenty eight isolates displayed positive results therefore they were screened for their ability to tolerate higher concentrations of sodium selenite for different incubation periods. The most active three isolates were characterized morphologically and physiologically. They were identified as Fusarium oxysporum, Rhodotorula mucilaginosa and Cryptococcus albidus based on 18S RNA encoding gene. The selenium reduction power by Fusarium oxysporum decreased by increasing the selenite concentration, where it reached the maximum value 96.6% of 1mM concentration of sodium selenite with the net dry weight 7.7 mg/ml. However, the reduction power of Rhodotorula mucilaginosa and Cryptococcus albidus reached the maximum value 99 and 98.8% of 5 and 7mM of sodium selenite with the net dry weight 7.2 and 6.6 mg/ml respectively. It was found that F. oxysporum reduced selenite extra cellular while both R. mucilaginosa and C. albidus reduced it intra cellular. The biosynthesized selenium particles
筛选了50株真菌分离株(丝状和单细胞)对亚硒酸钠(Na 2 Seo 3)的还原能力。在这些菌株中，有28株显示出阳性结果，因此对它们进行了筛选，以确定它们在不同潜伏期内耐受较高浓度亚硒酸钠的能力。对活性最强的3株菌株进行了形态和生理特征分析。根据18S RNA编码基因鉴定为尖孢镰刀菌、粘胶红酵母和白隐球菌。随着亚硒酸钠浓度的增加，尖孢镰刀菌对硒的还原能力降低，在亚硒酸钠浓度为1mM时，其还原能力达到最大值96.6%，净干重为7.7 mg/ml。而在净干重分别为7.2 mg/ml和6.6 mg/ml的亚硒酸钠浓度为5和7mM时，粘红酵母和隐球菌的还原力最大，分别为99%和98.8%。结果表明，尖孢镰刀菌在胞外还原亚硒酸盐，而黏液镰刀菌和绿毛镰刀菌在胞内还原亚硒酸盐。生物合成的硒颗粒

Soil microorganisms can improve plant health by allowing broad-spectrum resistance of the treated plants against insect herbivores. The present study was conducted to evaluate the effect of four different types of biofertilizers; Azotobacter sp. , Azospirillum sp. , Bacillus megatherium, and Vasicular arbuscular endomycorrhizae (VAM) on the incidence and abundance of insect pests of the eggplant, Solanum melongena (L) during autumn season. The studied pests were; Bemisia tabaci, Empoasca sp. , thrips tabaci , two species of aphids, Aphis gossypii (Glover) and Myzus persicae
