در این تحقیق اثر همستیزی چهار جدایه از قارچ paecilomyces lilacinusو یک جدایه از قارچisaria farinosa روی مهار نماتودریشه گرهیmeloidogyne javanicaدر شرایط آزمایشگاهی و گلخانه ای روی گوجه فرنگی ارزیابی گردید. ابتدا با استفاده از ویژگی های ریخت شناسی و استفاده از آغازگر اختصاصی، نماتود ریشه گرهی و جدایه های قارچی مورد شناسایی قرار گرفتند. سپس در شرایط آزمایشگاهی توانایی جدایه های قارچی در انگلی نم...
Isaria farinosa, formerly known as Paecilomyces farinosus, have a worldwide distribution and relatively wide host range. The aim of the work is to isolate identify fungus from soil Gara mountain using molecular analysis morphological characteristics species were isolated samples collected at an insect overwintering sites in mountain, Kurdistan Region, Iraq selective medium Oat culture modified ...
A fungal pathogen that killed adult Diaphorina citri Kuwayama (Asian citrus psyllid) (Hemiptera: Psyllidae) in Florida citrus groves during the fall of 2005 was identified and characterized. Investigation of this pathogen is important because D. citri vectors citrus greening disease (Huanglongbing), which was reported in Florida in 2005. The morphological and genetic data generated herein suppo...
The hyphomycete Paecilomyces fumosoroseus (Pfr) is a geographically widespread fungus capable of infecting various insect hosts. The fungus has been used for the biological control of several important insect pests of agriculture. However knowledge of the fungus' genetic diversity and population structure is required for its sustainable use as a biological control agent. We investigated length ...
The use of biopesticides against agricultural pests is great importance for the sustainability pest management. goal present study was to determine lethal (acute) and sublethal (first male young queen emerge time, competition point, total number workers, males queens) effects four commercial [Nibortem (1.5% Lecanicillium (Verticillium) lecanii strain V1-1, Nostalgist Beauveria bassiana Bb-1), P...
Entomopathogenic fungi belonging to the genus Isaria (Hypocreales: Cordycipitaceae) are promising candidates for microbial control of insect pests. Currently, the Mexican government is developing a biological control program based on extensive application of Isaria isolates against Diaphorina citri (Hemiptera: Liviidae), a vector of citrus huanglongbing disease. Previous research identified thr...
A phylogenetic analysis of the 5.8S rDNA and internal transcribed spacer (ITS1 and ITS2) sequences from some entomogenous Paecilomyces species supports the polyphyly of the genus and showed the existence of cryptic species. In the Eurotiales, anamorphs Paecilomyces variotii and Paecilomyces leycettanus were related to the teleomorphs Talaromyces and Thermoascus. In the Hypocreales, three major ...
Nuclear-encoded small-subunit ribosomal DNA was used to examine phylogenetic relationships in Paecilomyces sensu lato. Phylogenetic analysis of the 18S nr DNA demonstrates that Paecilomyces is polyphyletic across two subclasses, Sordariomycetidae and Eurotiomycetidae. The type species, Paecilomyces variotii, and thermophilic relatives belong in the order Eurotiales (Trichocomaceae), while mesop...
In the present investigation, impact of sub lethal concentrations of entomopathogenic fungi, namely Isaria fumosorosea, Beauveria bassiana and Paecilomyces variotii, secondary metabolite on feeding, growth, fecundity and hatchability of Spodoptera litura was performed. The S. litura treated with I. fumosorosea and B. bassiana metabolites exhibited renounced food consumption. The growth rate of ...
