ارزیابی ایزوله های قارچ بیماریزای حشرات Paecilomyces fumosoroseus (Deutromycotina: Hyphomycetes) برای کنترل سفید بالک پنبه Bemisia tabaci (Hemiptera: Aleyrodidae)
سفیدبالک پنبه یکی از آفات مهم در اقلیم‌های مختلف کشاورزی از جمله مناطق گرمسیری و نیمه گرمسیری و همچنین محصولات گلخانه‌ایی می‌باشد.به‌منظور به‌دست آوردن یک عامل قارچی مؤثر برای کنترل این سفیدبالک تعداد ده ایزوله از قارچ P. fumosoroseus در مقابل آفت مذکور مورد ارزیابی قرار گرفت. قدرت جوانه‌زنی کنیدی‌های قارچ با کشت آن‌ها در محیط کشت PDA بعد از 24 ساعت در دمای 1±24 درجه‌ی‌سانتی‌گراد اندازه‌گیری شد...
متن کاملIsolation and characterization of microsatellite loci from the entomopathogenic hyphomycete, Paecilomyces fumosoroseus
Nine microsatellite markers were isolated from the entomopathogenic haploid fungus Paecilomyces fumosoroseus. Genetic diversity was assessed in 26 P. fumosoroseus isolates originated from the whitefly Bemisia tabaci collected in various geoclimatic areas. Eight loci were polymorphic with an observed number of alleles ranging from two to six. The loci differentiated some isolates and group of is...
متن کاملAerial treatment of the Australian plague locust, Chortoicetes terminifera (Orthoptera: Acrididae) with Metarhizium anisopliae (Deuteromycotina: Hyphomycetes).
Between October 1999 and April 2000, nearly 4000 ha of nymphal bands and adult swarms of Chortoicetes terminifera (Walker) were aerially treated using a ULV oil formulation of strain FI-985 of Metarhizium anisopliae var. acridum. During the mild weather (maxima 22-30 degrees C) of spring (October), there was little change in nymphal bands during the first week but at all doses between 25-100 g ...
متن کاملHydrophobic and electrostatic cell surface properties of blastospores of the entomopathogenic fungus Paecilomyces fumosoroseus.
The physicochemical surface properties of blastospores of the entomopathogenic fungus Paecilomyces fumosoroseus were examined. Contact angle measurements were performed on microbial lawns composed of blastospores of P. fumosoroseus to quantify their cell surface energy components. In addition, suspensions of the blastospores were characterized with the microbial adhesion to solvents assay. Zeta...
متن کاملVirulence of Entomopathogenic Fungi Metarhizium anisopliae and Paecilomyces fumosoroseus for the Microbial Control of Spodoptera exigua
The beet armyworm Spodoptera exigua (Lepidoptera: Noctuidae) is difficult to control using chemical insecticides because of the development of insecticide resistance. Several pest control agents are used to control the beet armyworm. Entomopathogenic fungi are one of the candidates for eco-friendly pest control instead of chemical control agents. In this study, among various entomopathogenic fu...
