موریانه ها یکی از مهمترین حشرات خسارتزا در بسیاری از کشورهای جهان از جمله ایران هستند. کاربرد حشره کش های تنظیم کننده رشد (igrs) و مواد بیولوژیک یکی از راهبردهای برنامه مدیریت تلفیقی بااین نوع حشرات است. در این بررسی اثر توام حشره کش پیری پروکسی فن با قارچ anisopliae روی موریانه amitermes vilis مورد مطالعه قرار گرفت. به منظور تعیین lc50 حشره کش های مورد آزمایش، آزمایش های زیست سنجی روی م...
Metarhizium spp. are being used as environmentally friendly alternatives to chemical insecticides, as model systems for studying insect-fungus interactions, and as a resource of genes for biotechnology. We present a comparative analysis of the genome sequences of the broad-spectrum insect pathogen Metarhizium anisopliae and the acridid-specific M. acridum. Whole-genome analyses indicate that th...
Seven termite species (Isoptera) from five families were tested for disease susceptibility against the entomopathogenic fungus Metarhizium anisopliae using a standard protocol: Mastotermes darwiniensis (Mastotermitidae), Hodotermopsis sjoestedti (termopsidae), Hodotermes mossambicus (Hodotermitidae), Kalotermes flavicollis (Kalotermitidae), Reticulitermes flavipes and Prorhinotermes canalifrons...

The efficacy of a new virulent Metarhizium anisopliae strain (SRRC 2558) obtained from Coptotermes formosanus in China was evaluated against the eastern subterranean termite, Reticulitermes flavipes and the Formosan subterranean termite, C. formosanus, in the laboratory. This new strain was compared with three other virulent M. anisopliae strains and was found to be highly infectious against te...
The cerambycid beetle Hedypathes betulinus (Klug) (Coleoptera: Cerambycidae) causes severe damage to yerba mate plants (Ilex paraguariensis (St. Hilaire) (Aquifoliales: Aquifoliaceae)), which results in large losses of production. In this study, the pathogenicity of entomopathogenic fungi of the species Beauveria bassiana (Balsamo-Crivelli) Vuillemin (Hypocreales: Cordycipitaceae), Metarhizium ...
Electrophoretic karyotypes of eight wild-type strains of Metarhizium anisopliae var. anisopliae were obtained by pulsed-field gel electrophoresis. These strains were isolated from insects of six different Brazilian states. The chromosomal DNA molecules of three strains were separated into seven bands and of five strains into eight bands. Chromosome length polymorphisms were also observed. The s...
PURPOSE To report a case of fungal keratitis caused by Metarhizium anisopliae complex. METHODS Case report. RESULTS Our patient presented with a central corneal infiltrate. Fungal culture yielded a Metarhizium species. She was started on antifungal agents with no significant improvement. A therapeutic corneal transplant was performed after perforation. At two years follow up, she was free o...
A series of laboratory bioassays were conducted for the evaluation of the insecticidal efficacy of an isolate of Metarhizium anisopliae (Metschnikoff) Sorokin (Ascomycota: Hypocreales) against larvae of the Mediterranean flour moth, Ephestia kuehniella Zeller (Lepidoptera: Pyralidae), under various temperature-relative humidity (r.h.) conditions. The fungus was applied at four doses (0, 8 × 106...
