The selective media most commonly used for isolating hyphomycetous species of entomopathogenic fungi from non-sterile substrates rely on N-dodecylguanidine monoacetate (dodine) as the selective fungicide. Although these media are effective for isolating many species of Metarhizium and Beauveria from soil, they are inefficient media for isolation of an important Metarhizium species, Metarhizium ...

The screening of entomopathogenic fungi, 7 isolates of Metarhizium spp., 12 isolates of Beauveria spp., and 1 isolate of Hirsutella citriformis against fruit fly was performed in Lampang Agricultural Research and Training Centre, Lampang, Thailand. The efficacy test was done by spraying suspension of 10 spores per ml of fungus on Bactrocera dorsalis in completely randomized design experiments. ...

Understanding habitat selection of fungal entomopathogens is critical to improve the efficacy, persistence and cost of these fungi as microbial insecticides. This study sought to determine the prevalence of Metarhizium and Beauveria spp. isolated from the rhizosphere of strawberry, blueberry, grape and Christmas tree crops in the Willamette Valley of Oregon. Entomopathogenic fungi were assigned...

Paraguay tea is a native crop of southern Brazil and is also socioeconomically important in Paraguay and Argentina. One of the main pests of this crop is Gyropsylla spegazziniana (Hemiptera: Psyllidae). As there are no registered insecticides for this pest in Brazil, the use of entomopathogenic fungi is an alternative method for its control. This study aimed to evaluate and characterize isolate...

The entomopathogenic fungus Beauveria bassiana was re-isolated from surface sterilized pieces of the cocoa pod outer section and peduncle, two and three months after flowers of greenhouse cocoa plants were hand-pollinated and sprayed with a 1x107 mL-1 suspension of B. bassiana conidia. The colonization frequency of B. bassiana on cocoa pods was 0.8% and 1.3% two and three months post-spraying o...

Beauveria spp. (one Beauveria sp., two B. brongniartii, and 47 B. bassiana) isolated from insects and soil from Kenya and other 16 different countries, were obtained from the CABI Bioscience Genetic Resource Collection. DNA was extracted from the 50 isolates and their genetic variability was investigated using restriction analysis of the internal-transcribed-spacer ribosomal region restriction ...

The ascomycetous genus Cordyceps accommodates endoparasitic species that attack arthropods or other fungi. Analyses of ITS nrDNA sequence data of 72 taxa from the teleomorph genera Cordyceps, Claviceps, Epichloë, and the anamorph genera Akanthomyces, Beauveria, Metarhizium, Hirsutella, Hymenostilbe, Paecilomyces, Polycephalomyces, and Tolypocladium assigned the taxa to four main evolutionary li...

beauveria spp. as entomopathogenic fungi have extremely diverse insect host ranges.here, a comparative transcript analysis of a bassiasin i (bsni), a dipeptidyl peptidase (dpp), a cytochrom p450 monooxygenase (cyp52), a mitogen activated protein kinase (mapk), and a neuronal calcium sensor 1 (ncs) in two isolates of beauveria bassiana., with low and high virulence, were carried out. for this, i...

We have analysed the mycobiota of date palm (Phoenix dactylifera, L.) leaves using several techniques. Profusely sporulating fungi (Penicillium spp. and Cladosporium spp.) developed when plating leaf fragments and leaf washings. Fusarium oxysporum, was particularly abundant in leaves infested with the red scale insect Phoenicococcus marlatti Cockerell, 1899, but an undescribed Lecanicillium cf....

Fındığın ana zararlıları yanında, genel bir zararlı olan Mayıs böceği (Melolontha spp.) fındık bahçelerinde önemli verim kayıplarına ve bitkilerin kurumasına neden olmaktadır. Karadeniz Bölgesi böceklerle mücadelede yere sahip entomopatojen mikroorganizmalar açısından oldukça zengin alandır. Ülkemizde üretim alanlarından izole edilen fungus bakteriler laboratuvar koşullarında M. melolontha’ya k...
