The Cordyceps genus includes many species of fungi, most of which are endoparasitoids on arthropods.The distribution of these fungi is cosmopolitan, but many occur in regions such as Asia with a hot, humid climate. These pathogens of insect pests are promising candidates for use as biological control factors. Entomopathogenic fungi including the famous Cordyceps sinensis produce bioactive compo...

Akanthomyces species have only been reported from Guizhou and Qinghai Province, with few reports other regions in China. In this research, the diversity of Jinyun Mountains, Chongqing was investigated. Fourteen infected spider specimens were collected two new ( A. bashanensis beibeiensis ) a known tiankengensis established described according to multi-locus phylogenetic analysis morphological c...

The natural occurrence of entomophthoralean fungi pathogenic towards aphids on cereal and potato crops was investigated in the years 2009, 2010, and 2011. Infected aphids were sampled in three bioclimatic zones in Tunisia (Beja, Cap bon, and Kairouan) and fungal species were determined based on morphological characters such as shape, size, and number of nuclei in the primary conidia. Polymerase...

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 susceptibility of Agrilus planipennis Fairmaire (Coleoptera: Buprestidae) to selected strains of the entomopathogenic fungi Beauveria bassiana (Balsamo) Vuillemin and Metarhizium anisopliae (Metschnikoff) Sorokin was evaluated through bioassays with direct immersion or foliar exposureunder laboratoryconditions.Results showed thatA.planipennisadultswere susceptible toB. bassiana andM. anisop...

Entomopathogenic fungi seem to be interesting as a source of biologically active compounds such as an insecticides1) and immunosuppressants2,3), because all insect orders are susceptible to fungal diseases. With the goal of finding novel bioactive compounds from fungi, we investigated metabolite diversity using an HPLC screening program. During the screening process, we isolated two novel metab...

This study investigates the mechanisms as well as strategies for purification and characterization of potential enzymes involved in pathogenesis of entomopathogenic fungi. The test strain of Verticillium lecanii that was screened, during the present investigation, proved to be an efficient producer of protein and polysaccharide degrading enzymes (amylase, protease, and lipase), hence indicating...
