The occurrence of entomopathogenic fungi isolated from stored grain insect pests sampled from various geographical regions of Punjab, Pakistan, was investigated. In total, 25,720 insects from six different species were evaluated, and 195 isolates from 24 different fungal species were recovered. These included the Ascomycetes Beauveria bassiana sensu lato (Balsamo) Vuillemin (Hypocreales: Clavic...

INTRODUCTION The use of entomopathogenic fungi to control disease vectors has become relevant because traditional chemical control methods have caused damage to the environment and led to the development of resistance among vectors. Thus, this study assessed the pathogenicity of entomopathogenic fungi in Triatoma dimidiata. METHODS Preparations of 108 conidia/ml of Gliocladium virens, Talarom...

The entomopathogenic fungi are organisms that evolved to exploit insects. They comprise a wide range of morphologically, phylogenetically, and ecologically diverse fungal species. Entomopathogenic fungi can be found distributed among five of the eight fungal phyla. Entomopathogens are also present among the ecologically similar but phylogenetically distinct Oomycota or water molds, which belong...

Background The entomopathogenic fungi are important microbial agents for their efficient performance as microbial biopesticides in pest control. The development of commercial products formulated with entomopathogenic fungi is in a promising market for biopesticides. However, the fungi can lose their viability when exposed to unfavorable conditions of temperature, humidity and ultraviolet radiat...

Entomopathogenic fungi are naturally occurring pathogens of some insects that produce enzymes capable of penetrating into an insect’s cuticle. Chitinases are thought to be responsible for entomopathogenic fungi’s ability to degrade cuticle. Primers were designed for the chi3 gene which encodes a chitinase CHIT30, from the mRNA transcript present in Metarhizium anisopliae. These primers were una...

Examining dead insects from different locations in Mazandaran, Gilan and TehranProvinces, specimens with fungal outgrowth were selected for further investigations. After isolation and purification of fungi they were identified as follows:Beauveria brongniartii (Sacc.) Petch*On Coccinella septempunctata, Tehran Prov., Varamin, Ghara-Aghaj mountains, M.H. Ghassemi (IRAN 1025 C). Paecilomyces tenu...

Hemiberlesia pitysophila Takagi is an extremely harmful exotic insect in forest to Pinus species, including Pinus massoniana. Using both morphological taxonomy and molecular phylogenetics, we identified 15 strains of entomogenous fungi, which belong to 9 genera with high diversities. Surprisingly, we found that five strains that were classified as species of Pestalotiopsis, which has been consi...

Entomopathogenic fungi are a special group of soil-dwelling microorganisms that infects and kills insects other arthropods through cuticle penetration. They currently used as biocontrol agents against insect plant pests play vital role in their management. Regardless entomopathogenic on the agriculture market, full potential has not yet been utterly explored. Up to date substantial research cov...

the entomopathogenic-fungus-life cycle is associated with the synthesis and secretion of a number of toxic metabolites, including extracellular enzymes and the low-molecular weight compound (toxin). the potential for a successful pathogen relies on the ability to overcome the various host-defence systems. interaction between the fungus, tolypocla-dium (deuteromycetes), its secondary metabolite,...
