Fungal chitin metabolism involves diverse processes such as metabolically active cell wall maintenance, basic nutrition, and different aspects of virulence. Chitinases are enzymes belonging to the glycoside hydrolase family 18 (GH18) and 19 (GH19) and are responsible for the hydrolysis of β-1,4-linkages in chitin. This linear homopolymer of N-acetyl-β-D-glucosamine is an essential constituent o...
The Green Revolution led to an increased use of synthetic pesticides, causing environmental pollution. As alternative, biopesticides made from entomopathogenic agents such as fungi have been sought. This study aimed design and evaluate the performance a harvester machine for efficiently collecting spores Metarhizium anisopliae Beauveria bassiana grown on rice corn substrates. spore yield was es...
The Rosaceous longhorn beetle (RLHB), Osphranteria coerulescens Redtenbacher (Coleoptera: Cerambycidae) is a significant pests of fruit orchard in Iran and it is costly to control it. During an ongoing project on natural enemies of O. coerulescens in Mashhad region, North East of Iran, two isolates of entomopathogenic fungi (EPF) were isolated as natural pathogens on the larvae. The fungal isol...
Spodoptera exigua Hübner (Lepidoptera: Noctuidae) is considered a polyphagous pest distributed worldwide with wide range of hosts, and also serious plague for vegetables ornamentals. The objective this study was to explore the occurrence entomopathogenic fungi in agricultural soils from Mexico evaluate its virulence effect on life cycle S. exigua. Selected isolates (HEB1 γ01) were used perform ...
AIM Entomopathogenic fungi Metarhizium anisopliae and Beauveria bassiana had wide host range against insects and hence these are being exploited as fungal bio-pesticide on a large scale. Both fungi are proved pesticides against many crop pests and farmers are well acquainted with their use on the field. Thus, research was aimed to explore the potency of these fungal spores against larval and ad...
Insect-pathogenic fungi are important natural enemies of insect pests but their dynamics in the soils of different agroecosystems are incompletely understood. In the present study, the seasonal occurrence and species diversity of insect-associated fungi in soil were investigated by baiting soil samples with larvae of Galleria mellonella. The survey included insect-pathogenic fungi, opportunisti...
As part of a research programme designed to identify biological agents for the control of sheep scab, the pathogenicity of the fungus Metarhizium anisopliae to Psoroptes mites in the presence of sheepskin and wool was examined in the laboratory. No inhibitory effects of skin and wool were observed and high levels of infection were recorded. Subsequently the pathogenicity of formulations of both...
