We used the following new range of insect species as baits for trapping entomopathogenic fungi: Plodia interpunctella, Rhyzopertha dominica, Tribolium confusum, Trogoderma granarium, Ephestia kuehniella and Tenebrio molitor, which constitute important stored product pests. Soil samples were collected from random points in olive tree orchards in Wes...

Within the context of the harmful side-effects of chemical pest control applications, the present study investigated the insecticidal effect of three commercial biopesticides, the fungal Metab (Beauveria bassiana, Metarhizium anisopliae) and Lecan (Lecanicillium lecanii), as well as raw zeolite, against Tribolium confusum Jacquelin du Val (Coleopte...

The insecticidal virulence of various entomopathogenic fungal isolates retrieved from soil samples was tested on adults of the granary weevil Sitophilus granarius (L.) (Coleoptera: Curculionidae). Bioassays were carried out in the laboratory where experimental adults were sprayed with 1 mL of conidial suspension (108 conidia/mL) from each isolate....

... Fresh conidia were harvested after 15 days by scraping the Petri dish surface with a sterile loop and placing them in a 500 mL glass beaker containing 50 mL of sterile distilled water and 0.05% Tergitol ® NP9 (Sigma-Aldrich, St. Louis, MI, USA). A magnetic stirrer was used to mix the conidial suspension for 5 min after filtering through sterile cloth layers [35]. A Neubauer hemocytometer was used for the measurement of the fungus conidia concentration (WEBER SCIENTIFIC hemocytometer for cell counting, Hamilton Township, NJ, USA). ...
... Entomopathogenic fungi are a class of microorganisms that specifically infect insects, and they regulate many pests in natural ecosystems effectively in an ecology-friendly manner [1]. The utilization of entomopathogenic fungi to manage agricultural and forestry pests has become a new trend in biological pest control [2]. ...
