Efficacy of Various Entomopathogenic Fungi Strains as Biocontrol Agents for Control of Callosobruchus maculatus (Fabricius) (Coleoptera: Bruchidae)

Journal of Agricultural Sciences, 2021
Cowpea seed beetle, Callosobruchus maculatus (F.) (Coleoptera: Bruchidae), is considered an important bruchid pest in cowpea seed storages. The used pesticides against this pest have caused the occurrence of resistant populations and direct toxicity to ...

Paecilosetin Derivatives as Potent Antimicrobial Agents from Isaria farinosa

Journal of Natural Products, 2020
Fifty-seven entomopathogenic microorganisms were screened against human pathogens and subjected to mass spectrometry molecular networking based dereplication. Isaria farinosa BSNB-1250, shown to produce potentially novel biologically active metabolites, was grown on a large scale on potato dextrose agar, and paecilosetin (1) and five new analogues (2-6)

Susceptibility of Myzus persicae, Brevicoryne brassicae and Nasonovia ribisnigri to fungal biopesticides in laboratory and field experiments [PDF]

, 2020
The aim of this study was to evaluate the potential of entomopathogenic fungi (EPF) for the control of aphid pests of field vegetable crops. Four biopesticides based on the EPF Beauveria bassiana (Botanigard ES and Naturalis L), Cordyceps fumosorosea s.l.

High concentrations of biological aerosol particles and ice nuclei during and after rain [PDF]

Atmospheric Chemistry and Physics, 2013
Bioaerosols are relevant for public health and may play an important role in the climate system, but their atmospheric abundance, properties, and sources are not well understood.

A standardised bioassay method using a bench‐top spray tower to evaluate entomopathogenic fungi for control of the greenhouse whitefly, Trialeurodes vaporariorum

Pest Management Science, Volume 76, Issue 7, Page 2513-2524, July 2020., 2020
Entomopathogenic fungi (EPF) are commercially developed as microbial bioprotectants for whitefly control. Here, we describe the calibration and use of a pressurised spray tower to deliver a standardised laboratory protocol to allow 14 day assessments of EPF activity; the method was validated using 18 EPF from four genera in tests against greenhouse ...

Ice nucleation by water-soluble macromolecules [PDF]

Atmospheric Chemistry and Physics, 2015
Cloud glaciation is critically important for the global radiation budget (albedo) and for initiation of precipitation. But the freezing of pure water droplets requires cooling to temperatures as low as 235 K.

Cycloaspeptides F and G, Cyclic Pentapeptides from a Cordyceps-Colonizing Isolate of Isaria farinosa [PDF]

Journal of Natural Products, 2009
Cycloaspeptides F (1) and G (2), two new cyclic pentapeptides, and the known cycloaspeptides A (3), C (4), and bisdethiodi(methylthio)hyalodendrin (5) have been isolated from the crude extract of the fungus Isaria farinosa that colonizes Cordyceps sinensis. The structures of 1 and 2 were elucidated primarily by NMR and MS methods.

The microbiology of Lascaux Cave [PDF]

, 2010
Lascaux Cave (Montignac, France) contains paintings from the Upper Paleolithic period. Shortly after its discovery in 1940, the cave was seriously disturbed by major destructive interventions. In 1963, the cave was closed due to algal growth on the walls.

The antitumor and antioxidative activities of polysaccharides isolated from Isaria farinosa B05

Microbiological Research, 2008
The water-soluble intra-polysaccharides WIPS1 and water-soluble extra-polysaccharides WEPS1 were isolated from Isaria farinosa B05 through ethanol precipitation and gel permeation chromatography (GPC). Their characteristics were determined by chemical analysis, gas chromatography, GPC and IR spectroscopy.
