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.

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.

Pathogenic activity of Isaria spp. for control of Dactylopius opuntiae (Hemiptera: Dactylopiideae) and the effects of selected insecticides [PDF]
, 2019 We analyzed the activity of the entomopathogenic fungi Isaria farinosa, I. fumosorosea and I. javanica against the cochineal Dactylopius opuntiae, as well as the effects of the insecticides clorpirifos, acetamiprid, thiamethoxam and lambda-cyhalothrin on

Integrated Management of European Cherry Fruit Fly Rhagoletis cerasi (L.): Situation in Switzerland and Europe [PDF]
, 2012 : The European cherry fruit fly, Rhagoletis cerasi (L.) (Diptera: Tephritidae), is a highly destructive pest. The low tolerance for damaged fruit requires preventive insecticide treatments for a marketable crop.

Insect Science, Volume 23, Issue 6, Page 854-868, December 2016., 2016 Abstract Low impact alternatives to synthetic insecticides for the control of apple sawfly (Hoplocampa testudinea Klug) are scarce encumbering pest management in organic apple orchards. We investigated the soil persistence and field efficacy of the entomopathogenic fungus Beauveria bassiana (Balsamo) Vuillemin (BotaniGard) against apple sawfly under ...

Risks of Mycotoxins from Mycoinsecticides to Humans
BioMed Research International, Volume 2016, Issue 1, 2016., 2016 There are more than thirty mycotoxins produced by fungal entomopathogens. Totally, they belong to two classes, NRP and PK mycotoxins. Most of mycotoxins have not been paid sufficient attention yet. Generally, mycotoxins do not exist in mycoinsecticide and might not be released to environments unless entomogenous fungus proliferates and produces ...
