ONDRÁČKOVÁ E., SEIDENGLANZ M., ŠAFÁŘ J. (2019): Effect of seventeen pesticides on mycelial growth of Akanthomyces, Beauveria, Cordyceps and Purpureocillium strains.

abstract
The effect of fungicides, herbicides and insecticides on mycelial growth of entomopathogenic fungi Akanthomyces muscarius, Beauveria bassiana, Cordyceps fumosorosea and Purpureocillium lilacinum were tested under laboratory conditions. Fungicides containing the active ingredients carboxin & thiram, dimethomorph & mancozeb, mancozeb & metalaxyl-M, boscalid & pyraclostrobin, mancozeb, metalaxyl-M & fludioxonil and herbicides with active ingredients pendimethalin, pethoxamid, chlorotoluron and pendimethalin & imazamox statistically significantly inhibited the mycelial growth of all tested fungi (20.4–100% and 14.9–100% inhibition). Insecticides did not significantly inhibit the mycelial growth of Akanthomyces and Purpureocillium strains but active ingredients tau-fluvalinate, pirimicarb and acetamiprid inhibited the mycelial growth of Beauveria strains (22.6–30% inhibition). The mycelial growth of Cordyceps strains was faster in the presence of insecticides than in controls.

abstract
Leptoglossus occidentalis, an insect species native to North America, is a pest of conifer seed orchards in its natural distribution area. Recently, it was accidentally introduced into Europe where its populations have been expanding throughout the continent. In this study we evaluated the pathogenicity of Beauveria bassiana, Isaria fumosorosea, and Metarhizium anisopliae to this pest under laboratory and outdoor conditions. Pathogenicity varied depending upon isolates, exposure methods and location of bioassay. In the laboratory, LC values were highest for I. fumosorosea and lowest for 50 M. anisopliae, and an indirect exposure was less effective than a direct one. In outdoor experiments the overall mortality was in all isolates significantly lower than mortality in the laboratory, and inter-specific variability in pathogenicity was not as prominent outdoors as in the laboratory. The results of this bioassay showed that I. fumosorosea has the potential as a microbial control agent of L. occidentalis.
