Three DNA regions (ITS 1, LSU rRNA and GPD) of isolates from the insectpathogenic fungus genus Entomophthora originating from different fly (Diptera) and aphid (Hemiptera) host taxa were sequenced. The results documented a large genetic diversity among the fly-pathogenic Entomophthora and only minor differences among aphid-pathogenic Entomophthora. The evolutionary time of divergence of the fly...

Entomophthora thripidum is an obligate biotrophic insect pathogenic fungus that grows as protoplasts within the hemocoel of thrips. Prior to penetration through the insect cuticle and spore formation at the insect surface the protoplasts switch to hyphal growth. In vitro, the differentiation to hyphal growth was a prerequisite for the subsequent formation of infectious spores and was detected 1...

A universal method for the complete assessment of atmospheric fungal spores does not exist, which is continuous, volumetric and non-selective, and offers at the same time reliable identification of the collected spores. To perform a survey of airborne fungal spores, a choice has to be made between a viable and non-viable method. For the study carried out in Leiden, the non-viable, continuous vo...

Among 170 insects infected by fungal pathogens, obtained during 2003-08 from three Northern provinces of Iran (Mazandaran, Gilan and Golestan), eight taxa of entomophthoralean fungi were identified including four pathogens of dipteran insects: Entomophaga tipulae was found on a crane fly, Entomophthora muscae was seen on five flies attached to broadbean leaves, Pandora bulata was observed only ...
