Abstract Rapid and reliable detection of pathogens is crucial to complement the growing industry of mass-reared insects, in order to safeguard the insect colonies from outbreak of diseases, which may cause significant economic loss. Current diagnosti

Bacillus thuringiensis subsp. tenebrionis (Btt) produces a coleopteran-specific crystal protoxin protein (Cry3Aa δ-endotoxin). After its discovery in 1982, the strain NB125 (DSM 5526) was eventually registered in 1990 to control the Colorado potato

Abstract Microsporidian infections of insects are important natural constraints of population growth, often reducing lifespan, fecundity and fertility of the infected host. The recently discovered Tubulinosema suzukii infects Drosophila suzukii (spot

Cydia pomonella granulovirus (CpGV) is a widely used biological control agent of the codling moth. Recently, however, the codling moth has developed different types of field resistance against CpGV isolates. Whereas type I resistance is Z chromosomal

For biological control of plant pests, e.g. cockchafer grubs, in the rhizosphere of oak, apple or pine trees, entomopathogenic Beauveria spp. are increasingly applied. For successful use, it is important to monitor the spread and persistence of the

The study involved six test fungi previously recorded in the literature as being endophytes (Beauveria bassiana, Metarhizium anisopliae, Isaria fumosorosea, Trichoderma harzianum, Fusarium proliferatum, Chaetomium globosum), two plant pathogenic fung

The presence and distribution of fungal endophytes in plants is commonly assessed by re-isolation on agar media or detection by PCR-techniques. Histological studies on the process of colonization of the host plant have only scarcely been performed. I

About 20,550 larvae, pupae and adults of the codling moth, Cydia pomonella L., were diagnosed for pathogens during long-term investigations (1955–2012) at the Institute for Biological Control in Darmstadt, Germany. The prevailing entomopathogens di

Since 2002 / 2003 black rot caused by Guignardia bidwellii is regularly occurring in organic viticulture in the wine growing areas at the Mosel and Nahe River and in the Middle Rhine valley in Germany. Though the disease originates from the USA and i
