Neozygites floridana is an obligate mite pathogenic fungus in the Entomophthoromycota. It has been suggested that resting spores of this fungus are produced as a strategy to survive adverse conditions. In the present study, possible mechanisms involved in the regulation of resting spore formation were investigated in the hosts Tetranychus urticae and ...

Competition between isolates of Zoophthora radicans co-infecting Plutella xylostella populations
Interactions between Zoophthora radicans isolates were studied in vitro and in vivo during infection of Plutella xylostella larvae. We distinguished between isolates within infected hosts using PCR-RFLP. Isolates obtained from P. xylostella larvae (NW386 and NW250) were more virulent than isolates from other insect hosts.

Biological control studies require the ability to distinguish released pathogens from locally occurring isolates of the same species. We have developed a technique that differentiates genotypes using random amplified polymorphic DNA (RAPD) for the apomictic species Zoophthora radicans (Zygomycota: Entomophthorales), a pathogen of the potato leafhopper,

Stabilizing adaptation in an invasive species: Alfalfa weevil as a case study
Comparison of thermal thresholds, fecundity and longevity across three alfalfa weevil strains (California in the United States, Hamadan in Iran, Ebro Valley in Spain) reveal significant differences in demographic parameters. Weather‐driven physiologically based demographic models (PBDMs) developed from life table data explore strain adaptation to ...

Abstract The entomophthoralean fungus Zoophthora radicans is a potential biocontrol agent for larvae of the diamondback moth Plutella xylostella . Preliminary bioassays were done on 23 isolates of Z. radicans from both homologous and heterologous hosts and dose-mortality studies done on those showing most promise.
