The widespread fungal pathogen Zoophthora radicans kills both adult and larval stages of the diamondback moth. At IACR-Rothamsted, a novel strategy for diamondback moth control, based upon a fast entry/ slow exit trap containing the female sex pheromone and the pathogen, is under development. Male moths are attracted into an inoculation chamber where they are showered with infective conidia of ...

AIMS To isolate and formulate a native strain of Zoophthora radicans naturally infecting larvae of diamondback moth, Plutella xylostella, existing in South Australia and to provide evidence that formulation of the fungus is effective against P. xylostella larvae, and therefore, it could be used as a tool in pest management of this insect. METHODS AND RESULTS Dose-response bioassays using form...

Abstract The alfalfa weevil ( Hypera postica Gyllenhal, Coleoptera: Curculionidae) is a major pest of crops. Chemical control measures are inefficient, but the larvae often infested by parasitoid wasps genus Bathyplectes Förster (Hymenoptera: Ichneumonidae), which offer potential biological strategy. development effective requires identification species, conventional methods involve rearing par...

Larval food consumption and weight gain were not affected by Z. radicans until the third day after infection, one day prior to death from mycosis. No food was eaten on the day on which larvae died. Overall, infected larvae ate 45% less leaf tissue than uninfected larvae. Of the leaf tissue consumed by infected larvae, 87.5% was eaten on the first two days after infection and after this time inf...

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 ...

The larvae and less frequently the pupae of Plutella xylostella (L) are sometimes attacked naturally by pathogens, particularly two fungi of the family Entomophthoraceae, Erynia blunckii and Zoophthora radicans. Other pathogens recorded include one other entomophthoraceous fungus, a granulosis virus, one or possibly two nucleopolyhedrosis viruses and Bacillus thuringiensis var kurstaki. In the ...
