Abstract Co-inoculation of Zoophthora radicans and Pandora blunckii in Plutella xylostella larvae were investigated. Co-inoculations were made simultaneously or within 4, 8 or 12 hr of each other to achieve different prior residency times; order of inoculation was alternated.

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.

Abstract Conidial germination, appressorial formation, and secondary sporulation in Zoophthora radicans occurred independently of DNA replication and nuclear division. Video-image analysis combined with epifluorescence microcopy showed that at 18 hr postinoculation, approximately 10% of germlings had undergone the first DNA duplication and nuclear ...

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.

Zoophthora radicans primary and secondary ovoid conidia inoculated onto Empoasca kraemeri fifth-instar nymphs germinated in three alternative modes, forming either germ-tubes, capilliconidiophores or replicative conidiophores. Production of germ-tubes was positively correlated, and production of capilliconidiophores inversely correlated, to ...

Development of a natural epizootic of Zoophthora radicans in an Empoasca kraemeri population on beans near Goiânia, Goias, Brazil, was monitored over a 6-week period. At the initiation of monitoring on 23 April 1985, disease prevalence in the leafhopper population was 12.8%.
