TLDR
This study is the first detailed characterization of E. aulicae from P. scabra larvae and found Pyriform, multinucleate conidia and spherical to slightly oval resting spores were the primary features of this fungus.Abstract:
Entomophaga aulicae was monitored in populations of noctuid lepidopteran pests of soybean during the 2000, 2001, and 2002 growing seasons in South Carolina and infected only Plathypena scabra larvae. No infection by E. aulicae was detected in 2002. Average infection levels of E. aulicae in P. scabra populations in Blackville were 6.0% and 20.0% in 2000 and 2001, respectively. At Clemson, infection was 15.0% and 23.3% for the two sampling weeks in 2000, and infection reached a high of 50.0% in 2001. Pyriform, multinucleate conidia and spherical to slightly oval resting spores were the primary features of this fungus. When conidia were kept in a high humidity for 6-12 hrs they either formed long germ tubes or secondary conidia. Resting spores were formed by budding from parental cells. This study is the first detailed characterization of E. aulicae from P. scabra.read more

TL;DR: Investigating the ecology of Entomophaga aulicae at three sweet potato fields in Korea and further characterized its biological features suggests that this isolate can be an effective biological control agent against the serious sweet potato leaf worm.

Allozyme and restriction fragment length polymorphism analyses confirm Entomophaga maimaiga responsible for 1989 epizootics in North American gypsy moth populations.
TL;DR: Allozyme and restriction fragment length polymorphism analyses are used to confirm the identification of E. maimaiga, a mycopathogen reported only from gypsy moth populations in Japan, as the cause of mortality in late instar larvae on research sites in central Massachusetts during 1989.

Isolation and characterization of Entomophaga maimaiga sp. nov., a fungal pathogen of gypsy moth, Lymantria dispar, from Japan
TL;DR: Among the isolates of E. maimaiga from Japan, ARSEF 1400 appeared most promising for biological control use; it caused 90–95% mortality in third instar larvae after an average of 5.2 days and can be cultured in both protoplast and mycelial vegetative stages.
