ENVIRONMENTAL FACTORS AFFECTING PERSISTENCE OF ENTOMOPATHOGENS
This symposium review will focus on the impact of environmental factors (primarily sunlight, temperature, humidity-water) on the field persistence of selected representative species ofExpand
Relationships among enzyme activities and virulence parameters in Beauveria bassiana infections of Galleria mellonella and Trichoplusia ni
TLDR
Levels of specific cuticle-degrading enzymes showed relationships with specific virulence parameters and the conventional parameter of LT50 was the product of two strain-specific parameters that may be described as "onset of mortality and subsequent "rate" of mortality. Expand
Inactivation of Representative Species of Entomopathogenic Viruses, a Bacterium, Fungus, and Protozoan by an Ultraviolet Light Source
Four entomopathogenic viruses and one each of an entomopathogenic bacterium, fungus, and protozoan were inactivated when exposed to ultraviolet light; the half-life was less than 4 h in everyExpand
Levels of chitinolytic activity during development of three entomopathogenic fungi
TLDR
Low activity was measured during the growth stage when the fungi initially penetrate the insect cuticle and maximum activity occurred at a time when N- acetylglucosamine is necessary both for fungal growth and conidia formation and when the conidiophore exits the host. Expand
Replication and infectivity of the single-embedded nuclear polyhedrosis virus, Baculovirus heliothis, in homologous cell lines
TLDR
The PIB from all cell lines produced typical symptoms of an NPV infection when bioassayed against larvae of H. zea . Expand
Insect cuticle-degrading enzymes from the entomogenous fungus
TLDR
Natural strain variability in enzyme levels was significant, and there was no evidence of coordinated expression, suggesting that it may be possible to tailor biological control agents against specific targets. Expand
Uv-Photoinactivation of Cells and Spores of Bacillus thuringiensis and Effects of Peroxidase on Inactivation
TLDR
The findings supported the assumption that sunlight inactivation of entomopathogens probably is caused by peroxide or peroxide radicals produced by the UV irradiation of amino acid (s). Expand
