Mycoviruses infecting the endophytic and entomopathogenic fungus Tolypocladium cylindrosporum.
A mixed virus infection in a strain of the endophytic and entomopathogenic fungus Tolypocladium cylindrosporum was deduced from a study of the transmission to conidia of several double-stranded RNA (dsRNA) elements. The transmission rates of each dsRNA were different, and monosporic isolates harbouring different combinations of the original set of six dsRNAs were obtained. A 5196 bp dsRNA eleme...
متن کاملStudies on bioassay of the entomopathogenic hyphomycete fungus Tolypocladium cylindrosporum in mosquitoes.
Larvae of Aedes aegypti, Ae. vexans and Culiseta inornata were used to study the pathogenicity of the hyphomycete fungus Tolypocladium cylindrosporum. Experiments consisted of continuous exposure of second-instar larvae to 5 concentrations of conidia at 10, 15, 20 and 25 degrees C. The 3 test species were susceptible at all temperatures tested. There was generally a direct relationship between ...
متن کاملPathogenic and enzyme activities of the entomopathogenic fungus Tolypocladium cylindrosporum (Ascomycota: Hypocreales) from Tierra del Fuego, Argentina.
Tolypocladium cylindrosporum is an entomopathogenic fungi that has been studied as a biological control agent against insects of several orders. The fungus has been isolated from the soil as well as from insects of the orders Coleoptera, Lepidoptera, Diptera and Hymenoptera. In this study, we analyzed the ability of a strain of T cylindrosporum, isolated from soil samples taken in Tierra del Fu...
متن کاملthe effects of entomopathogenic fungus, tolypocladium cylindrosporum on cellular defence system of galleria mellonella
the entomopathogenic-fungus-life cycle is associated with the synthesis and secretion of a number of toxic metabolites, including extracellular enzymes and the low-molecular weight compound (toxin). the potential for a successful pathogen relies on the ability to overcome the various host-defence systems. interaction between the fungus, tolypocla-dium (deuteromycetes), its secondary metabolite,...
متن کاملPreliminary field trials with the entomopathogenic hyphomycete Tolypocladium cylindrosporum in central Alberta.
Conidia and blastoconidia of the pathogenic hyphomycete Tolypocladium cylindrosporum were applied to temporary and semi-permanent pools in central Alberta on 6 occasions. Infections were detected in the field only following application of blastoconidia; indications were that infections did not occur in the field following application of conidia. Most infections were detected only after holding ...
