Characterization of Spanish strains of Verticillium lecanii.
We have characterized biologically and physiologically eight Verticillium lecanii strains from several origins including insect pests. Of all the temperatures tested, 25 degrees C was the best for growth and at 40 degrees C none of the strains could grow. At 4 and 7 degrees C, growth was reduced in comparison to warmer temperatures. The strains had better development at pH close to 7 (F = 27.64...
متن کاملVegetative compatibility, host range and pathogenicity of Verticillium dahliae isolates in Iran
Verticillium wilt is an economically important disease which inflicts serious losses in potato, cotton, alfalfa, some vegetable crops and fruit trees and occasionally ornamentals. Verticillium dahliae, infected cultivated species and weeds were collected from several areas in Iran during tewelve years from 1993-2005 and studied for their vegetative compatibility, host range and pathogenecity. T...
متن کاملProduction of extracellular enzymes in the entomopathogenic fungus Verticillium lecanii
This study investigates the mechanisms as well as strategies for purification and characterization of potential enzymes involved in pathogenesis of entomopathogenic fungi. The test strain of Verticillium lecanii that was screened, during the present investigation, proved to be an efficient producer of protein and polysaccharide degrading enzymes (amylase, protease, and lipase), hence indicating...
متن کاملبررسی آزمایشگاهی بیماری زایی قارچ Verticillium lecanii (Zimm.) Viegas روی شته نخود فرنگی [Acyrthosiphon Pisum (Harris)]
Pathogenicity and virulence of entomogenous fungus, Verticillium lecanii, was studied on the pea aphid, Acyrthosiphon pisum. Vertalec, a commercial product of V. lecanii, was evaluated under controlled conditions. Second instar nymphs were inoculated with conidial suspensions at concentrations ranging from 104 to 108 conidia/ml, and sterile distilled water (containing wetting agent) as control,...
