Invasive species are a major cause of ecological damage and commercial losses. A current problem spreading in North America and Europe is the vinegar fly Drosophila suzukii. Unlike other Drosophila, it infests non-rotting and healthy fruits and is therefore of concern to fruit growers, such as vintners. Consequently, large amounts of data about infestations have been collected in recent years. ...

In this study, we characterized sporadically occurring sclerotium rot caused by Sclerotium rolfsii in Chinese chive (Allium tuberosum Roth.) in farm fields in Sacheon, Korea. The initial symptom of the disease was water-soaked, which progressed to rotting, wilting, blighting, and eventually death. Further, mycelial mats spread over the lesions near the soil line, and sclerotia formed on the sca...

The collar rot disease has been reported recently and occurs at the 10-12-leaf stage of plants of opium poppy. Infected plants topple down and dry prematurely due to fast rotting at the collar region. The inoculum for this study was multiplied on the cornmeal-sand culture. Genetic ratios were calculated by the chi-square test. Inheritance studies on this disease show a monogenic pattern of segr...

Since 1996, the primary objective of the New Crop Pathology Program at the University of the Free State has been to conduct a systematic survey of diseases occurring in cactus-pear [Opuntia ficus-indica (L.) Miller] orchards throughout the country and to investigate possible relationships between disease-causing microorganisms and various insects, specifically Drosophila sp. Numerous fungal gen...

FRESH-WATER hyphomycetes from tropical locations have been reported by Ingold (1 956, 1958 , 1959, 1960 ) , Dixon (1959) , Greathead (1961) , Hudson (1961), Hudson and Ingold ( 1960 ) , and Nilsson ( 1962) . Reports from the Pacific area include California (Ranzoni, 1953) , and Japan (Tubaki, 1957, 1960; Suzuki and Nimura, 1960a, b; and Nimura, 1960 ). The Fungi Imperfecti reported in this pape...

In the course of a study of the enzymes of Piricularia oryzae Cav., the fungus causing the blast disease of rice, it was observed that activity of crude polyphenoloxidase preparations from culture filtrates was not inhibited by sodium diethyldithiocarbamate (DEDTC), a widely used inhibitor of copper-containing enzymes. Further investigation revealed that such preparations contained an enzyme wh...

Decomposition of C-labeled lignin to CO(2) by the lignin-decomposing fungi Phanerochaete chrysosporium and Coriolus versicolor required a growth substrate such as cellulose or glucose. Growth with lignin as sole carbon addition to an otherwise complete medium was negligible.

Although current interest in basidiomycete fungi is focused mainly on taxonomy and exploitation of selected species in environmental biotechnology, isolation and characterization of their nucleic acids is becoming still more and more important for many purposes. Differences in cell wall composition and the mode of growth of some basidiomycetes are the major limitations for utilization of common...

Digitized growth pattern images of wood-rotting fungi Fomitopsis palustris (FOM) and Trametes versicolor (TRA) were used with a video processing program new formula to calculate the numerical results microbial inhibition by an active substance (wood vinegar). First, daily collected generate calibration curves for each fungus. FOM stopped growing in 7 days, whereas TRA 11 days. The showed R2 = 0...
