Pests Affecting Shiitake Mushrooms


Pests Affecting Shiitake Mushrooms

Greg Frey- Virginia State University


There are some pests that are often noticed in association with shiitake mushroom production.  Fortunately, there are not a large number of pests that cause serious problems.  The principle problem with shiitake may be from other fungi that affect the log and shiitake mycelia.  Because the fruiting bodies grow quickly on the log and should be harvested quickly before the mushroom caps get flattened out, there is not usually a lot …

Aquatic (Water-Dwelling) Invasive Species

Aquatic (water-dwelling) invasive species are non-native plants, animals, and other organisms that have evolved to live primarily in water (aquatic habitats) rather than on land (terrestrial habitats). Aquatic habitats are habitats that are covered with water all or part of every year. From oceans to bogs, many types of aquatic habitats exist. Aquatic invasive plants include algae, floating plants, submersed plants, and emergent plants. Aquatic invasive animals include insects, fish, reptiles, mollusks, crustaceans, and amphibians. Other aquatic invasive organisms include …

What Are Invasive Species, and Why Should We Be Concerned About Them?

An invasive species is a nonnative species (in any reproductive stage, including seed, egg, spore, or other propagule) whose introduction causes or is likely to cause economic harm, environmental harm, or harm to human health. These species grow and reproduce rapidly, causing major disturbance to the areas in which they are present.
