Mycangium
The term mycangium (pl., mycangia) is used in biology for special structures on the body of an animal that are adapted for the transport of symbiotic fungi (usually in spore form). This is seen in many xylophagous insects (e.g. horntails and bark beetles), which apparently derive much of their nutrition from the digestion of various fungi that are growing amidst the wood fibers. In some cases, as in ambrosia beetles (Coleoptera: Curculionidae: Scolytinae and Platypodinae), the fungi are the sole food, and the excavations in the wood are simply to make a suitable microenvironment for the fungus to grow. In other cases (e.g., the southern pine beetle, '' Dendroctonus frontalis''), wood tissue is the main food, and fungi weaken the defense response from the host plant. Some species of phoretic mites that ride on the beetles, have their own type of mycangium, but for historical reasons, mite taxonomists use the term acarinarium. Apart from riding on the beetles, the mites live togethe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Xyleborus Glabratus
''Xyleborus glabratus'', the redbay ambrosia beetle, is a type of ambrosia beetle invasive in the United States. It has been documented as the primary vector of ''Raffaelea lauricola'', the fungus that causes laurel wilt, a disease that can kill several North American tree species in the family Lauraceae, including redbay, sassafras, and avocado. Distribution ''Xyleborus glabratus'' is native to Asia, including India, Japan, Myanmar, and Taiwan. It was first detected in the United States in 2002, and may have arrived in wood products, packing materials or pallets. ''X. glabratus'' and laurel wilt disease have since spread through much of the Gulf and Atlantic Coastal Plains, ranging from eastern Texas and Arkansas to North Carolina, and in 2019 they were found in Kentucky and Tennessee. Identification Adult The female redbay ambrosia beetle is a small (2.1 to 2.4 mm long), black or amber-brown, cigar-shaped beetle. The dorsal surface is mostly hairless and shiny whe ...

Fungi Described In 2010
A fungus ( : fungi or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms. These organisms are classified as a kingdom, separately from the other eukaryotic kingdoms, which by one traditional classification include Plantae, Animalia, Protozoa, and Chromista. A characteristic that places fungi in a different kingdom from plants, bacteria, and some protists is chitin in their cell walls. Fungi, like animals, are heterotrophs; they acquire their food by absorbing dissolved molecules, typically by secreting digestive enzymes into their environment. Fungi do not photosynthesize. Growth is their means of mobility, except for spores (a few of which are flagellated), which may travel through the air or water. Fungi are the principal decomposers in ecological systems. These and other differences place fungi in a single group of related organisms, named the ''Eumycota'' (''true fungi' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
