The Controversy Over the Brown Spruce Longhorn Beetle

A small bug about the brown spruce long horn beetle caused a fierce argument between the Halifax municipal authorities and the citizens. This small insect is native to Europe, it is thought that it arrived at a container ship about 10 years ago, there is a possibility to destroy the largest and busiest park of Halifax, especially the brown spruce long horn beetle It is known as. And there is the possibility of destroying the entire Nova Scotia state, and even Canada's vast forests are not active.

Long horn beetle (also called Cervium, long horn or long horn beetle or long horn beetle) is usually a very long antenna, usually the worldwide family of the same length or long beetle as the body of the beetle. However, among the various members of the family, the antenna is very short (eg Neandra brunnea), and these species are difficult to distinguish from related beetle families such as family A. This family is large, representing over 26,000 species, slightly over half of the eastern hemisphere. There are several kinds of serious insect pests. Larvae known as round locusts pierce the trees where they can live or untreated trees (or sometimes serious damage to the trees in the building, old house grasshopper, Hylotrupes bajulus, It is a special issue). Most seeds are faint, but many species mimic ants, bees, wasps

Conifers can be used as host for various tree boring beetles, spruce beetle, bark beetle and ips beetle (Ips species). These insects contribute to the decomposition of wood and the release of nutrients. Some beetles have shells with specific indentations that match the shape and size of fungal spores, especially those that break down the wood. Fungal spores become firmly embedded in these cup-like structures. When a beetle digs into a tree, they plant a fungus. The abundance and total biomass of soil organisms were significantly lower in coniferous stands than in low latitudes. Major soil organisms are protozoa, nematodes, rotifers and slow moving animals. These creatures inhabit mainly in soil water film and interstitial water in soil. Soil fauna of coniferous forests is unique. Particularly in coniferous forests in the central and northern part, there are no large invertebrates such as Yasuda, isopoda (fountain), cricket and the like.
