Research and development on alternative sources of energy has been a priority for the United States since volatile energy prices in the 1970’s. This period of time, known as the “Energy Crisis,” occurred due to an oil embargo and limited global supply of oil. To combat these problems, Congress passed the Emergency Petroleum Act in 1973, the Energy Policy and Conservation Act in 1975, and created the Department of Energy in 1977. These congressional acts from more than 30 years ago were the beginnings of a national interest towards developing alternative energy sources. The outcome has been support for research and development of non-petroleum energy sources such as biomass, which is a renewable and carbon neutral source of energy used for heat, electricity and transportation fuels.

Four species of Ips bark beetles (also commonly known as Ips engraver beetles or Ips beetles) occur throughout pure and mixed pine forests in the southeastern U.S.: the six-spined ips (Ips calligraphus), the pine engraver (Ips pini), the eastern five-spined ips (Ips grandicollis), and the small southern pine engraver (Ips avulsus). Ips beetles appear similar to other bark beetles in this region, including the southern pine beetle (SPB), black turpentine beetle, and red turpentine beetle. These beetles occur throughout the entire southeastern U.S., with the exception of the pine engraver and red turpentine beetle, which are found only in the Appalachian region.
