of years. In western North America, it primarily attacks western hemlock "Tsuga heterophylla" and has only caused minor damage due to natural predators and host resistance. Accidentally introduced to North America from Japan, HWA was first found in the eastern United States near Richmond, Virginia, in 1951. The pest is now found from northern Georgia to coastal Maine and southwestern Nova Scotia. As of 2015, 90% of the geographic range of eastern hemlock in North America has been affected by HWA. An adult individual body length is typically 0.8 mm, and is oval in shape. The tiny brown-colored insect has

range of Japan. Since 1995, the DCNR's Bureau of Forestry has released hundreds of thousands of adult "S. tsugae" beetles into affected hemlock forests of the eastern United States to determine its effectiveness at controlling the spread of the adelgid. From 1995 to 1997, experiments in Connecticut and Virginia found that releasing adult "Sasajiscymnus tsugae" beetles into infested hemlock stands resulted in a 47 to 88% reduction in adelgid densities within 5 months of introduction. The beetle's lifecycle is in parallel to the lifecycle of the hemlock woolly adelgid. Both lay eggs in the spring and hatching occurs nearly simultaneously.

"Laricobius osakensis" from Japan, a relative of "L. nigrinus". They have shown promise in field trials. The environmentally safest chemical control methods for treating individual trees are nontoxic insecticidal soap and horticultural oil. These are sprayed on the foliage and smother the insects as they dry. Most trees need to be treated on a yearly basis. Toxic systemic insecticides may be applied to the foliage and bark of a tree and can persist in killing the adelgid for up to four years after application. Caution must be used, and restraint exercised around bodies of water. Soil drenches/soil injections/bark sprays are

the Assistant Chief of the Naval Staff (Warfare) it existed until 1968. The directorate was originally established in December 1912 as the "Navigation Department" of the Admiralty then part of the department of the "Hydrographer of the Navy". Following changes in the command structure of the "Admiralty Naval Staff" (1917-1919) the department and thus Director of Navigation came under direct control of the First Sea Lord until 1945. In July the "Navigation Department" was renamed the Navigation Division and now as part of the Naval Staff. In 1946 it was renamed the "Navigation and Direction Division". The division existed as

It was confirmed on 15 May 2013 that Turkish Süper Lig side, Galatasaray and Serie A side Napoli were to Arsenal's opponents although this did not receive a good reception from Arsenal fans after the 2000 UEFA Cup Final riots where Arsenal and Galatasaray fans clashed in Copenhagen, Denmark before the Uefa Cup Final. The third side was Porto who played their two games against Arsenal's two opponents. Arsenal's final pre-season friendly was against fellow Premier League side

required amputations, with some suffering traumatic amputations as a direct result of the blasts. Police, following emergency plans, diverted arriving runners to Boston Common and Kenmore Square. The nearby Lenox Hotel and other buildings were evacuated. Police closed a 15-block area around the blast site; this was reduced to a 12-block crime scene on April 16. Boston police commissioner Edward F. Davis recommended that people stay off the streets. Dropped bags and packages, abandoned as their owners fled from the blasts, increased uncertainty as to the possible presence of more bombs and many false reports were received.

"Super Mario Bros. 2" yielded ten million copies sold and was the third highest-selling game ever released on the Nintendo Entertainment System at that time. "Nintendo Power" listed "Super Mario Bros. 2" as the eighth best Nintendo Entertainment System video game, mentioning that regardless of its predecessor not being a "Mario" game, it was able to stand on its own merits and its unique takes on the series' signature format. "Super Mario Bros. 2" was ranked 108th out of 200 of the "Greatest Games of Their Time" by "Electronic Gaming

The archaeological relics identified at Castle Hill, and other relics potentially on the site but not yet exposed, hold considerable potential to contribute to substantive research questions relating to important trends in the state's (and nation's) history, including the treatment of the convicts and mental health patients incarcerated at the site, the circumstances precipitating the Battle of Vinegar Hill, early attempts at agriculture west of Sydney, and (at the local level) the settlement and later development of the area around Castle Hill.

Oregon all can serve as a host. Extensive mortality due to this pest in the Cascade Mountain range was recorded during the 1950s and 1960s. Land area affected by the adelgid in the Pacific Northwest has increased from 83,325 acres (337 km) in 2004 to 108,128 acres (438 km) in 2005. Balsam woolly adelgid Balsam woolly adelgids (Adelges piceae) are small wingless insects that infest and kill firs, especially balsam fir and Fraser fir. They are an invasive species from Europe introduced to the United States around 1900. Because this species is not native to the United States, the Fraser

were swept by a wildfire which has given the area an awkward mix of young shrubbery and woods, but this portion is rather short and within a mile the trail passes into the spruce-fir zone, which has also had problems more recently with air pollution and the balsam wooly adelgid. At the trail comes to a split with the Forney Creek Trail, which, to the right, leads down to Fontana Lake. From here the trail actually rises up for about a quarter mile, the only such notable jaunt along its path, before leveling out and gently sloping back down to

the teddy bear came to be in its current state. A third generation Tatty Teddy was introduced in May 2009. This bear has much longer fur in various shades of grey and a blue plastic nose, rather than the fabric nose on previous generations. The reflective spot has been removed since the new plastic nose has reflective qualities. The bears come in many different sizes, ranging from 5 cm to in excess of 80 cm, and often come with accessories such as hearts, roses, T-shirts, wooly hats and scarves. Some have personalised messages from a simple "I Love You" to

features like beards, mustaches, and shaggy eyebrows on the face." The brothers Donald and James Herzog developed Wooly Willy while working in the Smethport Specialty Company, their father's toy production company, in Smethport, Pennsylvania, United States. The company produced tops, horseshoe-shaped magnets, and other toys until the vacuum forming devices of the 1940s and 1950s allowed the company to manufacture air-tight containers of transparent plastic. Such containers kept Wooly Willy's metal filings from leaking out and moisture that would rust the metal from leaking in. The artwork for the first Wooly Willy was created by artist Leonard Mackowski of nearby

panels and numerous windows cover most of the outside perimeter of the cabins. From the 1960s through 1980s, they hardly seemed necessary, for the hemlock trees formed a thick canopy and kept the shaded grounds cool. However, in the early 1990s, the hemlock woolly adelgid began destroying the hemlock trees, so the surrounding forest is again scattered with dead and fallen trees as in Hoover's day. The cabins are equipped with electricity and plumbing, with visible wiring snaking along the walls and rafters. Large elevated outdoor decks were built with holes for the trunks of mature live trees, whose branches
