摘要：Forest Protection Situation 2005 in Austria
Despite a cooler, wetter summer than in recent years,
many pest insect species continued their gradation. The
damage by spruce bark beetles reached a historical high
with more than 2.5 million m3 timber affected. Other
Scolytidae, Buprestidae and Cerambycidae species showed
an increased presence in 2005 too. Damage by defoliators,
especially winter moths, increased. The Gypsy moth
extended its area, and appears to stand just before a
gradation in 2006. Due to the moister conditions, regionally
known diseases, mainly leaf and needle fungi were
observed more often.
During an intensive survey in the city of Braunau, four
additional trees infected by Anoplophora glabripennis were
discovered. All infected trees were cut down, chipped and
burned. The Phytophthora ramorum survey revealed no
positive findings.
