摘要：Major damage was caused in a short rotation plantation
for energy wood by the sawfly Nematus
pavidus. This plantation is located in the North West
region of Lower Austria, called the Waldviertel. One of
the three selected Willow hybrids (‘Inger’) was
stripped entirely leaving the other two barely touched.
By digging, the presence of a large number of vital
nymphs within the soil could be demonstrated. In
order to estimate the development, further diggings
for cocoons will be necessary in spring 2010.
Additionally, bark aphids, leaf beetles and damage
caused by cicadas were found.
