Comparison of bark boring species composition on douglas-fir and pine
Košík, Kamil ; Pešková, Vítězslava (advisor) ; Šenfeld, Petr (referee)
This work deals a comparison the diversity of species of bark beetles on Douglas fir (Pseudotsuga menziesii Mirb./Franco) and Scots pine (Pinus sylvestris L.). On location the Green Shed in the Central Region of the Czechia were laid 24 traps, so that Douglas fir and Scots pine formed a couple. They were prepared two variants - trees up to 30 years and a trees of 40 - 60 years old. Evaluation took place after four sections in the relative distances. Research has shown that the both species of the trees were not broad spectrum of bark beetles. On Douglas fir it was only a Pityogenes chalcographus L., who was found in only one trap tree at the age of 30 years, and on the Scots pine trap tree was found only Tomicus piniperda L., but it was found in most traps.
