lime - Opis:
- In April 2005, 2 sets by 3 stacks containing Norway spruce logs were exposed in sunny and shaded place within the forest. In each set logs in 2 stacks were sprayed with Ca(OH)2 aquatic dilution with the addition of milk and vegetable oil (1 stack as a whole, and 1 individually – log by log), and 1 left for control. At the end of June 9 insect species infesting the logs were found, among which the most frequent were Hylurgops palliatus (Gyll.) – 41,1% and Pityogenes chalcographus (L.) – 35,6%. The treated logs were less (sometimes – significantly) infested by the most frequently occurring species, but the difference between two variants of treatment was not very high. The logs exposed in sunny place were less infested than those stocked under stand canopy. As this environmentally friendly treatment reduced the infestation of logs by bark beetles (including I. typographus), it can be recommended especially for mountain areas under protection regime.
