needle drop - Opis:
- The threat of infestation by pine−shoot beetles in Występa stands was assessed on the basis of the needle drop in the Zagnańsk Forest District in the period 2001−2002. The efficiency of the entomological monitoring and undercanopy plots method used for the collection of damaged needles was assessed. Research results indicate that the forecasts of pine−shoot beetles in forest practice using one or two undercanopy study plots can appear to be the cause of the error in assessing the degree of infestation of stands. The method of entomological monitoring is more representative and efficient thanks to the greater area of needle collection irrespective of the closing of the canopy.
