Research on merocoenoses of cambioxylophagous insect fauna of Norway spruce (Picea abies [L.] Karst.) was carried out in spruce stands of different age in the area with an endemic population (Moravian...
The efficiency of two types of pheromone dispensers (ECOLURE classic and ECOLURE tubus) was compared in 2008. Pheromone-baited traps were checked 13 times in 10-day intervals (this guaranteed the effi...
Spruce is regarded as the only host plant of Ips duplicatus in Central Europe, whereas this beetle exceptionally occurs on pine in Siberia. Its occurrence on Pinus strobes and Pinus sylvestris was dis...
Good knowledge of geobiocoenoses is one of the primary preconditions for biogeographical differentiation of the landscape, protected territory tending and preservation of forest ecosystems. For deepen...
In digestion, the red palm weevil, Rhynchophorus ferrugineus, has been adapted to overcome the plant cell wall barrier, specially lignocellulosic and pectic compounds, by producing cellulase and pec...
