Abstract

Porovnanie odchytov lykožrúta smrekového (<italic>Ips typographus</italic> L.) (Coleoptera: Scolytidae) do feromónových lapačov kanadskej a európskej produkcie

Research was carried out in High Tatra and Low Tatra Mountains in 2009. It was aimed to compare the efficiency of two types of pheromone traps (Lindgren funnel trap and Theysohn trap), two types of lures (Ipslure and Pheroprax A) to control the spruce bark beetle (Ips typographus), characterize flight activity pattern of I. typographus and identify bark beetle species caught in traps. Altogether 40 traps were set up for bark beetles (16 traps in Low Tatra Mountains and 24 traps in High Tatra Mountains). Lindgren funnel traps yielded higher catches of I. typographus (by 18.2% on average) than Theysohn traps, although this was not statistically significant (p > 0.05). The traps baited with Pheroprax A caught a total of 3,833 individuals of I. typographus per trap, those baited with Ipslure 1,587 individuals per trap. In this particular case, the difference in the bark beetle catches between the two lures was statistically significant (p < 0.05). The flight pattern of I. typographus in both mountain areas was similar. It showed great decrease in abundance of flying individuals of I. typographus as a result of low temperatures in the middle of June. Flight patterns of the bark beetle in the two mountain areas were similar to those documented from other sites monitored in Slovakia over the growing season 2009. Altogether 25 bark beetle species (22 species in High Tatra Mts., 18 species in Low Tatra Mts.) and 1,066,494 individuals were caught. I. typographus was the dominant scolytid species in traps (over one million adults caught). Other important (abundant) bark beetles included Pityogenes chalcographus (15,914 adults), Xyloterus lineatus (2,008 adults), Dryocoetes autographus (308 adults), Hylastes cunicularius (421 adults), Hylurgops palliatus (227 adults), Orthotomicus laricis (77 adults), Crypturgus cinereus (76 adults), Polygraphus poligraphus (45 adults), followed by other less abundant and less important bark beetle species.

Abstract

Priebeh jarných fenologických fáz na generatívnych orgánoch autochtónnych populácií smreka obyčajného (<italic>Picea abies</italic> [L.] Karst.) zo Slovenska

The results of phenological observations of the generative organs of Norway spruce (Picea abies [L.] Karst.) in the Zvolen Basin are analysed. Twenty autochthonous spruce populations taken from its natural areas of distribution and planted in the Arboretum of Borova Hora belonging to the Technical University of Zvolen present the altitudinal range of 500-1,450 m. The 10% beginnings of phenological stages as a Flower buds swelling, a Formation of flowers before blossom, flowering and blossom fall were observed during the period of 2006-2008. Flower buds swelling occurred on its average from 12th till 21st of April and lasted 9-11 days predominantly. The formation of flowers before blossom occurred from the 23rd of April till the 2nd of May and lasted 5-6 days. The stage of Flowering began on its average from 29th April till 8th May and predominantly lasted 5-6 days. Blossom fall occurred on average from 5th till 17th May and predominantly lasted 11-12 days. The earliest occurrence of phenological stages was recorded in years 2007 and 2008, while a moderate delay in the year of 2006 caused by low temperature and long lasting snow cover. Variation coefficients approached values from 0.57 up to 3.19%. The equalization of air temperature course during the later spring period resulted in the observed decrease of variability of both the Flowering and Blossom fall. The altitude of original sites, the observed provenances come from, has not influenced neither the time of particular phenological stages beginnings nor the lengths of their periods. The conditions of a new environment proved to be decisive.
