Posouzení účinnosti stromových mikroinjektáží jako metody aplikace navnaděných stojících otrávených lapáků na LZ Boubín
 Řezník, Pavel
The topis of this thesis was to evaluate the effectiveness of tree microinjection as a method of forest protection management. The evaluated data were following:maternal and larval corridors lengths of Ips typographus and mortality of I. typographus on treated and control trees in photoeleclectors . Data collected during the field experiments were statistically tested for the presence of differences using non-parametric analysis of variance (Kruskal-Wallis, resp. Dunn's t-test). The secondary aim of this thesis was to assess the use of the method as a poisoned standing baited trap in forestry practice in the Klet' forest area belonging to the Boubín Forestry Plant (Lesy České republiky, s. p.). Both measurements of the length of maternity and larval tunnels and the amount of beetles captured from photoeleclectors showed significant effectivity on reducing of I. typographus development and increased mortality pressure for spruce bark beetle adults.

Zhodnocení efektivity stromových mikroinjektáží jako metody tvorby navnaděných stojících otrávených lapáků na lýkožrouta smrkového (Ips typographus Linnaeus, 1758) na lesních pozemcích Města Poličky

Many technologies are currently used in practice for pest management and control. One technology that is becoming more widely used is the microinjection method. This method is the focus of this thesis, which specializes in the use of microinjection as a defensive method against the European spruce bark beetle (Ips typographus (Karst.) L.). The investigation took place in 2022, when 25 trees were injected at 5 sites before the start of spring swarming. In addition, 5 control trees were selected at each site and I. typographus was baited with a synthetic pheromone. The effectiveness of this method was then evaluated by comparing the lengths of the mother galleries and larval galleries on the debarked bark strips and by means of a photo-eclector experiment. The data were then statistically evaluated using the Kruskal-Wallis test, which showed that bark beetles on trees treated with injection had significantly shorter mother and larval galleries. The photo-eclector survey showed that the number of I. typographus from logs that came from injection-treated trees accounted for only 10.88% of the total number of imagoes captured. This value demonstrates that microinjection is not only an effective method against leaf miners and skeletonizing insects on deciduous trees, but its application can also be in the management of bark beetles on spruce.
