Povzetek

V naših krajih so termiti prisotni le na nekaterih predelih Primorske, v Mediteranu in tropih pa se veliko bolj soočajo s tem problemom. Namen raziskave je ugotoviti odpornost nekaterih proizvodov na rumenovratega termita. Preučevali smo učinkovitost 3 različnih kombinacij proizvodov za zaščito lesa na smrtnost rumenovratega termita. Smrekove vzorce (50 mm x 10 mm x 10 mm) smo impregnirali z različnimi kombinacijami zaščitnih pripravkov na osnovi bakra, etanolamina, kvartarne amonijeve spojine, bora in oktanojske kisline. Na vzorce smo namestili steklene valjčke premera 15 mm. Vzorce s termiti smo hranili v komori pri temperaturi 26 °C in relativni zračni vlažnosti 90 %. Smrtnost termitov smo spremljali 16 tednov. Preizkus je bil opravljen po Beckerjevi metodi (1969). Ugotovili smo, da so bile vse uporabljene kombinacije zaščitnih pripravkov najbolj učinkovite na drugi dan spremljanja; razlike med končno smrtnostjo pa so bile pri vseh uporabljenih proizvodih zanemarljive. Prav tako pa se je nepričakovano pokazala velika smrtnost pri kontrolnih vzorcih. Na osnovi pridobljenih rezultatov smo ugotovili, da uporabljeni termiticidi niso najbolj učinkoviti.

Sekundarni naslov: Efficiency of copper, ethanolamine and quartenary ammonium based compound against the attack of yellownecked termite
Sekundarni povzetek: In our local sites, termites are present only in some regions of Primorska, Mediterranean regions and Tropics are more affected with this problem. The purpose of the research is to determine the resistance of some chemical compounds on yellownecked termite. The aim is to define the efficiency od 3 different wood impregnations on the mortality of yellownecked termite. The spruce samples (50 mm x 10 mm x 10 mm) were impregnated with different products. We placed 15 mm glass cylinder on the samples. The samples with termites were placed in a chamber with temperature of 26 °C and 90 % humidity. The state of termites was controlled for 16 weeks. The test was made with Becker's method (1969). We found that all used combinations of preservative preparations were the most effective on the second day of monitoring, the difference between final mortality of all used products was negligibile. It also, however, showed unexpectedly large mortality in the control samples. Based on the obtained results the termiticides used were not most effective.
