Question

Answer

Dobrý deň pani Babjaková, nakoľko sa na obrázku nenachádzajú plodnice drevokaznej huby, predpokladám podľa typu hniloby, že sa jedná o poškodenie koreňovkou vrstevnatou. Jedná sa o staršie napadnutie, v poslednom štádiu degradácie dreva. Taktiež je viditeľné poškodenie jadra aj drevokazným hmyzom, pravdepodobne mravcami. Pekný deň s pozdrabvom Roman Leontovyč.

Question

Dobrý deň, chcel by som vedieť čo to je za technického škodcu. Váhal som či sa jedná o jaseň, nakoľko je drevo v rozklade, tak som si nie istý. Na tomto odkaze je viac fotiek. Ďakujem za odpoveď. odkaz: https://easyupload.io/m/674dup

Answer

Dobrý deň. Ani ja som si neni istý či sa jedná o jaseň. Poškodenie tu spôsobil takmer určite drvinár hnedý. Pozrite si viac fotiek v našom atlase + video. S pozdram JG

Question

Približne polovica vetiev koruny japonskej vŕby mala na strihu dutinu v centrálnej časti konárov. Niektoré vetvy sa dali zostrihnúť do zdravého dreva, niektoré veľké vetvy mali aj pri hlavnom kmeni dutinu. Obávam sa že, to pokračuje do hlavného kmeňa.

Answer

Dobrý deň. Teoreticky sa môže jednať o poškodenie od lariev fuzáča dvojbodkového, ktorého nájdete aj v našom atlase (https://www.skodcoviadrevin.sk/skodca/fuzac-dvojbodkovy&rurl=YXRsYXMmYW1wO2ZpbHRlcj05NyZhbXA7cD0y). Pomôže opakovaný postrek insekticídom v júni až auguste. Prípravok vám poradia v každom záhradkárstve. S pozdravom JG

Zdravím. Požerok bol nájdený na rozštiepenom dubovom kláte. Dub s ktorého požerok pochádzal bol vyvrátený a čiastočne uschnutý. Domnievam sa že škodca bol Cerambyx Cerdo

Answer

Dobrý deň. Áno, požerok patrí takmer na 100% fuzáčovi veľkému (Cerambyx cerdo). S pozdravom JG

Hello, I think that damage is caused by Cerambycidae, probably Arhopalus rusticus or may be Spondylis buprestoides.  Best regards Jozef Vakula

Dobrý deň Požerok na kmeni je od Lykokaza borovicového Tomicus piniperda. Dospelé jedince ktrore ste poslali sú pravdepodobne Orthotomicus longicollis vľavo na fotke (ten bez výrazných zúbkov na konci kroviek) a druhé imágo je lykožrut vrcholcový Ips acuminatus ten v pravo so zúbkami na konci kroviek.   ďakujem za váš dotaz ML
