Question

Hello, could you please help me to identify the little pest that left these galleries? Thank you very much in Advance. Best regards, Antonella

Answer

Hello,even though the galleries are old, I think it is Pityokteines vorontzowi. It is possible to confuse it with the species Pityophthorus pityographus, which has longer maternal tunnels and density larval tunnels.Best regardsJozef Vakula

Question

Hi, in this branch there are two types of traces. Could you tell me which kind of insects left them? Thank you very much! Best regards Antonella

Answer

Dear Antonella. The gallery with long tunnels looks like from Pityogenes bidentatus (commom on pine) and the third pictures looks like gallery created by Buprestidae family, I guess Anthaxia spp. See these species in our atlas or just Google it. Best regards, Juraj

Question

V takomto stave je asi skoro rok , neviem čo sa mi mohli stať ale vo vnútri má zelené ihlice.

Answer

Dobrý deň, ospravedlňujeme sa za oneskorenú odpoveď, chvíľu sme spolu s kolegami zvažovali, o aký typ poškodenia by mohlo ísť. Na základe priloženej fotografie to nie je úplne jednoznačné (do úvahy prichádzajú rôzne dôvody - výživa, hubový patogén v pôde napr. rodu Armillaria a pod). Najpravdepodobnejšou príčinou sanám  však javí výskyt roztoča smrekového (Oligonychus ununguis), ktorý spôsobuje podobné príznaky – žltnutie a hnednutie ihlíc, neskôr ich opadávanie. Na jeho potlačenie je potrebné použiť akaricídny prípravok (nie klasický insekticíd - nie je to hmyz). Odporúčame prvú aplikáciu vykonať už začiatkom apríla, keď sa začínajú liahnúť mladé roztoče, a následne 2–3 opakovania v trojtýždňových intervaloch. Použiť môžete bežne dostupné prípravky proti roztočom. Poradia vám v najbližších predajniach so záhradníckymi potrebami. Pri aplikácii je vhodné použiť hornú hranicu odporúčanej koncentrácie, keďže ide o okrasný ihličnan, nie potravinovú plodinu. Ak by sa poškodenie po týchto zásahoch nezlepšilo, mohlo by ísť o iný, zložitejší problém – v tom prípade by bolo vhodné odobrať vzorky a vykonať laboratórne analýzy. To by už ale nebolo zdarma a tak si myslím, že v tom prípade by už bolo potom lacnejšou alternatívou výmena stromčeka za iný. Prajem vám príjemný deň,Milan Zúbrik
