Question

Dobrý deň,tieto hálky som našla v lese na zemi,neviem aky strom bol presne napadnuty.Po otvoreni bola v strede jedna gulicka,myslela som si,ze je to semeno nejakej rastliny. Ale po nastudovani vasej stranky sa mi to podoba na halku hrciarky andricus hungaricus....

Answer

Dobrý deň, ďakujeme za informáciu. Áno, potvrdzujeme, že sa jedná o hrčiarku Andricus hungaricus. Napáda výlučne dub, preto sa zrejme niekde v okolí musel nachádzať. Nespôsobuje obyčajne vážnejšie škody. V strede hálky žije drobná larva. Pekný deň želá MZ.

Question

Answer

Dobrý deň, fotografia nie je celkom jednoznačná- myslím, že to hálka ktorú spôsobuje na žaluďoch osička Andricus dentimitratus. Jej larva žije vo vnútri hálky. Častejšie na žaluďoch u nás spôsobuje hálky iný, príbuzný druh - Andricus quercuscalicis.  Andricus dentimitratus u nás nie je úplne bežný. Je hojnejší na juhu Európy, v Mediteránne, v Maďarsku...ale žije ako vidno aj u nás. Dokáže poškodiť väčšinu žaluďov na strome, čo môže byť problém, ak má semeno duba slúžiť na prirodzenú obnovu v následnom lese. Samotnému stromu výskyt tejto hálky neškodí. Pekný deň. MZ

Question

Je to Dendroctonus micans?

Answer

Nie, nezdá sa, že je to Dendroctonus micans. Skôr sa môže jednať o niektorý druh obaľovača, ktorý žije pod kôrou. Obaľovače zväčša žijú na listoch stromov, ale existujú aj také druhy, ktoré žijú pod kôrou stromov alebo v púčikoch. Ronenie živice môže byť sprievodný znak ich prítomnosti. Mohol by to byť napríklad obaľovač praslenový Laspeyresia pactolana ale príapdne aj nejaký iný druh. Pekný deň MZ

Question

Mám na pozemku starší dub (70r +) a po prvýkrát som u neho spozoroval takéto ochorenie až v tomto roku. Poškodené plody sú lepkavé. Na dube parazitujú 2 imelá...

Answer

Dobrý deň, je to hrčiarka kalichová Andricus quercuscalicis. Pomerne bežný druh malého blanokrídlovca, veľkého len pár milimetrov, ktorý vytvára takéto hálky na plodoch dubov. Niekedy býva tak hojná, že je schopná zničiť podstatnú časť úrody žaluďov. Nie je preto vítaná najmä v porastoch, ktoré sú potenciálnym zdrojom semenného materiálu. Pekný deň MZ

Question

Živý strom v poraste, znaky poškodenia od územku do výšky zhruba 5 m. Dĺžka prasklín 3-12 cm.

Answer

Jedná sa o staršie poškodenie kmeňa  lykožrútom bukovým. Neúspešný nálet lyožrútov na živý buk, požerky boli zaliate miazgou, strom sa ubránil. Následne, počas rastu, vznikajú na poškodenej kôre praskliny.
