Question

Answer

Thank you for your interesting inquiry and the lovely photograph. It’s unfortunate that the leaf is dead (an autumn aspect), making the damage less visible. It strongly resembles the mite Aceria nervisequa faginea, but since I am not completely certain, I would place this in the category of ambiguously identified species. If this were in summer and the photo included the underside of the leaf, identification would be clearer. Thank you once again.With best regards M. Zubrik

Question

Answer

Hello, thank you for your interesting inquiry. Such small holes are usually caused by small beetles that consume plant tissues to allow their reproductive organs to mature, a process known as maturation feeding. From these symptoms alone, it is not possible to determine the exact species involved. The most likely candidates are Chrysomela vigintipunctata or Lochmaea caprea, as these species are probably the most common in your area. With best regards M. Zubrik

Question

Answer

Hello, thank you for your interesting inquiry. There is a gall on the leaf stalk. It is not fully intact, so an exact identification of the cause is challenging. Many gall-forming species inhabit poplar leaves. It could be Contarinia petioli if it is on an aspen poplar (which cannot be determined from the image). A similar gall can also be found on poplars, caused by Pemphigus spyrothecae, and it cannot be entirely ruled out. However, I lean more towards C. petioli. Best regards M. Zubrik

Question

Holes in leaves

Answer

Thank you for your inquiry. There are holes in the leaf, but there are many potential causes that could have led to this damage. It would be necessary to obtain more supplementary information. On the lower leaf, there is a gall of the species Mikiola fagi. With best regards, M. Zubrik

Question

Äter på rosenblad och vissa nävor

Answer

Thank you for your inquiry. The image shows an insect larva from the order Hymenoptera, specifically from the suborder Symphyta – commonly known as sawflies. The larvae of these species feed on rose leaves, and in Europe, several similar species inhabit rose plants. They cause defoliation, which reduces the plant vitality and aesthetic value. The image is somewhat unclear, so we cannot confidently identify the exact species. It could potentially be the larva of Endelomyia aethiops. With best regards M. Zubrik

Question

Na ihliciach sa vyskytujú biele škvrny. Nové tohtoročné prírastky zhnedli a boli odstránené (začiatok leta). Borovica mala dlhodobo (niekoľko rokov) korene vo vlhkom prostredí (netkaná textília). Fólia je už niekoľko mesiacov odstránená, ale biele škvrny pretrvávajú.

Answer

Dobrý deň, ďakujeme za dotaz. Na ihliciach je patrná prítomnosť dvoch druhov škodcov, ktoré zásadne znižujú vitalitu stromu. Deje sa tak ale zrejme aj v kombinácii s nevhodným stanovišťom. Borovica je sĺnna drevina, ktorá ma rada priame slnko. Z obrázkov nie je jasné celková expozícia lokality, ale blízkosť domu môže zvyšovať riziko vyššej vlhkosti a menšieho oslnenia, čo borovici neprospieva. Zo škodcov na ihliciach je vidieť prítomnosť druhu štítnička borovicová, Leucaspis pusilla a napadnutie hubou najpravdepodobnejšie sypavkou borovicovou Lophodermium pinastri. S pozdravom M. Zúbrik

Answer

Dobrý deň pán Mesiarkin, jedná sa o napadnutie "červenou sypavkou borovíc", podrobnejšie informácie nájdete na našej stránke https://www.skodcoviadrevin.sk/ . Naapdnuté ihličie odporúčam na jeseň odtrániť a spáliť, alebo dať do komunálneho odpadu, rozhodne ho nekompostujte, alebo nenechávajte v záhrade. S pozdravom Roman Leontovyč
