Question

One can see the little larva if we cut the galle in the middle

Answer

Dear Marie, thank you for your inquiry. This is a gall caused by the small hymenopteran species Andricus quercuscalicis, known as the Knopper gall. The female of this small wasp lays eggs on the acorn cup in May, injecting a special liquid inside. As a result, the oak forms a specific neoplasm — a very irregular, approximately 2 cm long, green lump (gall) — in which the larva develops. The gall seems to overgrow the acorn cup and sometimes even absorbs the entire acorn. This prevents the acorn from developing normally and causes it to lose its ability to germinate. It can damage up to 70-80% of the harvest in localized areas. Damaged acorns fall off prematurely. With best regards, M. Zubrik

Škodca bol jak na Višniach, Moruši ale aj Jabloni.

Answer

Dobrý deň, ďakujeme za dotaz. Je to spriadač americký, Hyphantria cunea. Pomerne bežný škodca na ovocných stromoch. Odporúčame vetvy s húsenicami odstrihnúť a spáliť. Pri veľmi intenzívnom napadnutí býva účinná aplikácia insekticídov. S pozdravom M. Zúbrik

Question

white foam an trunk and branches. needles dry out fall.

Answer

Hello, thank you for your inquiry. It is an aphid – Pineus strobi, the pine bark adelgid.Most individuals overwinter on the bark, where in spring they begin to produce large quantities of cotton-like masses. These cover and protect the larvae from external influences. Eggs are also laid under the cotton, from which individuals hatch and move to young shoots, with some remaining on the trunk. During its occurrence, the pines appear as if they are dusted with lime. In some areas, it is abundant, and its feeding can significantly weaken the trees. Best regards, M. Zúbrik
