Description
| - Na souboru stromů byly provedeny infekční pokusy s imagy lýkožrouta smrkového Ips typographus L. původem ze Šumavy a Školního lesního podniku Křtiny. U stejného souboru brouků byla kvalitativně zjišťována povrchová mykoflóra. Cílem zpětných izolací bylo zjistit, zda druhy nalezené na povrchu imag Ips typographus se po inokulaci šíří i hostitelskými pletivy. V okolí inokulace imagy Ips typographus jsou patrny výrazné nekrotické zóny včetně symptomů pronikání vaskulárních patogenů lýkem i bělí. Nejvýraznější reakce byly pozorovány v případě inokulace neošetřeným imagem lýkožrouta smrkového (Ips typographus). Ošetření imag lýkožrouta smrkového přípravky Ibefungin a Fundazol nemělo v plném rozsahu očekávaný efekt. Na povrchu těl brouků byly pozorovány spory potenciálně patogenní houby Ceratocystis polonica (Siem.) C. Moreau, která byla zjištěna i ze zpětných izolací z pletiv okolí umělých infekcí lýkožroutem smrkovým. Zde byly zjištěny i některé další druhy jako Ophiostoma bicolor Davidson & Wells, Leptog (cs)
- Inoculation experiments were carried out on a set of trees with imagoes of Ips typographus L. which origin from the Šumava Mts. and the Křtiny Training Enterprise. The objective of back inoculations was to determine whether species found on the surface of Ips typographus imagoes spread after the inoculation also through host tissues. It the vicinity of inoculation by Ips typographus imagoes, marked necrotic zones are evident including symptoms of the penetration of vascular pathogens through phloem and sapwood. The most marked reactions were observed in case of inoculation by an untreated Ips typographus imago. Treatment of Ips typographus imagoes by Ibefungin and Fundazol preparations did not demonstrate expected effects in full scale. The spores of several ophiostomoid fungi like Ceratocystis polonica (Siem.) C. Moreau were observed on the surface of bark beetles and at the same time were reisolated from wounds inoculated by Ips typographus imagoes. The other fungi like Ophiostoma bicolor Davidson &
