SUMMARY: A health evaluation in 1993 of the five Austrian pine plantations in the Crikvenica-Vinodol region (Fig. 1.) has revealed mainly dieback of one- and two-year old shoots from the different part of crowns. In four plantations (Pališin, Vinište, Ravna strana and Ruševo) the dieback was less frequently present, but in Klenovica it has been observed with more frequent presentation. Young pines, near the sea, were more injured than other pines in the Klenovica plantation (Fig. 2.). Field observation of the mentioned five plantations showed the low frequency presence of pine processionary moth (Cnethocampa pytiocampa Schiff). Laboratory analyses of the collected samples (needles, shoots, branches and cones) showed occurrence of some mycoses and insects: Sphaeropsis sapinea (Fr.) Dyko et Sutton (Fig. 3.), Cyclaneusma niveum (Fr.) DiCosmo, Peredo et Minter, Lophodermium seditiosum Minter, Staley et Millar, Cenangium ferruginosum Fr. and Truncatella hartigii (Tub.) Stay.; Ernobius sp., Blastophagus minor Htg. (Fig. 4.) and Leucaspis sp. Among them Sphaeropsis sapinea and Ernobius sp. were the most frequent and also with significant injurious impact on the dieback of one- and two-year old pine shoots. The analysis showed that some of the shoots were attacked by Sphaeropsis sapinea, some by Ernobius sp., and some shoots both by Sphaeropsis sapinea and Ernobius sp. It has not been established if there was or was not any connection in occurrence of the mycosis and insect. Key words: Austrian pine, mycoses, insect pests, Crikvenica -Vinodol area, Croatia. |
