Abstract:

In this poster will present the infection degree of pine processionary caterpillar in Austrian pine forest of Albania during cycle 2016 – 2017 . The infestation degree is studied in stands with Austrian pine (Pinus nigra Arnold) and concretely in teen Districts as Puka, Shkodra, Tropoja, Vlora, Berati, Elbasani, Librazhdi, Pogradeci, Korça and Kolonja. The methodology applied consist in taking of 5 surfaces samples, each of them 2500 m2 for each pine stand. In every sample are settled 30 control trees, in total 150 trees for stand. In these 150 control trees are made observation about number of nests for each control tree. In this way the pine processionary infection degree is given with number of nests for tree and is presented more high in Districts of Puka (objects of Gomsiqe, Luf and Puka) with infection degree on the average of 3-4 nests / tree; Tropoja (objects of Rragam and Tropoja) with infection degree of 3 nests /tree.; Berati (objects of Karkanjoz, Bregu i Frengut and Tomorr) with infection degree of 8-9 nests /tree; Elbasan ( object of Gjinar) with infection degree on the average of 2.5 nests /tree; Pogradec (object of Guri i kuq-Lin) with infection degree on the average 3.5 nests/tree; Korça ( object of Morava ) with infection degree on the average of 2.5 nests/tree. Based on the above results in objects with high infection degree of pine processionary caterpillar has been necessary the intervention with control measures (treatments with bio-preparation Bacillus thuringiensis var.kurstaki).

Keywords: Pine processionary caterpillar; infection degree; Pinus nigra, stands; number of nests/tree.
