kazakhstan - Opis:
- The research was carried out in the economic and natural Forest Reserve ‘Yertys Ormany’ in Pavlodarsk Oblast (Kazakhstan) in 2018. In the middle of May, two barrier traps of the ‘Netocia’ type (30, in total) were installed on each research plot damaged by wind, fire and great pine web – spinning pine sawfly – Acantholyda posticalis Mats. Insects were caught every month, from mid−June to mid−August. 1521 insects belonging to 67 species and 23 families were caught in the traps. Beetles clearly dominated. We also observed a great pine web and sirex woodwasp Sirex noctilio Fabr. Of the beetles caught, 10% were thermophilic jewel beetles or metallic wood−boring beetles Buprestidae, among which Chalcophora mariana (L.) dominated. The highest average number of individuals was observed on sites damaged by A. posticalis, however, differences between the plots turned to be insignificant. The highest significant average number of species was observed on sites damaged by the fire and by the wind. The GLM analysis indicated the highest mean values of the Margalef index in plots damaged by fire and by the wind, but did not show significant differences between the average values of the fidelity index of the assemblages. The research confirmed the hypothesis of a greater number of species and individuals, and a higher diversity of pests in pine stands more strongly disturbed (i.e. damaged by the fire and by the wind). At the same time, there were no differences between the most seriously disturbed variants.
