Seed Pests and their Impact on Reforestation Efforts in Croatia     pdf     HR     EN 101
Summary: Seed pests can significantly lessen natural regeneration and hamper silvicultural reforestation practices in modern forestry. The most important pests are highly specialized forest insects that thrive on tree seed crops. Our research focused on seed pests of the most important forest tree species in Croatia. Surveys were made in typical forest communities including lowland oak forests, mixed fir and beech stands and the Mediterranean belt of holm oak forest. Major research emphasis was on acorn pests from lowland forests of pedunculate oak, Quercus robur.

Losses of acorn crops due to seminiphagous insects ranged from 4 to 25. In some areas small rodents were equally important, causing acorn losses up to 18. Four species of acorn weevils were identified. The most numerous was Curculio glandium Marsh. Extensive ground surveys for buried larvae revealed their spatial distribution and provided details of their biology. Field trials were used to evaluate protection measures for applied control. The entomopathogenic fungus Metarrhizium anisopliae (Mitach.) Sor., was the most consistent natural suppression agent throughout the study area. Soil dwelling larvae of Curculio species were killed by this widely distributed fungus, which often reduced their populations to non-pest levels. Other acorn pests included Cydia splendana Hb., C. amplana Hb. and Andricus quercus calicis Burgs.

Conifer cones and seed were attacked by several species of conophagous and seminiphagous insects: Dioryctria abietella Den. et Schiff., Barbara herrichiana Obr., Megastigmus suspectus Borr., Earomyia impossibile Morge and Resseliella piceae Seit. on common silver fir; Ernobius abietis Fabr., Laspeyresia strobillela L. on common spruce, and C. strobilella and Pissodes validirostris Gyll. on Austrian pine cones.

Further investigation on the biology, potential of biological control and the effects of crop size are continuing for these seed pests.
