Abstract
Mass outbreak of the leaf weevil Phyllobius arborator affected two- to six-year beech plantations to the greatest extent, and caused serious damage to self-seeded European mountain ash trees in young spruce plantations and in premature spruce stands. Beetles were flitting from early June to mid-August and/or to late September under the given natural conditions, while the most intensive swarming was observed in late June and in early July. Females are laying first eggs after a week of maturation feeding. They laid them on the leaves of host plants, making a single-layer group with the average number of 30 eggs. Other eggs are laid after regeneration feeding. Potential fertility of females is 138 eggs, real fertility is about 100 eggs. Males live for about four weeks and females for about three weeks. They produce about three groups of eggs during their short lifetime. Eggs drop off the leaves onto the ground soon, where larvae emerge in two to three weeks undergoing their evolution on the roots. Beetles, and especially larvae, are widely polyphagous.
