Reduction of larvae in tree crowns is quite considerable and is much higher after outbreak than in the year of an outbreak. Mortality of pupae due to parasites increased in successive years following the outbreak, whereas mortality caused by non-specialized predators – decreased As the outbreak is coming to the end the reduction of the larval stage in tree crowns increased, whereas that of the pupal stage in soil - decreased.
