Abstract
The generally accepted assumption on the low mortality pressure for inside-tree habitat was challenged in this study. To achieve this objective, the number of larval instars of xylem-feeding Aredolpona rubra (L.) (Coleoptera: Cerambycidae) was determined using multidimensional statistics, and the life table was constructed based on the head-width distribution of larvae taken from the field. The mean value of natural mortality of an average larva was then compared with data available for other wood-feeding species and contrasted with insects from other feeding guilds. The results show that larvae living in wood experience lower mortality rates than those from other habitats and that, among the wood-feeders, the mortality rate of larvae decreases while development time increases further inside the tree.
