DescriptionFor roughly 200 years it was assumed that trap trees attracted the bark beetle Ips typographus by means of specific chemical compounds produced by the tree. After the aggregation pheromone was discovered, the importance of tree volatiles was at first more or less totally denied (Vité 1980). Since Johann succeeded in proving that the combination of pheromone plus tree is, at times, considerably more attractive than the combination of Pheroprax plus plastic trap (Bombosch et al. 1982, Johann 1986a, 1986b), more attention has been paid to the tree even by pheromone supporters (Bakke 1985, Vité and Franke 1985). What follows is a brief synopsis of the findings thus far obtained on this question at our institute.
