 'Bait' trees were selected and felled.
(Jiri Hulcr) |
 Bait trees were burned to increase attractiveness to bark and ambrosia beetles (Coleoptera: Curculionidae: Scolytinae and Platypodinae) and were left in situ for one month. |
 Beetles bored in to the felled tree creating tunnels and cultivated a fungal garden on which they and their larvae feed. Note the sawdust created by these beetles on the bark. |
 Trees were cut into 3 -1m sections (trunk, branches, twigs) and brought back to the station. |
 Gallery entrances were marked and the sections were cut into 2-4'' diameter "cookies" that each received a number corresponding to the tree from which it was obtained. |
 'Sawed' Camptocerus gallery. The male stays in the entrance, while the female is found at the ends of one the branching arms of the gallery |
 The beetles are very difficult to remove from their gallery because they tend to go to the end of one of the radial arms. Part of the wood near the gallery is removed with the aid of a chisel. (Panama) |
 When a chiseled piece of wood contains a beetle, it is clipped out using pruning shears. (Panama) |
 The final result is a pile of toothpick sized pieces of wood. |
