Trypodendron

Trypodendron

 

a genus of beetles of the family Scolytidae. They have a bare and glossy cylindrical body, 2.8-3.8 mm long and with a protruding pronotum; they are black and their wing cases usually have stripes. The beetles live in wood, in which they bore passages. The legless, soft, S-shaped larvae feed on the hyphae of the ambrosia fungus, which beetles bring to the passages. There are nine species in the USSR, including the lineate bask-beetle (T. lineatus), which damages conifers, the oak pinhole borer (T. domesticus), which damages oak and sometimes other deciduous trees, and T. signatus, which attacks various deciduous species.

In a mark-recapture study, the striped ambrosia beetle, Trypodendron lineatum (Olivier) (Coleoptera: Curculionidae), which is a coniferous forest tree pest in the western United States, only exhibited non-directed flight for distances of 100 m or more, whereas recaptures at 500 m were primarily downwind of the release point (Salom & McLean 1989).
A related curculionid species, Trypodendron lineatum (Olivier), was able to com plete upwind oriented flights to baited traps at distances of up to 25 m, but beyond this distance the flights were largely downwind and undirected (Salom & McLean 1989).
