Wind-aided dispersal of simulated bark beetles flying through forests

Larger bark beetles such as Ips typographus (Coleoptera: Scolytidae) fly at about 2 m s for up to several hours. Computer simulations in two dimensions showed that bark beetles are capable of dispersing from a brood tree over wide areas while drifting with the wind. For example, if beetles take an angle of maximum turn (AMT) at random up to 10° either left or right each second, about 90% of the...

Chemical ecology of phytophagous scarab beetles.

Sex pheromones have been characterized only for species in the subfamilies Rutelinae and Melolonthinae; aggregation pheromones have been identified for two species in the Dynastinae. Melolonthines utilize mainly amino acid derivatives and terpenoid compounds, but sex pheromones of rutelines are fatty acid derivatives. Various other species utilize japonilure-type lactones that are produced by d...
