The mountain pine beetle reacts strongly to chemicals called pheromones that are produced by the insects during their attacks, as well as to kairomones, aromatic compounds produced by the trees, says James Powell, a mathematician from Utah State University in Logan who models the dynamics of beetle invasions in pine forests. Although this result must be interpreted with some caution because sampling was limited in scope and traps generally did not use kairomones, the virtual absence of Anopheles mosquitoes from trap catches suggests populations and hence malaria risk at KAF was low or absent. Kairomones are compounds emanating in tiny quantities from the fresh scars of trees that have been recently pruned. |
