M. Campos et A. Pena, RESPONSE OF PHLOEOTRIBUS-SCARABAEOIDES (COLEOPTERA, SCOLYTIDAE) TO ETHYLENE IN AN OLFACTOMETER, Experientia, 51(1), 1995, pp. 77-79
The role of ethylene, pure or in formulation, in the colonization beha
viour of the olive bark beetle, Phloeotribus scarabaeoides (Coleoptera
, Scolytidae) has been investigated in the laboratory. Ethylene has be
en found to be attractive in both sexes; the formulation ethrel 48 was
active in an olfactometer up to several months. Ethylene, whose conce
ntration varies with the developmental stage or the condition of the t
ree or its wood, may play an important role in the primary attraction
of these scolytids to their host.
