MACIAS-SAMANO, Jorge Enrique; RIVERA-GRANADOS, Martha Laura; JONES, Robert  and  IBARRA, Guillermo. Response of bark beetles and their predators to semiochemicals in southeast Mexico. Madera bosques [online]. 2014, vol.20, n.3, pp.41-47. ISSN 2448-7597.

Field responses to multiple-funnel traps baited with commercial α-pinene plus either frontalin, ipsenol or ipsdienol were recorded for bark beetles and their associates in southern Mexico. Dendroctonus frontalis Zimmermann (Coleoptera: Curculionidae, Scolytinae) was attracted only to frontalin plus α-pineno. Ips grandicollis (Eichhoff) (Coleoptera: Curculionidae, Scolytinae), Enoclerus ablusus Barr (Coleoptera: Cleridae) and Elacatis sp. (Pascoe) (Coleoptera: Salpingidae) were attracted to both combinations of ipsenol and ipsdienol plus α-pineno, Temnochila chlorodia Mannerheim (Coleoptera: Trogositidae) responded to all treatments. Tenebroides corticalis (Melsheimer) (Coleoptera: Trogositidae) and Temnochila virescens (F.) were also captured in small numbers. From these results, the predator T. chlorodia tuned to semiochemicals known to be produced by either D. frontalis or I. grandicollis species, whereas the predators E. ablusus and Elacatis sp were attracted exclusively to semiochemicals known to be produced by Ips species. Differences in response are discussed in the light of similar works, stressing the variations found between bark beetle-predator guilds and semiochemical response from North American and South Mexico.
