- Abstract
Scolytines are widely distributed and function to contribute to the balance of natural ecosystems by participating in decomposition of plant organic matter. However, some species with ambrosial habits now are relevant for avocado crops because they are vectors of phytopathogenic fungi. To determine attraction response of Scolytinae individuals to chemical attractants, we evaluated alpha-copaene, querciverol, alpha-copaene + querciverol, and ethanol in eight-funnel Lindgren-type intersection traps. A negative binomial regression test showed significant effect on captures of Scolytinae in response to different treatments (P < 0.001). Ethanol and the alpha-copaene + querciverol combination were more attractive mostly to species with ambrosial habits. The most abundant species of ambrosia beetles were Corthylus flagellifer Bladford, Corthylus luridus Blandford, Xyleborus volvulus Fabricius, and Corthylus detrimentosus Schedl that responded significantly to both treatments. To use preventive measures against beetles that are vectors of phytopathogenic fungi in avocado orchards, we suggest frequent monitoring using traps baited with ethanol or commercial attractants with alpha-copaene + querciverol.
