LAZARO-DZUL, Martha Olivia et al. Monitoring of Scolytinae (Coleoptera: Curculionidae) with handmade traps baited with different attractants in Tamaulipas, Mexico. Acta Zool. Mex [online]. 2025, vol.41, e2757.  Epub 10-Out-2025. ISSN 2448-8445.  https://doi.org/10.21829/azm.2025.4112757.

This study aimed to determine the efficiency of four handmade traps with attractants for capturing Scolytinae in the "Laguna del Carpintero", Tampico, Tamaulipas. The traps were made with 1, 1.5, and 2.5 L PET bottles, placed 1.5 m from the ground and separated by 20 m. The attractants used were ethanol, methanol, ethanol + methanol, and apple cider vinegar + ethanol. For data analysis, a correspondence analysis was used to evaluate capture frequencies and treatments (trap type + attractant); in addition, a descriptive analysis was performed to calculate the total, minimum, maximum, and average number of individuals captured per species, as well as the capture percentage according to the trap and attractant design. A total of 408 specimens were collected, and four genera and 10 species of Scolytinae were identified, Hypothenemus, Coccotrypes, Microcorthylus, and Xyleborus; the first with seven species, while the other three with one species each. Hypothenemus birmanus (Eichhoff, 1878) with 237 specimens was the most abundant, on the contrary, Coccotrypes cyperi (Beeson, 1929) the least abundant with one specimen. Coccotrypes cyperi, Hypothenemus eruditus and Hypothenemus obscurus represent new records for Tamaulipas. Trap number 4 captured the highest number of individuals (200), while the capture frequency of each species was significantly associated with the treatments evaluated, the attractants ethanol + methanol and apple cider vinegar + ethanol were the most effective, with 109 and 123 captures, respectively. These results suggest that handmade traps represent an efficient alternative for collecting Scolytinae in mangrove ecosystems.
