Abstract: [Objective] Semiochemicals have the advantages such as less environmental pollution, less easy to produce drug resistance and easy to use in monitoring and controlling insect pests, which is a hot study spot in pest control field. In this study, we compared the lure effects of three botanical attractants to beetles in two forest types in order to screen effective lures for controlling various coleopterous beetles. [Method] The attractant traps were placed in a natural secondary forest (Laoshan station) and an artificial pure forest (Northeast Forestry University Forest Farm) to compare the trapping effects of the three attractants by Lindgren funnel traps. Luring effect was compared in different locations to confirm influence under different environmental factors. [Result] 1) The three botanical attractants, UHR, COB, and LAP, had different lures on beetles and trapped 3 215 coleopterous beetles belonging to 55 families and 120 genera. Among these beetles, the insects of Scolytidae were 48.93% of the total coleopterous beetles and were dominant beetles. The trap effects of three botanical attractants were in the order of UHR > COB > LAP. The UHR attractant trapped 74.21% of total attractive beetle individuals, and the Scolytidae individuals were 48.65% of these trapped beetles. The dominant species were Xyleborus dispar and Scolytoplatypus sp. in Scolytidae. 2) The UHR attractant had stronger lure to Scolytidae, Elateridae, Cleridae, Silphidae than COB and LAP attractants, while the COB attractant had stronger lure to Staphylinidae. However, there was no significant difference of the three attractants in attractive effect to Cerambycidae and Curculionidae. 3) The attractants had stronger trap effects in Laoshan station than in Northeast Forestry University Forest Farm, indicating that the chemical attractants had different efficiency in different geographical areas. Silphidae was only trapped in Laoshan station, which might be related to living habit and environment. [Conclusion] Thus, the UHR attractant have stronger lure to Scolytidae beetles and could be further developed for monitoring and controlling Scolytidae beetles in forests. This study also provides a new method for the nuisanceless prevention.
