Abstract | Intercept traps are used extensively to survey forest Coleoptera. A recent meta-analysis reported a significant amount of heterogeneity in the effect of trap type on flying forest Coleoptera. Much of this heterogeneity can be attributed to species-specific differences in responses to predictor variables. We tested the ability of morphological traits to explain why the effectiveness of flight-intercept trap design varies among beetle species by including nine morphological traits as moderators in meta-analysis models. Traits were selected based on hypotheses relating to beetle movement, manoeuvrability, and sensory perception, while closely correlated traits were omitted. We compared the performance of morphological traits as moderators, versus guild, taxonomic family, and null models. Morphological traits improved model fit, reduced within-study variance, and explained more variation for the effect of trap type on beetle capture rates, compared with null, guild, and taxonomic family models. Trap type effects could be due to differences in i) trap active space; ii) the proportion of beetles that initiate upwind flight and contact the trap; iii) the proportion of beetles that contact the trap surface and are captured; and iv) retention of captured individuals. Therefore, we observed the approach of large woodborers (Monochamus spp.) to pheromone-baited traps in the field. Most beetles oriented upwind to traps and we saw no differences in the number of beetles approaching to within 5 m downwind of panel and multiple-funnel traps or in the proportion of beetles orienting from 5 to 1 m downwind of traps. A significantly higher proportion of those beetles that oriented to 1 m downwind were captured by panel traps than by multiple-funnel traps. These studies suggest that morphological traits can be a valuable tool for understanding species-specific differences in trap type effects and that these differences are due to mechanisms active in the near field of traps. |
