Figure 1 in A Damage-Limiting Method for Extracting Bark and Ambrosia Beetles (Coleoptera: Curculionidae: Scolytinae) from Their Tunnels in Host Plants of Conservation Concern

Figure 1. Use of sticky cockroach traps to extract the Hawaiian endemic bark beetle Xyleborus mauiensis Perkins, 1900, from a Hawaiian endemic olapa (Cheirodendron trigynum) tree on the island of Lanai. a: Section of sticky trap ready for action; note the glue pushed to one side of the strip to form a globule; b: Beetle stuck to the glue and extracted from the wood.

Fig. 5. Ordination plot for principal components 1 and 2 in Evaluating sexual dimorphism in the ambrosia beetle Xyleborus affinis (Coleoptera: Curculionidae) using geometric morphometrics

Fig. 5. Ordination plot for principal components 1 and 2 representing elytra shape variation between sexes of Xyleborus Affinis: deformation grids describing variation between sexes on the 2 first principal components are presented.

Fig. 4 in Evaluating sexual dimorphism in the ambrosia beetle Xyleborus affinis (Coleoptera: Curculionidae) using geometric morphometrics

Fig. 4. Boxplots for the body structure centroid size in Xyleborus affinis: (A) elytra centroid size; (B) pronotum centroid size. The line within each box represents the median, and the height of each box represents first and third quartiles (75% of all data). The lines correspond to the observed minimum and maximum values and dots are outliers

Fig. 1. Configuration of landmarks and semi-landmarks used to register 1 side of the 2 body structures (elytra and pronotum) of Xyleborus affinis: (A) configuration of 3 landmarks (1, 9, 10) and 7 semi-landmarks (2–8) describing elytra shape; (B) configuration of 3 landmarks (1, 2, 8) and 5 semi-landmarks (3–7) describing pronotum shape.
