Figure 3 in Effects of Ultraviolet Light and Pheromone Release Rate in Trapping Coconut Rhinoceros Beetles, Oryctes rhinoceros (Coleoptera: Scarabaeidae), on Guam

Figure 3. Capture rates (mean ± SE) of beetle caught in double-vaned bucket. UV = trap equipped with UV LED diodes, RL = trap with reduced release rate of oryctalure, SL = trap with standard release rate of oryctalure. Comparisons of mean trap capture between traps with and without UV light and between traps with different oryctalure release rates are shown at right. Bars with different letters indicate significantly different means (UV light: t-test, Lure: ANOVA, Tukey's HSD).
