Age-related and Individual Variation in Male Piezodorus hybneri (Heteroptera: Pentatomidae) Pheromones

Figure 1

Daily changes in pheromone emission and the proportion of β-sesquiphellandrene from individual males of Piezodorus hybneri. The bar shows the total amount of pheromone (μg/male/day). The line chart indicates the proportion of β-sesquiphellandrene (%) among the total pheromone components. Inverted triangle indicates the day when the bugs died. Because male No. 6 did not emit any pheromone, there was no data available in this figure.
