Abstract

To confirm the difference in aggregation pheromone levels in Riptortus pedestris depending on host plants, R. pedestris was measured after feeding 6 legumes: mung bean [Vigna radiata var. radiata (L.) R. Wilczek], small black bean (Rhynchosia nulubilis), hairy vetch (Vicia villosa Roth), yellow soybean [Glycine max (L.) Merr.], cranberry bean (Phaseotus vulgaris), and black soybean [Glycine max (L.)]. For the R. pedestris collected at bean fields, hairy vetch field, and outdoor field, the pheromones were also analyzed using gas chromatography. We focused on tetradecyl isobutyrate (TI) which is a known insect attractant. The bugs provided with cranberry beans secreted the most TI and those provided with hairy vetch secreted the least TI; the amount of TI secreted was different for each of the beans. The bean bugs' TI secretion percentage was the highest for those that ingested black soybean and lowest for those that ingested hairy vetch. Aggregation pheromone secretions were affected by food sources; with cases of supporting plants displaying the lowest amount of secretion, whereas cases of supporting plants and seeds displayed the highest amount of secretion as well as the highest percentage of secreting bean bugs. Bean bugs captured in bean fields secreted the highest amount of TI component.
