Attractiveness of Stink Bugs to Color, Height and Location of Aggregation Pheromone Trap

Use of aggregation pheromone traps increases infestation of adult Riptortus pedestris (Hemiptera: Alydidae) in soybean fields

“…For most of the growing season, bug numbers caught in aggregation pheromone traps were lower than the counted bug in plots, particularly when the counted bug population in the plots was high. Aggregation pheromone traps caught 34 ± 3.2 to 98 ± 63.5 bugs/trap/10–13 days during the peak attraction period in both experimental and commercial fields; levels similar to those found in previous studies . The numbers of R. pedestris caught in aggregation pheromone traps did not correspond with concurrent density of R. pedestris in soybean fields during autumn.…”

“…Growers' complaints regarding the efficacy of using the traps alone led us to conduct this study. Few studies have investigated reducing R. pedestris populations using aggregation pheromone traps in soybean fields, even though many studies have assessed the trapping efficiency of different types and colors of traps used with aggregation pheromone . Furthermore, some studies on other species have shown that higher pest populations, and thus more damage, may occur near aggregation pheromone traps in grape, soybean, and tomato, due to a phenomenon known as ‘trap spillover.’…”

“…10 Semiochemicals are used in different ways in the integrated pest management of hemipteran bugs, for example in monitoring, [10][11][12] mass-trapping, 13,14 and mating disruption. 15,16 In Korea, aggregation pheromone traps have been used in soybean fields both to monitor 17,18 and to provide control through mass-capture 13,19 of R. pedestris. The aggregation pheromone produced by adult males of R. pedestris has four components: (E)-2-hexenyl (Z)-3-hexenoate, (E)-2-hexenyl (Z)-2-hexenoate, myristyl isobutyrate, and octadecyl isobutyrate.…”

“…Few studies have investigated reducing R. pedestris populations using aggregation pheromone traps in soybean fields, 13 even though many studies have assessed the trapping efficiency of different types and colors of traps used with aggregation pheromone. 19,[24][25][26] Furthermore, some studies on other species have shown that higher pest populations, and thus more damage, may occur near aggregation pheromone traps in grape, soybean, and tomato, due to a phenomenon known as 'trap spillover.' [27][28][29] Therefore, in this study, we first assessed whether an aggregation pheromone trap can reduce the population of R. pedestris in small soybean plots by using both a before/after and a with/without design in 2013 and 2014, respectively.…”
