“…The bean bug, Riptortus pedestris (Fabricius; Hemiptera: Heteroptera), is one of the major pests threatening soybeans and is widely distributed in Asia, including South Korea, Japan, India, and China (Son et al ., 2000; J. Li et al ., 2019; K. Li et al ., 2019; Huang et al ., 2021; H. Zhang et al ., 2022; Y. Zhang et al ., 2022). Riptortus pedestris goes through five nymphal stages and has two or three generations per year (Huh et al ., 2005; Song et al ., 2022). Both nymphs and adults obtain nutrients and water by inserting their sucking mouthparts directly into leaves, stems, flowers, pods, and seeds, resulting in significant yield losses and low seed quality (Bae et al ., 2014; Rahman & Lim, 2017).…”

Transcriptional profiling reveals a critical role of GmFT2a in soybean staygreen syndrome caused by the pest Riptortus pedestris

et al. 2022

Soybean staygreen syndrome, characterized by delayed leaf and stem senescence, abnormal pods, and aborted seeds, has recently become a serious and prominent problem in soybean production. Although the pest Riptortus pedestris has received increasing attention as the possible cause of staygreen syndrome, the mechanism remains unknown.Here, we clarify that direct feeding by R. pedestris, not transmission of a pathogen by this pest, is the primary cause of typical soybean staygreen syndrome and that critical feeding damage occurs at the early pod stage.Transcriptome profiling of soybean indicated that many signal transduction pathways, including photoperiod, hormone, defense response, and photosynthesis, respond to R. pedestris infestation. Importantly, we discovered that members of the FLOWERING LOCUS T (FT) gene family were suppressed by R. pedestris infestation, and overexpression of floral inducer GmFT2a attenuates staygreen symptoms by mediating soybean defense response and photosynthesis.Together, our findings systematically illustrate the association between pest infestation and soybean staygreen syndrome and provide the basis for establishing a targeted soybean pest prevention and control system.

Hemipteran bugs, which were previously considered as secondary pests, have currently become important pests of numerous crops. Among them, Riptortus pedestris (Fabricius) is a major species that occurs in Korea, Japan, China, and South Asian countries. Riptortus pedestris infests leguminous crops like soybean, vetches, and red clover; fruit trees like persimmon and yuju; and grains like barley, foxtail millet, broomcorn, and sorghum. Riptortus pedestris causes the greatest damage to soybean, as it is the most suitable host for the bug. Feeding damage during pod formation significantly reduces the yield of soybean. Currently, 17 insecticides, including diazinon and etofenprox, are registered for the control of hemipteran bugs in Korea, and growers apply insecticides two to three times on a regular basis. Aggregation pheromone traps are widely used as a monitoring tool and partial control measure. The aggregation pheromone of R. pedestris attracts conspecific adults and nymphs and is used for food exploitation rather than sexual attraction. In addition, the pheromone serves as a kairomone for egg parasitoids such as Gryon japonicum (Ashmead) and Ooencyrtus nezarae Ishii. As a new method of pest management, nonviable host eggs were included in the pheromone trap to catch R. pedestris and propagate parasitoids. As a part of cultural practices, resistant soybean varieties with specific color and size of pod and control of flowering time through the alteration of planting date can be used. For the effective management of R. pedestris in the near future, development of cultural practices that can support natural control factors and the use of multiple control tactics are needed.

“…The increased attraction of adult bugs to the aggregation pheromone traps in autumn can be explained by our previous study in which female bugs in reproductive diapause are more responsive to aggregation pheromone. 38 It has been found that male R. pedestris do not produce aggregation pheromone once they enter reproductive diapause, 9,39 potentially reducing competition between naturally occurring adults and traps. Diapause in adult R. pedestris is induced by short photoperiods, with a critical day length of 13.5 h at 25 ∘ C. 40 In Andong, where these experiments were conducted, the day length became shorter than 13.5 h from mid-August in both years.…”
