“…The bean bug, Riptortus pedestris (Fabricius) (Hemiptera: Alydidae) is a polyphagous and one of the most important pests in Asian countries including South Korea, Japan, India and China (Kono 1989; Leal et al 1995; Li et al 2019; Lim 2013; Visalakshi et al 1976). Both adults and nymphs of R. pedestris feed on leguminous plants, especially soybeans.…”

“…They attack the soybean pod and seed by piercing and sucking, resulting in serious economic losses. It has been reported that the bean bug is the major insect pest responsible for staygreen syndrome, which is characterized by a lack of timely leaf senescence and an increase in seed abortion, in Chinese soybean fields (Li et al 2019). Many published studies have demonstrated the effects of temperature on demographic characteristics and population parameters of R. pedestris (Ahn et al 2019; Kim et al 2009; Rahman & Lim 2017).…”

We evaluated the direct effects of three different CO2 concentrations (400, 600 and 1,000 ppm) on the population parameters and growth of the bean bug, Riptortus pedestris, while being fed on soybean. The raw life history data from R. pedestris was analyzed using an age‐stage, two‐sex life table to take the viable development rate among individuals into account. Based on the age‐stage, two‐sex life table analysis, the population projections of R. pedestris provide the stage structure and variability of the population growth under different CO2 treatments. Our results showed significantly shorter immature durations and higher pre‐adult survival rate under elevated CO2 (1,000 ppm) than those under ambient CO2 (400 ppm). The population of R. pedestris reared under elevated CO2 conditions showed higher intrinsic and finite rates of increase but a lower mean generation time than R. pedestris reared under ambient CO2 conditions. Our results show the population parameters and growth of R. pedestris are influenced by increased CO2 relative to ambient CO2 treatment. Further studies on the long‐term direct effects of different CO2 levels on R. pedestris are essential to understand their population dynamics and to establish appropriate management strategies.

“…The pods of soybeans drop or shrivel after suffering R. pedestris injury, and the transportation of nutrients is affected in damaged plants, resulting in “Staygreen Syndrome” [ 10 , 11 ]. Besides the above mentioned direct damage, R. pedestris, as a vector, disseminates yeast-spot disease [ 12 ], which often leads to the complete abortion of seeds in the whole field [ 13 ].…”

The bean bug, Riptortus pedestris, is a major pest of soybeans. In order to assess the critical stages of soybean damage by R. pedestris, we tested the damage to soybeans at different growth stages (R2, R4, and R6) caused by five densities of R. pedestris (1, 2, 3, 4, and 5) through a field cage experiment. The results show that the R4 stage was the most sensitive stage in terms of suffering R. pedestris injury damage, followed by the R6 stage and then the R2 stage. The number of stay green leaves was 7.04 per plant, the abortive pod rate of the soybeans was 56.36%, and the abortive seed rate of the soybeans was 46.69%. The dry weight of the soybeans was 14.20 g at the R4 stage; these values of R4 were significantly higher than at the R2 and R6 stages. However, the dry weight of soybean seed was 4.27 g and the nutrient transfer rate was 27.01% in the R4 stage; these values were significantly lower than in the R2 and R6 stages. The number of stay green leaves, abortive pod rates, and abortive seed rates were all increased significantly with increasing pest density at each stage of soybean growth. However, the nutrient transfer rate was significantly decreased with the increase in the pest density. Soybean nutrition factors changed after they suffered R. pedestris injury; the lipid content of the soybean seed decreased and the lipid content of the soybean plant increased compared to controls, when tested with a density of five R. pedestris in the R4 stage. These results will be beneficial to the future management of R. pedestris in soybean fields.

“…Both adults and nymphs of R. pedestris feed on leguminous plants or fruit trees, such as kidney bean ( Phaseolus vulgaris L.) and apple ( Malus pumila Miller), and transmit viruses or microorganisms, causing an increasing number of empty pods and undeveloped seeds based on the developmental stage and density of the insects [ 2 ]. In recent years, an increasing number of scientists have investigated the potential of this pest to cause damage to soybean in China, especially in the summer growing season from August to September [ 3 ]. However, there are many challenges to controlling the growth and development of R. pedestris .…”

Riptortus pedestris (Hemiptera: Alydidae) is a major agricultural pest in East Asia that causes considerable economic losses to the soybean crop each year. However, the molecular mechanisms governing the growth and development of R. pedestris have not been fully elucidated. In this study, the Illumina HiSeq6000 platform was employed to perform de novo transcriptome assembly and determine the gene expression profiles of this species across all developmental stages, including eggs, first-, second-, third-, fourth-, and fifth-instar nymphs, and adults. In this study, a total of 60,058 unigenes were assembled from numerous raw reads, exhibiting an N50 length of 2126 bp and an average length of 1199 bp, and the unigenes were annotated and classified with various databases, such as the Kyoto Encyclopedia of Genes and Genomes (KEGG), Clusters of Orthologous Groups (COG), and Gene Ontology (GO). Furthermore, various numbers of differentially expressed genes (DEGs) were calculated through pairwise comparisons of all life stages, and some of these DEGs were associated with immunity, metabolism, and development by GO and KEGG enrichment. In addition, 35,158 simple sequence repeats (SSRs) and 715,604 potential single nucleotide polymorphisms (SNPs) were identified from the seven transcriptome libraries of R. pedestris. Finally, we identified and summarized ten wing formation-related signaling pathways, and the molecular properties and expression levels of five wing development-related genes were analyzed using quantitative real-time PCR for all developmental stages of R. pedestris. Taken together, the results of this study may establish a foundation for future research investigating developmental processes and wing formation in hemimetabolous insects and may provide valuable data for pest control efforts attempting to reduce the economic damage caused by this pest.
