“…Soybean aphid had been a major pest of soybean in the Midwestern United States since 2000 (Ragsdale et al, 2011) and a major prey item of coccinellids in that crop (Fox et al, 2004;Schmidt et al, 2008). However, populations of soybean aphid have decreased substantially over the last 10-15 years in the region (Bahlai et al, 2015;Crossley et al, 2021;Hesler and Beckendorf, 2021), and this temporally corresponds to significant declines of adult coccinellids in soybeans in our study (Figure 1). Comparisons with earlier surveys of coccinellids in eastern South Dakota are not available because historically the crop lacked significant arthropod pests and robust predator populations (Ragsdale et al, 2011;Hesler, 2014).…”

Lady (= ladybird) beetles (Coleoptera: Coccinellidae) provide agroecosystem services as major predators of aphids and other pests of field crops. Several native coccinellids in North America have declined in association with the introduction of invasive species of lady beetles. In particular, populations of three native species declined drastically (Coccinella transversoguttata richardsoni) or effectively disappeared (Coccinella novemnotata, Adalia bipunctata) from agricultural landscapes in eastern South Dakota, U.S.A., following establishment of an invasive coccinellid (Coccinella septempunctata) in the 1980s. Since then, two other non-native coccinellids (Harmonia axyridis and Hippodamia variegata) have established in eastern South Dakota, but long-term analysis of their impact on the aphidophagous coccinellid guild is lacking. This paper summarizes long-term results from 14 years (2007–2020) of sampling coccinellids by sweepnet and timed searches in five field crops and restored prairie in eastern South Dakota. In all, 17,338 aphidophagous coccinellids comprising 10 species were sampled. Two invasive species (Coc. septempunctata, Har. axyridis) were the third- and fourth-most abundant species, respectively. The seven most abundant species constituted 99% of all coccinellids sampled and were recorded from all six habitats. However, coccinellid species ranged considerably in their evenness of habitat use, resulting in differences in rank abundance among habitats. Coccinellid assemblages were similar for alfalfa and winter wheat, but not for other habitats, which possessed distinct coccinellid assemblages based on rank abundance. Annual abundance of coccinellids varied considerably within habitats, but declining trends were evident from significant negative regressions in annual abundance for adult and immature coccinellids in corn and adults in soybean. As a group, native adult coccinellids showed a significant declining trend in corn but not in other habitats, whereas trends for non-native adult coccinellids were non-significant in all habitats. Sample rates of coccinellids in alfalfa, spring grains, and corn in this study were 74, 26, and 6%, respectively, compared to that of a previous study from the region, further indicating substantial decreases in coccinellid abundance. Possible explanations and implications for observed patterns in coccinellid diversity and individual species abundances in field crops and restored prairie of eastern South Dakota are discussed with respect to prey, agronomic trends, and landscape factors.

“…Pests are a limiting factor for crop production, including soybean, Glycine max (L.) Merrill (Fabales: Fabaceae) (Bueno et al, 2021). The soybean aphid (SBA), Aphis glycines Matsumura (Hemiptera: Aphididae), is a significant soybean pest, especially in the upper Midwest of the United States (Hesler and Beckendorf, 2021). Aphids are phloem-sucking insects that cause local injury to leaf tissue and systemic disruption of plant physiology (Macedo et al, 2003).…”

“…Insecticide application remains an effective management strategy for preventing outbreaks of soybean aphids ( Mokbel, 2019 ; Aseperi et al, 2020 ; Valmorbida et al, 2022 ). The first generation of neonicotinoids imidacloprid had an excellent control effect on the soybean aphid, and rapidly dominated the insecticide market since its production ( Stamm et al, 2016 ; Hesler and Beckendorf, 2021 ; Zhang et al, 2022 ). Although imidacloprid is effective against piercing–sucking pests, its frequent application still has negative effects.…”

Aphis glycines Matsumura (Hemiptera: Aphididae) is a major soybean pest that often poses a serious threat to soybean production. Imidacloprid is one of the commonly used insecticides to control the soybean aphid. To investigate the effect of termination of imidacloprid stress on the adaptive strategies of soybean aphid populations, we studied the growth, development, and related metabolism changes when the stress was terminated after 24 generations of imidacloprid stress on A. glycines. The results show that the A. glycines population accelerated its recovery and expanded its population size across generations. The longevity of the adults of the recovering population in the F12, F18, and F24 generations, respectively, was 1.11, 1.15, and 1.11 times longer than the control, while the fecundity was 10.38%, 11.74%, and 11.61% higher than that of the control. The net reproductive rate (R0) of the recovering population was always significantly higher than that of the control in the F1 to F24 generations. In addition, metabolisms related to the regulation of cell proliferation and oocyte meiosis were significantly upregulated in the recovering population. Even when the imidacloprid pressure disappeared, intergenerational stimuli still affected the adaptive strategies of soybean aphid populations. This effect was manifested as inhibiting the growth and development of the soybean aphid in the early generations and improving the fecundity of the soybean aphid in the later generations. Adaptive soybean aphid populations would surge in the absence of imidacloprid pressure. This study provides an important reference for exploring the adaptability of the A. glycines population under termination of stress from low lethal concentrations of imidacloprid across generations. It also provides important data for monitoring the population dynamics of A. glycines in the field and analyzing the degree of pharmacodynamic stress.
