“…These data corroborate conclusions from Miner (1966) that E. servus was generally of negligible concern as a pest of soybean and that N. viridula and A. hilare caused most of the damage from pentatomids in southeast Arkansas. McPherson et al (1979) found that the fecundity of N. viridula was Ϸ2.6-fold that of E. servus. E. servus also had a preoviposition period ϳ2 wk longer than that of N. viridula (McPherson et al 1979).…”

E. servus also had a preoviposition period ϳ2 wk longer than that of N. viridula (McPherson et al 1979). These two characteristics likely account for densities of E. servus not building to the damaging levels observed with N. viridula and A. hilare.…”

“…Stink bug biology and abundance on soybean has been studied in Arkansas and other southern states (Miner 1966;McPherson et al 1979McPherson et al , 1993Schumann and Todd 1982;McPherson 1996;Bundy and McPherson 2000), but changing insect control technologies and crop production systems have potentially altered ecological relationships between these insects and their host crops. Crop production practices widely deployed across the agricultural landscape such as boll weevil eradication and widescale planting of early season, indeterminant soybean may have impacted regulatory forces important in population growth of various key pest species.…”

From 2003 through 2007, densities of stink bugs were monitored weekly in 297 commercial production fields of early and late soybean, Glycine max L. Merrill, in southeast and southwest Arkansas. The goal of this research was to better understand seasonal abundance, species composition, and population dynamics of pentatomids as a benchmark reference for future management systems. Thirty-five percent of all the 25-sweep samples taken in soybean contained at least one stink bug specimen. The average density (mean +/- SEM) of stink bugs across all soybean samples was 1.84 +/- 0.06 per 25 sweeps. Overall, Nezara viridula L. was the most abundant species, although Euschistus serous (Say) was frequently found in soybean samples (18% of all samples). Peak densities of stink bugs in soybean were observed during the full-pod (R7) developmental stage. Approximately 25% of all soybean fields sampled had threshold densities (nine or more per 25 sweeps) at some time during the year, although 82 and 78% of fields in 2006 and 2007, respectively, reached threshold. At low densities (one to three stink bugs per 25 sweeps), E. serous comprised 50% of total stink bugs, but at high densities (> 71 stink bugs per 25 sweeps), N. viridula comprised 81% of total stink bugs. Piezodorus guildinii (Westwood) was observed as a pest of Arkansas soybean in 2005, and reproduction in soybean was documented in 2006 and 2007. Stink bugs seem to be a serious and increasingly important pest of soybean in southern Arkansas. Crop phenological development is a key factor in predicting colonization and population growth of stink bugs on Arkansas soybean, regardless of geographic region or type of soybean production system.

“…Other workers also reported greater damage as well as yield reduction after stink bug infestations during R3ÐR4 but not during R6 ÐR8 (Yeargan 1977) or R5ÐR7 (Thomas et al 1974). McPherson et al (1979) however observed that quality and yield were not affected by stink bug feeding during R5ÐR6. We found yield reduction after stink bug infestation during R3ÐR4 and R5.5 but saw no effect of infestation on weight per 100 seeds.…”

“…If soybeans are grown for seed, then a lower population (1.1 stink bugs per 2 m of row) justiÞes control. McPherson et al (1979) found signiÞcant yield reduction when soybean plants were exposed to southern green stink populations as low as 0.5 stink bugs per 0.3 m of row for 6 Ð7 wk, which demonstrates the adverse effect of subeconomic infestation levels over prolonged periods. This study, along with the earlier reports of Todd and Turnipseed (1974) and Yeargan (1977) that designated one stink bug per 0.3 m of row as intolerable, likely were instrumental in the establishment of many economic thresholds for stink bugs in the southern United States.…”

Delayed Maturity Associated with Southern Green Stink Bug (Heteroptera: Pentatomidae) Injury at Various Soybean Phenological Stages

Delayed maturity in soybean, Glycine max (L.) Merr., occurred in response to infestation by southern green stink bug, Nezara viridula (L.), in 4 yr of field studies. Maturity delays followed stink bug infestation that occurred only during the pod set and filling stages (R3-R5.5), and infestations at R3-4 and R5 resulted in delayed maturity more consistently than did infestation at R5.5. Infestation levels of six stink bugs per 0.3 m of row for 7-14 d generally were required to delay soybean maturity. The greatest impact on seed yield and quality parameters followed stink bug infestations that occurred during R3-R5.5, which corresponded closely with the periods of infestation that resulted in delayed maturity. If both delayed maturity and yield reduction are considered, the pod elongation through late pod filling stages were most critical for protecting soybeans from southern green stink bugs.

Nanoparticles are being utilized in agriculture as fertilizers, pesticides, and agrochemical‐carriers. Designed to be biocompatible and degradable, biopolymer nanoparticles were developed as an alternative to metallic nanoparticles, and though safe‐by‐design, polymeric nanoparticles must be field‐tested prior to largescale use. Several field studies were conducted to observe detrimental effects of biopolymer nanoparticles on plant growth and yield using soybean, Glycine max (L.) Merr., as a model system. Biopolymer nanoparticles made from lignin or zein were applied as seed treatments to soybean seeds or as foliar sprays (zein only) to soybean plants. Studies using biopolymer nanoparticle seed treatments (nano‐STs) measured the germination rates and seedling growth were evaluated in the laboratory, while stand counts, plant height, growth stage, yield, and hundred‐seed weight were measured in the field. Foliar treatments assessed nanoparticle impact on flower abortion and pod production. To ensure nano‐STs would not compromise the plant's defensive capabilities, herbivore feeding was assessed using a leaf bioassay for defoliators and a seed damage index for pod feeders. Growth rate, percent germination, or root length were not impacted by nano‐STs. In the field, nano‐STs had no impact on stand counts, heights, growth stage, yield, and hundred‐seed weights. Leaf feeding assays and damage indices indicate plant susceptibility to herbivore attack was not increased due to nano‐STs. Foliar applications of zein nanoparticles did not increase flower abortion or decrease pod set. These results indicate that biopolymer nanoparticles have no negative effects on growth, yield, and herbivore susceptibility and should be suitable for use in agriculture.
