“…Certain sucking predators ingest systemic insecticides by feeding on the plant, such as O. insidiosus, which is known to probe plants and remove plant juices during periods of drought or limited prey . Eggs can be directly exposed within the oviposition site, and O. insidious eggs placed in sunflowers Helianthus annuus L. grown from thiamethoxam‐treated seeds exhibited reduced adult survival and fecundity . Adult parasitoids can be directly exposed to the systemic insecticide by feeding on extrafloral nectar or guttation liquid, the latter of which is a common phenomenon during the seedling stages of corn.…”

“…6 However, their presence on the seed coating as well as the systemic activity in the plant can pose non-target risks. 7 Negative effects from direct and indirect exposure to neonicotinoids have been reported for a number of beneficial insects including: Coleoptera: Coccinellidae, Carabidae, Staphylinidae [8][9][10][11][12] ; Hemiptera: Anthocoridae, Lygaeidae, Pentatomidae, Reduviidae [13][14][15] ; Neuroptera: Chrysopidae 14,16 and hymenopteran parasitoids. 13,[17][18][19][20] Furthermore, a meta-analysis of 20 field studies 21 reported an overall approximately 16% reduction in natural enemy abundance, which was comparable to the impact caused by foliar and soil-applied pyrethroids.…”

Clothianidin primarily influenced arthropod communities during the 4 weeks following planting, with disruptions to major natural enemy taxa, but communities showed trends toward recovery at the later corn stages. While the insecticide suppressed multiple herbivores, none were economically damaging to corn; thus, the pest suppression benefits of clothianidin observed in this study did not justify the non-target impacts. © 2018 Society of Chemical Industry.

“…Although numerous studies have recently investigated neonicotinoid effects on performance measures (e.g., reproduction, behavior) of various beneficial insect species, no quantitative synthesis of this growing body of literature currently exists. Furthermore, results from neonicotinoid lab and field studies present highly variable and conflicting results when assessing similar insect response metrics or even the same insect species (e.g., Orius insidiosus reproduction; Gontijo et al 2015, Fernandes et al 2016.

Neonicotinoid insecticides are currently the fastest-growing and most widely used insecticide class worldwide. Valued for their versatility in application, these insecticides may cause deleterious effects in a range of non-target (beneficial) arthropods. However, it remains unclear whether strong patterns exist in terms of their major effects, if broad measures of arthropod performance are negatively affected, or whether different functional groups are equally vulnerable. Here, we present a meta-analysis of 372 observations from 44 field and laboratory studies that describe neonicotinoid effects on 14 arthropod orders across five broad performance measures: abundance, behavior, condition, reproductive success, and survival. Across studies, neonicotinoids negatively affected all performance metrics evaluated; however, magnitude of the effects varied. Arthropod behavior and survival were the most negatively affected and abundance was the least negatively affected. Effects on arthropod functional groups were inconsistent. Pollinator condition, reproductive success, and survival were significantly lower in neonicotinoid treatments compared to untreated controls; whereas, neonicotinoid effects on detritivores were not significant. Although magnitude of arthropod response to neonicotinoids varied among performance measures and functional groups, we documented a consistent negative relationship between exposure to neonicotinoid insecticides in published studies and beneficial arthropod performance.

“…Lower densities of this important food source (thrips) could, in theory, result in lower densities of O. insidiosus; however, this trend was not observed in our experiments. Direct impacts on O. insidiosus from thiamethoxam seed-treatments have been documented in previous laboratory studies, in which lethal and sublethal effects to O. insidiosus via direct exposure to thiamethoxam-treated plants were observed (Prabhaker et al 2011, Seagraves and Lundgren 2012, Gontijo et al 2015. Despite the potential for thiamethoxam treatments to have negative impacts on O. insidiosus via depletion of their food source (thrips), acute toxicity or sublethal effects, our experiments did not detect any impacts of thiamethoxam-grown snap beans on densities of O. insidiosus (Table 3).…”

Thiamethoxam is a neonicotinoid insecticide commonly applied directly to the seeds (seed-treatment) of commercial snap beans, Phaseolus vulgaris L. While previous studies have examined target and nontarget effects of thiamethoxam seed-treatments in snap beans and other crops, to our knowledge, none have been conducted in agroecosystems predominated by the pest Mexican bean beetle, Epilachna varivestis Mulsant (Coleoptera: Coccinellidae). This study examined the effects of thiamethoxam-treated snap beans on E. varivestis, other arthropods, and crop performance in southwestern Virginia. Greenhouse experiments were conducted to evaluate residual toxicity of treated snap beans to E. varivestis and a key predator, Podisus maculiventris (Say) (Hemiptera: Pentatomidae). Treated plants were highly toxic to E. varivestis at 13 d, moderately toxic from 16 to 20 d, and minimally toxic at 24 d. P. maculiventris was unaffected by exposure to treated plants or by feeding on E. varivestis that consumed treated plants. Small plot field experiments in 2014 and 2015 showed no significant effects of thiamethoxam seed-treatments on E. varivestis densities, other arthropods, crop injury, or yield. In 2016, planting was delayed by persistent rain, resulting in early E. varivestis colonization. In this year, thiamethoxam-treated plants had significantly lower densities and feeding injury from E. varivestis, followed by significantly higher yields. Natural enemies were unaffected by seed-treatments in all field experiments. These experiments demonstrated that thiamethoxam seed-treatments provide control of E. varivestis when beetles infest fields within 2 to 3 wk after planting; but otherwise provide negligible advantages. Negative effects from thiamethoxam seed-treatments on nontarget arthropods appear minimal for snap beans in this region.
