“…Taken together, feeding B. impatiens brood acetamiprid-contaminated pollen at 4520 µg/kg resulted in larval mortality and provides an explanation for the observed reductions in drone production. This observation has precedence within the literature because acetamiprid can cause larval mortality in a variety of other invertebrates (Zabel et al 2001;Mo et al 2002;Kuhar et al 2006;Amirzade et al 2014).…”

Honey bees and other wild bee species including bumble bees have experienced population declines in recent decades. Although many stressors are implicated in bee population declines, much attention has focused on neonicotinoid pesticides, which are widely used and known to be toxic to pollinators. One neonicotinoid, acetamiprid, has been studied very little in bumble bees, despite its use on bumble bee-pollinated crops. We assessed the impacts of acetamiprid to the North American bumble bee Bombus impatiens using the microcolony model. We examined nest growth, development, and subsequent nest productivity as measured by drone production. We found that high concentrations of acetamiprid in pollen (4520 µg/kg) significantly impacted nest growth, development, and, ultimately, reproduction (drone production). We found the no-observable-adverse effect level to be 45.2 µg/kg. Overall, acetamiprid has the potential to negatively impact reproductive endpoints for B. impatiens. However, effects occurred at concentrations substantially higher than expected environmental concentrations that would be achieved when following label rates. Further work is required to assess the effects of this pesticide on B. impatiens via alternate routes of exposure and on queenright colonies.

“…Compatibility studies of natural enemies with insecticides are important to know the range of tolerance that BCAs have to pesticides, especially in key BCAs such as Orius species. There are several studies on the toxicity of thiamethoxam and/or imidacloprid in various species of Orius (Tang et al, ; Dağlı & Bahşi, ; Phrabaker et al, ; Herrick & Cloyd, ) and other natural enemies (Armizade et al, ; Phrabaker et al, ; Herrick & Cloyd, ). However, these studies were based on testing a single population, which may be inaccurate as they are not considering the potential natural variability in tolerance to insecticides among populations (Roush et al, ).…”

Imidacloprid and thiamethoxam are neonicotinoids that have been tested in several Orius species, including Orius laevigatus (Fieber) (Hemiptera: Anthocoridae), but not the variability in their effect among Orius populations of a single species. In this study, the variation in susceptibility to imidacloprid and thiamethoxam in 30 Mediterranean wild populations and four commercial populations of O. laevigatus was investigated in the laboratory using a standard dip bioassay method. Lethal concentration values (LC 50 ) and the mortality of adults at the maximum field rate (MFR) were calculated. The range of LC 50 of thiamethoxam was from 0.7 to 5.9 mg l À1 , an 8.4-fold variability, obtaining mortality at MFR (100 mg l À1 ) of >89.1% in all populations. The baseline obtained a value of 2.1 mg l À1 , which is very low compared to the MFR. For imidacloprid, the LC 50 varied from 7.7 to 94.7 mg l À1 (12.3-fold variability). Mortalities at the MFR (150 mg l À1 ) were 57.7-99.2%, that is, more variable than for thiamethoxam. The LC 50 value of the baseline was 48.7 mg l À1 , also low compared to the MFR. This variation was exploited to select two populations resistant to thiamethoxam and imidacloprid, respectively. Artificial selection for on average 40 cycles significantly increased the resistance to thiamethoxam (LC 50 = 149.1 mg l À1 ) and imidacloprid (LC 50 = 309.9 mg l À1 ). Mortalities at the MFR in the thiamethoxam-and imidacloprid-resistant populations were 44.5 and 36.9%, respectively. These results demonstrate that resistance can be enhanced in biocontrol agents by artificial selection under laboratory conditions, starting with populations showing no or very low tolerance. Our neonicotinoid-resistant populations might enhance the wider adoption of biological control by allowing punctual or hotspot applications of neonicotinoids to control several main and secondary pests.

New information on the lethal and sublethal effects of neonicotinoids and fipronil on organisms is presented in this review, complementing the previous Worldwide Integrated Assessment (WIA) in 2015. The high toxicity of these systemic insecticides to invertebrates has been confirmed and expanded to include more species and compounds. Most of the recent research has focused on bees and the sublethal and ecological impacts these insecticides have on pollinators. Toxic effects on other invertebrate taxa also covered predatory and parasitoid natural enemies and aquatic arthropods. Little new information has been gathered on soil organisms. The impact on marine and coastal ecosystems is still largely uncharted. The chronic lethality of neonicotinoids to insects and crustaceans, and the strengthened evidence that these chemicals also impair the immune system and reproduction, highlights the dangers of this particular insecticidal class (neonicotinoids and fipronil), with the potential to greatly decrease populations of arthropods in both terrestrial and aquatic environments. Sublethal effects on fish, reptiles, frogs, birds, and mammals are also reported, showing a better understanding of the mechanisms of toxicity of these insecticides in vertebrates and their deleterious impacts on growth, reproduction, and neurobehaviour of most of the species tested. This review concludes with a summary of impacts on the ecosystem services and functioning, particularly on pollination, soil biota, and aquatic invertebrate communities, thus reinforcing the previous WIA conclusions .
