“…Imidacloprid, dinotefuran, and thiamethoxam were more toxic to the filth fly parasitoid Spalangia endius (Hymenoptera: Pteromalidae) than to the target pest (Musca domestica), thus making it unsuitable for controlling the flies (Burgess and King 2015). Also S. endius was attracted to imidacloprid granular baits and experienced more grooming activity, but not to those containing dinotefuran or other insecticides.…”

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 .

“…For example, thiamethoxam did not affect parasitoids, while imidacloprid reduced braconid, aphelinid and scelionid wasps. Burgess and King (2015) previously found that the LC 50 of imidacloprid was 4.5 times lower than that of thiamethoxam for a parasitoid of houseflies. Imidacloprid has a longer half-life and is an older chemical than thiamethoxam (Bonmatin et al, 2015; Simon-Delso et al, 2015), which could explain its greater non-target impacts.…”

311. While many studies have investigated non-target impacts of neonicotinoid seed treatments 32 (NSTs), they usually take place within a single crop and focus on specific pest or beneficial 33 arthropod taxa. 34 2. We compared the impacts of three seed treatments to an untreated control: imidacloprid + 35 fungicide products, thiamethoxam + fungicide products, and fungicide products alone in a three- 36 year crop rotation of full-season soybean, winter wheat, double-cropped soybean and maize. 37Specifically, we quantified neonicotinoid residues in the soil and in weedy winter annual flower 38 buds and examined treatment impacts on soil and foliar arthropod communities, and on plant 39 growth and yield. 40 3. Trace amounts of insecticide were found in winter annual flowers of one species in one site 41year, which did not correspond with our treatments. Although low levels of insecticide residues 42 were present in the soil, residues were not persistent. Residues were highest in the final year of 43 the study, suggesting some accumulation. 44 4. We observed variable impacts of NSTs on the arthropod community; principle response curve 45 analysis, diversity and evenness values exhibited occasional community disturbances, and 46 treatments impacted the abundance of various taxa. Overall, imidacloprid had a greater effect 47 than thiamethoxam, with the fungicide only treatment also occasionally impacting communities 48 and individual taxa.49 5. Pest pressure was low throughout the study, and although pest numbers were reduced by the 50 insecticides no corresponding increases in yield were observed. However, the fungicide products 51 contributed to higher yields in wheat.52 6. Synthesis and applications. Pesticide seed treatments can disturb arthropod communities, even 53 when environmental persistence and active ingredient concentrations are low. The foliar 54 3community in wheat and maize exhibited a trend of increasing disturbance throughout the 55 sampling period, suggesting that recovery from the impacts of NSTs is not always rapid. Our 56 study is among the first to demonstrate that seed applied fungicides alone can disrupt arthropod 57 communities in agroecosystems and highlights the need for further investigation into the impacts 58 of seed applied fungicides. 59 Key words 60 Fungicides; Imidacloprid; Glycine max L.

“…Such exposure kills ~10% of females and no males. Parasitoids might encounter this concentration on a farm because 0.91535 μg/cm 2 of imidacloprid is the recommended application rate for imidacloprid when it is in house fly bait (Burgess and King 2015), and the pesticide disseminates and degrades over time (Rouchaud et al 1996, Burgess et al 2018.…”

“…In a Florida strain of S. endius, survival and subsequent ability to produce progeny and reduce fly numbers was reduced by contact with imidacloprid on a glass surface at concentrations well above recommended application rates (Burgess and King 2015). However, if females then had to move through manure-like media to locate hosts, parasitization ability was no longer affected (Burgess et al 2017).…”

Decaying Organic Matter Does Not Remove Sublethal Effects of Imidacloprid on Mating in Spalangia endius (Hymenoptera: Pteromalidae), a Parasitoid of Filth Flies

Both the parasitoid wasp Spalangia endius Walker and the insecticide imidacloprid are used to control house flies. A recent study found that negative sublethal effects of imidacloprid on killing flies and on offspring production by this parasitoid wasp are eliminated when females have the opportunity to crawl through decaying matter. An enzyme-linked immunosorbent assay showed that the presence of decaying matter reduces the amount of pesticide on their bodies. This study examined whether this was also true for sublethal effects on mating. S. endius were exposed to a realistic concentration of imidacloprid that induces very low mortality. Then, individual parasitoids were allowed to burrow through decaying organic matter or not, followed by mating tests in the absence of decaying matter. Even after 24 h with the decaying matter, copulation for both males and females that had previously been exposed to imidacloprid was delayed compared with no-pesticide controls. Furthermore, for pesticide-exposed males, subsequently burrowing through media made copulation even more delayed than if they were not exposed to media. For pesticide-exposed females, subsequently burrowing through media neither increased or decreased the negative effect of the pesticide exposure. Together with other studies, these results reinforce that use of S. endius and use of imidacloprid are incompatible, even at much lower than recommended concentration, unless application is sufficiently separated in place and time.
