Toxicity and detoxification of imidacloprid in mouse ovarian follicles
… and within mammals into more toxic metabolites. Imidacloprid (IMI) was the first neonicotinoid synthesized and continues to be the most popular member of the neonicotinoid family today. Mammals are exposed to IMI primarily through ingestion of contaminated food and water as well as through …

Eastern Hemlock Needle Physiology as Impacted by Hemlock Wooly Adelgid and Treatment with Imidacloprid
… half of the trees at each site were treated with imidacloprid (Merit® 2 F, Bayer, Kansas City, MO) while the rest were left untreated. Needle gas exchange was assessed monthly using a LI-COR 6400 portable open path gas exchange system (LI-COR Inc, Lincoln NE). Chlorophyll fluorescence and bud …

Toxicological Analysis of the Neonicotinoid Insecticide Imidacloprid to Honey Bees, Apis mellifera, of Different Colonies
… sensitivities to the neonicotinoid insecticide imidacloprid, which suggest a mechanism of tolerance to the insecticide in certain colonies. In this study, I examined the imidacloprid sensitivity of honey bees collected from different colonies. After determining a range of LC50 values in the …

Amelioration of acute and chronic toxicity of imidacloprid by dietary phytochemicals in honey bees (apis mellifera)
… practices. In particular, the neonicotinoid imidacloprid has been targeted as a potentially strong contributor to colony decline. Imidacloprid is a systemic pesticide, and honey bees are challenged by its presence in nectar, pollen, water, and beeswax. In the presence of imidacloprid, honey …

Prey-mediated effects of imidacloprid on Laricobius nigrinus (Coleoptera: Derodontidae) and Sasajiscymnus tsugae (Coleoptera: Coccinellidae), two predators of hemlock woolly adelgid
Prey-mediated effects of imidacloprid were evaluated for Laricobius nigrinus Fender and Sasajiscymnus tsugae Sasaji and McClure after feeding on hemlock woolly adelgid (HWA), Adelges tsugae Annand (Hemiptera: Adelgidae). Two methods were evaluated for detecting imidacloprid in hemlock tissues: a …

Sub-lethal and lethal effects of a neonicotinoid pesticide on the development of Northern leopard frog tadpoles.
… to declining populations (Bruhl et al. 2013). Imidacloprid is the most widely used insecticide in the world, but few studies have considered its potential effects on anurans. I conducted a static-renewal experiment to monitor the lethal and sub-lethal, developmental effects in Northern leopard …

Studies on the Subterranean Activity of Laricobius spp. (Coleoptera: Derodontidae) using 3D X-ray Analysis and Three Imidacloprid Soil Application Techniques
… control agents within IPM scenarios for HWA. Imidacloprid (IMI), the most widely used insecticide for HWA management, is typically applied to the soil below HWA infested trees and breaks down into several metabolites, including two with insecticidal properties; 5-hydroxy imidacloprid (5H-IMI) …

Development of liquid chromatography-mass spectrometry protocols for quantification of imidacloprid in pig urine and for analysis of 5α-cyprinol sulfate metabolism in zebrafish
… we quantified the levels of a neonicotinoid, imidacloprid (IMI), in pig urine using a spike of internal standard D4-Imidacloprid (D4-IMI) at known concentration. The urine samples were prepared using a modified solid phase extraction (SPE). This experiment is an example of a targeted LC/MS …

Field and laboratory evaluation of the interactions between pesticides and the gut microbiome in Honey Bees (Apis mellifera)
… numerous pesticides while foraging (e.g. imidacloprid, a neonicotinoid insecticide) or in the hive colony (e.g. Tau-fluvalinate, a miticide commonly used to treat Varroa mite parasites). Similar to most organisms, the gut microbiome is important for bee health, metabolism, and behavior, …

Quantification of insecticide resistance in the tobacco-adapted form of the green peach aphid, Myzus persicae (Sulzer)(Hemiptera: Aphididae)
… information on the aphid's susceptibility to imidacloprid and other insecticides is critical for developing future resistant management programs to minimize losses attributed to the aphid. Studies were conducted on colonies of the tobacco-adapted form of the green peach aphid collected from …

Assessing the Effects of Chronic Neonicotinoid Insecticide Exposure on Aquatic Insects using Multiple Experimental Approaches
… laboratory conditions, I compared the effects of imidacloprid, clothianidin, thiamethoxam on the model aquatic insect, Chironomus dilutus. Reduced emergence success, advanced emergence timing, and male-biased sex ratios were observed across all compounds tested. Imidacloprid and clothianidin …

Interactions of insecticides, entomopathogenic fungi, and earthworms as they relate to white grub IPM in turfgrass systems
… Virginia. Insecticides such as the neonicotinoid imidacloprid are commonly applied to turfgrass in order to control these pests. As an alternative to synthetic insecticides, entomopathogenic fungi (EPF), including Metarhizium brunneum (Petch) and Beauveria bassiana (Balsamo) Vuillemin may also be …

Reaction of the marine flatworm Macrostomum lignano exposed to xenobiotics
… worms were more susceptible to fipronil than to imidacloprid. Various antioxidant enzymes of the host were downregulated in response to exposure to the xenobiotics, including Prdx1, Sod2, and Mdr5. Of the ROS-detoxifying enzymes, only Gstp1 showed significant upregulation. Xenobiotics also …
