House flies, Musca domestica L. (Diptera: Muscidae) are mechanical vectors of many diseases on poultry facilities and have the ability to develop resistance to different insecticides. The aim of the present study was to assess the resistance status of house flies to neonicotinoids and insect growth regulators (IGR) from poultry facility populations in Punjab, Pakistan. M. domestica populations ...

Insect nicotinic acetylcholine receptors (nAChRs) are among the most prominent and most economically important insecticide targets. Thus, an understanding of the modes of binding of respective agonists is important for the design of specific compounds with favorable vertebrate profiles. In the case of nAChRs, the lack of available high-resolution X-ray structures leaves theoretical consideratio...

The nicotinic acetylcholine (ACh) receptor (nAChR) is the principal insecticide target. Nearly half of the insecticides by number and world market value are neonicotinoids acting as nAChR agonists or organophosphorus (OP) and methylcarbamate (MC) acetylcholinesterase (AChE) inhibitors. There was no previous evidence for in vivo interactions of the nAChR agonists and AChE inhibitors. The nitrome...

BACKGROUND The Asian citrus psyllid, Diaphorina citri (Hemiptera: Psyllidae), is the most destructive pest of citrus in Florida. The development of insecticide resistance in several populations of D. citri has been documented. There is an urgent need to develop and integrate novel tools for the successful management of D. citri and also to prevent the development of insecticide resistance. RE...

A key new risk to our pollinators has been identified as exposure to neonicotinoid insecticides. These discoveries have refuelled the debate over whether or not the neonicotinoid insecticides should be banned and conflicting evidence is used in this battle. However, the issue is not black or white, but gray. It is not an issue of whether the neonicotinoids are toxic to insects or not. Clearly, ...

Japanese beetle,Popillia japonicaNewman(Coleoptera: Scarabaeidae), is an important quarantine pest of nurseries. Nursery plant movement from P. japonica-infested regions is regulated by the U.S. Domestic Japanese Beetle Harmonization Plan (DJHP), which classiÞes states by risk categories. Treatments for category 2 states include preharvest soil surface treatment of nursery plants grown in Þeld ...

The widespread usage of neonicotinoid insecticides has sparked concern over their effects on non-target organisms. While research has largely focused on terrestrial systems, the low soil binding and high water solubility of neonicotinoids, paired with their extensive use on the landscape, puts aquatic environments at high risk for contamination via runoff events. We assessed the potential threa...

Since their discovery in the late 1980s, neonicotinoid pesticides have become the most widely used class of insecticides worldwide, with large-scale applications ranging from plant protection (crops, vegetables, fruits), veterinary products, and biocides to invertebrate pest control in fish farming. In this review, we address the phenyl-pyrazole fipronil together with neonicotinoids because of ...
