Field studies were conducted to compare the performance of Goliath® Cockroach Gel (fipronil) and a spray treatment of Cislin Residual Insecticide (deltamethrin). These were carried out in Sydney, NSW, Australia against Blattella germanica (L), and Townsville, Queensland, against a mixed population of Periplaneta americana (L.) and Periplaneta australasiae (L). In both studies fipronil (0.05% AI...

Fipronil is a commonly used insecticide that has been shown to have environmental and human health risks. The current standard methods of detection for fipronil and its metabolites, such as GC-MS, are time consuming and labor intensive. In this study, a variant of systematic evolution of ligands by exponential enrichment (SELEX), was utilized to identify the first single-stranded DNA (ssDNA) mo...

this study was conducted to investigate commercial formulations of insecticides against western flower thrips, frankliniella occidentalis (pergande).the insects were collected from commercial greenhouses of cucumber in varamin, iran. the tested insecticides were diazinon (ec 60%), cypermethrin (ec 40%), fipronil (ec 2.5%), imidacloprid (sc 35%) and a botanical insecticide oxymatrine (kingbo, as...

tunneling and activity bioassays of chlorfenapyr, fipronil, and imidacloprid treated sand were conducted in the laboratory using Reticulitermes flavipes (Kollar). termites tunneled significantly less through sand treated with 1.0 ppm concentrations of fipronil and imidacloprid compared to the control and chlorfenapyr. Mortality after 7 d was 57, 25, and 29% for fipronil, chlorfenapyr, and imida...

The acute toxicity of fipronil and its sublethal effects on detoxification enzymes (carboxylesterases (CarEs), glutathione S-transferases (GSTs), and 7-ethoxycoumarin O-deethylase (ECOD)) in zebrafish (Danio rerio) were investigated. The results indicated that the 24-h LC50 of fipronil for zebrafish was 220.4 μg/L (95% CI: 173.7-272.4 μg/L). Sublethal concentrations of fipronil did not cause si...

An evaluation of several insecticides, namely, 0.01% fipronil, 0.05% indoxacarb, and 2% boric acid in liquid bait formulations were carried out against field populations of the longlegged ant, Anoplolepis gracilipes (Fr. Smith) (Hymenoptera: Formicidae). The baits were formulated in brown cane sugar solution (50%, wt:wt) and placed in an experimental bait station. Each bait was evaluated agains...

63 Three soils (a silt loam, loamy sand, sandy loam) found in Mississippi and pure silica sand were treated with fipronil and bioassayed using eastern subterranean termites, Reticulitermes jlavipes. Soils were treated with aqueous solutions ofTermidor (fipronil) at concentrations of 0, 0.12, 0.25,2.5, 5.0 and 20.0 ppm (wt AI: wt soil) that brought the soils to 15% moisture. Estimated lethal con...

A method for the determination of trace amounts of the insecticide fipronil was developed using solid-phase microextraction-gas chromatography-mass spectrometry and selected ion monitoring. Fipronil was extracted with a fused-silica fiber coated with 85 microm polyacrylate. The effects of pH, ionic strength, sample volume, extraction and desorption times as well as the extraction temperature we...

BACKGROUND Termiticides are applied at concentrations much higher than those used in agricultural settings. The longevity of fipronil has not yet been examined at the rates used for termite control, nor has the compound's movement in the soil been addressed. RESULTS Fipronil was detected in the eluates of treated soil cones, increasing initially and then decreasing to a steady concentration o...

Concerns over the role of pesticides affecting vertebrate wildlife populations have recently focussed on systemic products which exert broad-spectrum toxicity. Given that the neonicotinoids have become the fastest-growing class of insecticides globally, we review here 150 studies of their direct (toxic) and indirect (e.g. food chain) effects on vertebrate wildlife--mammals, birds, fish, amphibi...
