Fipronil, a broad-spectrum insecticide, is widely used in agriculture and veterinary practices. Fipronil-induced neurotoxicity potential adverse effects on humans aquatic organisms have raised health concerns. Monitoring programs been implemented globally to assess fipronil residues food, including fruits, vegetables, animal products. However, previous exposure assessments often focused specifi...

The efficacy of a novel topical combination of fipronil 9.8% (w/v) and (S)-methoprene 8.8% (w/v) (Fiprofort® Plus) was tested against ticks and fleas in naturally infested dogs. A total of fifty dogs were allocated in the study with ticks infestation (n = 35) and fleas infestation (n = 15). On day 0, thirty-five tick and fifteen flea infested dogs received the test formulation, a combination of...

Toxic effect concentrations of insecticides are generally determined using the technical grade or pure active ingredient. Commercial insecticide formulations, however, contain a significant proportion (>90%) of so-called inert ingredients, which may alter the toxicity of the active ingredient(s). This study compares the sublethal toxicity of two insecticides, the pyrethroid bifenthrin, and the ...

BACKGROUND Non-repellent insecticides, including fipronil and indoxacarb, are becoming increasingly important for soil treatments to manage the eastern subterranean termite, Reticulitermes flavipes (Kollar). The effects of these insecticides on termite walking and tunneling behavior could significantly reduce their efficacy against colonies. RESULTS Groups of R. flavipes were exposed to sever...

The title compound, C12H4Cl2F6N4OS {systematic name: 5-amino-1-[2,6-di-chloro-4-(tri-fluoro-meth-yl)phen-yl]-4-[(tri-fluoro-methane)sulfinyl]-1H-pyrazole-3-carbo-nitrile}, is a member of the phenyl-pyrazole group of acaricides, and one of the phenyl-pyrazole group of insecticides. The dihedral angle between the planes of the pyrazole and benzene rings is 89.03 (9)°. The fluorine atoms of the tr...

In the study reported here, the pioneer fipronil/(S)-methoprene topical product (Frontline® Plus, Merial Limited, Duluth, GA) was compared to the oral spinosad product (Comfortis® Elanco, Greenfield, IN) for efficacy against adult fleas and preventing egg production. The product presentations, doses and labelling were the one applicable in the USA. Using a standard protocol, 200 cat fleas of mi...

A 3-yr community-based study was conducted on residential properties on Mason's Island, Mystic, CT, to determine the efficacy of a rodent-targeted acaricide (fipronil) to control immature Ixodes scapularis (Say) on Peromyscus leucopus. Results indicated that modified commercial bait boxes were effective as an acaricide delivery method for reducing nymphal and larval tick infestations on white-f...

the compatibility of beauveria bassiana isolate debi 002 (atashgah) with fipronil, pyriproxyfenand hexaflumuron insecticides was assayed. to determine the impact of the insecticides on thegermination of the fungal spore, different concentrations of the compounds were added to the culturemedium (malt agar). in order to calculate the mycelial growth in different treatments, each colonydiameter wa...
