Effects of pyriproxyfen on zebrafish brain mitochondria and acetylcholinesterase

Chemosphere, 2021
Pyriproxyfen is an insecticide used worldwide that acts as a biomimetic of juvenile hormone. This study investigated metabolic and synaptic impairments triggered by pyriproxyfen using zebrafish acetylcholinesterase (zbAChE) and mitochondria as markers.

Fate and ecotoxicological effects of pyriproxyfen in aquatic ecosystems

Environmental Science and Pollution Research, 2020
Pyriproxyfen is an insect growth regulator acting as larvicide against a large spectrum of public health insect pests, especially dipterans. It is also widely used in agriculture and horticulture for the control of many insect species. Disrupting the endocrine system by mimicking the activity of the juvenile hormone, pyriproxyfen interferes with ...

Pyriproxyfen cyclodextrin inclusion compounds

Journal of Inclusion Phenomena and Macrocyclic Chemistry, 2015
Pyriproxyfen is a pyridine based pesticide which is effective against mosquito larvae. Here we report the inclusion complexes (ICs) between guest pyriproxyfen and host β and γ cyclodextrins, but not with α cyclodextrin, based on WAXD, DSC, FTIR, and TGA characterization results. We show that one pyriproxyfen molecule is covered with between one and two

Determination by chromatography and cytotoxotoxic and oxidative effects of pyriproxyfen and pyridalyl

Chemosphere, 2019
Pyriproxyfen (PPF) is a larvicide, used to combat the proliferation of Aedes aegypti larvae. The objective of this study was to analyze the compounds of pyriproxyfen and pyridalyl (PYL) in a commercial larvicide to analyze the cytotoxic and oxidative effects of PPF and PYL. The toxic potential of PPF and PYL were assessed based on lethal concentration (

Metabolism of Pyriproxyfen in Rats. 1. Absorption, Disposition, Excretion, and Biotransformation Studies with [phenoxyphenyl-14C]Pyriproxyfen

Journal of Agricultural and Food Chemistry, 1995
Male and female rats were given a single oral dose of [phenoxyphenyl- 14 C]pyriproxyfen [4-phenoxyphenyl (R,S)-2-(2-pyridyloxy)propyl ether] at 2 (low dose) or 1000 (high dose) mg/kg. 14 C was rapidly excreted into feces and urine, with the former route predominating (about 90% of the dose). Peak 14 C concentrations in blood, kidney, liver, and other

Dissipation of fenoxycarb and pyriproxyfen in fresh and canned peach

Journal of Environmental Science and Health, Part B, 2007
The objective of this work was to determine the dissipation of fenoxycarb and pyriproxyfen in fresh and canned peaches in order to know the levels of residues that can reach consumers in real circumstances. Two field dissipation studies were carried out, one of them at the pre-harvest interval (PHI) with good agricultural practice (GAP) and the other ...

Tomato Metabolism and Porphyrin-Catalyzed Oxidation of Pyriproxyfen

Journal of Agricultural and Food Chemistry, 2005
Investigation of the metabolism of [(14)C]pyriproxyfen [4-phenoxyphenyl (R,S)-2-(2-pyridyloxy)propyl ether] in tomato fruits (Lycopersicon esculentum Mill. cv. Ponterosa) was conducted by topical application of acetonitrile solution or emulsifiable concentration formulation three times at 35, 21, and 7 days before harvest.

Controlled-Release Systems for the Insect Growth Regulator Pyriproxyfen

Journal of Agricultural and Food Chemistry, 2003
A simple technique was developed for the production of controlled-release systems (CRSs) for pyriproxyfen, an insect growth regulator active against the larvae of Culex pipiens, the most common species of mosquito found in developed countries. The CRSs consisted of a spongy core material encapsulated in a coating of a polyurethane or polyurea hydrogel,

Pyriproxyfen toxicity to fish and crustaceans: A literature review

Environmental Research
Pyriproxyfen (PPF) is an insect growth regulator (IGR) that acts as a juvenile hormone agonist (JHA). It is widely used as a larvicide to control insect vectors, as antiparasitic medicines, and for pest control in domestic and agricultural environments. Reports in the literature show that PPF is toxic to fish and non-target crustaceans. Therefore, this

Biochemical and teratogenic effects of a mixture of pyriproxyfen and glyphosate

Comparative Biochemistry and Physiology Part C: Toxicology & Pharmacology
The mixture of agrochemicals can be made to improve pest control or accidentally. In this way, the effects on non-target organisms are a critical aspect of the environment and heath. Thus, this work aimed to show how a mixture of pyriproxyfen, and glyphosate can impair biochemical routes and embryonic development.
