Environmental fate and properties of pyriproxyfen

Journal of Pesticide Sciences, 2008
Pyriproxyfen is a broad-spectrum insect growth regulator (IGR) with insecticidal activity against public health insect pests such as houseflies, mosquitoes and cockroaches. In agriculture and horticulture, pyriproxyfen has registered uses for the control of scale, whitefly, aphids and fire ants.

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.

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 (

Enantioselective dissipation of pyriproxyfen in soils and sand

Chirality, 2017
AbstractUnder normal conditions, the environmental behaviors of pesticides are affected by complex environmental factors and the manner of administration together with constraints. In order to meet the actual needs, we imitated the experiment and found that the degradation rate of pyriproxyfen in soils rendered complex changes.

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

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.
