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 ...

Formulation of pyriproxyfen, a juvenile hormone mimic, for tsetse control

Medical and Veterinary Entomology, 1990
ABSTRACT. A topical dose, in 1 uJ acetone, of 0.02 |xg 2‐[l‐methyl‐2‐(4‐phenoxyphenoxy) ethoxy] pyridine, the juvenile hormone mimic pyriproxyfen (S‐31183, Sumitomo Chemical Co.), caused an adult female tsetse, Glossina morsitans morsitans Westwood, to produce non‐viable ...

Gene expression in pyriproxyfen‐ resistant Bemisia tabaci Q biotype

Pest Management Science, 2007
Abstract Pyriproxyfen is a biorational insecticide that acts as a juvenile hormone (JH) analogue and disrupts insect development with an unknown molecular mode of action. Pyriproxyfen is one of the major insecticides used to control the whitefly Bemisia tabaci (Gennadius ...

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 ...

Environmental risk assessment (ERA) of pyriproxyfen in non-target aquatic organisms

Aquatic Toxicology, 2020
Pyriproxyfen (PPF) is a synthetic substance and an insect juvenile hormone agonist with growth regulating effect. It is used worldwide as a pesticide in agriculture and public health campaigns, including the control of Aedes aegypti proliferation. It has low volatility, high Kow value and high lability in aerobic aquatic systems but is considered ...

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

Field Evaluation of Resistance to Pyriproxyfen in Bemisia tabaci (B Biotype)

Journal of Economic Entomology, 2007
We determined effects of aerial sprays of the insect growth regulator pyriproxyfen on sweetpotato whitefly, Bemisia tabaci (Gennadius) (B biotype), in Arizona cotton (Gossypium spp.) fields. We measured survival for males and females from a susceptible strain and a laboratory-selected resistant strain, as well as for hybrid female progeny from crosses ...

Pharaoh Ant (Hymenoptera: Formicidae) Colony Development After Consumption of Pyriproxyfen Baits

Journal of Economic Entomology, 1995
Pharaoh ant, Monomorium pharaonis (L.), colonies were effectively controlled following ingestion of pyriproxyfen formulated in peanut butter oil. Pyriproxyfen, a juvenile hormone analog, reduced egg production in the queens, decreased the amount of brood due to delayed death in the eggs and larvae, caused death of pupae about 3 wk after treatment, and ...

The enantioselective environmental behavior and toxicological effects of pyriproxyfen in soil

Journal of Hazardous Materials, 2019
We synthesized nine pyriproxyfen (PYR) metabolites and developed a chiral residual analysis method for PYR with its metabolites in five soils using ultra performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS). Soil degradation research showed that higher organic matter content and bigger soil particle size were conducive to the ...
