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 ...

Incorporation of Pyriproxyfen in a German Cockroach (Dictyoptera: Blattellidae) Management Program

Journal of Economic Entomology, 1991
Pyriproxyfen (Nylar), a juvenile hormone analog (JHA), and acephate were used in a German cockroach, Blattella germanica (L.), management program. Monthly applications of acephate for 6 mo reduced nightly trap catches from 24.68-25.25 to 4.46-5.31 at 2 mo, and trap catches averaged 1.49-8.04 from 2-6 mo.

Effects of Pyriproxyfen Treatment on the Insect Growth Rates

Entomological Research, 2011
Larvae of Bombyx mori fed on the mulberry leaves treated with pyriproxyfen extended the larval duration. The silkworm on the third day of the fourth instar fed pyriproxyfen 10‐6 concentration extended the fifth instar duration over 20 days and was not able to spinning silk.

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.
