In Silico Prediction of the Mechanism of Action of Pyriproxyfen and 4′-OH-Pyriproxyfen against A. mellifera and H. sapiens Receptors [PDF]

open access: yesInternational Journal of Molecular Sciences, 2021
Background. Poisoning from pesticides can be extremely hazardous for non-invasive species, such as bees, and humans causing nearly 300,000 deaths worldwide every year. Several pesticides are recognized as endocrine disruptors compounds that alter the production of the normal hormones mainly by acting through their interaction with nuclear receptors ...

The Automatic Classification of Pyriproxyfen-Affected Mosquito Ovaries [PDF]

open access: yesInsects, 2021
Pyriproxyfen (PPF) may become an alternative insecticide for areas where pyrethroid-resistant vectors are prevalent. The efficacy of PPF can be assessed through the dissection and assessment of vector ovaries. However, this reliance on expertise is subject to limitations.

Susceptibility of South Texas Aedes aegypti to Pyriproxyfen [PDF]

open access: yesInsects, 2021
An integral part to integrated mosquito management is to ensure chemical products used for area-wide control are effective against a susceptible population of mosquitoes. Prior to conducting an intervention trial using an insect growth regulator, pyriproxyfen, in South Texas to control Aedes aegypti, we conducted a larval bioassay to evaluate baseline ...

Crystal structure of pyriproxyfen [PDF]

open access: yesActa Crystallographica Section E Crystallographic Communications, 2015
In the title compound {systematic name: 4-phenoxyphenyl (RS)-2-[(pyridin-2-yl)oxy]propyl ether}, C20H19NO3, which is a juvenile hormone mimic and insecticide, the dihedral angles between the plane of the central benene ring and those of the pendant pyridine ring and phenyl ring are 78.09 (6) and 82.14 (8)°, respectively. The conformation of the O—C—C—O

Pyriproxyfen, a juvenile hormone analog, damages midgut cells and interferes with behaviors of Aedes aegypti larvae [PDF]

open access: yesPeerJ, 2019
Juvenile hormone analogs (JHA) are known to interfere with growth and biosynthesis of insects with potential for insecticide action. However, there has been comparatively few data on morphological effects of JHA on insect organs.

A Possible Link Between Pyriproxyfen and Microcephaly [PDF]

open access: yesPLoS Currents, 2016
The Zika virus has been the primary suspect in the large increase in incidence of microcephaly in 2015-6 in Brazil. However its role is not confirmed despite individual cases in which viral infections were found in neural tissue. Recently, the disparity between the incidences in different geographic locations has led to questions about the virus’s role.

Evolving resistance patterns in Tetranychus urticae and Bemisia tabaci in Greece. [PDF]

open access: yesPest Manag Sci
Greek populations of T. urticae and B. tabaci exhibit evolving multi‐resistance, confirmed by bioassays and molecular markers, highlighting the urgent need for evidence‐based resistance monitoring in IPM. Abstract BACKGROUND Pesticide resistance in agricultural pests remains a major barrier to effective and sustainable crop protection.

Pyriproxyfen Disrupts the Ongoing Spermatogenesis Wave in Danio rerio Potentially Mediated by Voltage-Dependent Calcium Channels and Protein Kinase C. [PDF]

open access: yesJ Appl Toxicol
ABSTRACT Pyriproxyfen (PPX) is an analog of the juvenile hormone from insects. Following our previous studies, for the ex vivo short‐term effect, we chose 10−9 M pyriproxyfen to analyze the morphology of spermatogenesis wave cells. In silico docking and ADMET (Absorption, Distribution, Metabolism, Excretion, Toxicity) studies were carried out to ...

Negative Cross Resistance Mediated by Co-treated bed nets: A Potential Means of Restoring Pyrethroid-susceptibility to Malaria Vectors. [PDF]

open access: yes, 2014
Insecticide-treated nets and indoor residual spray programs for malaria control are entirely dependent on pyrethroid insecticides. The ubiquitous exposure of Anopheles mosquitoes to this chemistry has selected for resistance in a number of populations ...

A high-throughput HPLC method for simultaneous quantification of pyrethroid and pyriproxyfen in long-lasting insecticide-treated nets

open access: yesScientific Reports, 2022
Long-lasting insecticide-treated nets (LLINs) play a crucial role in preventing malaria transmission. LLINs should remain effective for at least three years, even after repeated washings. Currently, monitoring insecticides in LLINs is cumbersome, costly,
