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

A Possible Link Between Pyriproxyfen and Microcephaly [PDF]
PLoS 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.

PLOS Neglected Tropical Diseases, 2020 Exposure of adult mosquitoes to pyriproxyfen (PPF), an analog of insect juvenile hormone (JH), has shown promise to effectively sterilize female mosquitoes. However, the underlying mechanisms of the PPF-induced decrease in mosquito fecundity are largely unknown.
