Fate of Pyriproxyfen in Soils and Plants [PDF]
Toxics, 2020 Since the 1990s, the insect growth regulator pyriproxyfen has been widely used worldwide as a larvicide in vector control and in agriculture to fight a very large number of pests.

Pyriproxyfen Exposure Impairs Cognitive Parameters and Alters Cortisol Levels in Zebrafish [PDF]
Frontiers in Behavioral Neuroscience, 2020 Pyriproxyfen is one of the most used larvicides and insecticides; it acts as an analog of juvenile insect hormone (a growth regulator). It is highly toxic during all stages of mosquito development, suppresses metamorphosis, and interferes in insect ...

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 ...

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

Must Epidemiologically Impactful Vector Control Interventions Disrupt Mosquito Population Structure? A Case Study of a Cluster-Randomised Controlled Trial. [PDF]
Evol ApplABSTRACT Large epidemiological impacts resulting from disease vector control interventions are typically associated with significant disruption of vector populations. While vector density is a frequently measured response, impacts on demography and connectivity are suspected but rarely quantified.

The Effectiveness of Dengue Vector Control: A Meta-Review. [PDF]
Trop Med Int HealthABSTRACT Background Dengue vector control plays an important role in reducing the burden of dengue infection. This study aimed to summarise the evidence of published systematic reviews on the efficacy of dengue vector control interventions. Methods Systematic reviews of cluster randomised controlled trials and randomised controlled trials in ...

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

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 ...

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.
