Pyriproxyfen, villain or good guy? A brief review. [PDF]

Arch Endocrinol Metab
Pyriproxyfen (PPF) acts as a juvenile growth regulator, interfering with normal metamorphosis and blocking the development of insects into adulthood. Although the World Health Organization (WHO) considers the use of PPF at a concentration of 0.01 mg/L as unlikely to pose health risks, recent studies have unveiled potential risks associated with PPF ...

Community effectiveness of pyriproxyfen as a dengue vector control method: A systematic review.

PLoS Neglected Tropical Diseases, 2017
BackgroundVector control is the only widely utilised method for primary prevention and control of dengue. The use of pyriproxyfen may be promising, and autodissemination approach may reach hard to reach breeding places. It offers a unique mode of action (

Over-expression of a cytochrome P450 is associated with resistance to pyriproxyfen in the greenhouse whitefly Trialeurodes vaporariorum. [PDF]

PLoS ONE, 2012
The juvenile hormone mimic, pyriproxyfen is a suppressor of insect embryogenesis and development, and is effective at controlling pests such as the greenhouse whitefly Trialeurodes vaporariorum (Westwood) which are resistant to other chemical classes of ...

Multigenerational effects of the insecticide Pyriproxyfen and recovery in Daphnia magna

Science of The Total Environment, 2023
In the present study, an ecotoxicological approach to the evaluation of the insecticide Pyriproxifen in the crustacean Daphnia magna was done. Acute toxicity tests (48 h), feeding behavior test (5 h) and chronic toxicity test (21 days) were carried out on a parental daphnid generation (F0). Pyriproxifen D.

Effects of Insect Growth Regulators on Mortality, Survival, and Feeding of Euprosterna elaeasa (Lepidoptera: Limacodidae) Larvae

Agronomy, 2021
The potential of insecticides that affect the growth and insect development to control Euprosterna elaeasa was evaluated. Fenoxycarb, methoxyfenozide, pyriproxyfen, and tebufenozide were assessed against E.

Pyriproxyfen enhances the immunoglobulin G immune response in mice [PDF]

Microbiology and Immunology, 2013
ABSTRACTPyriproxyfen is a juvenile hormone mimic of vital importance for insect development with little risk to humans. This study was performed to investigate whether large doses of pyriproxyfen affect the immune response in mammals. Mice were immunized thrice with ovalbumin in 5% ethanol, with or without pyriproxyfen or alum.

A horizontally acquired pantothenate gene drives vitellogenin's benefit to whitefly symbiosis persistence

Insect Science, EarlyView.
This diagram illustrates that the horizontally transferred panBC influences the level and localization of vitellogenin (Vg) by facilitating pantothenate production and juvenile hormone (JH) biosynthesis. In turn, Vg shields symbionts by suppressing autophagic degradation in bacteriocytes.

A Review: Autodissemination of Pyriproxyfen as Novel Strategy to Control Dengue Outbreaks [PDF]

Pertanika Journal of Science and Technology, 2020
The new emergence and re-emergence of arbovirus infections transmitted by Aedes mosquitoes have been spreading across Southeast Asia, Central Africa, United States, tropical Oceania and has become a major of public health concern. These arbovirus diseases were found to have a similar vector, symptoms, and environments.

The Comparative Effectiveness of Vector Control Approaches for Dengue: A Systematic Review and Multilevel Network Meta‐Analysis

Tropical Medicine &International Health, EarlyView.
ABSTRACT Background Dengue vector control plays an important role in reducing the burden of dengue infection. Conventional meta‐analysis can only include interventions that can be directly compared. Hence, this study aimed to compare the effectiveness of all interventions for dengue vector control directly and indirectly through a multilevel Bayesian ...
