Sagepesticides_qc_ca - 2017 - Effets toxiques : pyriproxyfène. Parasites & Vectors 09/03/17 Effectiveness of autodissemination stations containing pyriproxyfen in reducing immature Aedes albopictus populations. Recent outbreaks of chikungunya (CHIKV) and Zika (ZIKV) virus infections have stimulated increased interest in management strategies for vector species such as Aedes aegypti (L.) and Aedes albopictus (Skuse) [1, 2, 3, 4].
The latter species has been reported as the sole vector of CHIKV in explosive epidemics on the islands of La Réunion and Mauritius , and a potential secondary vector of ZIKV . The CHIKV outbreak was caused by a new variant of the virus [Reunion Island CHIKV isolates (CHIKV 226OPY1)] with a single adaptive mutation, an amino acid change from alanine to valine in the E1 glycoprotein which increased the infection and dissemination of the virus in Ae. albopictus [5, 6, 7].
Since there are no vaccines or specific antiviral treatments available for CHIKV or ZIKV, Ae. albopictus surveillance and control is critical for the prevention of outbreaks.

MALARIA JOURNAL 04/03/15 The sterilizing effect of pyriproxyfen on the malaria vector Anopheles gambiae: physiological impact on ovaries development. The effect of PPF on fecundity and fertility has been investigated in several insects but the mechanisms by which PPF interferes with female reproductive outcomes has been overlooked specifically in mosquitoes.
The main goals in the present study were to describe the physiological impact of PPF on ovarian development and explore the sterilizing effects of PPF at various times before blood meals. The results of the present study provided further evidence that tarsal contact with PPF-treated nets sterilized adult females of An. gambiae under laboratory conditions. EFSA 21/08/14 Conclusion on the peer review of the pesticide risk assessment of confirmatory data submitted for the active substance pyriproxyfen. Pyriproxyfen was included in Annex I to Directive 91/414/EEC on 1 July 2008 by Commission Directive 2008/69/EC, amended by Commission Directive 2010/39/EU and has been deemed to be approved under Regulation (EC) No 1107/2009, in accordance with Commission Implementing Regulation (EU) No 540/2011, as amended by Commission Implementing Regulation (EU) No 541/2011.
It was a specific provision of the approval that the applicant was required to submit to the European Commission further studies on aquatic insects and pollinators by 30 June 2012. In accordance with the specific provision, the applicant, Sumitomo Chemical Agro Europe S.A., submitted an updated dossier in July 2012, to address the risk to aquatic insects from Pyriproxyfen and from the metabolite DPH-PYR and to address the risk to pollinators, which was evaluated by the designated RMS, the Netherlands in the form of an Addendum to the Draft Assessment Report. PLOS 07/04/15 Mosquito-Disseminated Pyriproxyfen Yields High Breeding-Site Coverage and Boosts Juvenile Mosquito Mortality at the Neighborhood Scale. Abstract Background Mosquito-borne pathogens pose major public health challenges worldwide.
With vaccines or effective drugs still unavailable for most such pathogens, disease prevention heavily relies on vector control. To date, however, mosquito control has proven difficult, with low breeding-site coverage during control campaigns identified as a major drawback. A novel tactic exploits the egg-laying behavior of mosquitoes to have them disseminate tiny particles of a potent larvicide, pyriproxyfen (PPF), from resting to breeding sites, thus improving coverage.
DAILY STAR 13/02/16 Zika hoax claim: Virus NOT shrinking tots' heads – and doctors may have found 'real cause' HOAX?
: Gustavo Henrique, a baby born with microcephaly, and a pesticide warning sign The World Health Organisation issued a "global emergency" after a worldwide epidemic of the Zika virus was linked to a huge rise in babies being born with abnormally small heads. The UK is busy spraying planes from affected areas to kill the carrier mosquitos, British tourists have been warned against unprotected sex and women have been told to avoid getting pregnant in a bid to halt Zika's spread. Brazil – where more than 4,000 cases of the birth defect called microcephaly have been reported since October – has even faced calls to postpone the Rio 2016 Olympics this summer.
But experts have now cast doubt on the link between Zika and microcephaly. And a bid to wipe out the mosquitos that carry Zika may be making things worse – much, much worse. CAMPAIGN: A city worker drops mosquito insecticide into a water tank Pyriproxyfen targets baby mosquitos – known as larvae.
