The efficacy of two novel insecticides to control nuisance diptera breeding in sewage biological filters
… The efficacy of the insectgrowth regulator pyriproxyfen and a biological nematode Steinernema feltiae for thecontrol of sewage flies were assessed. Both insecticides targeted primarily Sylvicolafenestralis, but also the chironomids Metriocnemus hygropetricus and Limnophyesminimus. Initial …

The control of nuisance Diptera breeding in sewage biological filters by low frequency dosing and application of the insect growth regulator pyriproxyfen
… and application of the insect growth regulator pyriproxyfen, for the control of sewage filter flies, was assessed. The low dosing frequency trials targeted primarily Sylvicola fenestralis, but also the chironomids Limnophyes minimus and Metriocnemus hygropetricus. The trials of pyriproxyfen …

Developmental Malformations in Zebrafish Caused by Exposure to Environmental Pollutants
… the effects of a widely used insecticide, pyriproxyfen, which is suspected to cause microcephaly. We identified that pyriproxyfen exposure causes significantly smaller heads, smaller midbrains and a prominent gap along the mid-dorsal margin in the brains in zebrafish compared to controls. …

Endocrine control of fat body composition and effects of the insect growth regulators methoprene and pyriproxyfen on the development and reproduction of the Argentinian cockroach, Blaptica dubia Serville (Blattaria: Blaberidae)
… of adult females with another JH mimic, pyriproxyfen (100 μg per treatment) gave similar results than those for methoprene usage. The results show that both JH analogues have a clear ovicidal activity resulting in “sterilization” of the females and can be used as “third generation …

Breaking the MF curse: the regulatory role of the Methyl farnesoate – MEKRE93 pathway in crustacean molting
… lateralis YOs were responsive to JH-mimics (e.g. pyriproxyfen, fenoxycarb, methoprene, and hydroprene), but not to MF. Taken altogether, these data suggest that the YO can respond to MF and may have its own MF-innate system serving as an autocrine factor to regulate the YO by acting through a …

Underlying mechanisms of juvenile hormone (JH) and its analog in regulating mosquito reproduction
… reported that the application of a JH analog, pyriproxyfen (PPF), on adult female mosquitoes substantially reduces their reproduction. A big knowledge gap was the poor understanding of the mechanism underlying this sterilizing effect of PPF. Here, with our customized laboratory setup that …

Hormonal regulation and environmental influences in the reproduction of the butterfly Bicyclus anynana
… on juvenile hormones (JH). Using a JH mimic (pyriproxyfen) and an antagonist of JH biosynthesis (MK-801), reproduction in B. anynana could be successfully manipulated towards either a higher or lower fecundity. Especially early fecundity responded to manipulations. Furthermore, both JH III and …
