To obtain crystal products with ideal morphology and better quality, it is important to fully understand grasp the affecting mechanism of solvents on morphology. In this work, interactions between solvent/solute molecules different faces pyriproxyfen are investigated by a combination experiments molecular simulations. It found that crystals grow into lamellar in methanol ethanol, while grows th...
BACKGROUND MF59, which is an adjuvant belonging to C₃₀ member of the terpene family, is a T helper type-2 (Th2)-biased immune enhancer. Our previous studies showed that pyriproxyfen, a member of the terpene family with fewer carbon atoms (C₂₀) than MF59, enhanced active T helper type-1 (Th1)-biased immune responses. OBJECTIVE This study was performed to investigate the enhancement of antigen-...
We review the current information about causes of microcephaly in Brazil in 2015-6, including speculative ones, in order to provide the best possible clarity about the information that is available as of the publication date. We review the leading candidate, Zika virus infections, the second candidate, the pesticide pyriproxifen, as well as DPT immunizations, and GM mosquitoes. Each of these ca...
The integrated control concept emphasizes the importance of both chemical and biological control for pest suppression in agricultural systems. A two-year field study was conducted to evaluate the selectivity of acetamiprid for the control of Bemisia tabaci (Gennadius) in cotton compared with a proven selective regime based on the insect growth regulators (IGRs) pyriproxyfen and buprofezin. Acet...
A juvenoid insect growth regulator, pyriproxyfen (Nylar or Sumilarv), in a 10% emulsifiable concentrate (10 EC) and a granular (3% sand granules) formulation was evaluated for efficacy against natural populations of chironomid midges in man-made ponds in central Florida. Both formulations at 0.05 kg AI/ha induced complete suppression of adult midge emergence for 1 wk. At 0.2 kg AI/ha, emergence...
BACKGROUND The auto-dissemination approach has been shown effective at treating cryptic refugia that remain unaffected by existing mosquito control methods. This approach relies on adult mosquito behavior to spread larvicide to breeding sites at levels that are lethal to immature mosquitoes. Prior studies demonstrate that 'dissemination stations,' deployed in mosquito-infested areas, can contam...
The objective of this study was to determine the therapeutic and residual efficacy of a topically applied combination of cyphenothrin (40%) and pyriproxyfen (2%) against the tick Haemaphysalis elliptica and the flea Ctenocephalides felis on dogs. Twelve dogs were infested with 50 ticks 2 days before they were treated and with approximately 100 fleas 6 days before treatment and again 2 days befo...
