The effects of pyriproxyfen were tested against a local population Aedes aegypti (L.) in Iquitos, Perú. Bioassays showed that, when applied to late instars, prevented adult emergence at extremely low concentrations (LC50 = 0.012 ppb). There was no from water sampled storage tanks that had been seeded with the equivalent 50–83 ppb (AI) pyriproxyfen. Five months after treatment, despite constant dilution these tanks, sources continued be lethal larvae and pupae. Additional studies, carried out...
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 campaigns identified as a drawback. A novel tactic exploits the egg-laying behavior of mosquitoes to have them disseminate tiny particles potent larvicide, pyriproxyfen (PPF), from resting...
Mosquito-borne viruses threaten public health worldwide. When the ratio of competent vectors to susceptible humans is low enough, virus's basic reproductive number (R0) falls below 1.0 (each case generating, on average, <1.0 additional case) and infection fades out from population. Conventional mosquito control tactics, however, seldom yield R0 < 1.0. A promising alternative uses mosquitoes disseminate a potent growth-regulator larvicide, pyriproxyfen (PPF), aquatic larval habitats; this...
Aedes aegypti and Ae. albopictus are the vectors of dengue, most important arboviral disease humans. To date, ecology studies have assumed that truly absent from sites where they not detected; since no perfect detection method exists, this assumption is questionable. Imperfect may bias estimates key vector surveillance/control parameters, including site-occupancy (infestation) rates control intervention effects. We used a modeling approach explicitly accounts for imperfect 38-month, 55-site...
Se reportan las características de los desoves "churo", Pomacea maculata, en acuarios vidrio Iquitos-Perú. utilizaron seis 70 x 40 cm. con un tirante agua 15 En cada acuario se colocaron cuatro "churos" adultos, proporcionándose alimento peletizado tenor 30% proteina total y además hierbas acuáticas: "putu-putu", Eichornia crassipes, "lenteja agua", Salvinia auriculata "huama", Pistia stratiotes. La oviposición realizó paredes internas a una altura 30 cm sobre el nivel del agua. Los...
