I n t e r v e n t i o n o r P r o g r a m : Through the global eradication campaign led by the Carter Center, the United Nations Children’s Fund, the US Centers for Disease Control and Prevention, and the WHO, 20 countries implemented national Guinea Worm Eradication Programs, run through the ministries of health. The primary interventions of the campaign include the provision of safe water (th...

An organophosphorus-resistant strain of Culex quinquefasciatus was pressured with pyriproxyfen for 17 generations. Egg viability began declining in the F7 generation and became lower as the selection process continued; by the F17 generation egg viability was too low to proceed further. Susceptibility tests on larvae of the F5, F10, F15, and F17 generations showed no indication of increased tole...

The crude extracts of fruits of Sapindus mukorossi, leaves of Cestrum nocturnm, Cestrum diurnum, and Asclepias curassavica were tested under laboratory conditions against Aedes aegypti, a vector of dengue and chikungunya, for their larvicidal properties. Bioassay experiments carried out with crude alcoholic extracts of Sapindus mukorossi, Cestrum nocturnm, Cestrum diurnum, Asclepias curassavica...

Oestrus Ovis is a common sheep parasite in the Mediterranean region. This study was carried out in the Ebro River Valley near Zaragoza (northeast Spain) using tracer animals to describe the seasons when infestation is more likely. Based on that information and an analysis of the evolution of the parasite within the host, we suggest the most appropriate time for treatment. Adult instars appeared...

In Argentina, more than 25,000 cases of dengue were reported in the summer of 2009, even in provinces where the disease was formerly absent. We analysed the susceptibility levels to the larvicide temephos in seven populations of Aedes aegypti, the primary vector of dengue, collected during summer 2007/2008, using the susceptible Rockefeller strain as a control. Although no control failures were...

Freeze dried powdered leaves of Cymbopogum citratus (DC) Stapf, Cinnamomum camphor a (L.) Nee & Eberm Ipomoea mauritiana Jacq. famarandus indicus L., Lantana camara L., Myroxylon balsumum (L.) Harm, Citrus aurantium L. and vitex altisima L. were tested against Callosobruchus maculatus under nochoice and choice situations. Under no-choice situation, V. altisima at the rate of 5.0% w/w was highly...
