Insecticide resistance has been known to be prevalent in several insect species including mosquito. It has become a major problem in vector control programs due to pesticide resistance through detoxification enzymes. The present study aimed to compare between the larvicidal action of some organophosphorus insecticides (fenitrothion, malathion and temephos) commonly used in larval control progra...

The objective of this work was to monitor the susceptibility of malaria vectors to insecticides in nine sentinel sites of the National Malaria Control Program in Mali. The study was performed during the rainy seasons of 2010 and 2011. WHO bioassays were conducted using F0 and/or F1 from wild collected females. The insecticides used were lambda-cyhalothrin 0.05%, DDT 4%, permethrin 0.75%, deltam...

Consumption of pesticide contaminated vegetables pose a major threat to public health. High Performance Liquid Chromatography (HPLC) with a Photo Diode Array detector (PDA) was used to determine two organochlorines (methoxychlor and DDT), seven organophosphorus (acephate, chlorpyrifos, fenthion, fenitrothion, malathion, parathion, and ethion), two carbamate (carbaryl and carbofuran) and one pyr...

We report the resistance to 12 insecticides of specimens of Anopheles sacharovi, both in laboratory cultures and those collected in the malarious areas of Adana, Adiyaman, Antalya, Aydin, and Muğla in southern Turkey. Mortality was higher 24 h after exposure than immediately after exposure but was unaffected by temperature (24 degrees C or 29 degrees C) or the position of the test kit (horizont...

Techniques for the emergency control of adult Aedes aegypti populations and their development are reviewed. Larviciding and environmental measures provide only delayed control of adult populations. Large-scale field trials of the ultra-low volume application of insecticide concentrates in Southeast Asia, South America and Africa, using aerial, ground, vehicle-mounted and hand-carried equipment,...

Context. The field just West of the galactic supernova remnant W28 (l=6.4 o , b=-0.2 o) harbors 3 of 5 newly-discovered 1720 OH maser spots and two recently-discovered candidate supernova candidates (one of which is a γ-ray source), as well as several compact and classical HII regions. Aims. To show the interaction of radio supernova remnants with ambient molecular gas in sky field just West of...
