The pretest availability of 10% sucrose solution and/or partial blood engorgement in Aedes albopictus Skuse significantly influenced mosquito attack rates and the time of repellent protection in laboratory bioassays. In 46 cm L x 38 cm W x 37 cm H cages used in USDA repellent tests, non-blood-fed and partially blood-fed mosquitoes attempted to bite at similar rates. In small cages (5 cm dia. x ...

Malaria is a mosquito-borne infectious disease of humans. It begins with a bite from an infected female Anopheles mosquito and leads to the development of the pre-erythrocytic and blood stages. Blood-stage infection is the exclusive cause of clinical symptoms of malaria. In contrast, the pre-erythrocytic stage is clinically asymptomatic and could be an excellent target for preventive therapies....

INTRODUCTION Pyomyositis, or isolated abscess formation within a skeletal muscle, is a relatively common condition in tropical climates but it is only encountered rarely in temperate zones. CASE PRESENTATION We present a case of non-tropical pyomyositis of the gluteal muscle in a 26-year-old, previously healthy man from the United Kingdom, who initially presented with sciatica-like symptoms w...

Applications of bendiocarb produced a high insecticidal residual effect lasting up to 3 months on the most common indoor house surfaces. No significant decreases in mosquito man-biting rate levels were observed between treated and untreated villages. It was shown that almost equal proportions of intra- and peridomicillary mosquitoes came into contact with the insecticide, indicating that mosqui...

Methods Observation made in diferent subsets of population who had insect and sting allergy (bees, wasps, scorpions, mosquitos parasites etc). 1) Immunocompetent population in the developing world engaged in farming and related activities regularly exposed to all gradient of allergens like dust molds, dander, pets, etc and when they are exposed to insect and mosquito bites, bees and wasps sting...

There are approximately 300 million cases of malaria each year, resulting in 1 million deaths worldwide. Family physicians often encounter patients preparing to travel to malaria-endemic regions. Physicians should have basic knowledge of parasite transmission and malaria prevention. The risk of malaria acquisition is based largely on geographic location and travel season. Most cases occur in su...

The efficacy of commercial insect repellents was evaluated against Aedes albopictus (Skuse) (Diptera Culicidae) by means of arm in cage assays. The tested products included a DEET-based repellent (Off Spray), a commercial preparation of Icaridin (Autan Active), three formulations containing DMP (Helpic, Sandokan Body Gel, and Sandokan Body Spray) and four plant-derived products (Orphea, Senzazz...
