the family of staphylinidae (rove beetles) includes 40000 species and has a world-wide distribution . many species of paederus have been known for a long time as the causative agent of linear dermatitis. paederus beetles are attracted to artificial lights in the evening during the hot and humid summer nights. whenever they are crashed or smeared on the skin they release their toxin called pede...

the search for alternative ways of controlling sericultural pests has led to the investigation of plant sources for naturally occurring compounds which may have insect growth regulatory, feeding deterrency, repellency and confusantcy characteristics. more than 2000 species of the families asteraceae, fabaceae and euphorbiaceae are known that possess some insecticidal activity. plants with insec...

BACKGROUND The worldwide threat of arthropod-transmitted diseases, with their associated morbidity and mortality, underscores the need for effective insect repellents. Multiple chemical, botanical, and "alternative" repellent products are marketed to consumers. We sought to determine which products available in the United States provide reliable and prolonged complete protection from mosquito b...

Background. The worldwide threat of arthropod transmitted diseased, with their associated morbidity and mortality, underscores the need for effective insect repellents. Multiple chemical, botanical, and “alternative” repellent products are marketed to consumers. We sought to determine which products available in the United States provide reliable and prolonged complete protection from mosquito ...

background: malaria and leishmaniasis are two most significant parasitic diseases which are endemic in iran. over the past decades, interest in botanical repellents has increased as a result of safety to human. the comparative effi- cacy of essential oils of two native plants, myrtle ( myrtus communis ) and marigold ( calendula officinalis ) collected from natural habitats at southern iran was ...

Botanical monoterpenes are secondary metabolites present in essential oils produced by plants. Some of them are insect repellents. The bloodsucking bug Rhodnius prolixus Ståhl (Hemiptera: Reduviidae) is one of the main vectors of Chagas disease in the north of South America and some countries in Central America. In this study, we studied the repellence produced by two monoterpenes, menthyl acet...

Background and Aims: Although local plants as mosquito repellents are known and used among the different cultures of Africa and beyond, little effort is done to document about the knowledge, usage pattern and their repellency potential in Ethiopia in general and specifically around Gilgelgibe Field Research Centre, Jimma Zone, Southwest Ethiopia. This study was aimed to assess the ethno botanic...

in last two decades, considerable attempts have been made to introduce new botanical based insecticides. in this study, repellent effects of the essential oils taken from lavandula angustifolia and zataria multiflora on callosobruchus maculatus adults were evaluated. the essential oils were extracted using a clevenger apparatus. bioassays were conducted under 30±1ºc, 60±5% rh and dark condition...

A wide range of insect repellent formulations, as well as active ingredients, are currently registered for use in Australia. While topical repellents are most common, there are also commercial products in the form of wristbands impregnated with botanical extracts that purport to repel mosquitoes. In laboratory tests, wristbands impregnated with peppermint oil were tested against the mosquito Ae...
