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...

A synthetic biology approach to the rational design of analogues of olfactory ligands by providing unnatural substrates for the enzyme synthesising (S)-germacrene D, an olfactory ligand acting as a plant derived insect repellent, to produce novel ligands is described as a viable alternative to largely unsuccessful ligand docking studies. (S)-14,15-Dimethylgermacrene D shows an unexpected revers...

Repellent use is one of the most effective personal protection measures in reducing bites of blood-sucking insects/ arthropods and preventing vectorborne disease transmission. Tmditionally. discovery of new repellents involves initial screening of thousands of candidates using various methods with very few successes. However. despite the obvious desirability of finding an effective mosquito rep...

Nutmeg leaf, lemongrass, and bee nests contain bioactive compounds that have potential as mosquito repellents. The purpose of this study was to learn about the bioactivity a combination extract nutmeg nests, well determine efficient repellent lotion recipe from extract. maceration process used for extraction. Total flavonoid content estimated by comparing it quercetin. absorbance value measured...

The effect of insect vectors on avian exposure to infection by pathogens remains poorly studied. Here, we used an insect repellent treatment to reduce the number of blood-sucking flying insects in blue tit Cyanistes caeruleus nests and examined its effect on nestling health status measured as body mass, nestling phytohaemagglutinin (PHA) response and blood parasite prevalence. We found that (i)...

Linalool is a natural plant-product used in perfumes, cosmetics, and flavoring agents. Linalool has proven antimicrobial and insect-repellent properties, which indicate it might be useful for control of enteropathogens or insect pests in poultry production. However, there are no published reports that linalool may be safely administered to or tolerated by chickens. Linalool was added to the die...

N,N-Diethyl meta Toluamide (DEET) is an insect repellent agent that contrary to its benefits,if is used in formulations with high skin permeation, will produce side effects of differentseverity. This study attempted to achieve a semi-solid DEET containing formulation withgood appearance, sufficient spreadity, suitable viscosity for tube and jar filling, compatible pHwith skin, reasonable stabil...

Plant products have been put to use in a variety of contexts ever since ancient times. The development chemical goods, on the other hand, led decline employment these methods against pests. Recently, there has rise concerns over public health and environmental security, which requires identification natural compounds that potential be utilized insect Mosquitoes are major transmitters illnesses ...
