... main bases used were pure petroleum jelly, wax and mineral oil. In this experiment 1ml of the extract was used in 10ml of the base. That is, only the 10% concentration was used in each case. This is because it’s at this concentration that DEET offers 100% activity in the solvent or base.
Repellence Activity of Essential Oils of Lonicera Sp against Anopheles Gambiae Mosquitoes
About a century ago mosquitoes were confirmed to be carriers of malarial parasites, the most serious diseases in the tropics. Over 500 million clinical cases have been reported resulting in 2 million deaths annually.

Anteprima della tesi: Repellence Activity of Essential Oils of Lonicera Sp against Anopheles Gambiae Mosquitoes
Repellence Activity of Essential Oils of Lonicera Sp against Anopheles Gambiae Mosquitoes ABSTRACT Despite the extensive efforts to combat malaria over the past six decades, it still remains a scourge in more than 90 countries inhabited by 40% of the world’s population. Hope for eradication of diseases has been frustrated by a number of challenges such as; emergence of drug and insecticide repellence strains of plasmodium parasites and anopheles mosquitoes respectively, global warming, re-introduction of vectors in areas initially free of malaria and environmental concerns. Alternatively control methods and materials that are effective against the target mosquito species, with minimum detrimental effects on the environment are needed. One of such methods is the application of selected botanical derivatives against the target mosquito species. This involves the use of plant derived repellents, insecticides, larvicides and insect growth regulators. The present study was designed to experiment if flowers of lonicera plant species, from high altitudes areas of Kenya (around Mt. Kenya) exhibit any mosquito repellence activity. The essential oils were extracted by steam distillation of the flowers. The crude extracts were then bio-assayed against the Anopheles Gambiae species of mosquito. The extracts at 10% exhibited an ...... main bases used were pure petroleum jelly, wax and mineral oil. In this experiment 1ml of the extract was used in 10ml of the base. That is, only the 10% concentration was used in each case. This is because it’s at this concentration that DEET offers 100% activity in the solvent or base.
