ABSTRACT
Cigarettes are known to be one of the most common solid wastes that are improperly disposed of. There are numerous chemicals contained in the average cigarette butts pose as threats to health, but on the other hand can offer benefits. Nicotine, a chemical contained in cigarettes, has traditionally been used as a natural organic pesticide for hundred of years. Concern about the pollution caused by the improperly disposed cigarette butts and the benefit of the development of botanical pesticides provided the idea about recycling cigarette butts and making use of them as pesticides, The aim of this study was to determine the effectiveness of different brands of cigarette butts was applied to ten mosquito larvae for each brand. Each brand had three replicates, The result showed that the most effective brand of cigarette was Treatment D, was the most effective resulting to 100% mortality, followed by Treatment E at 90% while treatments B and C had 87% mortality only. In conclusion, this study has shown that the discarded cigarette butts could be used as source of botanical pesticide (mainly nicotine) against Aedes aegypti.,
