Abstract

Insecticides are chemicals or biological substances that are used to kill or disable insects. Blood feeding mosquitoes are responsible for the intolerable biting nuisance and transmission of large number of diseases such as malaria, yellow fever, dengue fever, filarias is amongst others, causing serious health problems to humans and obstacles to socioeconomic development of developing nations like Nigeria. The insecticidal effect of scent leaves (Ocimum gratissum) and Ramboâ„¢ paper on mosquitoes was investigated. The study is aimed at comparing the insecticidal effects of Ocimum gratissimum and Ramboâ„¢ paper on mosquitoes in Jos. 100 mosquitoes were exposed to dried Ocimum gratissum and Ramboâ„¢ paper at different time intervals of 5, 10 and 12 min. Results obtained showed a time dependent insecticidal effect on mosquitoes, which was 54.2%, 54.0% and 55.6% total mortality of mosquitoes at respective time intervals on exposures to both Ramboâ„¢ paper insecticide and Osimum gratissum, indicating that there was a significant difference in the lethal effect of Ramboâ„¢ paper insecticide and scent leave on mosquitoes at (p<0.05). In comparing the lethal effect of Ramboâ„¢ paper insecticide and Ocimum grasstisimum on mosquitoes at differnt locations in Jos, at Dogon Karfe, after 10 min of treatment, Ramboâ„¢ paper had the highest lethal effect of 21 (84.0%) compared to scent leaves 6 (24.0%) and at Abattoir Jos, after 12 min of treatment, Ramboâ„¢ paper had the highest lethal effect of 17 (94.4%) compared to Ocimum grasstisimum 3 (16.7%). These comparisons were significant at p 0.05. This study provides evidence that Ocimum grasstisimum has a mosquitocidal effect. However, the Ramboâ„¢ paper gave a better mosquitocidal effect than Ocimum grasstisimum. There is a need to discover better additive or extract options that could give Ocimum grasstisimum a better effect as a natural product available in Africa towards the malaria eradication programme.
