Effectiveness of “bahu-baho” Lantana camara L. leaf extract as alternative larvicide on household mosquito Culex pipiens larvae

The study was conducted to determine the effectiveness of Bahu-Baho Lantana camara L leaf extract as alternate larvicide against mosquito Culex pipiens larvae. It utilized experimental design which has four treatment levels with three replications each. The set-up was the control, 25%, 50% and 75% concentration of bahu-baho leaves extract. Using ANOVA the result showed that there was no significant difference on the mortality of mosquito larvae with regards to the different treatment levels in a given time interval. With the toxicity level of Bahu-baho extract and the given time interval, it further entailed that the shorter the period of time of exposure of mosquito larvae to the concentration of bahu-baho leaves extracts, the higher the level of concentration it required to exterminate the given percentage of mosquito larvae. On the other hand, the longer the time of exposure, the lower the level of concentration needed to achieve the desired lethal dose effect on the larvae.
