Abstract: ATERRADO, CHARLENE P. April 2016. Insecticidal and larvicidal activity of yellow bell (Allamanda cathartica L.) and anis (Clausena anisum- olens (Blanco) Merr.) Leaf extracts against common agricultural and household pests. Undergraduate Thesis. Bachelor of Science in Biology, Major in General Biology, College of Arts and Sciences, Cavite State University, Indang Cavite. Adviser: Ms. Sherine M. Cruzate. This study was conducted to determine the insecticidal and larvicidal activity of yellow bell (Allamanda cathartica L.) and anis (Clausena anisum-olens (Blanco) Merr.) leaf extracts against red weaver ants and housefly larvae. Yellow bell and anis were prepared into fresh (100%, 75%, 50% and 25% concentration) and solvent (Distilled water, methanol, petroleum ether and dichloromethane) extracts. These were utilized for bioassay test against red weaver ants (Oecophylla sp.) and housefly larvae (Musca domestica L). Anis or C. anisum-olens (Blanco) Men. was found to be more effective against red weaver ants in fresh extracts (87% relative mortality) compared to yellow bell or A. cathartica L. (79%) after 48- hour exposure. Anis is more effective against housefly larvae in fresh (30%) and methanolic (95%) extracts. Meanwhile, yellow bell fresh extracts did not exhibit immediate toxicity against the test insects but instead, prolonged the life of the red weaver ants by serving as source of nutrients. However, commercially available insecticide (100%) was proven to be still more effective compared to both the plants tested. The optimum concentration and time of exposure of the plants varied in terms of type of extracts, level of concentrations and time of exposures.
