Abstract: YUMUL, ROBESSA SHAYNE ADRADA. " Leaf Extracts of Hagonoy (Chromolaena odorata Linnaeus) and Alagaw (Premna odorata Blanco) As Botanical Pesticide Against Red Weaver Ants (Oecophylla smaragdina Fabricius) " Undergraduate Thesis. Bachelor of Science in Biology. Cavite State University, Indang, Cavite. October 2006. Adviser: Dr. Josefina R. Rint. The study was conducted to assess the efficacy of different concentrations of hagonoy (Chromolaena odorata L.) and alagaw (Premna odorata B.) as botanical pesticide against red weaver ants; to compare their residual toxicity against red weaver ants; and, to assess the feeding behavior of weaver ants exposed to food substrates in botanically treated filter papers. Three methods were used to evaluate the pesticidal properties of the botanical concentrations. These were contact toxicity test, residual toxicity test and the feeding test. The experiment was laid in a Completely Randomized Design with three replications. The experiment was set-up at the Biological Sciences Laboratory in Cavite State University from December to April 2006. The effect of both hagonoy and alagaw leaf extracts on weaver ants were approximately the same. As contact poison, all extract concentrations of hagonoy and alagaw resulted to weaver ant mortality at twenty-four hours after treatment. Both alagaw and hagonoy at pure extract concentration exhibited 100 percent mortality. This did not significantly differ with 75 percent and 50 percent extract concentrations. Residual toxicity test results showed that the effect of the different botanical extracts to weaver ants' mortality was affected by the length of exposure of test organisms. Hagonoy and alagaw at 75 and 50 percent concentrations significantly caused 92 to 100 percent weaver ants' mortality. Feeding test results showed that application of hagonoy and alagaw leaf extracts reduced the feeding behavior of ants by about 50 percent.
