The researchers studied about the Pesticidal Effect of Kandingkanding (Lantana camara) on cockroaches (Periplaneta americana). Periplaneta americana was the subject which was known to cause typhoid fever, diarrhea, and other fatal diseases worldwide. Specifically, the study aimed to determine the significant difference in the percent mortality of Lantana camara leaf extract, Baygon, and Ethanol. Fifteen Periplaneta americana were used in the experiment for each of fifteen (15) replicates per group (10%, 20%, Positive control, Negative control) for three (3) trials with a total of 200 cockroaches. The study utilized the completely randomized design and was performed in Cebu Doctors' University Research Laboratory.
Results of the study revealed that there was a significant difference in the mortality (%) of Periplaneta americana after exposing them with 10% and 20% concentration of the leaf extract, Baygon and Ethanol at 0.5 level of significance, Chi- square value of 52.941 with 3 degrees of freedom, p<.0.5. The study showed a mortality of 60% for 20% concentration of Lantana camara leaf extract and 44.4% for 10% concentration of Lantana camara leaf extract. The positive control Baygon showed 97.8% mortality while the negative control which was Ethanol showed 24.4% mortality. Mortality only effective in the 20% concentration of Lantana camara leaf extract.
The Lantana camara leaf extract at 20% and 10% concentration manifested pesticidal effects. The household/homeowners, able to use Lantana camara leaf extract as an alternative pesticide; it is cheaper and easy to prepare. Furthermore, it is recommended that testing for higher concentrations of the extract should be used to swiftly kill the cockroaches and that application amount may be reduced (<15 sprays) with the use of higher concentrations.
