Abstract: LUCERO, GLENDA M. October 1993. "Botanical Control of Bean Lycaenid Catochrysops cnejus(Fab.) Lycaenidae, Lepidoptera'' Thesis, BSA, Crop Protection, Entomology, Department of Biological Sciences, School of Arts and Sciences, Don Severino Agricultural College, Indang, Cavite. Thesis Adviser: Dr. Josefina Rodil Rint. The experiment was conducted at the experiment-al area of the Department of Biological Sciences from March to May 1993. This study aimed to determine the effectivity of neem, lagundi, and marigold against bean lycaenid; to determine the effect of botanical pesticides on the yield of bush sitao; and to find out the effect of these three botanicals on other pests of bush sitao. Twenty percent (20%) extract of plant materials diluted in water were applied at five (5) days intervals on bush sitao plantation. Randomised Complete Block Design (RCBD) was used in this experiment. The number of bean lycaenid eggs were reduced and the oviposition preference of the female butterfly was significantly affected by treating bush sitao with botanical pesticides. The three botanicals were equally effective in repelling the lycaenidae from ovipositing eggs on bush sitao flowers and pods. The pods produced were categorised as damaged and undamaged pods. The number of damaged pods was significantly high on untreated plants. The weight of undamaged pods was found signifi-cantly higher on lagundi treated than the untreated bush sitao pods but not significantly different with neem and marigold treated plants. Twenty percent extract of neem gave the lowest percent of damaged pods (15.21%) per plant of bush sitao followed by lagundi (21.63%) and marigold (20.53%), while control bad the highest percent (32.23%) of damaged pods. The use of botanicals increased the yield of bush sitao from Y9,177.35 to a maximum of Y10,857.85. Aphid population was noted to decrease after botanical application. The three botanicals also have a repelling effect on the aphids.
