Investigating insecticidal and repellent activity of Momordica charantia, Calotropis gigantea and Cordia curassavica against Oebalus poecilus

Oebalus poecilus (paddy bug) is a destructive rice pest in Guyana that currently controlled with synthetic chemical pesticides. Increasing resistance rates and farmer's overuse of pesticides have resulted economic ecological issues for Guyanese farmers. Amid growing concerns, this experiment aimed to investigate the use alternative botanical extracts from leaves Momordica charantia (Baan-Carailli), Calotropis gigantea (Madar-Flower) Cordia curassavica (Blacksage) control paddy bug infestation by testing their efficacy as insecticides on O. poecilus. A completely randomized experimental design hot water extraction method was used prepare leaf experiment. Three different concentrations (6%, 12% 24%) each extract were tested adult stage bugs mortality repellent activity. The results, after 72 hours, recorded revealed all demonstrated insecticidal properties. No toxicity systemic insecticide contact observed, thus implying no effect. At average mortalities (98.62%), (90.25%) (100%). Extracts performed better at 6% 24% when compared. Leaf most effective compared other
