Use of biorational insecticides reduces environmental and health damage caused by conventional insecticides. The leafhopper, Empoasca papayae Oman (Hemiptera: Cicadellidae), is one of the most important pests of papaya (Carica papaya L., Brassicales: Caricaceae), because the insect is a vector of phytoplasmas and rickettsia causing irreversible economic damage. The research aimed to determine the biological effectiveness of biorational products: calcium hydroxide, diatomaceous earth, potassium soap, prepared calcium sulfide broth (calcium hydroxide, wettable sulfur, and water at 1:2:10), Terramax, Terra-oil, Terrax CE, imidacloprid as a positive check, and an absolute check without insecticide, on adult leafhoppers in a laboratory. Each treatment had five replications, randomly placed in a humidity chamber. Terramax and Terrax CE killed more pests, 82.98 and 87.23% at 24 hours, followed by increase to 95.65 and 93.48% at 48 hours, respectively. Terraoil, Quimex 95, and Prevents killed 78.26, 76.09, and 74.64%, respectively, 48 hours after application. Diatomix and calcium sulfide killed only 56.52 and 54.34%, respectively. Terramax, Terrax CE, Terraoil, Quimex 95, and Prevents biorational products can be alternatives to control the leafhopper in papaya.
