One of the main insect pests attacking the chickpea crops is the African bollworm, Helicoverpa armigera (Hubner) (Lepidoptera: Noctuidae) in Ethiopia. The Laboratory study was done to investigate the efficacy of five botanicals at Guder Mamo Mezemir Campus, Ambo University. The experiment was replicated three times and prepared in CRD Randomized Design. All the botanicals were filtered and strained through cheesecloth and made stock solution mixed with water at 50, 75, and 100 ml/L of water. Botanical crude extracts were sprayed on H. armigera larvae (10 larvae/Petri dish). Post-spray counts were done at 1, 3, 5, and 7th days after spraying of botanicals under laboratory conditions. The result has shown that the botanical efficacy of Carica papaya, Lantana camara, Moringa olifera, Eucalyptus glubulus, and Capsicum sp. caused percent mortality of H.armigera larvae 70.0, 86.67, 90.0, and 93.33%, respectively. Further research must be given attention to the efficiency of botanical products in farmers' fields in the diverse agroecology of the country for further consideration as a part of integrated pest management tools against the targeted insect pests.
