Botanical Insecticides for the Control of(Alocypha bimaculata Jacoby)

The performance of botanical insecticides in controlling the leaf beetle (Alocypha bimaculata Jacoby) on the yield of the sesame crop (Sesamum indicum L.) in the soil and climatic conditions of the Mapupulo agronomic post. An experiment was conducted in the 2023/2024 campaign in the fields of the Mapupulo Agricultural Research Center (CIAM), which belongs to the Mozambique Agricultural Research Institute (IIAM). A Causalized Complete Block Design was used, consisting of 4 blocks and 5 treatments based on Margosa, Castor, Eucalyptus, Control and Tobacco.In terms of the efficiency of the botanical insecticides, the Tobacco extracts were observed to have the lowest rate of pest attack and herbivory in their plots, followed by the Margosa extracts, so that the control had the highest number of pests and damage. In the yield variable, the Tobacco extracts obtained an average of 1501.0 kg/ha and the Margosa extracts had an average of less than 992.5 kg/ha.
