Mortality of Watermelon Aphids by Vegetable and Essential Oil with a Chemical Synthetic Product

Plant extracts have historically served as models in the development of human care against agricultural diseases and pests. The production of medicines and the treatment of diseases began with the use of herbs. Following this, the mortality of aphids in the watermelon fields was studied between the synthetic product Malyphos and the essential oil (Oregano) and then vegetable oil (Neem) to compare them in terms of efficacy in mortality and environmental health. Because of this, watermelon seedlings containing many aphids have been taken with various doses of this product and these oils. During the summer when there is a large number of aphids and after a controlled time, we determine the mortality rates of this parasite over time by well-chosen doses of the synthetic product and these oils. This study of mortality between the product Malyphos and these oils (essential and vegetable) made it possible to demonstrate the role of these natural extracts on the limitation of these parasites and their possible use as natural insecticide while preserving the human health and the environment.
