Research ArticleOpen accessIn the abstractField Evaluation of a Pneumatic Prototype Machine Designed to Control the Colorado Potato Beetle in Potato CropsSaad Almady, Mohamed KhelifiThe Colorado Potato Beetle (CPB), Leptinotarsa decemlineata Say, 1824, is a major insect pest of potato plants. It can greatly reduce potato yields if left uncontrolled. The most effective method of controlling the CPB is to apply chemical insecticides during its life cycle. However, the CPB tends to develop resistance to chemicals. Therefore, its control is difficult. This has prompted … …American Journal of Agricultural and Biological Sciences, Vol. 17, Issue 1 · 26 Dec 2022 · 6,403 accessesView PDFCite
