Insecticidal proteins and their potential use for Colorado potato beetle (Leptinotarsa decemlineata [Say, 1824]) control

Plants respond to pest attack, among other mechanisms, by producing specific proteins with insecticidal properties. Proteins with toxic effects on insects have also been discovered in many other organisms, especially fungi and bacteria. Due to their biological function, insecticidal proteins represent an important potential in the development of more environmentally friendly plant protection methods. Increasing knowledge about the mode of action of insecticidal proteins and the identification of genes encoding their synthesis enable the breeding of transgenic plants resistant to insect pests and the development of new bioinsecticidal agents. The Colorado potato beetle (Leptinotarsa decemlineata) is one of the most important pests of potato, so the study of such control methods is crucial for the development of sustainable integrated pest management strategies of potato. This review highlights the properties of some groups of insecticidal proteins and their modes of action, and summarizes examples of studies of their use for the control of Colorado potato beetle.
