Heat treatment. All stages of insects are relatively vulnerable to high temperatures. If it rises just a few degrees above the optimum temperature, development stops and harmful effects occur. Coming up around 50 degrees Celsius the heat kills in a short time. Heat treatment is therefore an obvious control method. Less suspicious effects can be […]
