The population dynamic of the Colorado beetle (Leptinotarsa decemlineata Say) was studied in Central Italy in 1987–1988 to establish an economic threshold for its control. Statistical analysis allowed a measure of damage done at each stage of development of the pest to be expressed in terms of “day-individuals”. On the basis of the data it is possible to predict that, starting from a density of 1 egg mass per plant, a consequent mean density of 24 L4 it can be expected, that this… CONTINUE READING
