Influence of nitrogen on Leptinotarsa decemlineata

The influence of nitrogen on the performance of Leptinotarsa decemlineata (EPPO A2 pest) on tomatoes was studied in Ontario, Canada. Tomato plants were fertilized with different dosages of nitrogen and the activity of the Colorado beetles feeding on this plants was assessed.
The insects which were feeding on the plants receiving more nitrogen had a significantly higher survival rate from first instar to adult and had a significantly more rapid insect development and greater pupal mass.
