Philipp Lehmann says ecology and evolutionary biology doctoral dissertation, University of Jyväskylä, Finland's potato fields that become the scourge of the Colorado potato beetle food importers is an extremely successful pest.
Philip Lehmann studied the book, the ecophysiological mechanisms related to adaptation to the new light cycle and the length of growing season. The study was a species of the Colorado potato food importers beetle (Leptinotarsa decemlineata), which is spread food importers ecological and evolutionary sense, especially in a short period of time over a large area.
Colorado potato beetle is native to Mexico, where it was the last 150 years passed from human spread to North America, a large part of Europe and deep into Asia. Colorado potato beetle is oligofaaginen herbivore that specializes in eating Solanacae tribe of plants. This family includes many economically important crops, such as potatoes, tomatoes, peppers and eggplant.
Colorado potato beetles overwinter in deep and genetically determined resting phase, food importers diapaussissa. In order to be successful overwintering, Colorado potato beetles are preparing for it in many ways. Diapaussiin individuals preparing for, inter alia, increase their energy reserves by storing triglycerides and lower the basal level in order to reduce food importers energy consumption. In addition to the gonads food importers become inactive.
In the end, the Colorado potato beetles are transferred food importers to suitable wintering. Wintering location beetles bury themselves in the ground to a depth of 20-60 cm, where they are protected from the Earth's surface occurring in rapid temperature and humidity changes. Diapaussin the beginning food importers of the environmental factors affecting the three, the most important is the light cycle. The temperature and quality of food affect behavior.
Lehmann to investigate whether European Colorado potato beetles adapted to the area of environmental seasonal variations (paikallissopeuma), and the factors that could explain the ability of species to colonize large geographic areas. His tutkimiaan environmental factors were the length of the growing season, the length of the winter, the light cycle and temperature.
Lehmann study, the Colorado potato beetle explosion of Europe, it has been possible because of the many stressitoleranssiin food importers phenology and related properties are rapidly changing to meet the new environmental conditions.
