Development of knowledge on the biology of western corn rootworm (Diabrotica virgifera virgifera)
Project
Project code: 2809HS002
Contract period: 01.05.2009
- 30.04.2012
Budget: 241,631 Euro
Purpose of research: Applied research
'The aim of the project is to develop biological data as a basis for modeling and forecasting the occurrence and optimum control of the western corn rootworm, Diabrotica virgifera virgifera.
In laboratory experiments with different strains from Europe (initially from Hungary and Italy) are worked out in climate chambers biological data. It is determined differences in embryonic development (percentage of eggs without diapause). Determined for different temperatures and humidity will start hatching, 50% slip and slip the end. To investigate the development of the larvae, individual stages in different densities exposed to different temperatures and calculated correlations between biometric values of the larvae, pupae and adult beetles. In non-election or election situations, coupled with chemical analyzes, the influence of soil particle size analysis and soil moisture on the host finding of the larvae. Lack of food for the population dynamics is important. Therefore, in the laboratory larval stages exposed to different periods of starvation, and the number of survivors and their performance. '
