The effects of the thermal and pluviometric regime over the adults reserve from the soil of the colorado beetle (Leptinotarsa decemlineata Say) in the climatic conditions from Suceava area
Abstract
In our experiment we observe the autumn and spring surveys. After these surveys we can determine the way in which has evolved the pest during winter and we can quantify the biological reserve from the soil. There were made some surveys on the lots cultivated with corn, barley, autumn wheat and spring mash and potato cultures. The results of the surveys show that in the analyzed winters only 29% were registered significant losses of the hibernate adults. The homogeneity of the values could suggest that during the less cold winters, the biological reserve could be diminished with approximately half from the number of the hibernated adults from the potato cultivated field.
