摘要：
The subject of our study was the grain weevil Sitophilus granarius L. In this work based on laboratory research, it has been presumed that lowering environment temperatures can have an effect on emigration and immigration processes, and thus on the spread of this pest. The control culture was conducted at a temperature of 28 degrees C. The environment temperature of the experimental cultures was changed weekly, and consecutively set at: 25 degrees C, 10 degrees C, 21 degrees C and 25 degrees C. In conditions facilitating the migration of adult S. granarius specimens, the lowered temperature of the surroundings reduced the population's migration activity, and a particular drop in female migration activity was observed. Females are more sensitive to the effects of lower temperatures.
