Influence of weather conditions on damages of some types of sugar maize by frit fly (Oscinella frit L.)

Abstract.

The aim of this thesis was to examine an influence of the weather conditions on prey of frit fly and to evaluate differences between some types of sugar maize for damages made by this pest. The experiment was carried out on nine types of sugar maize, in the Experimental-
-Didactic Unit in Swadzim, in years 2007-2009. The percentage of plants’ damages caused by frit fly was defined in the 6-9 leaves phase each year. Average monthly air temperatures, sums of monthly rainfalls and hydrothermal coefficient K by Selyaninov were used by evaluation. The results proved, that the weather conditions had a significant influence on prey of this pest and damages of sugar maize types were significantly different in the three-year period of the research.

Keywords: maize, pest, air temperature, rainfalls, hydrothermal coefficient K by Selyaninov
