Abstract
In the city of Nitra research on Sophora japonica L. seeds in five localities (Výstavná street, Andrej Hlinka avenue, Nábrežie mládeže street – University area, City park, Čajkovsky street) was carried out. The field research was realized in 2010. The seeds were evaluated according to the percentage of damaged seeds, the percentage of healthy and germinating seeds, and the percentage of affected but unhatched individuals. The occurrence of parasitoids was monitored as well. The average sample was weighed in a dried state before and after the hatching to measure the weight difference. Data were evaluated by one-way analysis of variance at 95% significance level. Also the impact of location on the number of damaged and healthy seeds was surveyed. An important part of the research was to characterize the external morphological differences between healthy and damaged seeds before the adult hatching. Potentially healthy seeds, not damaged by the pest, were given into Petri dishes, where the ability of undamaged seed germination was studied. Bruchophagus sophorae Cr. et Cr occurred to a large extent in all selected localities. The total average number of damaged seeds in selected localities was 490. It was found that each locality had germinable seeds able to create a healthy plant. During the research no species of natural pest enemies could be identified.
