| Abstrakt: | Abstract: The aim of this study was to compare the effectiveness of various predators and parasitoids. The effectiveness of these natural enemies was determined by recording the number of aphids killed in 24 hours under standard conditions. For parasitoids, aphids were kept alive and after 24 hours newly mummified aphids counted. The effect of predators was evaluated based on the number of aphids consumed per individual predator per 24-hour period. The aphid was Brevicoryne brassicae (Linnaeus, 1758) (Sternorrhyncha: Aphidae) but the method is equally suitable for assessing the effectiveness of the natural enemies of other species of aphid and host-plants occurring in other ecological zones for use in integrated control. |
