| Description | Cultivation of herbicide-tolerant strain of GM corn involves applications of a non-selective herbicide. Mortality of arthropod natural enemies resulting from the application of herbicides is negligible. But nothing is known how herbicides affect the behaviour of natural enemies and thus alter their pest control efficacy. Aim of the study was to assess the effect of the Roundup residues on the predatory, defensive, locomotory and reproductive behaviour of epigeic spiders and carabid beetles. Specimens of Pardosa agricola (Araneae: Lycosidae) and Poecilus cupreus (Coleoptera: Carabidae) were exposed for 2 h to the fresh and 1-day old residues of Roundup Biaktiv (Monsanto, IPA 480 g/l). Predation rate was similar for all treatments in both spiders and beetles. |
