Abstract

The presented studies revealed the usefulness of spruce oil, basil oil, juniper oil and clove oil in monitoring of the occurrence of pea leafminer (Liriomyza huidobrensis Blanchard). While using above mentioned oils on yellow sticky traps, it was found that the number of trapped insects increased significantly. In relation to the control (traps without any addition of aromatic substance), the increase amounted to: 561.33%, 287.95%, 159.74% and 130.77%, respectively.

Abstract

In presented studies not significant effect of the illumination of blue sticky traps with red pulsating light on their effectiveness in the monitoring of the western flower thrips (Franklinie/la occidentalis Pergande) was found. Observed increase of the number of caught imagines on lighted blue sticky traps was not statistically significant in comparison to the control combination (blue sticky traps without any light).

Abstract

The results of experiments showed an effect of magnetized water on the effectiveness of some selected zoocides. The control of red spider mite (Tetranychus urticae Koch) by Ortus 05 SC showed the highest effectiveness with strongly magnetized water, with use of one magnetizer and two semi-rings. On the other hand, the application of Magus 200 SC in combination with magnetized water showed a decreased effectiveness of insecticide. In the control of grain weevil (Sitophilus granarius L.), an increase in the effectiveness was found for the zoocides Talstar 100 EC, Karate 025 EC and Winylofos 550 EC in combinations with strongly magnetized water (three magnetizers or one magnetizer with two rings). In case of Sumi-Alpha 050 EC, high effectiveness of the treatment was obtained in combinations where water was magnetized in lesser degree, with use of one or two magnetizers. No significant differences were found in the effect of magnetized water on germination of bean (Phaseolus vulgaris L.) and cuckoo flower (Cardamine amara L.) plants.

Abstract

On the basis of the presented studies, it was established that seed dressing by coating protects effectively onion crops against onion fly (Hylemyia antiqua Meig.). In all seed dressing treatments, a significant decrease of number of dam- aged plants was found in comparison to the control. The highest efficacy in protection of onion against onion fly was shown in the case of insecticide Super Homai 70 DS. The effectiveness of this seed dressing reached 80.40% in the year 2001 and 85.44% in the year 2002.
