Observations on the species composition of ground beetles (Coleoptera, Carabidae) were conducted in the years 2008–2009 in the collection of plants of the genus Allium spp. belonging to Laboratory of Plant Genetic Resources in the Skierniewice IW (UTM: DC 45). Ground beetles were collected using the Barber’s soil traps. In the first year of the study were captured a total of 1 277 adults of Carabidae, in the next year 1 197 ones. The most numerous species trapped were: Bembidion properans (Stephens), B. quadrimaculatum (Linnaeus), Harpalus affinis (Schrank).
The aim of presented studies was to assess the effectiveness of insecticide containing flonicamid (pyridinecarboxamide group) as an active substance against Brevicoryne brassice on white head cabbage. Field experiments were carried out at the Research Institute of Vegetable Crops in Skierniewice and a farm belonging to horticultural college in Powiercie in 2009–2010. In the years 2009–2010 in Research Institute of Vegetable Crops in Skierniewice and on the farm belonging to horticultural college in Powiercie were carried out the field experiments on the effectiveness of insecticide containing as an active ingredient – flonicamid, derived from the pyridinecarboxamide group. Flonicamid has a systematic and translaminar activity and gives very good long-term efficiency against pests. This insecticide was used to control B. brassicae on white cabbage at two doses: 0.14 and 0.16 kg/ha and at dose 0.14 kg/ha with adjuvants: Olejan 85 (1.5 l/ha) and Superam 10 AL (50 ml/100 l spraying liquid). Pirimor 500 WG at the dose rate 0.3 kg/ha, was used as a standard compound. Spraying liquids were applied once, when the first aphid colonies were observed on white cabbage plants. The flonicamid used at the doses 0.14 and 0.16 kg/ha showed a very good effectiveness in the brassica plants protection against cabbage aphid. Addition adjuvants did not significantly affect the increase of the efficiency of the studied insecticide.
Field experiments on the effectiveness of a new insecticide containing cyazypyr (cyantraniliprole group) were carried out in Research Institute of Horticulture in Skierniewice, in years 2009 and 2011. The insecticide was used to control second generation of carrot root fly (Psila rosae Fabr.) in carrot crops. The field experiments were carried out in Skierniewice and Powiercie. The tested product was applied at two doses: 0.25 and 0.5 l/ha, using 600 l of liquid spray per ha, as a single spray. Dursban 480 EC, at a dose of 1.5 l/ha was used as a reference product. The results of conducted experiments revealed that the insecticide containing cyazypyr showed a good efficiency, compared to the control combination, keeping the low level of damage of carrot roots at 4.5–21.7% in both locations.
Three cultivars of dill were used for the experiment: ‘Szmaragd’, ‘Ambrozja’ and ‘Herkules’. The sensory quality included analysis of fresh and dry herb of dill (drying at 38 °C). Results of two years of experiments showed that sensory quality of fresh and dry herbs of dill depends on cultivars. In 2011 the best overall quality was found for the fresh dill of ‘Szmaragd’ cultivar analysed after harvest. In 2012 the best results were noted for the fresh dill of ‘Ambrozja’ cultivar. The lowest quality scores of the two years of experiments were observed for the fresh dill of ‘Herkules’. Drying significantly influences the sensory quality of dry herb of dill.
In 2008–2011, the Research Institute of Horticulture in Skierniewice carried out the project No. 1.14 „Prediction the risks caused by pests occurring in vegetable crops” within the framework of the Long‐term Programme „Development of sustainable methods for horticultural production in order to provide high‐quality nutritional and biological of horticultural products and to preserve biodiversity and protect its resources” for 2008–2014. Field experiments were conducted on the utility of pheromone, odour and sticky traps for monitoring main pest species of vegetables: cutworms, carrot fly, cabbage fly and western corn rootworm. The developed methods of monitoring of the pests occurrence will contribute to the determination of optimal dates for their controlling in some vegetables crops.
During the 2011–2012 the research on optimal treatment time to control cabbage root fly on cabbage crops was carried out. The study focused on determining the suitability of allylisothiocyanate-baited traps to control Delia radicum L. on cabbage crops. Treatment time was determined based on a number of captured females. During cabbage harvesting time an analysis of a root damaged caused by cabbage root fly larva was done. The results show a high efficacy of used monitoring system in control of D. radicum on cabbage crops. Flight monitoring method could be useful for control cabbage root fly in Integrated Pest Management.
