    Opis:
    The objective of this study was to determine the effects of various concentrations of water extracts prepared from the fresh or dry mass of lemon balm on the feeding of Colorado potato beetle larvae in L2 and L4 stages. The extracts from the dry matter were prepared at the concentrations of 2%, 5% and 10% and from the fresh matter at the concentrations of 10%, 20% and 30%. The feeding intensity assessment was conducted by dipping leaves of potato in respective solutions of the extracts and determining the mass of food consumed by larvae, as well as the changes of larvae body weight. In the studies on the olfactory reaction of adult insects, a glass “Y-tube” olfactometer was used. The feeding by L4 larvae of Colorado potato beetle was effectively limited by the extract prepared from the dry matter of lemon balm with 10% concentration. The larvae at L2 stage turned out to be more susceptible to the effects of extracts – the extracts in almost all used concentrations limited the feeding of the studied pest. The body weight gain in L2 and L4 larvae of Colorado potato beetle were effectively limited by the extracts prepared from the dry plants of lemon balm in as low concentration as 5%. However, the effect of extracts prepared from the fresh matter of lemon balm plants was effective in limiting the body weight gain of L4 larvae at the minimum concentration of 20%, whereas for L4 larvae the effective concentration was 30%. The evident deterrent reaction of odour substances originating from lemon balm plants towards the females of Colorado potato beetle was found. The males did not react to the above-mentioned factor.

    Opis:
    The aim of the study was to determine the effect of aqueous extracts of dried chamomille (Matricaria chamomilla L.), in concentrations of 2%, 5% and 10%, and fresh parts of this plant, in concentrations of 10%, 20% and 30% on survival of black bean aphid (Aphis fabae Scop.) on the leaves of broad bean (Vicia faba L.) variety “Bartek” and on feeding of Colorado potato beetle (Leptinotarsa decemlineata Say.) on the leaves of potato (Solanum tuberosum L.) variety “Bellarosa”. In these researches on impact of water extracts from chamomille on mortality of wingless females and larvae of black bean aphid, 15 laboratory’s observations in the 8-hour intervals was made. In the studies of the effects of aqueous extracts of chamomille on the dynamics of Leptinotarsa decemlineata feeding on the potato leaves, 4 laboratory’s observations in 12-hour intervals was made. Observations were carried out in 6 replicates divided into L2 and L4 larvae stages. Aquatic extracts of chamomile limited the survival of black bean aphid larvae and wingless females – the higher the concentration, the stronger the effects of the extract, where young insects were found to be more susceptible. Extracts of the dried plant whose concentration was below 5% and extracts of the fresh plant whose concentration was below 20% were found to be ineffective against black bean aphids. In all the analysed concentrations the aquatic extracts of chamomile were found to be ineffective against L2 and L4 larvae of Colorado potato beetle.

    Opis:
    The objective of this study was to determine the effects of various concentrations of water extracts prepared from the fresh or dry matter of lemon balm on Sitona lineatus L. and Aphis fabae Scop. behaviour. The assessment pertaining to the feeding intensity of beetles was carried out by measuring the surface of feeds caused by S. lineatus. While examining the effect of extracts on A. fabae, the mortality of wingless female and aphid larvae was determined. In the studies on the olfactory reaction glass olfactometer "Y tube" and 4 armed arena olfactometer were used. The results of the experiment showed that the water extract prepared from dry matter of lemon balm with 2% concentration limited the feeding of both female and male of S. lineatus. The increase in the mortality of the black bean aphid females and larvae was obtained only after applying the extracts from fresh and dry matter at highest concentrations. The evident deterrent reaction of the odour substances obtained from the lemon balm plants towards the beetles of S. lineatus, could find application in ecological farms via introducing the plant as an accompanying crop to the main crops. The winged individuals of A. fabae did not react to the abovementioned factor.

    The aim of the experiment was to determine the effect of aqueous extracts of dried sage (Salvia officinalis L.) in concentrations of 2%, 5% and 10%, and the fresh parts of the plant in concentrations of 10%, 20% and 30% on the feeding of Sitona lineatus L. on the broad bean (Vicia faba L.) leaves. The olfactometry response of the pest (response to olfactory stimuli) was also determined in relation to the sage. Extracts of dry and fresh parts of sage reveal the inhibitory effect on feeding of both males and females of pea leaf weevil, the stronger, the higher their concentrations, however, no apparent differences were registered between the analysed sexes. Dry plant extracts in 10% concentrations and 30% extracts of fresh sage parts caused 2–3 time reduction of Sitona lineatus feeding after 4 days of the experiment. An apparent repellent response of aroma substances originating from sage towards weevil beetles (both males and females) was registered, which suggests potential applications of this plant as a neighbouring plant in mixed stands or, e.g., as a component of border belts.

    The aim of this study was to determine the effect of water extracts prepared from fresh and dry matter of winter savory (Satureja montana L.) on mortality of wingless females and larvae of black bean aphid (Aphis fabae Scop.). The experiment was conducted in the laboratory, in six replicates. Dry extracts were prepared at concentration of 2%, 5% and 10%, while the fresh plant at concentration of 10%, 20% and 30%. Stomach poisoning of extracts was determined by soaking broad bean leaves in the respective solutions, and then determining mortality of wingless female and larvae feeding on leaves thus prepared at 12 hour intervals. The results of the experiment showed that the extract prepared from dry matter at the highest concentration (10%), as well as the extracts from fresh matter at concentration of 20% and 30% contributed to an increase in mortality of wingless female of black bean aphid. Meanwhile, extracts prepared from both dry and fresh matter at two highest concentrations caused an increase in mortality of larvae of this pest. Furthermore, with increasing concentrations of analysed extracts prepared from both fresh and dry matter of winter savory, their negative effect on wingless females and larvae usually increase.

    The aim of the study was to determine the effect of aqueous extracts of dried mint (Mentha piperita L.) in concentrations of 2%, 5% and 10%, and fresh parts of this plant, in concentrations of 10%, 20% and 30% on feeding of pea leaf weevil (Sitona lineatus L.) and survival of black bean aphid (Aphis fabae Scop.) on the leaves of broad bean (Vicia faba L.), variety “Bartek”. In the studies of the effects of aqueous extracts of mint on the dynamics of Sitona lineatus feeding on the beans leaves, 9 laboratory’s observations in 12-hour intervals was made. Leaves injuries on their edge surface caused by adult individuals were measured. Observations were carried out in 6 replicates divided into males and females. In these researches on impact of water extracts from mint on mortality of wingless females and larvae of black bean aphids, 14 laboratory’s observations in the 8-hour intervals was made. Aqueous extracts of dry and fresh peppermint significantly limited the feeding of pea leaf weevil females, and the extracts from dried material were more effective. Extracts from peppermint caused mortality of black bean aphid larvae compared to wingless females to a greater extent, and the higher the concentration of the extract, the more beneficial effect was observed. An extract from dried material at a concentration of 2% was too weak to effectively combat the larvae of A. fabae, while in the case of aphid females, an effectiveness was only demonstrated for the extracts at the highest concentrations, i.e., 10% of dried and 30% of fresh peppermint.

    The objective of the study was to examine the effect of aqueous extracts from fennel (Foeniculum vulgare Mill.) seeds at 2%, 5%, 10% and 20% concentrations on the feeding of peal leaf weevil (Sitona lineatus L.) on broad bean (Vicia faba L.). The experiment was conducted in the laboratory, in six replicates. Feeding intensity assessment was conducted by dipping leaves of broad bean in respective solutions of the extracts and determining the area of broad bean leaves, eaten by pea leaf weevil beetle in the 12 hour intervals. In addition, absolute deterrence index and palatability index were calculated. As a result of the observation no significant limiting effect of fennel seed aqueous extracts on the feeding of the pea leaf weevil females was shown. All of the used fennel extracts had inhibitory effect on the feeding of male S. linetaus and the strongest effect of extracts was observed in the first 36 hours of the experiment. The high values of the palatability index (particularly for the females) with relatively low absolute deterrence index, indicate limited possibilities of the use of aqueous extracts from fennel seeds for the protection against the feeding of the beetles from the genus Sitona.

    Opis:
    The aim of this study was to determine the effect of water extracts prepared from fresh and dry matter of wild thyme (Thymus serpyllum L.) on feeding adults and larvae of Colorado potato beetle (Leptinotarsa decemlineata Say.). The experiment was conducted in the laboratory, in six replicates. Dry extracts were prepared at concentration of 2%, 5% and 10%, while the fresh plant at concentration of 10%, 20% and 30%. Feeding intensity assessment was conducted by dipping leaves of potato in respective solutions of the extracts and determining the mass of food consumed by adults and larvae, and changes of larvae body weight once daily. In addition, absolute deterrence index and palatability index were calculated. The results of the experiment showed that for an efficient limitation of the feeding adult Colorado potato beetles, an extract from dry matter of wild thyme with a concentration of at least 10% should be used. L4 larvae appear to be considerably more susceptible to the effect of T. serpyllum extract. In their case, an efficient limitation of the feeding, as well as body weight gain can be obtained using extracts from both dry and fresh matter, at concentrations of over 5% for dry matter and over 20% for fresh matter. With the increase of extract concentration, the value of the calculated palatability index decreases, and the deterrence index value increases.
