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.

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.

Opis:: 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.

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 this study was to determine the effect of water extracts from dry and fresh matter of Artemisia absinthium L. on feeding of Leptinotarsa decemlineata Say. L2 stage larvae. Dried extracts were prepared in concentrations of 2%, 5% and 10%, while the fresh plant in concentrations of 10%, 20% to 30%. Larvae feeding intensity assessment was carried out by dipping leaves of potato in respective solutions of the extracts, and then determining the weight of food eaten by larvae, and changes of larvae body weight once a day. In addition, absolute deterrence index and palatability index were calculated. The results of the experiment show that the extracts prepared from both dry and fresh matter at the highest concentrations (10% and 30% respectively) contributed to the greatest reduction of the larvae feeding and significant decreased their body weight. With increasing concentrations of extracts from both fresh and dry matter, their deterrent effect on the tested larvae was usually increasing while the value of palatability index was decreasing.
Celem przeprowadzonych badań było określenie oddziaływania wodnych wyciągów z suchej i świeżej masy bylicy piołunu (Artemisia absinthium L.) na żerowanie larw L2 stonki ziemniaczanej (Leptinotarsa decemlineata Say.). Wyciągi przygotowano w stężeniach 2, 5 i 10% dla suchej masy oraz 10, 20 i 30% dla świeżej masy. Ocena intensywności żerowania larw została przeprowadzona poprzez moczenie liści ziemniaków w roztworach odpowiednich wyciągów, a następnie określenie masy pokarmu zjedzonego przez larwy oraz zmiany masy ich ciała, z częstotliwością raz na dobę. Dodatkowo obliczono bezwzględny wskaźnik deterentności i smakowitości. Na podstawie badań stwierdzono, że wyciągi sporządzone zarówno z suchej, jak i ze świeżej masy w najwyższych stężeniach przyczyniły się do największego ograniczenia żerowania larw oraz spowodowały istotny spadek masy ich ciała. Wraz ze wzrostem stężenia wyciągów z suchej oraz ze świeżej masy najczęściej zwiększało się także ich deterentne oddziaływanie w stosunku do analizowanego szkodnika, a także zmniejszała się wartość wskaźnika smakowitości.
