Ефірні олії, як вторинні метаболіти рослин, містять широкий спектр біологічно активних сполук, які можуть впливати на метаболічні, біохімічні, фізіологічні та поведінкові функції комах. Метою даного дослідження було оцінити фумігантну і контактну токсичність ефірних масел деяких видів рослин, що використовуються в кулінарії, порівняти ефективність різної дози та часу експозиції, оцінити різницю між відпрацьованими оліями у відсотках смертності, визначити основні сполуки використовуваних ефірних масел. Біоінсектицидну активність ефірних олій анісу (Pimpinella anisum L.), кмину (Carum carvi L.), фенхеля (Foeniculum vulgare Miller) та материнки (Origanum vulgare L.) досліджували на модельних об’єктах. В якості останніх були обрані імаго довгоносика комірного – Sitophilus granarius L. (Coleoptera: Curculionidae) та личинки хрущака борошняного – Tenebrio molitor L. (Coleoptera: Tenebrionidae). З випробуваних ефірних олій, олія з кмину проявила найвищу біоінсектицидну активність. Модельні організмів по різному реагували на вплив еферних олій. Були уражені лише імаго Sitophilus granarius, натомість личинки Tenebrio molitor не реагували на жодний вид олій, які використовували в тестових випробуваннях. З метою заміщення небезпечних токсичних фумігантів та інсектицидів ефірні олії є можливим інструментом захисту сільськогосподарських культур та продуктів харчування від комах-шкідників, як безпечна альтернатива для людини та довкілля, можуть бути використані в сільському господарстві в системі метоідв інтегрованого захисту від комах-шкідників. Однак, ефективність ефірних олій суттєво залежить від цільових груп організмів, а також способу застосування.

AbstractPhytopathogenic fungi have been responsible for considerable economic losses in vineyards, and therefore, more attention should be paid to the development and implementation of preventative treatment that is environmentally friendly. The aim of this study was to evaluate the antifungal activity of ten essential oils (EOs) (viz. Lavandula angustifolia Mill., Carum carvi L., Pinus mugo var. pumilio, Mentha piperita L., Foeniculum vulgare L., Pinus sylvestris L., Satureja hortensis L., Origanum vulgare L., Pimpinella anisum L. and Rosmarinus officinalis L.). For the antifungal activity evaluation against Penicillium brevicompactum, P. citrinum, P. crustosum, P. expansum, P. funiculosum, P. glabrum, P. chrysogenum, P. oxalicum, P. polonicum and Talaromyces purpurogenus a disc diffusion method was used. The ten EOs exhibited different antifungal properties. Three tested EOs (Carum carvi L., Satureja hortensis L. and Pimpinella anisum L.) at concentrations of 0.75, 0.50, 0.25 and 0.125 µL/mL showed antifungal activity, inhibiting the mycelial growth. The Origanum vulgare L. EOs exhibited a lower level of inhibition. Overall, Lavandula angustifolia Mill., Pinus mugo var. pumilio, Mentha piperita L., Foeniculum vulgare L., Pinus sylvestris L., Satureja hortensis L., Pimpinella anisum L. and Rosmarinus officinalis L. were effective as fungicidal agents but their efficiency varied between the strains of fungi. Carum carvi L. showed strong antifungal activity against all tested strains at both full strength and reduced concentrations. These EOs could be considered as potential sources of antifungal compounds for treating plant fungal diseases.

Measures against pests should be performed in the context of integrated management of agricultural crops and complex control of pests. Therefore, use of ecologically safe approaches is the best option. Essential oils of plants can make an impact on the main metabolic, biochemical, physiological and behavioural functions of insects. We evaluated the effect of 18 essential oils and 18 dried plants on migratory activity of Sitophilus granarius (Linnaeus, 1758) and Tenebrio molitor Linnaeus, 1758 in conditions of laboratory experiment. Notable repellent activity against S. granarius was exhibited by Citrus sinensis and Picea abies. Repellent action against T. molitor was displayed by dried and cut leaves of Origanum vulgare and Eucalyptus globulus, and also essential oils from Juniperus communis, Р. abies, Pterocarpus santalinus, C. sinensis and C. aurantiifolia. Therefore, out of 18 studied essential oils, only two samples had a notable biological effect on migratory activity of S. granarius and five samples – on T. molitor. These data indicate a possibility of using essential oils or their main components as ecologically safe natural repellents against pests of stored wheat and products of its processing.

Hexane Extracts

Spices are a part of the plants used for many purposes as preservatives and as colorants in foods or as medicinal intention. Main aim of the present research was to estimate the potential antimicrobial activity of some spices from Apiaceae family such as Amni visnaga (Diş otu, Hıltan), Anethum graveolens (Dereotu), Apium graveolens (Kereviz), Coriandrum sativum (Kişniş), Cuminum cyminum (Kimyon), Daucus carota (Havuç), Foeniculum vulgare (Rezene), Petroselinum sativum (Maydanoz), Pimpinella anisum (Anason). Thus, the fruits of the plants are used in the experiments. The fruits have been extracted by n-hexane, and all extracts have been subjected to TLC (Thin Layer Chromatography). The n-hexane extracts were screened for their potential in vitro antibacterial activity against Staphylococcus aureus ATCC 29213, Enterococcus faecalis ATCC 29212, Escherichia coli ATCC 25922, Klebsiella pneumoniae ATCC 13883, Pseudomonas aeruginosa ATCC 27853 and antifungal activity against Candida albicans ATCC 10231 by microbroth dilution method. The hexane extracts of the fruits of Coriandrum sativum, Anethum graveolens, Daucus carota, and Pimpinella anisum did not show antimicrobial activity against tested microorganisms. Except these, the other extracts having MIC values of 2.5-5-10 mg/mL exhibited antimicrobial effect against some tested microorganisms. These results demonstrate that the extracts which have an antimicrobial effect can probably play a role as an antimicrobial agent owing to their nonpolar components which are accumulated to the n-hexane extracts.

Abstract The objective of current study was to determine the chemical constituents and fumigant toxicity of essential oil isolated by hydro-distillation from dry fruit of bitter fennel (Foeniculum vulgare Miller). The chemical composition of the essential oil was assessed by gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS). Constituents of the oil were determined as α-pinene (1.6%) and limonene (3.3%), fenchone (27.3%), estragol (3.9%), and (E)-anethole (61.1%). The fumigant toxicity of the essential oil was tested on larvae of the stored product insect Trogoderma granarium Everts. The mortality of larvae was tested at different concentrations ranging from 31.2 to 531.2 μl/l air and at different exposure times (24 and 48 h). Probit analysis showed that LC50 and LC90 following a 48 h-exposure period for essential oil were 38.4 and 84.6 μl/l, respectively. These results showed that the essential oil from F. vulgare may be applicable to the management of populations of stored-product insects.

O gênero Eucalyptus abrange as espécies arbóreas mais utilizadas para reflorestamento no Brasil. Devido ao seu elevado conteúdo de substâncias secundárias, esperava-se que os insetos não causassem sérios danos ao eucalipto. Contudo, muitos insetos, principalmente os da ordem Lepidoptera, tornaram-se sérias pragas na eucaliptocultura. O predador Podisus nigrispinus Dallas (Heteroptera: Pentatomidae) vem sendo utilizado contra insetos herbívoros tais como Thyrinteina arnobia Stoll (Lepidoptera: Geometridae), principal praga do eucalipto, mas não se têm dados sobre seu estabelecimento em áreas de eucalipto. Dessa forma, o objetivo deste trabalho foi avaliar o potencial reprodutivo e sobrevivência de P. nigrispinus sobre T. arnobia proveniente de eucalipto e larvas de Tenebrio molitor L. (Coleoptera: Tenebrionidae) provenientes de criação massal em laboratório. Os aspectos biológicos de P. nigrispinus foram melhores sobre pupas de T. molitor em comparação aos indivíduos criados sobre lagartas de T. arnobia. Provavelmente, as lagartas de T. arnobia estão seqüestrando as substâncias secundárias das plantas de eucalipto e utilizando em sua defesa contra predadores como P. Nigrispinus, e se estes inimigos naturais não estiverem adaptados a tais compostos, a sua performance no controle da praga e no seu próprio desenvolvimento podem ser afetados negativamente.
