“…The other important compounds extracted usually from hydro/steam distillation include: carvacrol, a-pinene, g-terpinene, linalool, carvenone, and p-cymene. [14][15][16] The fruits of caraway are used extensively as a mild spice and flavoring for culinary purposes in many cuisines. The dried, brown fruits are hard, crescent-shaped achenes, around 2 mm long with five pale ridges.…”

“…To understand the synergistic toxic effect caused by this botanical pesticide, it is necessary to focus on its active ingredients. The main component of orange peel oil is limonene (87.9-92.5%; Njoroge et al 2009), but caraway oil also contains this cyclic monoterpene (1.5-51.3%; Raal et al 2012). A recent study demonstrated that the ventilation in the migratory locust is adversely affected by limonene in its pure form or as the major component of lovage essential oil (Halawa and Hustert 2014).…”

“…Wintergreen oil mainly contains methyl salicylate (97-99.6%; Gurung 2007), which was found to have insecticidal activity against the adzuki bean weevil Callosobruchus chinensis (Park et al 2016). Raal et al (2012) identified carvone (44.5-95.9%) as the main component of Wawrzyniak and Lamparski (2006) found that aqueous extracts of caraway inhibited the feeding activity of the Colorado potato beetle Leptinotarsa decemlineata and its larvae. This suggests that caraway may be responsible for the antifeedant effect found in locusts.…”

Plant oil mixtures as a novel botanical pesticide to control gregarious locusts

For thousands of years, large locust swarms have caused severe problems in agriculture. People fight against current outbreaks by using chemical pesticides or an insect fungus known as Green Muscle™. While chemical pesticides may be harmful for humans and non-target species, the sporulation of the fungus takes a long period of time and requires conditions of high humidity that are not always found in the field. In this study, we tested the toxicity of a linseed oil/bicarbonate emulsion against gregarious desert locusts and screened for plant essential oils that enhance its toxicity. Finally, we combined three essential oils to develop a novel formulation that is effective against the desert and migratory locust species after single spray treatment. Within 24 h, this formulation caused a mean mortality rate of 80% and 100% of desert and migratory locusts, respectively. Its toxicity is based on a synergistic effect resulting from the combination of caraway, orange peel and wintergreen oils. In addition, we tested this botanical pesticide on two beetle species regarded either as alternative or beneficial non-target species. The first species, mealworm beetles, did not suffer from the spray treatment and behaved normally after 8 days. In contrast, 67.7% of ladybird adults died in the same time span. Interestingly, the growth of wheat seedlings was almost unaffected by spraying this botanical pesticide. These results suggest this botanical pesticide can be used as a strong agent against desert and migratory locusts, but needs to be used with care to minimize unwanted side effects on the ecosystem. Keywords Locust swarm • Linseed oil • Essential oils • Mealworm beetles • Ladybird beetles • Pest management • Botanical pesticide Key message • In many countries, locust outbreaks still constitute a big problem for farmers. Current pest management is potentially harmful for humans. • We developed a novel botanical pesticide against locusts that consisted of natural plant oils. • We identified orange peel, caraway and wintergreen oils to be effective against locusts when added to a linseed oil/bicarbonate emulsion. • Our novel botanical pesticide had a synergistic toxic effect. • This formulation is highly effective against two gregarious locust species and is considered harmless for humans.

“…trans-Carveol and b-caryophyllene content in essential oil of caraway usually range from 0 to 0.2% and from 0 to 0.3%, respectively [9] [22], which was similar to what we obtained in the non-stop 135 min HDT (control) treatment (trans-carveol: 0.137% and b-caryophyllene: 0.16%), but the concentrations of transcarveol (0.067 -0.387%) and b-caryophyllene (0.07 -0.237%) were out of range. Collecting oil at each HDT frames can be accounted for trans-carveol and b-caryophyllene for not falling in range previously reported by [9] [22].…”

“…Carvone extracted from caraway seed oil is being commercially used to control sprouting of potato tubers during storage . The specific caraway seed essential oil profile depends not only on the variety and the environment , geographical region , and on the age of the plant , but also significantly influenced by the extraction process . Hydrodistillation was reported to modify the profile of crushed coriander seed essential oil , a plant from the same family as caraway.…”

Caraway (Carum carvi L.) is a medicinal and aromatic plant; its seeds (fruits) are used as spice and they contain essential oils. We hypothesized that by collecting caraway oil at different time points during the extraction process, we could obtain oil fractions with distinct chemical composition. A hydrodistillation time (HDT) study was conducted to test the hypothesis. The caraway seed oil fractions were collected at eight different HDT (at 0 - 2, 2 - 7, 7 - 15, 15 - 30, 30 - 45, 45 - 75, 75 - 105, and 105 - 135 min). Additionally, a non-stop HD for 135 min was conducted as a control. Most of the oil was eluted early in the HD process. The non-stop HDT treatment yielded 2.76% oil by weight. Of the 24 essential oil constituents, limonene (77 - 19% of the total oil) and carvone (20 - 79%) were the major ones. Other constituents included myrcene (0.72 - 0.16%), trans-carveol (0.07 - 0.39%), and β-caryophyllene (0.07 - 0.24%). Caraway seed oil with higher concentration of limonene can be obtained by sampling oil fractions early in HD process; conversely, oil with high concentration of carvone can be obtained by excluding the fractions eluted early in the HD process. We demonstrated a method of obtaining caraway seed oil fractions with various and unique composition. These novel oil fractions with unique composition are not commercially available and could have much wider potential uses, and also target different markets compared to the typical caraway essential oil.
