“…The susceptibility of O. surinamensis, R. dominica, T. castaneum and T. granarium adults to the essential oil of S. intermedia with 24-h LC 50 values of 8.151, 12.825, 20.489, and 35.612 µL/L, respectively, was distinguished in the present study. The fumigant toxicity of some plant-derived essential oils against O. surinamensis, R. dominica, T. castaneum and T. granarium has been documented in previous studies; it was found that the essential oils of Agastache foeniculum (Pursh) Kuntze, Achillea filipendulina Lam., and Achillea millefolium L. with respective 24-h LC 50 values of 18.781, 12.121, and 17.977 µL/L, had high toxicity on the adults of O. surinamensis [31,[34][35][36]. The adults of R. dominica were also susceptible to the fumigation of essential oils extracted from Eucalyptus globulus Labill (24-h LC 50 [39][40][41].…”

The use of chemical insecticides has had several side-effects, such as environmental contamination, foodborne residues, and human health threats. The utilization of plant-derived essential oils as efficient bio-rational agents has been acknowledged in pest management strategies. In the present study, the fumigant toxicity of essential oil isolated from Satureja intermedia was assessed against cosmopolitan stored-product insect pests: Trogoderma granarium Everts (khapra beetle), Rhyzopertha dominica (Fabricius) (lesser grain borer), Tribolium castaneum (Herbst) (red flour beetle), and Oryzaephilus surinamensis (L.) (saw-toothed grain beetle). The essential oil had significant fumigant toxicity against tested insects, which positively depended on essential oil concentrations and the exposure times. Comparative contact toxicity of S. intermedia essential oil was measured against Aphis nerii Boyer de Fonscolombe (oleander aphid) and its predator Coccinella septempunctata L. (seven-spot ladybird). Adult females of A. nerii were more susceptible to the contact toxicity than the C. septempunctata adults. The dominant compounds in the essential oil of S. intermedia were thymol (48.1%), carvacrol (11.8%), p-cymene (8.1%), and γ-terpinene (8.1%). The high fumigant toxicity against four major stored-product insect pests, the significant aphidicidal effect on A. nerii, and relative safety to the general predator C. septempunctata make terpene-rich S. intermedia essential oil a potential candidate for use as a plant-based alternative to the detrimental synthetic insecticides.

“…These time differences occur due to OEO components' abilities to ingress the insect's body during respiration [20] and penetrate the integument cuticle layers [15], exerting their effect as neurotoxins [17]. Similar effects were investigated in other pests of stored grains exposed to OEO, such as Acanthoscelides obtectus Say (Coleoptera: Chrysomelidae) [53], Anagasta khueniella Zeller (Lepidoptera: Pyralidae) [54] and Rhyzopertha dominica Fabricius (Coleoptera: Bostrichidae) [55]. The rapid effect against T. molitor is another indication of the potential of OEO to protect stored products.…”

Tenebrio molitor is one of the main stored product pests. This study characterized oregano essential oil (OEO) by gas chromatography (GC/FID and GC/MS) and assessed its insecticidal properties against T. molitor. Mortality, survival, respiration, and behavioral response in larva, pupa, and adult of this insect were determined. The major components of OEO were carvacrol (25.6%), p-cymene (12.3%), linalool (8.71%), thymol (7.22%), γ-terpinene (7.21%), caryophyllene oxide (4.67%), α-pinene (2.71%), and eucalyptol (2.69%). OEO caused high contact toxicity in larvae (LD50 = 3.03 µg insect–1), pupae (LD50 = 5.01 µg insect–1), and adults (LD50 = 5.12 µg insect−1) of T. molitor. Survival rates were 100% in larvae, pupae, and adults of T. molitor not treated with OEO, declining to 65–54%, 38–44%, 30–23%, and 6–2% in insects treated with LD25, LD50, LD75, and LD90, respectively. Low respiration rates of T. molitor at different developmental stages was observed after OEO exposure. Additionally, OEO exposure affects behavioral avoidance response and causes repellency in larvae and adults. These findings show that OEO exerts insecticidal and repellent effects against T. molitor, suggesting a potent alternative to synthetic insecticides for controlling the beetle.

“…Origanum vulgare L. (oregano) is an important species due to its antibacterial, antifungal, antioxidant, antiviral and flavoring properties supported by its complex chemical composition. Oregano is a perennial herbaceous species of Mediterranean origin from the Lamiaceae family known and used since antiquity [6][7][8][9][10][11]. Oregano can be used in the development of a sustainable agroecosystem and for the reconstruction of over-cropped land [12].…”

In this paper, we have comparatively analyzed two subspecies of Origanum vulgare (O. vulgare ssp. hirtum and O. vulgare ssp. vulgare) in climatic conditions with higher than usual temperatures from the Institute of Genetics, Physiology and Plant Protection Chisinau, Rep. Moldova. The aim of the research was to study the producing capacity, content, composition of essential oil, as well as the polyphenols content in O. vulgare varieties, their drought testing and the selection of promising cultivars. Seven O. vulgare ssp. vulgare (Ov) varieties and fourteen O. vulgare ssp. hirtum (Oh) varieties were used as the biological material. The essential oil (EO) separated by hydrodistillation was analyzed by GC-MS techniques. The polyphenolic content was assessed using spectrophotometric techniques. The presence of a direct correlation between the content, production of essential oil and content of polyphenols has been highlighted. Thus, the varieties of O. vulgare ssp. hirtum demonstrate a higher content of essential oil than the varieties of O. vulgare ssp. vulgare, while the polyphenol content, on the other hand, is higher for the varieties of O. vulgare ssp. vulgare than for those of O. vulgare ssp. hirtum. This research has resulted in the selection of two varieties, i.e., “Savoare” of O. vulgare ssp. hirtum and “Panacea” of O. vulgare ssp. vulgare.
