Pulicaria incisa (Lam) is a wild-growing plant in Morocco and has been traditionally used by farmers to control pests of stored grains. The present study was conducted to investigate the chemical composition and insecticidal effect of the essential oil of P. incisa against Sitophilus oryzae (L.) and Tribolium castaneum (Herbst.) by different methods (contact, fumigation and ingestion). The aerial parts of the plant were subjected to hydrodistillation using a Clevenger-type apparatus. The essential oil composition was analyzed by gas chromatography (GC) and mass spectrophotometry (MS). Sixty-six compounds representing 89.4% of total oil were identified. The main components were α-Ocimene (15.17%), τ-Cadinol (6.79%), α-Cadinol (4.51%), Alloaromadendrene (4.45%) δ-Cadinene, (+) - (4.13%). The repellant toxicity test results revealed a higher repellency effect in S. oryzae than T. castaneum. Lethal concentration (LC50), varied between 15.49 - 1.73 μL/cm2 and 20.89 - 2.29 μL/cm2 respectively. In the fumigation test, adults of S. oryzae and T. castaneum were sensitive to the essential oil with LC50 values varying between 16.21 - 2.08 and 18.62 - 2.51 μL/L air. In addition, experiments have shown that the ingestion method is the most toxic towards both insects with LC50 values of the order of 12.59 - 1.51 μL/g for S. oryzae and 14.12 - 2.39 μL/g for T. castaneum. While the lethal time (LT50) values decreased with increasing essential oil concentration, and in all cases, the increased susceptibility of both insects was directly associated with oil concentration and exposure time. This study aims to valorize medicinal and aromatic plants of the Moroccan flora in order to find novel bio-insecticidal products. Furthermore, the study reports for the first time the insecticidal activity of P. incisa against adults S. oryzae and T. castaneum.

Abstract Stored grains are threatened by several insects, leading to losses in quality and quantity. Several studies have revealed the risks of using chemicals that can cause serious health problems for humans. It is in this perspective that the objective of our work should be seen: It was to assess the effect of the essential oil and leaf powder of Mentha pulegium against Sitophilus oryzae and Tribolium castaneum adults attacking post-harvest cereals. The insecticidal activity of the essential oil against these two insects was evaluated by three methods: contact, inhalation and ingestion. The ingestion method was used in the case of the leaf powder. The essential oil and leaf powder of Mentha pulegium exhibited insecticidal activity against Sitophilus oryzae and Tribolium castaneum adults (Mentha pulegium essential oil caused up to 100% mortality of both insects). Both insects were influenced affected by the dose, exposure time and the method by which the insecticidal activity of the essential oil was demonstrated. Adults of Sitophilus oryzae were more sensitive to different concentrations of essential oil and leaf powder than those of Tribolium castaneum. The essential oil has no effect on the germination rate of soft wheat grains (Triticum aestivum). On the contrary, it acts positively by reducing the damage caused by these major stock pests. The data from this study could present an alternative solution for replacing synthetic insecticides for the protection of stored commodities.

The chemical composition of Lippia sidoides essential oils obtained by hydrodistillation was characterized and quantified by GC/MS and their insecticidal activity by fumigation test was assayed against Tenebrio molitor. Moreover, the toxicity of monoterpenes carvacrol, 1,8-cineol and thymol were also evaluated when applied alone or in binary (1:1) or tertiary (1:1:1) mixture. The essential oil of L. sidoides has as major constituents carvacrol (31.68%), ρ-cymene (19.58%), 1,8-cineole (9.26%) and ϒ-terpinene (9.21%), from a 21 compounds identified, being 92.53% of total. Both compounds have insecticidal activity against T. molitor, being the degree of toxicity of carvacrol > 1,8-cineole > L. sidoides essential oil > thymol, and its respectively LC50 at 24h were 5.53; 5.71; 8.04 and 14.71 µL/L air. When the different mixture of carvacrol, 1,8-cineole and thymol was assayed against T. molitor, the synergism among them was observed. For the mixture of carvacrol:1,8-cineole LC50 was 5.34 µL/L air; carvacrol:thymol 7.67 µL/L air; 1,8-cineole:thymol 7.51 µL/L air and carvacrol:1,8-cineole:thymol 6.34 µL/L air. Mainly, the monoterpene thymol had a synergic effect, which increased the toxicity of carvacrol and 1,8-cineole, both in binary mixture like carvacrol:thymol and 1,8-cineole:thymol.

Essential oils (EOs) are mixtures of volatile organic compounds, mostly terpenes, from the secondary metabolism of plants. These oils exert various activities on insects that damage crops and cause losses worldwide for the economy and agriculture. Tribolium castaneum Herbst (Coleoptera: Tenebrionidae) is one of the main pests causing the loss of a large amount of stored food. The objective of this study was to evaluate the volatile chemical composition of the essential oil from Piper gorgonillense Trel. & Yunck. and its repellent and fumigant activity on T. castaneum. The volatile composition was determined with gas chromatography coupled to mass spectrometry. The majority compounds found in the EO were b-caryophyllene (28.7%), a-copaene (13.5%), and d-cadinene (7.3%). The repellency percentages obtained were 78 and 90% at a concentration of 1% with exposure times of 48 and 72 hours, respectively. The fumigant activity refers to the insecticidal action that an essential oil vapor can have without coming into direct contact with insects; this was 100% at a concentration of EO 350 µg mL-1. The results showed that the P. gorgonillense EO had repellent and insecticidal properties for the biological control of T. castaneum.

Abstract Uridine diphosphate glucosyltransferases (UGTs), which are phase II detoxification enzymes, are found in various organisms. These enzymes play an important role in the detoxification mechanisms of plant allelopathy and in insects. Artemisia vulgaris L. (Asterales: Asteraceae: Artemisia) essential oil has strong contact toxicity to Tribolium castaneum Herbst (Coleoptera: Tenebrionidae) larvae. However, the effect of A. vulgaris essential oil on UGTs is unclear. In this study, A. vulgaris essential oil was shown to significantly induce the expression of the TcUgt86Dg transcript. Furthermore, treatment of TcUgt86Dg-silenced individuals with A. vulgaris essential oil resulted in higher mortality than for the control individuals, indicating that TcUgt86Dg is involved in detoxification of A. vulgaris essential oil in T. castaneum. The developmental expression profile showed that the expression of TcUgt86Dg in late adults was higher than in other developmental stages. Furthermore, the expression profile in adult tissues revealed higher expression of TcUgt86Dg in the head, antenna, fat body, and accessory gland than in other tissues. These data show that TcUgt86Dg may be involved in the metabolism of exogenous toxins by T. castaneum; thus, our results have elucidated one possible mechanism of resistance to A. vulgaris essential oil and provide a theoretical basis for a control scheme for T. castaneum.
