“…However, the extract inhibited the AChE activity. Our results were in agreement with those of Mami-Maazoun et al (2017) wich showed that Urginea maritima bulbs extract was able to interfere with Sitophylus oryzae acetylcholinesterase enzyme andexhibited significant inhibitory effect on acetylcholinesterase activity. This inhibition could possibly be due to its high content in phenolic compounds and alkaloids.…”

Halocnemum stobilaceum (Chenopodiaceae) is one of many halophyte plants from Algerian Sahara. In this study, we investigate the phytochemical composition and the insecticidal activity of the crude ethanolic extract of this plant against adults of the red flour beetle Tribolium castaneum (Coleoptera: Tenebrionidae). Te effect of this extract on the detoxification enzyme Glutathione S-transferase (GST) and the neuroenzyme Acethylcolinesterase (AChE) was also investigated. The repellent effect was evaluated, at the concentration of 1000 μg/ insect, using the preferential zone method on blotting paper. The insecticidal effect was investigated by testing 5 doses: 100, 200, 400, 800 and 1000 μg/insect. The obtained results show that H. stobilaceum is very rich in saponins, gallic tannins, flavonoids, antocyans, coumarins and alkaloids. The plant is poor in irridoids. On insecticidal level, the extract tested at dose 1000 µg/insecte has a good repellent effect on adults of T. castaneum. The repulsively rate calculated after two hours of exposure was 60%. The extract was toxic too. Indeed, the five tested doses caused mortalities of 15, 33.3, 41.6, 48.3 and 70%, respectively, after 6 hours of exposure. The highest dose (1000 μg/insect) generated 100 deaths after 96 h of exposure. The LD 50 calculated 24 h after treatment was 225.4 μg/insect. Furthermore, the extract of this plant, at the concentration of 1000 µg/insect, inhibited acetylcholinesterase (AChE) activity. The obtained results suggest that extracts of this plant can be used to protect the stored products against insect secondary pest.

“…Inhibitory effects of AChE were also observed for compounds such as β-pinene and carvacrol, which can be related to their larvicidal activity [21]. Extracts from Urginea maritime bulbs revealed insecticidal effect on rice weevil, as confirmed by the AChE inhibition [22].…”

Considering the vast array of compounds that plants manufacture that help protect them against insects' attacks, plant raw materials are a potential source of future insecticides/larvicides. In this work, volatiles from maritime pine (Pinus pinaster) branches, a pruning residue, were extracted by supercritical carbon dioxide (scCO 2), and also by hydrodistillation for comparison purposes. The volatiles naturally emitted from the pine branches were identified as well. Experimental design results showed higher extraction yields (up to 6%), when scCO 2 density and temperature increased, while the inverse occurred for total phenolic contents (1.2-3.3% GAE, gallic acid equivalents). Emitted volatiles from the branches were mainly α-pinene, β-pinene, β-myrcene, limonene, and βcaryophyllene. In general, the volatile profiles of the scCO 2 and hydrodistillation extracts were quite similar, revealing abietadiene, the precursor of abietic acid, as the main compound. Oxidation inhibitions of ∼42-59% were obtained for the scCO 2 extracts in the β-carotene assay. The acetylcholinesterase inhibitory activity assay revealed the potential of these extracts to have insecticidal/larvicidal activity, with IC 50 values of 2.8-10.7 mg/ mL. Overall, these extracts may be applied in environmentally-safe insect/larvae control strategies, in formulations that benefit from the presence of antioxidants.

“…Similarly, the LC 50 of essential oils of Pimpinella anisum and Ocimum basilicum have demonstrated their interference with AChE activity in S. granarius [25]. Recently, methanolic extract of Urginea maritime at a concentration of 1000μg/ml was found to result in 73.37% inhibition of the activity of AChE in S. oryzae [26]. Also, another finding has confirmed the inhibitory effect of botanicals on the activity of AChE where Chaubey reported that LC 50 of Cuminum cyminum essential oil reduced AChE activity in S. zeamais to 66.90% compared to 31.59% of the control [28].…”

“…AChE is a key enzyme of the cholinergic system regulating the level of acetylcholine and terminates nerve impulses by catalyzing the hydrolysis of acetylcholine [23]. Some botanicals were reported to inhibit AChE activity in some insect pests of storage such as S. oryzae, S. granarius and T. castaneum, but little is known on effects of botanicals in inhibiting AChE activity in S. zeamais [24][25][26][27][28]. This study was carried out to investigate the ability of E. balsamifera, L. inermis, M. hirtus and S. obtusifolia to cause adult mortality, reduce concentration of body protein and inhibit AChE activity in S. zeamais.…”

Laboratory studies were conducted in order to evaluate the toxicity of ethanolic leaf extracts of Euphorbia balsamifera Aiton, Lawsonia inermis L., Mitracarpus hirtus (L.) DC and Senna obtusifolia L. against Sitophilus zeamais Motsch. Ten 7 day old S. zeamais were released in 20g of disinfested sorghum grains treated with ethanolic extracts of the botanicals in plastic bottles at different concentrations of 2.5, 5.0 and 10.0x10 4 ppm at 30°C and 70% RH. Adult mortalities and lethal concentrations that killed 50% (LC 50) of the weevils' population at 24 Hours After Treatment (HAT) were determined. Concentration of body protein as well as inhibition rate of Acetylcholinesterase (AChE) activity in S. zeamais exposed to sorghum treated with the botanical extracts were also investigated. Results showed that the adult mortality ranged from 82.50 ± 2.50 to 100.00 ± 0.00% within 3 Days After Treatment (DAT). L. inermis had the highest LC 50 value (1.72 x 10 4 ppm), while E. balsamifera had the lowest (1.12 x 10 4 ppm). Biochemical tests showed that the botanicals reduced body protein and inhibited the activity of Acetylcholinesterase (AChE) in S. zeamais. The botanicals were found to be toxic to adult S. zeamais and therefore could be utilized to reduce the weevils' infestations in sorghum grains.
