“…Then, these solvents were mixed thoroughly with 5 ml of Nerolidol. For obtaining a stock solution, 90 ml of distilled water was added to each mixture for preparing a concentration of 4.9% Nerolidol, emulsion (Awad et al, 2013). The stock solution was diluted with distilled water in volumetric flasks for preparation of a series of concentrations: 400.0, 200.0, 100.0, 50.0, 25.0, 12.5 & 6.25 ppm.…”

“…Different plant products had been reported to prohibit the fecundity of various insects. For example, treatment of the newly moulted last (5 th ) instar nymphs of the desert locust Schistocerca gregaria with farnesol led to inhibited fecundity (decreased egg-pod production and number of eggs/pod) (Awad et al, 2013). A great reduction in fecundity of the domestic mosquito Culex pipiens had been recorded after treatment of 4 th instar larvae with Saponin (Djeghader et al, 2018).…”

Although Egyptian cotton leafworm Spodoptera littoralis (Boisduval) (Lepidoptera: Noctuidae) is native in Africa, it is distributed throughout the world. It is a serious polyphagous insect damaging more than 90 host plants of economic importance. The objective of the current study was to evaluate the disruptive impact of Nerolidol, a Sesquiterpene compound, on the most important parameters of adult performance and reproductive potential of this insect. The newly moulted larvae of 5 th (penultimate) or 6 th (last) instar larvae fed castor bean leaves previously treated with 7 concentrations of Nerolidol (400, 200, 100, 50, 25, 12.5 & 6.25 ppm) for 24 hr. The most important results could be summarized as follows. Nerolidol exhibited an adulticidal activity only at the higher concentrations. Nerolidol exerted an anti-morphogenic activity against adult moths since some malformed adults were produced at the higher concentrations. Regardless the treated larval instar, Nerolidol induced the successfully emerged adults to live remarkably shortened total longevity and oviposition period, but the pre-oviposition period was generally prolonged. Nerolidol exhibited an inhibitory effect on the oviposition efficiency since the oviposition rate was deleteriously regressed, in a dose-dependent course. Nerolidol caused a disturbance of the reproductive capacity since fecundity and fertility were dramatically prohibited. After larval treatment with Nerolidol, the successfully mated adult females laid eggs with a significantly prolonged incubation period, especially at the higher concentration levels.

“…Two oxygenated monoterpenes esters from A. falcata oil trans-sabinyl formate and tiglate have been reported to have moderate acute toxicity and acetylcholinesterase inhibitory activities [48]. The main constituents of the oil of A. filipendulina (borneol, bornyl acetate, geraniol, 1,8-cineole and farnesol) have earlier been reported as recognized pesticides [53][54][55][56][57][58]. Their insecticidal effect was related with neurotoxic mode of action through anti-AChE effect on enzyme.…”

The essential oil of Achillea grandifolia Friv. was obtained by hydrodistillation of aerial parts of the plant and analyzed with GC-FID and GC/MS techniques. The oil comprised mostly by the oxygenated monoterpenes (76.2 %) with -terpinyl acetate (54.1 %) as main constituent. The monoterpene hydrocarbons were the second major compound group with p-cymene (17.7 %) as the main representative. The essential oil showed free radical scavenging activity against DPPH • radicals (Inh. 52 %) and ABTS +• cation radicals (TEAC 0.62 mM). The oil demonstrated hypoglycemic activity via inhibition of -amylase (IC50 0.15 mg/mL). The effect of the oil on neurodegenerative disease was expressed via inhibition of acetylcholinesterase (AChE) and found to be > 82 % of inhibition (an IC50 of 1.77 mg/mL).

“…Medically, Farnesol has been reported to regulate the inflammatory responses and has a beneficial effect with edema, allergic asthma, gliosis, skin tumorigenesis, colon oncogenesis, and the immune response system (Chaudhary et al, 2009;Qamar et al, 2012;Santhanasabapathy et al, 2015). Farnesol is a natural pesticide for mites and several insects (Awad et al, 2013;Schulz, 2013). Awad (2012) reported that Farnesol showed a significant dose-dependent increase in mortality on the 4 th larval instar of Agrotis ipsilon.…”

Egyptian cotton leafworm Spodoptera littoralis (Boisduval) is a dangerous pest of many field crops and vegetables in the world. The present study was conducted to evaluate the toxicity of Farnesol and its effects on the growth, development, and morphogenesis of this insect. The newly moulted larvae of 5 th (penultimate) or 6 th (last) instar larvae were fed on castor bean leaves previously treated with 7 concentrations of Farnesol (400, 200, 100, 50, 25, 12.5 & 6.25 ppm) for 24 hr. The most important results could be summarized as follows. After treatment of 5 th or 6 th instar larvae with Farnesol, various mortalities were recorded among larvae, pupae, and adults. Depending on LC 50 values, Farnesol exhibited stronger insecticidal activity after treatment of 6 th instar larvae (LC 50 = 33.67 ppm) than after treatment of 5 th instar larvae (LC 50 = 36.56 ppm). Farnesol caused a serious reduction of larval weight gain and deleterious regression of the growth rate. The larval and pupal durations had been remarkably prolonged, in a dose-dependent course. Disruption of the developmental program was recorded as a failure of ecdysis after treatment of 5 th instar larvae and production of larval-pupal intermediates, regardless the treated larval instar. Farnesol exerted considerable suppressing action on the pupation. At higher concentrations, Farnesol interfered with the adult emergence, since eclosion was completely prevented at the highest concentration and partially blocked at other concentrations. Irrespective of the treated larval instar, some deformed pupae were developed only at higher two concentrations of Farnesol.
