A comprehensive investigation regarding insecticides' mechanism of action on agriculture- and medically-important insects is an important issue to consider. This study aimed to investigate the insecticidal activity of essential oil of Syzygium aromaticum flower (EOSF) using Drosophila melanogaster as an in vivo insect model platform. EOSF was used as a proof-of-concept natural product since it has been reported to exert insecticide activity on certain harmful insects. EOSF was prepared by the water distillation method, and the essential oil is then used to identify its effects on the mortality rate and the locomotor activity of Drosophila. Our results demonstrated that both males and females of D. melanogaster were succumbed immediately, in a dose-response manner, upon EOSF exposure. A slight discrepancy was evident in the effect of EOSF on the mortality rate of males compared to their females' counterparts, thus delineating the possible sex-dependent effect of EOSF on D. melanogaster. Further, decreased locomotor activity was observed on both male and female Drosophila upon EOSF exposure. Overall, it was concluded that EOSF (10 μl, 100 μl, and 1000 μl concentrations) produced insecticidal activity in D. melanogaster.

The essential oil of Syzygium aromaticum has been widely used in traditional medicine to treat a variety of diseases, including some neurological disorders. This study aims at testing, in vivo, the possible anxiolytic and antidepressant effects, of the Syzygium aromaticum essential oil against chronic manganese chloride (4.79 mg/l) intoxication during the gestation and lactation period, in Wistar rat pups. Wistar rat pups were exposed to manganese via their dams’ drinking water from postnatal day (PND) 1 to (PND) 21. After their weaning, the rats exposed to manganese received injections of essential oil of Syzygium aromaticum (0.1 ml/kg) for 18 days. The level of anxiety, depression and locomotor activity were studied. Locomotor activity (open field test), anxiety (elevated plus maze tests), and depression (forced swimming test) were evaluated. The results of the present study indicate that Manganese exposure induces, on the one hand, impairments of body (p<0.001) and of brain weight (p<0.05). On the other hand, it increases level of anxiety (p<0.05), depression (p<0.001) and locomotor hyporactivity (p<0.001), when compared to control rats. Administration of essential oil of Syzygium aromaticum leads to a reduction in the level of anxiety (p<0.05), of depression (p<0.001) and corrects locomotor hyporactivity (p<0.05) in rats exposed to manganese beforehand. These results suggest that essential oil of Syzygium aromaticum can employ as a natural, protective agent against neuro-toxicity induced by manganese chloride during the gestation and lactation periods.

This study evaluated the insecticidal activity of Gallesia integrifoliaessential oil from fruits, leaves, and flowers against Aedes aegyptilarvae and pupae. The essential oil was obtained by hydrodistillation and characterized by gas chromatography-mass spectrometry. Sulfur compounds represented 95 to 99% of the essential oil from fruits, leaves, and flowers. Essential oil major compounds were 2,8-dithianonane (52.6%) in fruits, 3,5-dithiahexanol-5,5-dioxide (38.9%) in leaves, and methionine ethyl ester (45.3%) in flowers. The essential oils showed high activity against larvae, and low for pupae withLC99.9of 5.87 and 1476.67μg/mL from fruits; 0.0096 and 348.33 μg/mL from leaves and 0.021and 342.84 μg/mL from flowers, respectively. The main compound with insecticide activity is probably n-ethyl-1,3-dithioisoindole, from isoindole organothiophosphate class, found in greater amount in flower and leaf essential oil. The great insecticide activity of G. integrifoliaessential oil suggests that this product is a natural insecticide.

A study on the acaricidal properties of foam soap containing the essential oil ofChenopodium ambrosioidesleaves was carried out onRhipicephalus lunulatus. Four doses (0.03, 0.06, 0.09, and 0.12 µL of essential oil per gram of soap) and a control (soap without essential oil) with four replications for each treatment were used forin vitrotrial. Each replication consisted of 10 ticks in a Petri dish with filter paper impregnated with the foam soap on the bottom. Followingin vitrotrials, three doses (0.06, 0.09, and 0.12 µL/g) and the control in two replications were selected forin vivotest based on mortality rate recorded from thein vitrotrial. Each replication was made up of 10 goats naturally infested with ticks. Results show that soap containing essential oil is toxic toR. lunulatus. Thein vivomortality rate in the control on day 8 was 22.69% whereas the highest dose (0.12 µL/g) killed 96.29% of the ticks on day 8. The LD50of the foam soap containing essential oil was 0.037 and 0.059 µL/g on day 2 in the laboratory and on the farm, respectively. This indicates the potentially high efficiency of this medicated soap on this parasite.

Aims: This study evaluates the inhibitory potential of the clove essential oil (Syzygium aromaticum L.) on phytopathogenic fungi in vitro and on maize seeds. Study Design: The experiments comprised completely randomized designs: Seven treatments with five replicates on in vitro test; and four treatments with five replicates each, on in vivo test. Place and Duration of Study: The work was carried out at the Center for Agrifood Science and Technology of the Federal University of Campina Grande, Pombal, Brazil, from April to May 2018. Methodology: In the in vitro test, the essential oil was incorporated into the PDA (Potato-Dextrose-Agar) culture medium. The treatments comprised five concentrations of the oil (0.0125, 0.025, 0.05, 0.1, and 0.2%), a negative control (0.0%), and a positive control (Tiram). Plates were inoculated with the tested fungi, Fusarium verticillioides, Macrophomina phaseolina, and Macrophomina pseudophaseolina, then incubated for seven days at 27±2°C. The percentage of mycelial growth inhibition (PGI) and mycelial growth rate index (MGRI) were estimated. In the in vivo test, maize seeds (AG1051 hybrid) were treated with the essential oil on concentrations equal or superior to the minimum inhibitory concentration found in the in vitro test, besides the negative and positive controls. The artificial inoculation was carried out in fungi colonies for 32 hours and the seed sanity test was performed. The percentage of seeds infected by the fungus was evaluated after seven days. Results: In vitro conditions, clove oil totally inhibited the mycelial growth of F. verticillioides, M. phaseolina and M. pseudophaseolina at concentrations of 0.05, 0.1 and 0.1%, respectively. At 0.2% concentration significantly reduced the incidence of colonies of fungi M. phaseolina and M. pseudophaseolina in hybrid corn seeds AG 1051. Conclusion: The clove essential oil had a fungitoxic effect on the phytopathogens evaluated, under in vitro and in the treatment of maize seeds.

Background: It is one of the effective ways for pesticide innovation to develop new insecticides from natural products as lead compounds. Quinine, the main alkaloid in the bark of cinchona tree as well as in plants in the same genus, is recognized as a safe and potent botanical insecticide to many insects. The structural modification of quinine into 9R-acyloxyquinine derivatives is a potential approach for the development of novel insecticides, which showed more toxicity than quinine. However, there are no reports on the insecticidal activity of 9Racyloxyquinine derivatives to control Mythimna separata. Methods: Endeavor to discover biorational natural products-based insecticides, 20 novel 9Racyloxyquinine derivatives were prepared and assessed for their insecticidal activity against M. separata in vivo by the leaf-dipping method at 1 mg/mL. Results: Among all the compounds, especially derivatives 5i, 5k and 5t exhibited the best insecticidal activity with final mortality rates of 50.0%, 57.1%, and 53.6%, respectively. Conclusion: Overall, a free 9-hydroxyl group is not a prerequisite for insecticidal activity and C9- substitution is well tolerated; modification of out-ring double-bond is acceptable, and hydrogenation of double-bond enhances insecticidal activity; Quinine ring is essential and open of it is not acceptable. These preliminary results will pave the way for further modification of quinine in the development of potential new insecticides.
