“…The mechanism of the physiological selectivity may be related to lower penetration rates of the insecticide through the cuticle, higher degradation rates of the insecticide and target site, as well as the relative insensitivity on natural enemies compared to D. hyalinata (Silva et al, 2016). Considering that lipophilicity is inversely proportional to solubility of essential oil in water, lipophilic compounds usually penetrate into the insect body at higher rates, given the similarity in their cuticles (Kumar et al, 2011;López and Pascual-Villalobos, 2010).…”

“…According to the classification scale of pesticide toxicity to non-target organisms of "International Organization for Biological and Integrated Control of Noxious Animals and Plants/ West Paleartic Regional Section" (IOBC/WPRS IOBC/ WPRS) (Hassan et al, 1994), mortality observed for these non-target organisms is slightly harmful (30-79 %) to them. Thus, the use of A. annua essential oil should follow the principles of ecological selectivity in which a product with toxicity to a non-target organism should be used in order to minimize its contact with this organism (Aguiar et al, 2016;Moreno et al, 2017;Silva et al, 2016). Therefore, it is necessary to avoid the use of A. annua essential oil when the plants are in the flowering stage, as it is when bees visit the plants (Silva et al, 2016).…”

The demand for effective insecticides in pest control with low toxicity to the nontarget organisms, such as natural enemies and pollinators, is increasing steadily. A good alternative for synthetic insecticides is natural compounds, including essential oils (EO). This work assessed toxicity of essential oils extracted from Artemisia annua, A. absinthium, A. camphorata, A. dracunculus and A. vulgaris against the melonworm Diaphania hyalinata (Linnaeus, 1758) (Lepidoptera: Crambidae) larvae, a pest of Cucurbitaceae, and their selectivity for fire ant Solenopsis saevissima (Smith) (Hymenoptera: Formicidae) and jataí bee Tetragonisca angustula (Latreille) (Meliponinae). The plants were grown in a greenhouse with mineral fertilization and were used for EO extraction. The insects in the bioassay belonged to the second instar of D. hyalinata and adult forms of S. saevissima and T. angustula. Essential oil from A. annua induced a high mortality rate in D. hyalinata (96 %) over a 48 h period. The same essential oil was selective for predator S. saevissima (42 % mortality) and pollinator T. angustula (74 % mortality), while causing high mortality in D. hyalinata. The insecticidal activity of A. annua oil was attributed to the synergism of its constituents viz., camphor and 1,8-cineole. Therefore, this essential oil contains constituents that are promising for effective use as insecticide due to its high toxicity and rapid action against D. hyalinata as well as low toxicity for predator and pollinator.

“…Garlic extract tested in laboratory conditions in a closed space (Petri dishes), along with 5 other botanical extracts, has shown one of the weakest negative effect on survival of the predatory ant Paratrechina sp. [43]. Reducing the occurrence of ants under the influence of garlic extract may also be associated with the limiting effect of this preparation on the occurrence of aphids (both groups of insects are positively correlated [44]).…”

Impact of Nonchemical Protection of Broad Bean on Epigeic and Soil Arthropodofauna—Analysis in Field-Realistic Conditions

Plant protection methods, even those considered as safe for the environment and consumers, may have unexpected effects on nontarget organisms. The effect of broad bean protection, using Pythium oligandrum, paraffin-coated garlic pulp, and extract from grapefruit seeds and pulp on the abundance of epigeic and soil arthropodofauna in a 3-year field experiment was estimated. The effect was compared with chemical protection, which served as the reference to the conventional system. Use of nonchemical products did not affect the overall abundance of the studied arthropods such as Arachnida (except Acarina), Carabidae, Staphylinidae, and Collembola. These methods, however, may favor Formicidae. In comparison to chemicals (carboxin, mancozeb, deltamethrin, and alpha-cypermethrin), nonchemical preparations seemed to be safer for soil mites—they limited their abundance to a lesser degree. Some individual carabid species showed differing responses to the applied protection methods: Amara aenea occurred only in nonchemically protected areas, Platynus assimilis tends to prefer broad beans protected solely with P. oligandrum, while Anchomenus dorsalis prefer plots protected chemically (seed treatment and 3-time spraying). This may be the effect of the different shading of the soil surface as a result of the influence of protection measures on plant growth. Other explanations may include different vulnerability of species to preparations as well as indirect reaction to the occurrence of other taxa (reduced competition and impairment of food sources) or hormesis.

Faced with the serious consequences resulting from the abusive and repeated use of synthetic chemicals, today rethinking crop protection is more than necessary. It is in this context that the essential oils of the Lamiaceae Ocimum gratissimum and Ocimum canum, the Poaceae Cymbopogon citratus and nardus and a Rutaceae Citrus sp. of known chemical compositions were experimented. The evaluation of the larvicidal potential of the essential oils was done by the method of topical application of the test solutions, on the L1−L2 stage larvae from the first generation of S. frugiperda obtained after rearing in an air‐conditioned room. Lethal concentrations (LC10, LC50 and LC90) were determined after 48 h. After assessing the larvicidal potential of essential oils, molecular docking was carried out to study protein‐ligand interactions and their propensity to bind to insect enzyme sites (AChE). The essential oil of O. gratissimum was the most effective with the lowest lethal concentrations (LC10=0.91 %, LC50=1.91 % and LC90=3.92 %). The least toxic oil to larvae was Citrus sp. (LC10=5.44 %, LC50=20.50 % and LC90=77.41 %). Molecular docking revealed that p‐cymene and thymol from O. gratissimum essential oil are structurally similar and bind to the AChE active site via predominantly hydrophobic interactions and a H‐bond with Tyr374 in the case of thymol. The essential oil of O. gratissimum constitutes a potential candidate for the development of biological insecticides for the fight against insect pests and for the protection of the environment.
