Sublethal impacts of essential plant oils on biochemical and ecological parameters of the predatory mite Amblyseius swirskii

Abstract

caution when considered as alternatives to synthetic pesticides, and in combination with A. swirskii. Semi-field and field studies are still required to evaluate the effects on T. urticae and A. swirskii of the essential oils tested in this study, before incorporating them into IPM strategies.

Toxicological and physiological activity of lemongrass and peppermint essential oils on life-table parameters of Oligonychus mangiferus and its predatory mite, Cydnoseius negevi

“…Similar observations have been reported in other studies, where the α-esterase and glutathione Stransferase activity of predatory mite Amblyseius swirskii were signi cantly increased by essential oil of Anethum graveolens (Ghasemzadeh et al 2022). Also, among three populations of the Frankliniella occidentalis, the FA (facility agriculture area) population showed an improved detoxifying enzyme activity including carboxylesterase, glutathione S-transferase, acetylcholinesterase, and the cytochrome P450 enzyme system and increased resistance to six pesticides in comparison to the other two populations (Fan et In this study, lemongrass oil was found to be highly effective as an acaricide against the mango spider mite, O. mangiferus.…”

“…Botanical pesticides such as essential oils have the potential to be used in conjunction with biological control agents. However, before they can be suggested for IPM programs, further research is needed to assess their possible direct and indirect impacts on natural enemies (De Araújo et al 2020; Ghasemzadeh et al 2022). One dependable method of assessing the toxicity of pesticides is by measuring their effect on life table parameters (Forbes and Calow 1999;Li et al 2017).…”

Mediterranean Plants as Potential Source of Biopesticides: An Overview of Current Research and Future Trends

“…The applied protocol was based on transferring third-instar larvae of the fly in glass vials with filter papers impregnated with different dilutions of the essential oils [ 153 ]. Various residual or surface contact bioassays, with certain modifications in their protocols, were used to test the bioactivity of a variety of plant extracts and essential oils against eggs, larvae, and adult specimens of insects and mites [ 70 , 72 , 74 , 82 , 87 , 89 , 90 , 92 , 98 , 102 , 113 , 130 , 147 , 148 , 150 , 154 , 155 , 156 , 157 , 158 , 159 ]. For instance, Erdogan and Mustafa dipped tomato leaf discs into the test solutions instead of pipetting a volume onto their surface and then placed Tuta absoluta larvae on them [ 92 ].…”

“…For that reason, similar bioassays can be executed to assess the safety of the compounds against non-target organisms, such as the ladybug Harmonia axyridis , Eisenia fetida earthworms, the green lacewing Chrysoperla carnea , honeybees, or Trichogramma pretiosum hymenoptera [ 25 , 90 , 108 , 130 ]. Non-target organisms may also include predatory mites, such as the species Amblyseius swirskii , which is widely used as a natural enemy for biological control of small pest species, including mites, thrips, and whiteflies [ 72 ]. Similarly, Pino-Otín and colleagues assessed the ecotoxicological impact of a biopesticide from Artemisia absinthium on the soil microbial communities of the earthworm Eisenia fetida and the plant Allium cepa .…”

“…The lack of standardized methods is often critical, especially in insecticidal or repellency assays where a variety of arenas is being used, with different general setups, dimensions, materials, etc. [ 44 , 70 , 72 , 107 ]. The adaptation of more standardized in situ techniques, such as olfactometers for repellency tests, will facilitate the reproducibility of the results of such bioassays.…”
