House flies are global pests and notoriously difficult to control. Essential oils of vetiver, cinnamon, and lavender and their blends were tested for toxic and repellent effects against larval and adult flies. All of the oils had moderate toxicity for eggs. Mortality of 2nd instar larvae was 57–78% in dipping assays, 38–100% in contact assays, and 94–100% in treated media. Lavender was less effective (38% mortality) than the others (91–100%) in contact bioassays. Oil blends were not more effective against larvae than individual oils. Vetiver and cinnamon oils were strongly repellent (84 and 78%, respectively) for larvae in treated media. None of the oils were repellent for adult house flies in olfactometer assays, but testing of additional products demonstrated significant repellency for neem oil, p‐menthane‐3,8‐diol (PMD), and vanillin. Contact/fumigant toxicity of vetiver, cinnamon, and lavender oils was 100%, significantly higher than mortality from sunflower oil (67%). Blends of oils were not more effective against adults than the individual oils, but blends diluted with sunflower oil were as effective as the individual oils. Essentials oils of vetiver and cinnamon may have potential for fly management in situations where conventional insecticides cannot be used.

“…The essential oil of C. cyminum has been extensively explored for its antioxidant and antimicrobial activities [92,93], but most of the investigations focused only on the bioactivities of the essential oil and have seldom considered what is the most responsible component for its specific bioactivity. Although synergy was a popular account of the essential oil bioactivities [94,95], overemphasizing synergy is not useful for the elucidation of the mode of these bioactivities and consequently, for the development of more effective remedies. Since the preciousness of natural-derived essential oils makes it financially unfeasible to practically use them to achieve the desired effects, the investigation of the function mechanisms of their bioactive components is of practical significance, so that some low cost alternatives can be developed.…”

Cuminal Inhibits Trichothecium roseum Growth by Triggering Cell Starvation: Transcriptome and Proteome Analysis

Trichothecium roseum is a harmful postharvest fungus causing serious damage, together with the secretion of insidious mycotoxins, on apples, melons, and other important fruits. Cuminal, a predominant component of Cuminum cyminum essential oil has proven to successfully inhibit the growth of T. roseum in vitro and in vivo. Electron microscopic observations revealed cuminal exposure impaired the fungal morphology and ultrastructure, particularly the plasmalemma. Transcriptome and proteome analysis was used to investigate the responses of T. roseum to exposure of cuminal. In total, 2825 differentially expressed transcripts (1516 up and 1309 down) and 225 differentially expressed proteins (90 up and 135 down) were determined. Overall, notable parts of these differentially expressed genes functionally belong to subcellular localities of the membrane system and cytosol, along with ribosomes, mitochondria and peroxisomes. According to the localization analysis and the biological annotation of these genes, carbohydrate and lipids metabolism, redox homeostasis, and asexual reproduction were among the most enriched gene ontology (GO) terms. Biological pathway enrichment analysis showed that lipids and amino acid degradation, ATP-binding cassette transporters, membrane reconstitution, mRNA surveillance pathway and peroxisome were elevated, whereas secondary metabolite biosynthesis, cell cycle, and glycolysis/gluconeogenesis were down regulated. Further integrated omics analysis showed that cuminal exposure first impaired the polarity of the cytoplasmic membrane and then triggered the reconstitution and dysfunction of fungal plasmalemma, resulting in handicapped nutrient procurement of the cells. Consequently, fungal cells showed starvation stress with limited carbohydrate metabolism, resulting a metabolic shift to catabolism of the cell's own components in response to the stress. Additionally, these predicaments brought about oxidative stress, which, in collaboration with the starvation, damaged certain critical organelles such as mitochondria. Such degeneration, accompanied by energy deficiency, suppressed the biosynthesis of essential proteins and inhibited fungal growth.fungicides to be used for postharvest treatment, reduced efficacy due to the emergence of pathogen resistance to these chemicals, and the growing public concerns over chemical residues in food and the environment have necessitated the seeking of alternative solutions to control the fungal spoilage and to guarantee food safety and consumer health [8].Essential oils (EOs), generally recognized as safe by the US Food and Drug Administration [9], are natural substances with established antimicrobial activities [10,11] and are a candidate instrument for controlling postharvest disease [12,13]. Nonetheless, this candidacy is compromised by the expensiveness of these natural substances due to their generally low yields. However, exploring their mode of actions is valuable to the development of novel alternatives.The multicomponent EOs attribute their mode of act...

“…3,6 Among the strategies adopted, most chemical insecticides attack adult mosquitoes or their larval stages. 5,7 The reduction of the mosquito population is easier in immature stages (larva or pupa). 8 Most soluble pesticides are organophosphates that inhibit the enzyme, causing paralysis and then death of larvae.…”

Cardol-Derived Organophosphorothioates as Inhibitors of Acetylcholinesterase for Dengue Vector Control

Aedes aegypti is the main vector of three neglected tropical diseases: dengue, zika and chikungunya. Dengue is under surveillance by health organizations worldwide due to the risk of epidemics. Since there is no specific treatment for dengue, most studies have focused on preventing the reproduction and/or development of the mosquitoes. We studied the larvicidal activity of five phosphates and phosphorothioates derived from cardol, one of the four main components of cashew nut shell liquid (Anacardium occidentale L.), at different concentrations. The organophosphorothioate derivatives were tested for their in vitro inhibitory potential against acetylcholinesterase (AChE). One compound, Cdl.i-dPS (median lethal concentration (LC 50) = 0.8 ppm), was four times more efficient compared to an important commercial larvicide, Temephos (LC 50 = 3.2 ppm), and showed greater AChE inhibition than its monosubstituted analogue and Temephos.
