“…Based on the above diverse biofunctions and their potential use in storage pest control, we previously investigated the insecticidal activity of 1‐octen‐3‐ol as a fumigant against the important stored‐product pest Tribolium castaneum . We found that 1‐octen‐3‐ol has comparable toxicity for all developmental stages of T. castaneum , presents repellent activity against T. castaneum , and has the effect of promoting the growth of wheat seeds, 8 which indicates that 1‐octen‐3‐ol may be a candidate fumigant, repellent and grain protectant in the storage environment.…”

“…If the treated wheat products need to be quickly consumed and ingested, it is recommended to set a high ventilation temperature to guarantee safety for food ingestion. 1‐Octen‐3‐ol presents both insecticidal and repellent activity against T. castaneum 8 . If the wheat product is expected to require long storage, it is recommended to set a low temperature to maintain enough 1‐octen‐3‐ol residue to kill and repel insects.…”

BACKGROUND Our previous works indicated that 1‐octen‐3‐ol has promising potential as an alternative grain fumigant. However, aside from its insecticidal efficacy, the presence of 1‐octen‐3‐ol residues in grains must be investigated to assess its food safety profile. RESULTS A convenient and sensitive QuEChERS based GC–MS/MS method was developed to detect residues of 1‐octen‐3‐ol in wheat. The sample pretreatment procedures were optimized. The developed method showed good linearity (R2 = 0.9999) and negligible matrix effects. The limit of detection (LOD) and limit of quantification (LOQ) for 1‐octen‐3‐ol were 0.003 and 0.01 mg kg–1, respectively. Recoveries at spiked concentration levels of 0.01, 0.5, 10, 100 and 200 mg kg–1 ranged from 90.8% to 112.4%, with relative standard deviations (RSDs, n = 5) ranged from 1.2 to 7.5%. In the fumigation process during wheat storage, there were positive correlations between the accumulation rate and fumigation concentration as well as between the accumulation amounts and fumigation time. In the ventilation process, temperature significantly affected the dissipation dynamics of 1‐octen‐3‐ol in wheat, and the t1/2 values at ventilation temperatures of 30 and 5 °C for 0.1 μL mL–1 were 0.16 and 21.80 days, respectively, representing a 136‐fold difference. CONCLUSION Preservers can regulate the ventilation temperature to achieve different goals, with either a long duration period for long‐term storage or rapid dissipation for quick food consumption. This study provides guidance on the reasonable usage of 1‐octen‐3‐ol on wheat and other stored grains. © 2021 Society of Chemical Industry

Most insecticides commonly used in storage facilities are synthetic, an issue that generates concerns about food safety and public health. Therefore, the development of eco-friendly pest management tools is urgently needed. In the present study, a 6% (w/w) Hazomalania voyronii essential oil-based nanoemulsion (HvNE) was developed and evaluated for managing Tribolium confusum, T. castaneum, and Tenebrio molitor, as an eco-friendly wheat protectant. Larval and adult mortality was evaluated after 4, 8, and 16 h, and 1, 2, 3, 4, 5, 6, and 7 days, testing two HvNE concentrations (500 ppm and 1000 ppm). T. confusum and T. castaneum adults and T. molitor larvae were tolerant to both concentrations of the HvNE, reaching 13.0%, 18.7%, and 10.3% mortality, respectively, at 1000 ppm after 7 days of exposure. However, testing HvNE at 1000 ppm, the mortality of T. confusum and T. castaneum larvae and T. molitor adults 7 days post-exposure reached 92.1%, 97.4%, and 100.0%, respectively. Overall, the HvNE can be considered as an effective adulticide or larvicide, depending on the target species. Our results highlight the potential of H. voyronii essential oil for developing green nanoinsecticides to be used in real-world conditions against key stored-product pests.

Due to the several side effects of synthetic pesticides, including environmental pollution, threats to human health, and the development of pest resistance to insecticides, the use of alternative healthy, available and efficient agents in pest management strategies is necessary. Recently, the use of essential oil obtained from aromatic plants has shown significant potential for insect pest management. For this reason, the essential oil isolated from seeds of Thapsia garganica L. was investigated for the first time for its chemical profile, and its toxicity and repellency effects against Tribolium castaneum adults. Qualitative and quantitative analyses of the chemical composition by gas chromatography coupled to mass spectrometry (GC/MS) revealed the presence of 18 organic volatiles representing 96.8 % of the total constituents. The main compounds were 1,4-dimethylazulene (51.3 %) followed by methyl palmitate (8.2 %), methyl linoleate (6.2 %) and costol (5.1 %). Concerning the repellent effect, results revealed that SEO (Seed Essential Oil) was very repellent towards T. castaneum adults, with 100 % repellency after 2 h of exposure. Furthermore, the essential oil exhibited remarkable contact toxicity against T. castaneum (93.3 % of mortality) at the concentration of 10 % (v/v). The median lethal dose (LD 50 ) of the topical application of the seed essential oil was 4.4 %. These encouraging outcomes suggested that the essential oil from T. garganica seeds could be considered a potent natural alternative to residual persistent and toxic insecticides.
