“…The chemical 1-Hexyl-2-nitrocyclohexane, which has neuroactive, anti-inflammatory, and analgesic properties, is also present in both male and female insects [ 22 , 23 ]. Nonacos-1-ene, a female-specific chemical, is one of the pheromone elements utilized for insect communication [ 24 ], and 2-Heptadecenal, a substance with lipophilic characteristics aids in the production of propolis bee glue is also detected [ 25 ]. Among the unique volatile compounds of male insects, indole has been used as a promising agent for the treatment of antimicrobial activity, malaria, diabetes, cancer, migraines, convulsions, and hypertension [ 26–28 ].…”

Edible insects play an important role in human health and food security. Among those, the Giant water bug, Lethocerus indicus (Lep.& Ser.) is a widely used edible insect known for its aroma, flavor, and therapeutic purposes. In the present study, we investigated the nutritional profile, natural habitat, and feeding behavior of L. indicus in aquarium conditions. A comparative analysis of male and female insects’ aroma contents and fatty acid (FA) profiles was also conducted. A dry fried male insect yielded volatile oil of 0.96%/2 g body weight, whereas a dry fried female yielded 0.48%/5.36 g of body weight. In terms of lipids, fresh male insects had 0.15%/5.42 g of body weight and fresh female insects had 0.28%/9.48 g of body weight. There are 24 volatile compounds specific to males, 37 specific to females, and 13 commons to both were identified. 2-Hexen-1-ol, acetate, (Z)- which smells like banana, was prevalently found in males while 4-Octene, 2,6-dimethyl-, [S-(Z)] was prevalently found in female insects. Fatty acids profile analysis detected 32 FA with 12 unique FA from males whereas 22 FA and 3 unique FA were identified from female insects. The SFA percentage present in males and females was 77.44% and 85.21%. Males had 6.78% MUFA content while females have 4.75%. Males have 18% PUFA content enriched with DHA, and EPA, while females had 10.04%. This study revealed that with the presence of a banana-like smell of volatile compound and more MUFA and PUFA in males, the native people of North-East India preferred male over female insects for entomophagy.

The purpose of this study was to assess volatile component profiles and the antioxidant activity of propolis samples from eight different locations in Türkiye. α‐Pinene, β‐pinene, 3‐carene, limonene, 2‐acetylfuran, benzaldehyde, acetic acid, benzoic acid, longifolene, isopentyl acetate, m‐cymene, styrene, and δ‐cadinene were the most common volatile components found in the most of propolis samples. Principal component analysis (PCA) and hierarchical cluster analysis were performed on the gas chromatography–mass spectrometry (GC–MS) data to identify trends and clusters in the propolis samples. As a result of the PCA, the common components in all propolis were m‐cymene, decanal, α‐pinene, limonene, pinocarvone, benzaldehyde, and butanoic acid. The samples had 2,2‐diphenyl‐1‐picrylhydrazyl radical (DPPH) inhibition activity ranging from 19.2% to 92.5% and 2,2′‐azinobis(3‐ethylbenzothiazoline‐6‐sulfonic acid) (ABTS) values ranging from 480 to 1370 μM trolox/g extract. The total phenolic content (TPC) ranged from 10,900 to 34,033 mg GAE/100 g. Compared with butylated hydroxytoluene (BHT) (control), all but one of the propolis samples exhibited higher DPPH activity. In addition, ABTS levels of propolis extracts were higher than those of BHT. These results unequivocally show that Turkish propolis has remarkable antioxidant qualities, which makes it a viable option for addition to food and medicine products.

The use of liquid organic amendments (biols) is a common practice for farmers due to the multiple benefits in the management and production of their crops, including the control of pests and diseases. The present study analyzes the chemical composition of the pure compound C1 and fractions F2 and F3 of local biols produced in two provinces of Ecuador and their antifungal activity against Moniliophthora roreri (Cif & Par). This work incorporates the use of Gas Chromatography coupled to Mass Spectrometry (GC-MS), Nuclear Magnetic Resonance (NMR) and in vitro inhibition assays for sample analysis. C1 was identified as Mannitol. The percentage of inhibition against M. roreri in F2 and F3 was 44.37% and 8.34%, respectively; and, for C1, 28.63%. The values of the median lethal dose (LD50) obtained corroborate that the F2 fraction was the one with the highest controlling activity against the pathogen. The 1,2-benzenedicarboxylic acid diisooctyl ester compound was the main compound in F2 (30.88%) and the Pentadecanoic acid, 14-methyl-, methyl ester in F3. Finally, all compounds obtained from the biol fractions were identified and it was determined that the fermentative process was suitable for producing bioactive compounds of interest to inhibit the growth of Moniliophthora roreri.
