Despite this recognition, certain species such as <em>Lavandula mairei</em> Humbert have received no attention. For this reason, our study offers a close insight into the chemical profile, insecticidal (i.e. fumigant and contact toxicity), repellent, and antifeedant effect of <em>Lavandula mairei</em> var. <em>antiatlantica</em> (Maire) Maire essential oil (LMEO) against <em>Sitophilus oryzae</em> (L.), a major stored product insect. Additionally, the major compound of LMEO, i.e. carvacrol, was also tested for the aforementioned bioactivities. In the fumigant bioassays LMEO and carvacrol showed LC₅₀ values of 69.5 and 69.3 μL/L of air, respectively, after 72 h while in the contact bioassays LC₅₀ values of 0.14 and 0.117 μL/insect, respectively, after 24 h. In terms of antifeedant effect, carvacrol and LMEO significantly influenced the Feeding Deterrent Index (FDI) recording 83.2 and 55.0%, respectively, at a concentration of 3.2%. Furthermore, a notable reduction of 5.5 and 2.1-fold in Relative Consumption Rate (RCR) was observed for carvacrol and LMEO, respectively, compared to the control. Regarding the repellent effect, carvacrol and LMEO exhibited percentages of repellency (PR) of 94 and 82%, respectively, at 0.312 μL/cm² after 24 h. In conclusion, our study underscores the significant insecticidal, feeding deterrent, and repellent effects of LMEO and its major compound against the rice weevil. Its cultivable potential and bioactivities confirmed through this study promote its use as sustainable pest control solution.</p></div>","PeriodicalId":17019,"journal":{"name":"Journal of Stored Products Research","volume":null,"pages":null},"PeriodicalIF":2.7,"publicationDate":"2024-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140843028","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, postharvest grain deterioration due to insect infestation is a significant issue. To address this and improve food availability, reducing storage losses is essential. The experiments were carried out in both indoor and outdoor settings, where the indoor experiment evaluated the effectiveness of different storage facilities (jute sack, PICS bag, fertilizer bag, AgroZ® bag, and polypropylene bag) over varying durations (0, 2, 4, 6, and 8 months) in three replications. In the outdoor experiment, traditional and modified <em>gombisa</em> constructed in an open field at the Jimma University Research Site (Eladale), along with different storage duration (initial loading, 2, 4, 6, and 8 months after storage), were evaluated in three replications. The data collected included grain damage percentage, weight loss, seed germination, and proximate analysis. Statistical analysis revealed significant differences in grain damage, weight loss, and seed germination of grains stored in different storage types. Jute sacks showed the most severe damage to grains and weight loss, while PICS and AgroZ® bags had the lowest values. The PICS and AgroZ® bags exhibited the highest seed germination, while the Jute bags had the lowest. In particular, traditional <em>gombisa</em> storage resulted in more significant grain damage, weight loss, and reduced germination than modified <em>gombisa</em>. As storage duration increased, grain damage and weight loss increased significantly in Jute sacks, Polyethylene bags, and traditional <em>gombisa</em>. Furthermore, the proximate analysis showed that storage periods and facilities significantly affected the characteristics of the quality of the maize grain. The moisture content, the crude protein, and the crude fat decreased with longer storage durations in all storage types, while the crude fiber and the ash content increased. The results confirmed the effectiveness of PICS, AgroZ® bags, and modified <em>gombisa</em> in reducing the qualitative and quantitative losses caused by the infestation of storage insect pests. These storage methods can be recommended to protect maize grain for eight months.</p></div>","PeriodicalId":17019,"journal":{"name":"Journal of Stored Products Research","volume":null,"pages":null},"PeriodicalIF":2.7,"publicationDate":"2024-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140824352","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A 5-point Likert scale and Kendall's coefficient of concordance was used to examine the perception about aflatoxin contaminations and constraints faced in managing aflatoxins in groundnut production, respectively. A multivariate probit model was further employed to analyze the factors influencing the adoption of aflatoxin management strategies. The results revealed that 92% of the farmers were aware of aflatoxin contaminations, however, only 20.7% of the farmers had received aflatoxins training. The results also showed that farmers are in agreement about aflatoxin contaminations in groundnut production. The most commonly adopted aflatoxin management strategies by farmers were timely harvesting, crop rotation, sorting, and storage in aerated and covered environment. Furthermore, the empirical results showed that education, credit access, membership in farmer based organizations, distance to farm, off-farm activity and location had a significant influence on farmers' adoption of all aflatoxin management strategies. Pest and disease incidence, and rainfall variability were identified as major constraints faced by smallholder groundnut farmers in Ghana. There is the need for periodic public sensitizations and technical capacity building of smallholder farmers to adopt aflatoxins management strategies which could improve groundnut productivity and ensure food security in Ghana.</p></div>","PeriodicalId":17019,"journal":{"name":"Journal of Stored Products Research","volume":null,"pages":null},"PeriodicalIF":2.7,"publicationDate":"2024-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140818592","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The bags were filled with 25 kg of maize, sealed, and stored over 12 months or less, depending on seed moisture content. Then, samples were taken out monthly to measure the moisture content, acid value, electric conductivity (EC), oil content, germination, bulk density, and the relative humidity, temperature, CO_2, and O₂ within the bags. Different mycotoxin strain contamination was measured as well. The results revealed that in the hermetic bags, the O₂ concentration decreased to only 7%; the moisture content in EHB was &lt;14% throughout the storage period, whereas it rose above 14% in the other bags. The EC, acidity, and bulk density were lower in EHB and SHB than in the other bags. The relative humidity was higher in the SAHB than in the EHB and SHB, while germination after 12 months was higher in SHB and EHB (&gt;50 %) than in SAHB (&lt;45%) and remained unaltered during the first few months of storage in EHB when compared with pre-storage seeds. The seeds from SAHB had lower Fumonisin and aflatoxin concentrations than seeds from the other bags. These results suggest that EHB is the best among the tested bags in preserving the quality of maize at different moisture contents. However, in the face of mycotoxin contamination, SAHB, despite suppressing mycotoxins, significantly reduced seed quality and so would not be suitable for maize storage.</p></div>","PeriodicalId":17019,"journal":{"name":"Journal of Stored Products Research","volume":null,"pages":null},"PeriodicalIF":2.7,"publicationDate":"2024-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140813178","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study also includes a simulated warehouse test to assess the efficacy of these substances as contact agents, fumigants, repellents, and antifeedants. All of these anti-insect activities were positively correlated with the concentrations of <em>E. ciliata</em> EO and carvone. Firstly, in the contact activity assay, <em>E. ciliata</em> EO and carvone completely inhibited the hatching of eggs and pupae of the <em>T. castaneum</em> at a concentration of 2.5 μL/cm². The LC₅₀ of <em>E. ciliata</em> EO and carvone were 7.62 and 4.33 μg/adult, respectively, against senior adults (5 weeks old). Secondly, in the fumigant activity assay, 60 mg/L of <em>E. ciliata</em> EO and carvone essentially completely inhibited pupae eclosion. On the other hand, the LD₅₀ of <em>E. ciliata</em> EO and carvone against senior adults (5 weeks old) were 8.72 and 5.02 mg/L, respectively. Thirdly, for <em>T. castaneum</em> adults, at the highest test concentration, the repellent rate of the <em>E. ciliata</em> EO was above 90%. Fourthly, the larvae and adults of the <em>T. castaneum</em> could reach complete antifeedant activity by <em>E. ciliata</em> EO and carvone at the highest test concentrations. Finally, 3000 ppm of carvone was sufficient to kill all the pests in the warehouse in the simulated warehouse test.

People are drawn to products that are bright red because they look fresh. Meanwhile during storage, strawberries lose their form and color, and their biochemical qualities, such as anthocyanins, flavonoids, phenols, and antioxidants, change as well. These natural substances in strawberries are important for keeping people healthy and meeting their food needs.
