Although essential oils demonstrate promising activity, their utilization faces hurdles related to standardization. In this study, contact/fumigation properties of three molecules (methyl salicylate, limonene and thymol) known for their activity against stored product beetles, were tested in laboratory bioassays toward young and old larval stages of <em>Trogoderma granarium</em>. The experiment revealed significant differences in their effects based on larval age and chemical concentration. Methyl salicylate exhibited concentration-dependent effects on both young and old larvae, with higher concentrations leading to accelerated mortality rates. For instance, young larvae exposed to 10 mg displayed an LT50 of 33.75 h, while old larvae showed an LT50 of 39.07 h. Similarly, at a concentration of 5 mg, young and old larvae exhibited LT50 values of 72.79 and 79.68 h, respectively, after treatment. Limonene also exhibited concentration-dependent effects, although with lower potency compared to methyl salicylate. Thymol showed efficacy only against young larvae of <em>T. granarium</em>. Statistical analyses confirmed the significant impact of each chemical on larval survival time, with tested chemicals displaying significant concentration-dependent variations in mortality rates. These findings suggest the potential of methyl salicylate, and to a lesser extent limonene and thymol, as effective biocidal agents against <em>T. granarium</em> larvae.</p></div>","PeriodicalId":17019,"journal":{"name":"Journal of Stored Products Research","volume":null,"pages":null},"PeriodicalIF":2.7,"publicationDate":"2024-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141303766","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}

In particular, it tackled the thermal development modelling of this pest in a two-fold approach, given the current lack of information on the cryptic post embryonic development in terms of degree-days. Baseline data were collected by laboratory rearing that considered the insect reproductive diapause and proposed first insights for developing a protocol to rear this pest under controlled conditions.

The effect of temperature on the sex ratio of the next generation was also investigated.

Despite government efforts to increase maize production, huge postharvest losses are recorded, with increased hunger and food cost. Granaries constitute for many farmers the safest and most economical way to store their crops. In this study, we investigated the diversity, distribution and structural characteristics of granaries used for maize storage and conservation across Benin agroecological zones as well as the factors that determine postharvest losses of maize in the Republic of Benin. In total, 345 households were surveyed in five agroecological zones (AEZ) based on a structured interview. Qualitative and quantitative data including sociodemographic parameters, granary characteristics, maize grain conservation forms, and postharvest losses associated with different granaries were recorded. Descriptive statistics were used to characterize both granary types and conservation methods across AEZ. To establish associations between farmers' conservation methods and granary types, Factorial Analysis of Correspondence (FAC) was performed. The factors influencing maize postharvest losses were investigated using a multiple linear regression analysis. Results showed six types of granaries classified into two main groups: Agoh, Avah, Akah, and Loumourè made of plant materials and Dibo and Bourarou made of clay. The granary type used was AEZ and socioethnic group dependent and was also function of the conservation method used by farmers. Granaries in southern AEZ were more prone to losses than those in the northern zone. The regression model showed that agroecological zone, education level, granary type, conservation method and maize storage form influenced the losses in maize production as perceived by farmers. This study highlights the need for extension agents and decision-makers to improve and adapt approaches used in postharvest loss management based on granaries structures characteristics and efficiency, local climate and accessibility of building materials within farmers' surroundings.</p></div>","PeriodicalId":17019,"journal":{"name":"Journal of Stored Products Research","volume":null,"pages":null},"PeriodicalIF":2.7,"publicationDate":"2024-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141195307","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}

No statistical differences were observed between samples stored under different atmospheres, while significant differences were highlighted as a result of the storage temperature, e.g. the alpha acids content at 4 °C was significantly higher (P = 0.002).
