The cowpea beetle, Callosobruchus maculatus (F.), is one of the detrimental insect pests of legume seeds in field and storage conditions. In the current study, the seeds of five lentil cultivars, Perkouz, Sana, Sepehr, Bileh-Savar, and Gachsaran, were evaluated for their resistance to C. maculatus based on life-table parameters, oviposition preference, and digestive function. The biochemical and physical features of studied cultivars were also evaluated to comprehend their potential correlations with examined pest parameters. In the free-choice experiment, the quantity of eggs deposited on Perkouz was highest, while it was lowest on Bileh-Savar. Developmental times on Bileh-Savar, Gachsaran, and Sepehr were longer than on Perkouz. The beetles fed with Bileh-Savar showed lowest net reproductive rate, intrinsic rate of population increase and finite rate of increase. Fourth-instar larvae exhibited lowest proteolytic and highest amylolytic activity on Bileh-Savar. Among the characteristics of lentil seeds, hardness index, moisture content, as well as starch and protein levels notably affect the population parameters of C. maculatus. Given the results of this investigation, Bileh-Savar is the most resistant cultivar for feeding and population increase of C. maculatus and can be considered in management strategies of this pest.

The objective of this study was to examine the impact of hazelnut proteins with varying levels of oxidation (0, 45, 90, 135, 180, and 225 d of storage) on the stability of O/W emulsions. The results demonstrated that hazelnut proteins with varying degrees of oxidation exhibited distinct effects on the stability of O/W emulsions. Mild and moderate oxidation resulted in an increase in the absolute ζ-potential, surface hydrophobicity, endogenous fluorescence intensity, centrifugal stability, emulsification index, adsorbed protein content, and viscosity of the emulsions, it caused a decrease in particle size and turbidity, ultimately leading to an improvement in the physical stability of hazelnut protein emulsions. Electrophoresis results demonstrate that proteins with moderate oxidation exhibit increased flexibility, which contributes to the development of a more compact interfacial structure and improved stability of emulsions. The decrease in viscosity as the shear rate increases suggests that hazelnut protein emulsions are characteristic of shear-thinning systems. Additionally, frequency scans reveal that all emulsions display an improved elastic structure in both the mid-and high-frequency ranges. Oil oxidation is an unavoidable process that occurs over extended periods of storage. However, emulsions containing a moderate level of protein oxidation exhibit reduced levels of oil oxidation products in comparison to other emulsions. This characteristic contributes to the stabilization of oil-in-water (O/W) emulsions. In conclusion, hazelnut proteins that have undergone moderate oxidation exhibit beneficial effects on emulsion stability, interfacial properties, and lipid oxidation.

This research investigates the impact of ultraviolet-C (UV-C) radiation exposure (5, 10, and 20 min) on the quality and storability characteristics of pea (Pisum sativum L.) seeds, focusing on technological properties (moisture content, bulk density and thousand grains weight), color stability (L∗, a∗, b∗, chroma and hue angle), ash content, and mineral composition (calcium, potassium, magnesium, phosphorus, and zinc). Seeds were stored at three different temperatures (15 °C, 20 °C, and 25 °C) for periods ranging from 0 to 360 days, with assessments conducted at 90-day intervals. The results demonstrate that UV-C treatment plays a significant role in maintaining seed quality throughout storage. Seeds exposed to 20 min of UV-C radiation and stored at 15 °C retained the highest moisture content and showed the least color degradation, particularly in terms of lightness (L∗) and chroma values. In addition, UV-C exposure positively influenced the mineral composition, particularly calcium and potassium content, which showed increased levels under UV-C treatments. However, magnesium and zinc levels were more variable, with some reductions observed over extended storage durations. The optimal conditions for preserving seed quality were found to be 20 min of UV-C exposure combined with storage at 15 °C for up to 270 days. These findings suggest that UV-C radiation, combined with controlled storage conditions, can effectively enhance the long-term quality of pea seeds, offering a sustainable, non-chemical method for the agricultural industry.

Ethyl formate (EF) exhibited promising activity against pests of stored date fruits, showing its potential as an alternative fumigant to replace phosphine and methyl bromide (MB). However, the information related to sorption, desorption and residues in date fruits is lacking. Therefore, the present study explored the sorption and desorption of EF at application doses of 70 and 140 mg/L in dry dates (Ghazali) and semi-dry dates (Elwadi-I). Moreover, the study developed and validated a method to determine the actual residues of EF in both date varieties using cooled methanol for extraction and analyzed by gas chromatography-mass spectrometry in selected ion monitoring. The actual amounts of EF residues in both date varieties fumigated at 70 and 140 mg/L for 24 h were quantified. The initial doses applied decreased by 71.5 and 52.9% at 70 mg/L and by 72.5 and 48.0% at 140 mg/L for Ghazali and Elwadi-I, respectively, after 24 h of fumigation. There was a notable desorption of EF from both date varieties, with about 20.0% released from the initial doses applied after 24 h of resealing. Sorption rates of EF in Ghazali and Elwadi-I were 237.71 and 185.17 mg/kg at 70 mg/L and 482.6 and 336.75 mg/kg at 140 mg/L, respectively. The developed method achieved a high level of precision and selectivity, with an acceptable recovery between 80.22 and 92.35% and a relative standard deviation <20.0%. The limit of detection (LOD) and limit of quantitation (LOQ) were 0.01 and 0.1 mg/kg, respectively. The initial amounts of EF residues in Ghazali and Elwadi-I date fruits after 0 h (15 min) of aeration were 48.24 and 30.08 mg/kg following the fumigation at 70 mg/L and were 95.95 and 81.74 mg/kg when fumigated at 140 mg/L, respectively. However, EF residues were undetectable after 72 h of aeration. These findings are important for the implementation of EF as a stored date protectant agent.

Traditional pesticides are facing increasing limitations due to concerns about global food security. Essential oils (EOs), as natural plant-derived alternatives, have gained attention for their insecticidal and antimicrobial properties. This review highlights the key constituents of EOs, including terpenes, aldehydes, alcohols, ketones, and alkaloids, and evaluates their effectiveness against grain storage pests and microorganisms. We discuss various extraction methods, highlighting their advantages and disadvantages. EOs are shown to act through fumigation, contact, and behavioral disruption, although their precise mechanisms of action require further study. Their applications extend to pest eradication, mold prevention, and weed control, enhancing the effectiveness of pesticides. The role of microencapsulation and nanotechnology in stabilizing EOs for broader use in grain preservation is also explored, emphasizing their potential to enhance stored grain safety. Balancing the discussion on essential oils' utility, this review emphasizes the necessity for continuous research and innovation in sustainable pest management strategies.

The saw-toothed grain beetle, Oryzaephilus surinamensis (L.) (Coleoptera: Silvanidae), is a secondary pest of stored products, previous studies have focused on grains and ignored their growth characteristics in packaged commodities. This study aimed to investigate the developmental and reproductive biology of O.surinamensis at 20–36 °C and 65%–85% relative humidity (RH) reared on dried noodles. The optimum temperature and humidity of O. surinamensis reared on dried noodles were 28 °C/85% RH, the index of population control was 0.24, the generation period was 49.86d, and the generation survival rate was 40%, the highest fecundity was 7.83 eggs. The temperature was more affected than relative humidity on the generation period, fecundity, and survival rate of O. surinamensis. The development of O. surinamensis was all completed in the range of 28–36 °C except 20 °C; the larval and pupal stages were more affected than the egg stage at 65%∼85% RH. Under the experimental conditions of temperature and humidity, the intrinsic rate of increase, and doubling time of the population were negative, and the population trend index was less than 1; the reproductive parameters of O. surinamensis decreased slightly as temperature (28–36 °C) increased or humidity decreased. Simulating different temperature and humidity conditions in dried noodles packaging, the O. surinamensis did not complete the generation development. The survival rate of O. surinamensis of each developmental stage and fecundity was highest at 28 °C/60% RH, followed by 36 °C/60% RH. The results showed that the ambient temperature below 20 °C and RH below 65% were beneficial to the prevention of O. surinamensis and its prevention in dried noodles is focused on the invasion of adults and eggs.

Anisopteromalus calandrae (Howard) (Hymenoptera: Pteromalidae) is recognized as a highly efficient biological control agent for several stored-product pests, targeting the late-instar larvae or pupae of various beetle species. Host plant metabolites may significantly affect species at the third trophic level. The life history traits of A. calandrae parasitizing Callosobruchus maculatus, which were reared on seeds from six legume species (broad bean, cowpea, lentil, green gram, chickpea, and soybean), were evaluated under controlled conditions of 27 ± 2 °C, 60 ± 5 % relative humidity, and a photoperiod of 10:14 (L:D) h. The longest development duration was recorded for soybean (28.56 days), while the shortest was noted for cowpea (12.41 days) and green gram (13.24 days). The parasitoid had the maximum female adult longevity (19.80 days) and fecundity (86.78 eggs) when reared on cowpea, whereas it demonstrated the lowest longevity (5.08 days) and fecundity (13.51 eggs) on soybean. The elevated values of net reproductive rate (R₀), intrinsic rate (r), and finite rate (λ) of A. calandrae were documented for the cohort raised on cowpea, while diminished values were seen on soybean. The life cycle parameters of A. calandrae were associated with the biochemical properties of the examined legume species. The energy stores of fourth instar C. maculatus larvae reared on various legume grains influenced the parasitoid's life history features. The potential correlation between the host plant metabolites and fourth instar larvae's energy reserves of C. maculatus with the life history traits of A. calandrae is explored. The findings could have implications for C. maculatus biological control.

The elevated values of net reproductive rate (<em>R</em><sub><em>0</em></sub>), intrinsic rate (<em>r</em>), and finite rate (<em>λ</em>) of <em>A. calandrae</em> were documented for the cohort raised on cowpea, while diminished values were seen on soybean. The life cycle parameters of <em>A. calandrae</em> were associated with the biochemical properties of the examined legume species. The energy stores of fourth instar <em>C. maculatus</em> larvae reared on various legume grains influenced the parasitoid's life history features. The potential correlation between the host plant metabolites and fourth instar larvae's energy reserves of <em>C. maculatus</em> with the life history traits of <em>A. calandrae</em> is explored. The findings could have implications for <em>C. maculatus</em> biological control.</div></div>","PeriodicalId":17019,"journal":{"name":"Journal of Stored Products Research","volume":"111 ","pages":"Article 102539"},"PeriodicalIF":2.7,"publicationDate":"2025-01-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143105055","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}

Sorghum, a crucial cereal crop for smallholder farmers in Ethiopia, serves as an essential source of food, income, and nutrition. The aim of this study was to evaluate the effects of five grain storage technologies: Purdue Improved Crop Storage (PICS) bags, ZeroFly bags, polypropylene bags, filter-cake-treated polypropylene bags, and underground pits on the physicochemical properties of sorghum grains and the sensory quality of injera prepared from stored grain. Using proximate composition analysis as per the Association of Official Analytical Chemists (AACC) standards, the results showed that after six months of storage, PICS bags preserved the highest germination energy (87.83%), whereas underground pits had the lowest (39.79%). PICS bags were the only technology maintaining germination viability above 85%. Moisture content increased across all storage technologies, with the most significant rise observed in underground pits (11.42%–17.48%). Nutrient losses, including reductions in protein, fiber, ash, and fat, were more pronounced in grains stored in filter-cake-treated bags, ZeroFly bags, polypropylene bags, and underground pits. However, minimum loss was recorded in the PICS bag. Sensory analysis demonstrated that injera made from sorghum stored in PICS bags received the highest preference scores. The findings highlight that PICS bags effectively preserve the physical, nutritional, and sensory quality of sorghum grains while mitigating storage losses. Consequently, PICS bags are recommended as a sustainable and eco-friendly solution for improving postharvest grain management in diverse agro-ecological settings in Tigray, Ethiopia.

Diatomaceous earth (DE), which possesses low mammalian toxicity and stability on grain, has promising potential in controlling stored grain pests. However, only a few published studies focus on the effectiveness during the long term storage. The current study assessed the long-term efficacy of DE, SilicoSec® on Sitophilus granarius, Rhyzopertha dominica, and Tribolium confusum using infestation with two adults per kg of wheat. The population density of each pest was monitored throughout one year in 50 kg of stored wheat treated with three doses of SilicoSec® (500, 1000, and 2000 mg/kg grain) in drums under laboratory condition. The number of adults (dead or alive) for S. granarius, R. dominica, and T. confusum was 8.00 ± 1.73, 2.00 ± 0.58 and 1.00 ± 0.58, respectively, at 2000 mg/kg dose of DE by 12 months of storage. The suppression rate was 95.2, 99.4, and 97.9% for S. granarius, R. dominica, and T. confusum, respectively, at 1000 mg/kg DE after 12 months of storage.

This study showed that wheat treated with SilicoSec® at 1000 mg/kg could be satisfactorily protected against major stored grain pests for a year. SilicoSec® has great residual efficacy for a year, which is generally not achievable with residual grain protectants.

The evaluation of diatomaceous earths (DEs) against a wide range of major stored-product insect pests highlights their possible importance in integrated pest management protocols, as an environmentally friendly alternative to conventional insecticides. This study was conducted to evaluate the insecticidal efficacy of two DEs from Serbia (DE S-1 and DE S-2, mined in the Kolubara region) and one commercial formulation (Protect-It®) applied at rates of 0.5, 1.0 and 1.5 g/kg, as maize protectants against the infestation of Plodia interpunctella. The total number of P. interpunctella adults that survived the treatment with DEs was recorded and the life history traits (mean developmental duration (MDD), sex ratio, adult longevity and fecundity) were investigated. Although Protect-It® proved 100% effective in protecting maize from P. interpunctella infestation in all three applied rates, both DEs from Serbia also showed significant efficacy. The results indicate that DE S-1 and DE S-2 could effectively suppress P. interpunctella infestation on maize, based on significantly low number of emerged adults, prolonged MDD and shorter adult longevity.

Fecundity was lower in the treatments with DE since only one pair of moths successfully mated and laid 41 eggs. No losses in maize weight were registered in treatment with Protect-It®. In DE S-1 and S-2 treatments, maize weight losses were significantly lower in comparison to the negative control. Diatomaceous earth S-1 applied at a rate of 1.5 g/kg and DE S-2 applied at rates 1.0 and 1.5 g/kg significantly influenced mean developmental duration and longevity of P. interpunctella adults and showed excellent insecticidal potential in this moth control and suppression on maize. The results of this study provide the necessary information about the possibility of preventive application of Serbian DEs, against P. interpunctella infestation.
