However, their ability to disperse within grain piles and structures (warehouses and processing facilities) has not been well assessed. This study aimed to evaluate two predatory mites, <em>Blattisocius tarsalis</em> and <em>Cheyletus malaccensis</em>, as biological control agents by examining their dispersal abilities in piles of rice grains and storage facilities. The mites were evaluated for their capacity to navigate vertically through polyvinyl chloride (PVC) tubes filled with paddy rice at depths of 40 and 100 cm to determine if they could reach the eggs of various lepidopteran pests at the bottom. Additionally, their dispersal ability over varying time intervals and their preferences concerning light intensity were assessed in 2-m-long channels coated with rice flour residues. An integrated assessment of their vertical and horizontal dispersal capacities, along with the influence of light, was conducted in a controlled pilot storage room (4 × 3 × 3 m). <em>Blattisocius tarsalis</em> demonstrated impressive dispersal capabilities, reaching pest eggs at vertical depths of 40 and 100 cm through rice and dispersing 2 m horizontally in just 4 h. This proficiency extended to pilot storage room conditions, where it successfully navigated all distances, both horizontally and vertically, showing a preference for navigating away from the light. <em>Cheyletus malaccensis</em> proved to be an effective predator at close range to pest eggs but demonstrated limited dispersal capabilities in complex setups. This study underlines the suitability of <em>B. tarsalis</em> as a biological control agent capable of dispersing in various environments. Conversely, the utility of <em>C. malaccensis</em> may be more specialised and effective within a narrow movement range. These findings highlight the importance of understanding mite dispersal behaviours for optimising pest management strategies and contributing to the more sustainable and effective storage of rice grains.</div></div>","PeriodicalId":17019,"journal":{"name":"Journal of Stored Products Research","volume":null,"pages":null},"PeriodicalIF":2.7,"publicationDate":"2024-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142572826","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this research, the effects of various grain species, including barley, maize, millet, rice, sorghum, and wheat, were assessed on biological properties and life history variables of <em>S. oryzae</em> under laboratory conditions. Data were analyzed based on the age-stage, two-sex life table method. Furthermore, various physicochemical properties of cereal grains, including protein content, starch content, humidity content, and seed hardness, were investigated to explore their correlation with the studied parameters of <em>S. oryzae</em>. The longest development time was observed on millet and sorghum hosts, while the shortest was on maize seed. The beetles reared on rice and millet species showed the maximum fecundity, whereas those reared on sorghum and millet grains showed the lowest. Maize grain had the highest intrinsic rate of increase (<em>r</em>), whereas millet and sorghum grains had the lowest. According to the correlation analysis, overall, seed protein content was negatively correlated with insect fecundity, <em>R</em>₀ and <em>r</em>, but positively correlated with development time. Furthermore, starch content was positively correlated with insect fecundity, <em>R</em>₀ and <em>r</em>, and negatively correlated with development time. The cluster results demonstrated that whereas sorghum and millet were comparatively resistant hosts for the growth of <em>S. oryzae</em>, maize and rice were relatively susceptible seeds. This information can be helpful in the development or improvement of integrated pest management (IPM) strategies against rice weevil. The findings of this research will also be helpful in introducing unsuitable hosts for the development of transgenic grains resistant to <em>S. oryzae</em>. The pest-resistant cereal grains identified in this study can potentially be utilized in combination with other pest control strategies for sustainable management of <em>S. oryzae</em>, which may help reduce the excessive use of chemical insecticides.</div></div>","PeriodicalId":17019,"journal":{"name":"Journal of Stored Products Research","volume":null,"pages":null},"PeriodicalIF":2.7,"publicationDate":"2024-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142572825","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 extensive usage of chemical insecticides for insect control has caused enormous harm to the worldwide ecology. Hence, it is essential to look for more environmentally sustainable solutions. Several essential oils (EOs) and bioactive chemicals have been adopted as natural insecticides due to their considerable insecticidal activity, diversified mechanism of action, and nontoxicity to other organisms. Meanwhile, despite their potential features, EOs have certain disadvantages, including being extremely volatile, less water-soluble, more rapidly degradable and the cost of production in some cases. Encapsulating EOs as nanoemulsions into polymers has recently been recognized as a potential technique for increasing their stability, selective release, and usefulness in various domains. These EOs and nanoemulsions displayed insect-deterrent behaviour by acting as fumigants, contact repellents, antifeedants, egg development deterrents, and larval agents, in addition to inhibiting chemical messengers such as acetylcholinesterase (AChE) and octopamine and transforming enzyme performance. This review article summarizes recent trends and innovations to define polymeric nano-formulated EOs as environment-friendly substitutes for harmful conventional insecticides. It also provides opportunities for more secure and profitable methods of controlling agricultural insects.
