Special Issue Information

Dear Colleagues,

Agricultural products play significant roles in our daily lives. However, the quality and value of these products can be greatly impacted by the presence of harmful biological organisms such as pests, diseases, and invasive species during the postharvest stage. To address this, postharvest biosecurity measures are implemented during the handling, storage, and exportation of these products in order to prevent and reduce the effects of biological threats. This may involve activities such as monitoring for the presence of harmful organisms, implementing quarantine procedures, and developing effective treatments for managing pests and diseases. Therefore, postharvest biosecurity is essential for protecting agricultural products, communities, and the environment from potential harm.

We invite scholars in this field to submit articles related to postharvest security in agriculture, including original research, short communications, and reviews, for inclusion in this Special Issue. This publication will cover all aspects of postharvest biosecurity research throughout the supply chain, including storage technologies, treatments, underlying mechanisms, quality evaluation, packaging, handling, and distribution. We are particularly keen to promote environmentally friendly “green” technologies, such as low-toxicity chemical and non-chemical treatments.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Agriculture is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Cold treatment has been extensively employed for the phytosanitary control of fruit flies for citrus cultivation worldwide. Trials with artificial infestation methods on navel and Valencia oranges at 3 °C and 2 °C against the oriental fruit fly (Bactrocera dorsalis) were conducted, following standard bioassay protocols and large-scale testing. The results showed that the third instar larval stage was the most tolerant stage in both cultivars. The maximum estimated cold treatment time at 3 °C required to produce 99.9968% mortality (LT99.9968) with a 95% confidence level was 16.6 days and 16.2 days for the navel orange and Valencia orange, respectively. Meanwhile, the estimated cold treatment time at 2 °C was 14.8 days for both navel and Valencia oranges, with a 95% confidence level. Furthermore, it was also observed that no survivors came from a total of 104,420 estimated (51,396 for the navel cultivar and 53,024 for the Valencia cultivar) third instar larvae in orange fruits after being subjected to a cold treatment of 3 °C for 17 days. Meanwhile, there were also no survivors from a total of 100,556 (50,740 for the navel cultivar and 49,816 for the Valencia cultivar) third instar larvae in orange fruits after being subjected to a cold treatment of 2 °C for 15 days. The treatments at 3 °C for 17 days and 2 °C for 15 days on oranges, including navel and Valencia, against the oriental fruit fly, surpassed the required mortality assurance of 99.9968% at a 95% confidence level and also met the probit-9 mortality standard. Overall, the application of these results will provide more flexibility for the citrus industry to satisfy quarantine treatment requirements. Full article

Ethyl formate (EF), a naturally occurring fumigant, has attracted widespread attention owing to its low toxicity in mammals. Here, Direct Immersion Solid-Phase Microextraction (DI-SPME) was employed for sample preparation in mass spectrometry-based untargeted metabolomics to evaluate the effects on Tribolium castaneum (Herbst) strains with different levels of PH3 resistance (sensitive, TC-S; moderately resistant, TC-M; strongly resistant, TC-SR) when exposed to a sub-lethal concentration (LC30) of EF. The bioassay indicated that T. castaneum strains with varying PH3 resistance levels did not confer cross-resistance to EF. A metabolomic analysis revealed that exposure to sublethal doses of EF significantly altered 23 metabolites in T. castaneum, including 2 that are unique to the species which remained unaffected by external conditions, while 11 compounds showed a strong response. A pathway topology analysis indicated that EF caused changes to several metabolic pathways, mainly involving fatty acids and their related metabolic pathways. This study showed that EF can induce highly similar metabolic responses in insects across varying levels of PH3 resistance, suggesting that the mechanisms driving the toxicity of EF and PH3 are distinct. These insights significantly extend our knowledge of the toxic mechanisms of EF and provide direct evidence for the efficacy of EF treatment for managing PH3 resistance in insects. Full article
