“…Stored grain is a man-made ecosystem undergoing persistent interactions between several abiotic and biotic factors, and which more or less is aff ected by the surrounding bioclimatic environment. As noticed before, grain storage itself can be heavily aff ected by climate change (Moses et al, 2015), therefore safe food grain storages by themselves are considered as a measure to adapt to the changing global climates (UNEP, 2010). Global climate patterns have been shown to change notably and are predicted to continue to change in the future.…”

In this study an attempt is made to highlight important variables shaping the current bioclimatic niche of a number of mite species associated with the infestation of stored products by employing a species distribution modeling (SDM) approach. Using the ENVIREM dataset of bioclimatic variables, performance of the most robust models was mostly influenced by: 1) indices based on potential evapotranspiration, which characterize ambient energy and are mostly correlated with temperature variables, moisture regimes, and 2) strong fluctuations in temperature reflecting the severity of climate and/or extreme weather events. Although the considered mite species occupy man-made ecosystems, they remain more or less affected by the surrounding bioclimatic environment and therefore could be subjected to contemporary climate change. In this respect investigations are needed to see how this will affect future management targets concerning the safety of food storages.

“…However, global climate patterns have shown to change notably (IPCC, 2018) and grain storage itself can be heavily aff ected by climate change. Th e conclusion that seasonal variations would have an eff ect on mite population (Sinha, 1968) indicates that climate change would also have similar eff ects (Moses et al, 2015).…”

“…It was also reported that the survival temperature ranges from 5 to 41 °C for stored product pests. Several biotic and abiotic factors add to these variations, which include wind, rain, solar radiations, atmospheric temperature and humidity, storage structure, moisture content, and contamination (Moses, Jayas, & Alagusundaram, 2015; Sinha, 1995). Wind can help in the movement of pests from one location to nearby storage facilities and also contribute to moisture variations.…”

“…In a review by Moses et al. (2015), the implications of climatic changes in the physical quality of food grains, infestations, microbial, and fungal growth were assessed. Further studies have to be performed with a multifaceted approach to the interactions of different climatic parameters and the subsequent changes in variables such as temperature and humidity, which has a direct impact on stored product pest infestations.…”

Management of stored product insects is a major concern and widely researched topic in the food and grain processing and storage industry. In the scenario of estimated utilization of produces exceeding the production, postharvest losses should be properly controlled to feed the growing population. The prevailing disinfestation techniques are forced to meet regulatory standards and market demands. The resistance developed by insects, environmental concerns, and occupational hazards lead to the vanishing of many chemicals used in insect and pest management programs. Some of the major disinfestation techniques such as the use of chemical fumigants, ozone, irradiation, dielectric heating, extreme temperature treatments, and bio rational approaches are discussed, particularly on the storage of cereal grains and its products, as they contribute to a significant proportion of food consumed worldwide. Newer techniques such as nonthermal plasma and metabolic stress disinfestation and decontamination for stored pest control are developed and evaluated in different parts of the world. The knowledge about the mode of action of these disinfestation techniques is important to avoid the cross-resistance and multiple resistance developed by insects with frequently used techniques. Various alternatives to conventional fumigants are discussed in this review as there is a growing demand for toxic-free, environment-friendly, and, at the same time, efficient techniques.

“…Stored grain ecosystems can be heavily affected by changing global climates. [38,39] Air temperature is a fundamental biophysical variable that influences almost all biotic processes, as well as many abiotic processes globally. [40] The primary objective of this paper was to identify a simpler method to estimate grain pile temperature from air temperature, aiming to provide a window for warehouse keepers who try to grasp the change of grain temperature in real time.…”

Food security is an influential factor for the development and future of humanity. Stored grain temperature is a key physical variable for grain quality control and management in stored-grain ecosystem. In this study, a prediction model using Fourier series based on least-squares method is introduced to describe the average temperature movement of grain pile and the daily air temperature, naming hysteresis cycle model (HCM). Then the HCM based on the Fourier analysis is proposed that incorporating with the least-squares method, the Fourier series model is applied to forecast the grain pile temperature from the daily air temperature. The HCM is built by finding relationship called conversion coefficients between the air and grain pile temperature that is constructed on the basis of Fourier analysis, and the optimal order of the model is determined by Akaike information criteria. Our method can reflect the time lag of the grain pile temperature changes with the change of air temperature and requires only a single variable (i.e. air temperature). Experiments including model fitting, temperature prediction, and results comparison for a period of 425 days from a real-world granary, yield satisfied results agreeing well with actual observation values. As a result of model validation, the proposed method has the root mean square error (RMSE) values ranging from 1.6°C to 2.3°C with average RMSE of 1.9°C. In other words, the proposed model can predict grain pile temperature with a high accuracy once an acceptable relationship between air temperature and grain pile temperature has been constructed from previously temperature data. Result analysis indicates effectiveness and workability of the proposed model for stored grain temperature prediction.
