TL;DR: In this paper, the authors investigated the effectiveness of hermetic maize storage, particularly where the Larger Grain Borer (LGB), Prostephanus truncatus occurs, and showed that hermetic storage can be an effective pesticide-free alternative to synthetic pesticides in reducing grain storage losses under smallholder farming conditions.

TL;DR: The findings of the present work show that some commodities are more prone to spread T. granarium than others, a fact which should be seriously taken into account in international trade of grains and related amylaceous products.

TL;DR: The results indicate that repeatedly breaking the hermetic seal of the PICS bags will increase fungal growth and the risk of aflatoxin contamination, especially in maize stored at high moisture content, and further demonstrates that maize should be properly dried prior to storage in PICSbags.

TL;DR: In this paper, the effect of storing maize in triple layer hermetic (PICS) bags on aflatoxin contamination was evaluated in small-scale farmers' grain stores in an endemic region.

TL;DR: Fumigation in unsealed storages, combined with a high frequency of weak resistance, were found to be the main criteria that led to the development of strong resistance in Sitophilus oryzae.

TL;DR: None of the insecticides were able to totally control T. granarium larvae, illustrating the difficulties in controlling this species, with dose rates that are usually effective for other major stored product beetle species.

TL;DR: In this paper, a pilot-scale, 27.12MHz, 6kW RF system was used to study the RF heating uniformity and validate the developed RF treatment protocols for disinfesting rough, brown, and milled rice.

TL;DR: In this paper, a pilot-scale, 27.12MHz, 6-kW RF system was used to simulate the continuous industrial processing and finally estimate the heating efficiency and throughput for controlling adult rice weevils, Sitophilus oryzae (L.), in milled, brown, and rough rice.

TL;DR: In this article, the authors explored the possibility of using radio frequency (RF) heating as an effective treatment to eliminate the mold contamination and reduce the damage to corn quality, and developed a treatment protocol for a corn sample with the MC of 15.0% w.b.

TL;DR: The development of effective protocols will be facilitated by studies that clearly and completely describe experimental and statistical methods, consider factors (life-stage, acclimation, diapause) that increase tolerance to extreme temperatures, and assess the mortality at various temperatures to develop mathematical models.

TL;DR: Higher moisture content of grain seeds would benefit fungi inhibition for hot air-assisted RF treatment, and with proper control of treatment conditions, hotAir- assisted RF heating has the potential to inhibit fungi and maintain physiological and biochemical quality of grain Seeds.

TL;DR: Essential oils of citrus peels (industrial waste) could be widely used for C. maculatus control and could gain economic value if used on a large scale to produce essential oils.

TL;DR: Hermetic storage of common beans is an effective tool in the control of A. obtectus; there was a significant increase in infestation in the grains in non-hermetic storage (control); the quality of the beans correlated with infestation; it was not altered in the hermetic storage systems and decreased in thecontrol sample.

TL;DR: In this article, three commercially available zeolite formulations were evaluated against adults of Sitophilus oryzae, Tribolium confusum and Oryzaephilus surinamensis in wheat.

TL;DR: Overall, this study adds knowledge to the mating behavior of S. oryzae, highlighting the impact of the geographical origin and the rearing commodity on male mating success and laterality.

TL;DR: In this paper, the changes in rice grains structure and digestion behaviors were investigated following storage at 4°C and 37°C, respectively, and the analysis of the amount of cell wall remnants showed that rice stored at 37°C caused a significant increase in the cell wall residuals along the storage at 37''C, which might suggest that the cellwall structure of the rice grains became more lignified because of the ageing.

TL;DR: The effect of CA was lethal on C. maculatus, did not affect chickpea quality, and it favored chick pea vigor.

TL;DR: The NIR hyperspectral system can differentiate between different fungal infection stages and different levels of Ochratoxin A contamination in stored wheat using a Near-Infrared Hyperspectral Imaging system.

TL;DR: Results show that methoprene used as a grain protectant will give residual control of stored product beetles for 24 months, but complete control of S. cerealella may require inclusion of a contact insecticide.

TL;DR: The findings suggest that Allyl isothiocyanate is a potential tool that may be integrated into the control strategies of maize weevils where resistance to phosphine and other conventional insecticides is a problem.

TL;DR: It is shown that various wheat cultivars have significant effects on life history, demographical parameters and nutritional indices of T. granarium which could prove useful in the development of IPM programs for this pest.

TL;DR: Residual toxicity of the pyrethroids deltamethrin and β-cyfluthrin, applied on a concrete surface substrate for control of adults and larvae of both species, was evaluated to provide initial baseline susceptibility data for dermestids.

TL;DR: In this article, the authors evaluated the ability of two mycotoxigenic species Aspergillus flavus and A. niger, isolated from barley, to produce aflatoxin B1 (AFB1) and ochratoxin A (OTA), respectively, as affected by nutritional and environmental factors.

TL;DR: Two populations of Sitophilus zeamais populations that were subjected to successive cycles of selection with O 3 did not acquire resistance to O 3, and the pattern of locomotion and the rate of respiration did not change following the selection cycles with O3.

TL;DR: The packaging types evaluated in this study can potentially protect food products stored in these packages from infestations of T. castaneum and T. variable and hatchability of eggs laid by both species was not significantly different among the treatment combinations.

TL;DR: H. sabdariffa grain was stored infested in woven polypropylene bags typically used by farmers, and the Spermophagus population increased 33-fold over that initially present, while grain held for the same length of time in PICS bags experienced no increase in the numbers of holes.

TL;DR: In this article, the effects of temperature with water activity (aw) and CO2 with aw on the growth and aflatoxin production by Aspergillus flavus Link on paddy were evaluated using full factorial design.

TL;DR: In this paper, the authors used non-linear regression to predict the mold counts (log 10 ǫCFU/g) for varying conditions (correlations = 0.65-0.76).

TL;DR: Assessment of the feasibility of the NIR hyperspectral imaging system to identify fungal infections in pulses showed promising results as it gave 85–90% accuracy for the six-way model and 96–100% Accuracy for the two-way models.

TL;DR: In this paper, the efficacy of gaseous ozone for the degradation of aflatoxin B 1 (AFB 1 ) and inactivation of indigenous microflora in poultry feed was evaluated.
