“…Infections by A. flavus mainly on grain damaged by ECB were visible at harvest. The importance of the ECB and other insects in the aetiology of aspergillosis of maize ear was confirmed by other literature data (Lillehoj et al, 1976;McMillian et al, 1985;Windham et al, 1999;Abbas et al, 2006). The correlation coefficient between precipitation factors for 2010 and 2012 indicates that environmental conditions or arid climate during the growing season of maize were similar.…”

“…Very high temperatures and extreme drought were recorded in the period from maize anthesis to the late dough stage in 2012, which resulted in a very low precipitation factor (0.27 to 1.45) or arid conditions. Similar environmental conditions that favoured proliferation of A. flavus had been described in Italy (Moretti et al, 2004), Kenya (Muthomi et al, 2012), the USA (Abbas et al, 2006) and other countries around the world. Stress conditions that reduce yield may play a role in predisposing maize infection by A. flavus or may increase aflatoxins production once infection has occurred (Jones et al, 1981).…”

SUMMARYThe frequency and incidence of A. flavus and A. niger on barley, maize, soybean, sunflower and wheat grain, the abundance of European corn borer (Ostrinia nubilalis) moths and their interaction depending on weather conditions in the 2008-2012 period were studied. Under the agroecological conditions of Serbia, the species A. niger is more frequent than A. flavus, and concerning the crop species, its frequency is highest in kernels of sunflower, than soybean, maize, barley and wheat. A. flavus was extremely dominant on all plant species in 2012 regarding its frequency: 100% on soybean, 95.3% on maize, 65.2% on barley, 57.1% on sunflower and 45.8% on wheat. Furthermore, the incidence of A. flavus was higher in 2012 than in previous years. The uncommonly high frequency and incidence of A. flavus infestation of maize grain in 2012 were caused by extremely stressful agrometeorological conditions, high temperatures and drought over the period from flowering to waxy maturity of maize. The precipitation factor (Pf = precipitation sum / average monthly temperature) showed that 2012 was extremely arid in June (Pf = 0.57), July (Pf = 1.45), August (Pf = 0.15) and September (Pf = 1.42). European corn borer (ECB) was a second factor causing intensive occurrence of A. flavus on maize grain in 2012. The maximum flight of ECB moths was recorded as early as in July (5,149) and, as a result of this, high damage and numerous injuries were detected at harvest. Those injuries were covered by visible olive-green powdery colonies typical of A. flavus. In the chronology of A. flavus occurrence, these are the first data on its very high frequency and incidence under the agroecological conditions of Serbia. As intensive infections with A. flavus were rare in the past 50 years, the level of aflatoxins in maize grain was low.

“…Therefore, depending on storage conditions, the corn kernels lose mass, volume and strength and also experience nutritional degradation, discoloration, development of unpleasant odors, heat and chemical changes, and growth of fungi with toxigenic potential for mycotoxin contamination (Bento et al, 2012 Because of the economic and dietary importance of corn, fungal contamination is currently one of the primary problems in the storage of kernel corn (Moreno et al, 2009). As a substrate rich in starch, corn is one of the cereals most likely to suffer contamination by fungi, primarily Aspergillus and Fusarium (Abbas, Cartwright, Xie, & Shier, 2005;Mohale, Medina, Rodriguez, Sulyok, & Magan, 2013). These fungi are known for the mycotoxigenic potential (Rocha et al, 2009).…”

ABSTRACT. The aim of this study was to assess alternatives for viable corn storage for small rural properties in two annual storage experiments. A 4×5 factorial design was used with four types of storage (conventional bags, hermetic bags, metal silos and corncobs) and five periods of storage (0, 3, 6, 9 and 12 months). We used corn hybrids 2B688RR and 30K73Hx cultivated in winter 2012 and summer 2012/2013 in the city of Dois Vizinhos, Paraná, Brazil. The moisture contents, counts of Aspergillus sp. and Fusarium sp., and the occurrence of aflatoxins (B 1 , B 2 , G 1 and G 2 ) were assessed. The kernels stored in hermetic bags had lower moisture contents. Aspergillus sp. and Fusarium sp. were observed in 20.37 and 86.11% of winter storage samples, respectively, and in 83.3 and 91.6% of summer storage samples, respectively. The storage system and time of storage had no influence on the occurrence of Aspergillus sp. and aflatoxins in the winter crop samples. The corncobs from the summer crop samples had the lowest counts of Aspergillus sp. and did not have aflatoxins. We detected aflatoxins at concentrations of 2.8-14.5 and 3-197.5 μg kg -1 in the winter and summer crop samples, respectively.

“…LC-MS/MS appears to be most promising as a highly specific, broadly applicable detection method that provides both qualitative and quantitative data. Considering the possible contamination of foodstuffs by several mycotoxin producing fungal species and the production of different types of mycotoxins by one mould, a trend is to develop methods suitable for the determination of several mycotoxins in a single run (Sewram et al 1999;Monti et al 2000;Rundberget and Wilkins 2002;Royer et al 2004;Berthiller et al 2005;Cavalière et al 2005;Kokkonen et al 2005;Sorensen and Elbaek 2005;Abbas et al 2006;Delmulle et al 2006;Monbaliu et al;Sulyok et al 2006;Spanjer et al 2008). Currently published protocols, however, have been developed and optimized for different foods and feeds.…”
