“…Toteja et al (2006) collected 1,646 wheat grain samples from different geographical regions of India and found AFB1 in 43% of them ranging from <5 to 606 μg/kg. In another study, Ranjan et al (1992) found aflatoxin levels in 50 wheat samples out of 197 collected from various places in India. Sinha and Sinha (1991) collected 416 samples consisting of wheat, gram and maize flours from various places in Bihar, India, and recorded 162 positive for aflatoxins.…”

Thirty samples consisting of wheat (15) and barley (15) were collected from different markets in Penang, Malaysia, originating from India and Thailand, respectively. All samples were analyzed for occurrence of Aspergillus spp. and aflatoxin B1 (AFB1). Aspergillus flavus was dominant in all samples followed by A. niger. AFB1 could be detected in three wheat samples ranging from 0.42 to 1.89 μg/kg and one barley sample had 0.58 μg/kg of AFB1. The AFB1 levels in all the samples were below the Malaysian regulatory limits (<35 μg/kg). The frequency and quantity of AFB1 levels in this study were very low in wheat and barley samples compared to other agricultural commodities reported in India and Thailand. This is the first report on determination of Aspergillus spp. and AFB1 in imported wheat and barley grains in Penang, Malaysia.

“…Due to surplus maize in the market after harvesting, coupled with low prices, farmers mainly store their maize to take advantage of higher prices of their produce when the demand is high (Suleiman and Kurt, 2015). In most tropical countries, harvested grains are mainly stored by farmers for considerable periods in various types of storage structures made of mud, bamboo strips and plastic sacks (Bilgami and Sinha, 1987;Ranjan et al, 1992;Kumar and Kalita, 2017). These unimproved traditional storage methods inevitably provide suitable conditions for the growth of insects and microorganisms responsible for the quality loss in stored grains.…”

Maize weevil (Sitophilus zeamais Motschulsky) is a major maize (Zea mays L.) storage insect pest in the tropics which reduces the quantity and quality of maize hence facilitating establishment of aflatoxin and other mycotoxins. The objective of this study was to evaluate maize weevil resistance on selected inbred lines. Twenty eight inbred lines with 2 checks (MTPO701-reistant and Duma 41-susceptible) were used in this experiment. Thirty unsexed adult insects were introduced into 250 ml glass jars with grains of the lines at room temperature. Evaluation of weevil damage was done at 10, 60 and 120 days after maize weevil infestation. Each category of storage period was replicated 4 times and experiment was set at the same time. Data was collected on percent weevil damage, grain weight loss and number of live and dead weevils on each inbred line. ANOVA analysis showed significant differences (P ≤ 0.05) on weight loss. The selection of the resistant genotypes was based on percent weight loss after 60 days. Resistant lines selected included KEN2/TZL2.25# and LEPOOL-1/TZL2-2-1. These lines showed resistance to maize weevil damage and hence can be stored up to 4 months. At 120 days there was maximum damage and most lines could not be differentiated on the basis of resistance. KEN2/TZL2-2-5# showed consistency in resistance to maize weevils at all storage periods. High heritability at 60 days showed that selection for weevil resistance in these inbred lines is effective and feasible. Results in this study also revealed high, positive and significant correlation relationship between percent damage, weight loss and live weevils. The maize weevil resistant lines can be used to improve resistance of high yielding varieties in breeding programmes.
