ABSTRACT This study assessed the effect of drying on smoked horse mackerel fillets during storage at room temperature. Smoked horse mackerel (Trachurus trachurus) fillets were prepared by smoking brined horse mackerel fillets in a traditional improved kiln for 4 hours at 60 – 70oC. The fillets were later oven-dried at 65-70oC for 0, 2, 4, 6, and... Continue Reading

ABSTRACT Background: Myzus pe.rsicae (green peach aphids) are crop pests; they are among the most destructive insect pests on cultivated plants in temperate regions. Many of them are green in color, but others may be white wooly or black (McGravin,1993).Their damage to plants has made farming a complicated venture across the whole world. From the...
