| Abstract | ||
| A survey of insect species that infest eight grain crops at granary stores of Menoufia governorate along 2020-year months were conducted. Seasonal fluctuations of Sitophilus oryzae, and Oryzaephilus surinamensis infested peeled rice at three stores were determined. Furthermore, a control study was conducted to evaluate the effect of Sonchus oleraceus, and orange oil with Sodium chloride on the two insects. Sitophilus oryzae, Sitotroga cerealella,and Callosobruchus maculatus, were the most common primary insects, while O. surinamensis, and Tribolium castaneum was the most secondary insects, followed by Ephestia elutella, while Lasioderma serricorne, and Liposcellis subfuacus were found accidently. The results show that no infection was observed by S. oryzae and O. surinamensis during January& February. August month recorded 140 insects/ 1kg rice as the highest population of S. oryzae. Moreover, O. surinamensis, recorded the highest population in December as 150 insects/ 1 kg. The application of weed powder, decreased S. oryzae to 90% at the 1st month decreased to 70% & 40% for the 2nd and 3rd months, however, orange oil and table salt decreased the population to 100% in the 1st month, 99, 91,76, 66, and 53% in the next five months, respectively. While the application of weed powder decreased 90% of O. surinamensis after one month, decreased to 76% and 45%for after two and three months, however, the orange oil and NaCl decreased 100% of the population after one month, while it decreased by 91, 66,64,55, and 49% in the next five months. | ||
