The Effect of Five Wheat Varieties on Khapra Beetle, Trogoderma granarium Everts (Coleoptera: Dermestidae) During Four Storage Months

Abstract

Abstract In the labs of the College of Agriculture at Tikrit University’s Plant Protection Department, we tested five different wheat types against the Khapra beetle, specifically Trogoderma granarium. This study examines the effects of four months of storage on the following variables: the rate of insect population growth, grain weight loss, and grain germination percentage. The wheat varieties included in the study are Rashid, Tammuz 2, Abu Ghraib, Iraq, and Ibaa9. The findings revealed that the five wheat varieties were distinct from one another in terms of their susceptibility to and resistance to the different stages of the Khapra beetle life cycle, as well as the total number of insects, the amount of weight lost from the grains, and the percentage of grains that germinated after four months of storage. The findings revealed that the five wheat types were diverse and distinct in terms of how susceptible or resistant they were to the Khapra beetle. Granarius trogoderma At Everts. In terms of recorded larval numbers, the Rasheed variety had the fewest at 89.00 and the Abu Ghraib variety the most at 248.83. Based on the study’s findings, the Abu-Graib variety had the maximum number of pupae at 34.08, while the Rasheed variety had the lowest number at 5.67. According to the study’s findings, the variety Abu-Graib had the highest average number of adults at 190.60, while the variety Tamooz 2 had the lowest at 106.67. Grain weight loss rates varied across varieties in the study; the greatest was 8.62 gm for the Ab-Graib variety, while the lowest was 4.02 gm for the Rasheed variety. The study also found that after four months of storage, the Tammoz 2 variety had the highest percentage of germination Seeds at 80.20 percent, while the Abu-Graib variety had the lowest percentage at 55.90 percent. The study also measured the total number of insects, grain weight loss, and grain germination percentage among the tested wheat varieties. The findings revealed that the five wheat types were diverse and distinct in terms of how susceptible or resistant they were to the Khapra beetle. Foreverts, Trogoderma granarium. With a maximum of 248.83 larvae and a minimum of 89.00 larvae, the Rasheed variety had the greatest documented number of larvae. Based on the study’s findings, the Abu-Graib variety had the maximum number of pupae at 34.08, while the Rasheed variety had the lowest number at 5.67. According to the study’s findings, the variety Abu-Graib had the highest average number of adults at 190.60, while the variety Tamooz 2 had the lowest at 106.67. Grain weight loss rates varied across varieties in the study; the greatest was 8.62 gm for the Ab-Graib variety, while the lowest was 4.02 gm for the Rasheed variety. Additionally, the study found that the Abu-Graib variety had the lowest germination percentage at 55.90% and the Tammoz 2 variety had the highest at 80.20%.
