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%.

“…Furthermore, the highest and lowest PWL indexes observed in the Albelad and Australia cultivars are consistent with those reported by Sayed et al [ 20 ], who suggested that grain weight loss was correlated with the number of F 1 progeny in wheat cultivars infected with Trogoderma granarium Everts and R. dominica . Moreover, Zulfikar et al [ 12 ] associated the increase in weight loss in wheat cultivars with an increase in the number of F 1 adults; insect numbers increased when wheat grains were stored, which resulted in grain weight loss. This may be attributed to the fact that durum wheat grains do not contain defense factors against insect infestation, unlike other plant tissues that contain defensive chemicals, such as phenols, saponins, and alkaloids.…”

“…Several parameters have been used to determine the susceptibility of stored crops to warehouse pests, with the susceptibility index being the most important. Different wheat varieties are susceptible to infestation by different warehouse pests at varying degrees [ 2 , 10 – 12 ]. However, to the best of our knowledge, there have been no studies regarding wheat cultivars resistant to O. surinamensis in Saudi Arabia.…”

The quality and quantity of wheat are severely affected by insect infestation during storage. Excessive use of chemical pesticides has resulted in several environmental issues, in addition to the emergence of pesticide-resistant strains. Extensive research has been conducted to determine sustainable alternatives, such as the selection and cultivation of insect-resistant crop varieties. The aim of this study was to determine the degree of susceptibility of four wheat cultivars, namely, Albelad, Aldwasair, Australia, and Najran (NJ), to Oryzaephilus surinamensis (L.) using four parameters: F1 progeny, length of developmental period, Dobie’s index of susceptibility (DI), and percentage weight loss (PWL). Albelad was highly susceptible (DI =17.44) to O. surinamensis, followed by Najran (DI =8.42) and Australia (DI =6.18) (susceptible and moderately susceptible, respectively), whereas Aldwasair was moderately resistant (DI =4.67). Furthermore, there were significant positive correlations between DI and the mean number of F1 progeny ( R 2 = 0.98) and between DI and grain weight loss ( R 2 = 0.95). However, a significantly negative correlation ( R 2 = −0.86) was observed between DI and beetle developmental period. These findings will aid the development of breeding programs to maintain the quality and quantity of wheat grains during storage.

W heat (Triticum aestivum) is the most dominant cereal crop in terms of cultivation and consumption all over the world (Ileke, 2011). Around 65-75% of Pakistan's entire wheat harvest is thought to be kept in storage or ware house (Zulfikar et al., 2020). Due to high amount of proteins wheat is considered as the most vital crop around the world (Ileke, 2011). Significant losses caused to stored wheat due insect pests (Strbac, 2002;Kavita, 2004). These pest insect pests are responsible for both quantitative and qualitative adverse effects on cereal crops (Fornal et al., 2007). The most frequently detected beetle pests in warehoused wheat grains with detrimental to the economy are, Rhyzopertha dominica (Bostrichidae: Coleoptera) which is a particularly harmful pest that infests all types of stored grains. The majority of this insect's whole life cycle passes inside grain kernels and where it feeds on the endosperm of grains (Rees, 2004;Edde, 2012) and another world's abundantly damaging insect pest of stored goods has been Abstract | The research experiment was conducted in the laboratory to check the efficacy of essential oils of two indigenous plant species i.e., colocynth, Citrulus colocynthis, and Akk, Calotropis gigantea by using different 03 and 06ml/L concentrations of each plant seed oil against the lesser grain borer, Rhyzopertha dominica, and Khapra beetle, Trogoderma granarium infesting wheat grains. Observations were made on mortality, weight loss, and insect damaged grain. The results show the maximum mortality 62.0% of R. dominica and 34.3% of T. granarium at a 6ml/L concentrations of C. colocynthis. While lower mortality 1.8% and 5.2% were recorded at 3ml/L concentrations of C.gigantea. Whereas, weight loss and insect damage to grain were observed higher 28.3% 27.6% when wheat grains were treated with C. colocynthis on both pests. However, miminum weight loss and insect damaged grain 1.06%, 7.06%, and 2.0%, 12.1% were obtained when wheat grains were applied 3ml/L concentrations of extracted C. gigantea oil. Thus, it is concluded that colocynth extracted oil as most effective essential oil to protect wheat grains.
