Susceptibility of some Rice Varieties to the Lesser Grain Borer, Rhyzopertha dominica Fab. (Coleoptera: Bostrichidae) in Benin

Comparison of Life Table Parameters and Digestive Physiology of Rhyzopertha dominica (Coleoptera: Bostrichidae) Fed on Various Barley Cultivars

“…Our results reveal that, in addition to its impacts on developmental time, the various barley cultivars also influences the age-stage specific survival rate of the lesser grain borer, demonstrating that the highest and lowest survival rate of immature stages were recorded on cultivars Mahoor and Dasht, respectively. Similar results were observed by Chougourou et al (2013) , with R. dominica reared on some rice varieties.…”

“…Probably, the variation in r m values of insects reared on the different barley cultivars resulted from chemical and physical differences between the cultivars. A higher population of R. dominica on cultivar Mahoor can increase their damage (number of damaged grains and weight losses) on this cultivar, as reported by Chougourou et al (2013) . They found that NRICA8 and NERICA10 had the highest percentage of weight losses as they did with R. dominica population during 2 and 3 mo of storage.…”

“…Several studies have indicated that the various cultivars of grains influence development, longevity and reproductive variables of stored-product pests ( Chougourou et al 2013 , Borzoui and Naseri 2016 , Naseri and Borzoui 2016 , Golizadeh and Abedi 2017 ). The results of present study suggest that R. dominica fed on the 12 barley cultivars tested is able to complete its development period and reproduction at the different rates.…”

“… Toews et al (2000) studied the resistance of eight U.S. wheat cultivars to R. dominica , and reported that cultivar Newana was the most resistant to this pest. Also, Chougourou et al (2013) studied the susceptibility of some rice varieties to the lesser grain borer and reported that the lowest growth of R. dominica population was on cultivar WAB56-104. Toews et al (2001) found that physical and chemical parameters of seeds can strongly influence the progeny of R. dominica on wheat cultivars.…”

Susceptibility of maize genotypes to Rhyzopertha dominica (F.)

“…A correlation between cracked and split hulls and susceptibility was observed (Chanbang et al 2008a, b;Kavallieratos et al 2012), and varieties with thicker hulls have been shown to be more tolerant (Chanbang et al 2008a). Moreover, a work conducted on African varieties has established that hardness and husk protection can confer tolerance to R. dominica (Chougourou et al 2013), while the work of Astuti et al (2013) conducted in Indonesia has shown that high phenolic content and hardness can increase resistance to R. dominica infestation. In wheat, susceptibility is negatively correlated with kernel hardness and is instead positively correlated with the percentage of total protein (Watts and Dunkel 2003).…”
