Different cereal grains affect demographic traits and digestive enzyme activity of Rhyzopertha dominica (F.) (Coleoptera: Bostrichidae)

Distance-based Decision-making in Oviposition byTribolium castaneumHerbst (Coleoptera: Tenebrionidae) on Low- and No-gluten Flours

“…Meanwhile, Borzoui et al (2018) showed how important carbohydrates and proteins are in a given diet, as both of these dietary components affect the digestive response in α-amylase isoforms in the midguts of P. interpunctella . R. dominica also showed changes in amylolytic activity depending on whether they fed on foods that induce high amylolytic activity, such as maize, or foods that induce low amylolytic activity, such as sorghum or barley (low activity) (Naseri and Majd-Marani 2022). Altogether, these studies show the importance of nutrition and diet on stored product pest survival and reproductive success, as well as how variable these food resources can be.…”

“…T. castaneum is one of the most important pests of wheat flour and has also been used to explore questions of infestation risk in alternative flours, as well as to understand nutritional components associated with highest success rates of population growth (Sokoloff et al 1966, Wong and Lee 2001, Arthur et al 2020, Gerken and Campbell 2020, Naseri and Majd-Marani 2022). As a secondary pest of stored products, T. castaneum is cosmopolitan (Good 1936) and can result in food contamination and secondary damage via quinones and frass deposition (El-Mofty et al 1989, El-Mofty et al 1992, Hubert et al 2018).…”

Population development ofRhyzopertha dominica(F.) (Coleoptera: Bostrichidae) on different stored products

“…After ovipositing, the beetles were removed, and newly laid eggs were collected from the culture (50 eggs for each stored material). The eggs were carefully transferred into Petri dishes (60 mm in diameter, 15 mm in height) containing 10.0 g of each stored material (Naseri & Majd‐Marani 2022). All eggs were checked daily, and the duration and survival rate of immature stages (egg hatching, larval, and pupal periods) were recorded.…”

“…Based on the survivorship and reproductive data, life tables for R. dominica were constructed according to the methods of Carey (1993) and Naseri and Majd‐Marani (2022). The life table parameters were calculated as follows: (i) net reproductive rate R 0 = ∑ l x m x ; (ii) intrinsic rate of increase ; (iii) finite rate of increase ; (iv) mean generation time T = ∑ xl x m x / R 0 ; and (v) population doubling time , where x represents the time interval in units per day, l x represents the population survival rate of R. dominica during the time x , which is the survival probability for a specific time, and m x represents the average number of female offspring produced by each female beetle.…”

Physicochemical Properties of Sugarcane Cultivars Affected Life History and Population Growth Parameters of Sesamia nonagrioides (Lefebvre) (Lepidoptera: Noctuidae)

“…Additionally, the bootstrapping with 100,000 replications was used to estimate the variances and standard errors of life history and population parameters [ 51 , 52 ], and the paired bootstrap test was used to compare the means [ 53 , 54 ]. The relationship between the physicochemical features of the tested sugarcane cultivars and S. nonagrioides oviposition preference and population parameters was evaluated by Pearson correlation test using the average data of variables [ 55 , 56 ]. A dendrogram by Ward’s method was drawn based on the oviposition preference, life history, and life table parameters of the insect reared on examined sugarcane cultivars using SPSS version 22.0 (IBM, Chicago, IL, USA).…”
