“…Rahimi Namin et al [33] reported shorter durations of development of larvae, shorter longevities of female or male adults and higher values of the intrinsic or finite rate of increase when T. castaneum fed on different varieties of barley than the observed corresponding values of the current study on semolina. Although the experiments by Rahimi Namin et al [33] were conducted under the same temperature as in our study, relative humidity was higher (75% ± 5%). Howe [42] reported that relative humidity values > 70% accelerate the egg-to-adult development of T. castaneum on sieved grinded wheatfeed.…”

“…This fact has also been observed for T. granarium [16]. However, Rahimi Namin et al [33] found that there were significant differences in the development of T. castaneum female and male pupae among various varieties of barley. Given that differences were not constant for both sexes among the tested varieties it may be concluded that the lack of differences in our study and in the one of Kavallieratos et al [16] is due to the fact that the overall population of female and male pupae was analyzed.…”

“…For example, the khapra beetle, Trogoderma granarium Everts (Coleoptera: Dermestidae) exhibited 2.50-4.21, 2.79-5.51 or 3.36-4.71 times higher values of intrinsic rate of increase and 1.02-1.05, 1.03-1.07 or 1.04-1.05 when fed on different varieties of barley, hybrids of maize or grain commodities, respectively [16,40,41]. Rahimi Namin et al [33] reported shorter durations of development of larvae, shorter longevities of female or male adults and higher values of the intrinsic or finite rate of increase when T. castaneum fed on different varieties of barley than the observed corresponding values of the current study on semolina. Although the experiments by Rahimi Namin et al [33] were conducted under the same temperature as in our study, relative humidity was higher (75% ± 5%).…”

“…The fact that the authors used a different type of maize (hybrid "Pioneer 3320") from the one used in our tests could be a reason for the poor development of T. castaneum observed here. For instance, Rahimi Namin et al [33] reported that the time of development and the % survival of T. castaneum larvae or pupae, the longevity of adult females and males, and the fecundity varied significantly among ten varieties of barley. As far as it concerns cracked wheat, former studies have documented that progeny production of T. castaneum was lower than wheat flour and wheat bran [45] or barley and oats [46].…”

“…For instance, Li and Arbogast [32] examined how the condition (cracked vs. no cracked) of stored-maize affects the demography of T. castaneum. A recent exploration concerning the demography of T. castaneum infesting ten varieties of barley revealed that two of them were unsuitable for the pest's population growth [33]. Therefore, the aim of this study was to fill out the existing knowledge of the biology of T. castaneum by studying the suitability of semolina, cracked wheat and cracked maize as feeding commodities for this important stored-product insect.…”

In the current study it was investigated the suitability of semolina, cracked wheat and cracked maize as feeding commodities for the red flour beetle, Tribolium castaneum (Herbst) (Coleoptera: Tenebrionidae). The pest completed its development on all tested commodities. The developmental time of larvae was lower on cracked wheat (59.6 days) and cracked maize (54.6 days) compared to semolina (72.8 days). The developmental time of pupae did not differ significantly among tested commodities, ranging from 6.2 to 6.6 days. Female and male longevities were 70.9 and 77.1 days, 92.2 and 77.9 days and 177.0 and 183.7 days, when T. castaneum was fed on semolina, cracked wheat and cracked maize, respectively. The highest fecundity (28.7 eggs/female) was recorded when T. castaneum was fed on semolina, followed by cracked wheat (2.7 eggs/female) and cracked maize (1.2 eggs/female). The prolonged adult longevity, which was observed on cracked maize, may be attributed to the absence of the cost of reproduction, due to low fecundity on this commodity. The values of the intrinsic rate of increase were 0.014 and −0.021 females/female/day when it was fed on semolina and cracked wheat, respectively, while no demographic analysis was carried out for cracked maize due to high early larval mortality and low fecundity on this commodity. The net reproductive rate and mean generation time were 6.19 females/female and 127.5 days and 0.16 females/female and 91.9 days, when it was fed on semolina and cracked wheat, respectively. Based on demographic analysis, T. castaneum population growth is favored only on semolina. We expect semolina to act as a suitable commodity for T. castaneum, while cracked wheat and cracked maize allow only its survival by acting as alternative commodities. The estimated demographic parameters of T. castaneum on the tested commodities could be used as a useful tool to predict its population outcome in storage facilities.
