A study of the biological features and the potential population growth between two laboratory strains of the confused flour beetle, Jacquelin du Val (Coleoptera: Tenebrionidae) from Greece and Serbia is conducted on cracked barley and cracked white rice. The results show that, at a species level, is able to complete development on cracked barley but not on cracked white rice. Therefore, cracked white rice proves to be an unsuitable commodity for . Larval development on cracked barley is significantly shorter for the Serbian compared to the Greek strain (37.7 and 49.7 days, respectively), but pupal development does not differ between the two strains (6.2 days for both strains). Additionally, male longevity does not differ between the Greek and Serbian strains (144.4 and 151.4 days, respectively), while female longevity is significantly shorter for the Serbian (151.7 days) compared to the Greek strain (186.6 days). Fecundity does not differ between the two strains (11.3 and 17.7 eggs/female for the Greek and the Serbian strain, respectively), whilst survival is higher for the Serbian strain on both tested commodities. The values of the net reproductive rate, the intrinsic rate of increase and the finite rate of increase on cracked barley are significantly higher for the Serbian (7.27 females/female, 0.025 female/female/day and 1.026, respectively) compared to the Greek strain (2.91 females/female, 0.014 females/female/day and 1.014, respectively). It therefore is expected that different strains of may exhibit variable phenology as well as potential population growth. Additionally, we expect our results to have bearing on the management of this species.
对来自希腊和塞尔维亚的杂拟谷盗（Jacquelin du Val，鞘翅目：拟步甲科）两个实验室品系，在碎大麦和碎白米上进行了生物学特性及潜在种群增长的研究。结果表明，在物种水平上，该昆虫能够在碎大麦上完成发育，但不能在碎白米上完成发育。因此，碎白米被证明是不适用于该昆虫的商品。与希腊品系相比，塞尔维亚品系在碎大麦上的幼虫发育显著更短（分别为37.7天和49.7天），但两个品系的蛹期发育没有差异（两个品系均为6.2天）。此外，希腊和塞尔维亚品系的雄性寿命没有差异（分别为144.4天和151.4天），而塞尔维亚品系的雌性寿命（151.7天）显著短于希腊品系（186.6天）。两个品系的繁殖力没有差异（希腊品系和塞尔维亚品系分别为11.3枚/雌和17.7枚/雌），而在两种测试商品上，塞尔维亚品系的存活率更高。在碎大麦上，塞尔维亚品系的净生殖率、内禀增长率和周限增长率的值（分别为7.27雌/雌、0.025雌/雌/天和1.026）显著高于希腊品系（分别为2.91雌/雌、0.014雌/雌/天和1.014）。因此，预计杂拟谷盗的不同品系可能表现出不同的物候以及潜在的种群增长。此外，我们期望我们的结果对该物种的管理有影响。
