The khapra beetle, Trogoderma granarium Everts (Coleoptera: Dermestidae), is a polyphagous pest that infests many stored grains and products. The effect of nine maize hybrids including 704, AR 89, AS 71, AS 77, BC 678, KSC 703, PL 472, SC 704, and Simax was studied on biology and life table parameters of T. granarium at controlled conditions (33 ± 1 °C, 65 ± 5% RH, and a photoperiod of 14:10 [L:D] h). According to the results of this study, the immature period was the longest on BC 678 (56.79 ± SE: 1.51 d) and the shortest on PL 472 (39.90 ± 0.48 d). The highest values of fecundity and fertility were observed on PL 472 (67.95 ± 1.23 eggs and 74.81 ± 0.68%, respectively) and the lowest values were on BC 678 (40.00 ± 1.63 and 48.24 ± 1.35, respectively). The net reproductive rate (R0) of T. granarium ranged from 10.40 ± 0.11 offsprings on BC 678 to 30.43 ± 0.20 offsprings on KSC 703. The highest intrinsic rate of increase (rm) was for T. granarium reared on KSC 703 (0.0773 ± 0.0001 d-1), and the lowest was on BC 678 (0.0390 ± 0.0002 d-1). According to the obtained results, BC 678 is an unfavorable hybrid for population increase of T. granarium, which can be recommended to be grown in regions where the damage of T. granarium is considerable to minimize maize infestations by this pest.
谷斑皮蠹（Trogoderma granarium Everts，鞘翅目：皮蠹科）是一种多食性害虫，会侵害多种储藏谷物及制品。研究了包括704、AR 89、AS 71、AS 77、BC 678、KSC 703、PL 472、SC 704和Simax在内的9个玉米杂交种对谷斑皮蠹在可控条件下（33±1°C、65±5%相对湿度、光周期14:10[光照:黑暗]小时）的生物学和生命表参数的影响。根据本研究结果，未成熟期在BC 678上最长（56.79±标准误：1.51天），在PL 472上最短（39.90±0.48天）。繁殖力和生育力的最高值在PL 472上观察到（分别为67.95±1.23枚卵和74.81±0.68%），最低值在BC 678上（分别为40.00±1.63枚卵和48.24±1.35%）。谷斑皮蠹的净繁殖率（R0）范围从BC 678上的10.40±0.11个后代到KSC 703上的30.43±0.20个后代。内禀增长率（rm）最高的是在KSC 703上饲养的谷斑皮蠹（0.0773±0.0001天-1），最低的是在BC 678上（0.0390±0.0002天-1）。根据所得结果，BC 678是不利于谷斑皮蠹种群增长的杂交种，可推荐在谷斑皮蠹危害严重的地区种植，以尽量减少该害虫对玉米的侵害。
