Abstract The cowpea weevil, Callosobruchus maculatus (F.) (Coleoptera: Chrysomelidae) is one of the most important storage pests of legume seeds. The effect of various legume species including chickpea (Cicer arietinum L.) (cultivars Hashem and Mansour), cowpea (Vigna unguiculata L.) (cultivars Mashhad and 1057), green gram (Vigna radiata L.) (cultivar Parto), lentil (Lens culinaris Medikus) (cultivar Bilehsavar) was studied on the life history and life table parameters of C. maculatus at 30 ± 1 °C, relative humidity of 65 ± 5% and complete darkness. The developmental time was longest on lentil and shortest on cowpea 1057. The fecundity (number of eggs laid per reproductive period) of the pest was the lowest on lentil. The longest oviposition period was observed on chickpea Hashem. The gross and net reproductive rates were the highest on chickpea Mansour and lowest on lentil. The intrinsic rate of increase and finite rate of increase were the lowest when C. maculatus was reared on lentil and highest when it was reared on other hosts. The longest and shortest mean generation times were observed on lentil and cowpea 1057, respectively. According to the obtained results, lentil was relatively resistant and the other tested legumes were more susceptible hosts for feeding and population increase of C. maculatus. It is concluded that the resistant host cultivar can be proposed to be incorporated into breeding programs to minimize the economic losses incurred by C. maculatus.

不同豆科植物种子对豇豆象甲（Callosobruchus maculatus (F.) (Coleoptera: Chrysomelidae)）生命表参数的影响

摘要 豇豆象甲 Callosobruchus maculatus (F.) (Coleoptera: Chrysomelidae) 是豆科植物种子最重要的贮藏害虫之一。包括鹰嘴豆 (Cicer arietinum L.)（栽培品种 Hashem 和 Mansour）、豇豆（Vigna unguiculata L.）（栽培品种 Mashhad 和 1057）、绿豆（Vigna radiata L.）（栽培品种 Parto）、扁豆（ Lens culinaris Medikus)（栽培品种 Bilehsavar）在 30 ± 1 °C、相对湿度为 65 ± 5% 和完全黑暗的条件下对 C. maculatus 的生活史和生命表参数进行了研究。小扁豆的发育时间最长，豇豆1057最短。该害虫的繁殖力（每个生殖期产卵数）在小扁豆上最低。在鹰嘴豆哈希姆上观察到最长的产卵期。鹰嘴豆曼苏尔的总繁殖率和净繁殖率最高，小扁豆最低。C. maculatus在扁豆上饲养时的内在增长率和有限增长率最低，在其他寄主上饲养时最高。分别在扁豆和豇豆 1057 上观察到最长和最短的平均世代时间。根据所得结果，扁豆具有相对抗性，而其他受试豆科植物是更易感的C. maculatus 取食和种群增加的宿主。得出的结论是，可以建议将抗性宿主品种纳入育种计划，以尽量减少 C. maculatus 造成的经济损失。maculatus 是在扁豆上饲养的，当它在其他宿主上饲养时最高。分别在扁豆和豇豆 1057 上观察到最长和最短的平均世代时间。根据所得结果，扁豆具有相对抗性，而其他受试豆科植物是更易感的C. maculatus 取食和种群增加的宿主。得出的结论是，可以建议将抗性宿主品种纳入育种计划，以尽量减少 C. maculatus 造成的经济损失。maculatus 是在扁豆上饲养的，当它在其他宿主上饲养时最高。分别在扁豆和豇豆 1057 上观察到最长和最短的平均世代时间。根据所得结果，扁豆具有相对抗性，而其他受试豆科植物是更易感的C. maculatus 取食和种群增加的宿主。得出的结论是，可以建议将抗性宿主品种纳入育种计划，以尽量减少 C. maculatus 造成的经济损失。
