摘要： 为了探讨双斑长跗萤叶甲取食几种主要农作物对成虫生殖力的影响， 在 25℃恒温条件下， 分别用大豆叶片、 玉米花丝、 玉米叶片、 水稻叶片、 棉花叶片、 马铃薯叶片和向日葵叶片等寄主组织饲养双斑长跗萤叶甲成虫， 观察其取食不同寄主组织的寿命和产卵情况。结果表明， 双斑长跗萤叶甲雌成虫取食不同寄主组织的寿命、 雌成虫产卵比例、 产卵量等均表现出显著差异。在供试寄主上雌成虫寿命和雌虫个体产卵比例由大到小依次为玉米花丝、 棉花叶片、 大豆叶片、 马铃薯叶片、 玉米叶片、 向日葵叶片和水稻叶片； 产卵量从大到小依次为棉花叶片、 玉米花丝、 大豆叶片、 向日葵叶片、 马铃薯叶片、 玉米叶片和水稻叶片； 产卵进度除取食马铃薯叶片表现为明显集中在前期外， 取食其余寄主组织的产卵进度均表现为相对均衡。在寄主玉米上， 取食雌穗花丝的产卵量显著高于玉米叶片。综合评价玉米、 大豆、 棉花和向日葵是双斑长跗萤叶甲成虫期较理想的寄主植物， 在农田生态系中是该害虫选择危害的主要农作物。

Abstract: To explore the adult oviposition of Monolepta hieroglyphica in several major crop hosts, adults of Monolepta hieroglyphica were reared with seven kinds of host plant tissues including soybean leaves, maize filament, maize leaves and so on under 25℃ constant temperature in the laboratory. The results showed that longevity, spawning rate and oviposition amount of adults which feed on different host tissues were significantly different. Adult longevity and spawning rate on host tissues from high to low was maize filament, cotton leaves, soybean leaves, potato leaves, maize leaves, sunflower leaves and rice leaves. The oviposition amount from high to low was cotton leaves, maize filanent, soybean leaves, sunflower leaves, potato leaves, maize leaves and rice leaves. And the processes of laying eggs were similar and steady in different host tissues except potato leaves in which the oviposition focused on early period. The oviposition amount on the maize filaments was significantly higher than that on maize leaves. These indicated maize, soybean, cotton and sunflower were the preferred host plants of M.hieroglyphica at the adult stage in farmland ecosystem..
