| 为明确寄主植物对黄脊竹蝗Ceracris kiangsu生长发育及取食选择的影响, 采用毛竹Phyllostachys edulis、苦竹Pleioblastus amarus、大叶箬竹Indocalamus tessellatus、铺地竹Pleioblastus argenteostriatus和靓竹Sasaella glabra f. albostriata单寄主饲养黄脊竹蝗初孵若虫至成虫, 分别测定取食5种竹子的黄脊竹蝗1~5龄若虫和成虫的死亡率，若虫的发育历期，成虫的体重和寿命, 并测定了黄脊竹蝗不同发育阶段对5种竹子的取食选择。结果表明, 黄脊竹蝗1、2龄若虫取食大叶箬竹的死亡率最高; 3~5龄若虫取食铺地竹的死亡率最高, 尤其是4、5龄若虫死亡率显著高于取食其余4种寄主；成虫期取食5种竹子的死亡率则无显著差异; 黄脊竹蝗若虫取食不同竹子的总发育历期存在显著差异, 其中取食毛竹的发育历期最短。发育至成虫后, 毛竹处理组的黄脊竹蝗雌、雄成虫体重均为最高, 靓竹处理组雌虫体重最低, 铺地竹处理组雄虫体重最低, 两处理组成虫体重均显著小于毛竹处理组; 取食5种竹子的黄脊竹蝗雌、雄成虫寿命均无显著差异。取食选择试验结果显示, 黄脊竹蝗若虫阶段对不同寄主的取食选择存在显著差异, 对毛竹的选择率明显高于其余寄主, 但进入成虫期后, 对各个寄主取食选择率差异不显著。本研究表明, 5种竹子对黄脊竹蝗的死亡率、发育历期、体重及若虫取食选择有显著影响, 黄脊竹蝗在5种供试竹子上均能完成生长发育, 但在毛竹上的适应性较好, 对其个体发育有利。 |

| To determine the effects of host plants on the development and feeding preference of Ceracris kiangsu, we studied the effects of feeding on five bamboo plants, including Phyllostachys edulis, Pleioblastus amarus, Indocalamus tessellatus, Pleioblastus argenteostriatus and Sasaella glabra f. albostriata, on the mortality, developmental duration, the lifespan and weight of C. kiangsu, and tested the feeding preference of the C. kiangsu at different developmental stages. The 1st- and 2nd-instar nymphs feeding on I. tessellatus showed the highest mortality, and the 3rd- to 5th-instar nymphs feeding on P. argenteostriatus had significantly higher mortality, especially the mortalities of the 4th- and 5th-instar nymphs were significant higher than that on the other four host plants, but there were no significant differences in mortalities of adults. The nymphal developmental duration was significantly different when the C. kiangsu was reared with different test plants, and the developmental duration of the nymph feeding on P. edulis was shortest. The weight of C. kiangsu female and male adults feeding on P. edulis was the heighest. The lowest body weight of female and male adults was observed in the S. glabra f. albostriata treatment and the P. argenteostriatus treatment, respectively, both of which were significantly lower than that in the P. edulis treatment. The adult lifespan (female and male) of C. kiangsu showed no significant difference when they were reared with different bamboo plants. The results of the feeding preference experiments showed that C. kiangsu nymphs were significantly different in their feeding preference to different host plants, exhibiting a preference for P. edulis. However, C. kiangsu adults showed no significant feeding preference among the five bamboo plants. In the present study, we found that different bamboo plants had a significant influence on the mortality, developmental duration, weight and nymphal feeding preference of C. kiangsu. It was able to complete growth and development on each of the five bamboo plants successfully, but preferred to feed on P. edulis, which was beneficial to individual development and reproduction. |
