基于线粒体12S rRNA和ND5基因序列的中国飞蝗属3亚种系统发育关系研究

对分布于中国的飞蝗Locusta migratoria Linnaeus 3亚种的线粒体12SrDNA(487bp)和ND5(451bp)基因的部分序列进行测定,与已知全线粒体基因组全序列的非洲飞蝗亚种进行序列比较,并在此基础上对ND5基因,以斑腿蝗科瘤喉蝗Parapodisma mikado为外群,重建MP树。基于序列长度的限制,将两基因联合分析重建了1棵最简约无根树。在对准的4个亚种共有的481bp的12SrDNA和451bp的ND5片断序列比较中,AT含量明显高于GC含量。由序列差异来看,哑洲飞蝗和东亚飞蝗序列相似度高,非洲飞蝗和西藏飞蝗相似度高,ND5基因的MP树和联合树也支持这个结论。由于大陆漂移和青藏高原隆起的特殊地质事件,正好解释了非洲飞蝗和西藏飞蝗的相似性,支持西藏飞蝗为单独1亚种,与非洲飞蝗为同一起源地,与其它2亚种相区别。

Population control of the yellow‐spined bamboo locust,Ceracris kiangsu,using urine‐borne chemical baits in bamboo forest

The yellow‐spined bamboo locust, Ceracris kiangsu Tsai (Orthoptera: Oedipodidae), is a notorious defoliator of bamboos in China. In commercial bamboo forests, spraying insecticides to control C. kiangsu is neither convenient nor economic, therefore environmentally acceptable and cost‐effective methods are needed. Ceracris kiangsu adults are known to aggregate and gnaw at human urine‐contaminated materials; NaCl is a strong phagostimulant and NH₄HCO₃ is an attractant/arrestant. In the present paper, we found that foam plastic containers containing a blend of 0.03% bisultap, 3% NaCl, 3% NH₄HCO₃, and 0.1% Triton X‐100 (tetrad bait) had a powerful attracticidal effect and could kill a great number of especially female C. kiangsu adults, comparable to those containing a mixture of 0.03% bisultap and 5‐day‐incubated urine. In a field trial, the tetrad bait killed approximately 80% of females and about 9% of males in the treated plots after daily application for five consecutive days. The corrected average reduction rate was 48.2%. Moreover, the sex ratio was decreased from 1.18 before the trial to 0.25 after the experiment in the treated plots. These results indicated that there is the potential to develop a trap using NaCl as a phagostimulant and NH₄HCO₃ as an attractant that can be used for C. kiangsu control.
