Abstract:
BACKGROUND: Mansonia mosquitoes transmit arboviruses to humans. This study describes the karyotypes and C-banding of Mansonia humeralis, Mansonia titillans, Mansonia pseudotitillans, and Mansonia indubitans.
METHODS: From the 202 larvae, the brain ganglia were dissected (n=120) for the preparation of slides. Twenty slides with well-distended chromosomes for each species (10 for karyotyping and 10 for C-banding) were selected for further study.
RESULTS: The haploid genome and the average lengths of the chromosomal arms differed in relation to the centromere between species, and intraspecific differences also occurred in the distribution of the C-bands.
CONCLUSIONS: These results are useful for better understanding of the chromosomal variability of Mansonia mosquitoes.
摘要:
背景:曼索尼亚蚊子将虫媒病毒传播给人类。这项研究描述了肱骨Mansonia的核型和C带,Mansoniatitillans,曼索尼亚假蒂蒂兰,还有Mansoniaindubitans.
方法:来自202个幼虫,解剖脑神经节(n=120)以制备载玻片。选择每个物种的20个染色体扩张良好的载玻片(10个用于核型分析,10个用于C带)进行进一步研究。
结果:物种之间的单倍体基因组和染色体臂的平均长度与着丝粒有关,种内差异也出现在C带的分布中。
结论:这些结果对于更好地了解曼索尼亚蚊子的染色体变异性很有用。
