云南省烟蚜红绿2种体色生物型的差异

从形态学和生物学方面对云南省红绿2种体色生物型烟蚜进行了研究,并用类平均法对形态特征指标进行了聚类分析。结果表明：红色型有翅烟蚜和绿色型有翅烟蚜的体长、触角、额瘤、尾片及尾板等形态特征上存在显著性差异;红色型烟蚜的产仔量、寿命及生殖期均显著高于绿色型烟蚜;2种体色生物型烟蚜的种群增长曲线均为S型,红色型烟蚜的种群饱和时的密度较绿色烟蚜高,但自然反应时间较绿色烟蚜短。

Difference of Myzus periscae (Sulzer) between Red Biotype and Green Biotype in Yunnan Province

This paper studied the difference on the morphological and the biological of Myzus periscae (Sulzer) between red biotype and green biotype in Yunnan Province,it showed that there are significant difference of morphological mutant antenna, the frontal tuberde and the caudae of M. periscae between the red biotype and the green biotype on the corpus length. The cluster analysis showed M. periscae can be divided into two groups. The total fecundity per adult of the red biotype s is lager than the green biotype s and its longevity and reproductive period are all longer than that of the green biotype s. The population growth equations of two types fit for "S" curve. The red biotype s population saturation density is higher than the green biotype's while its natural reaction time is shorter.
