烟蚜茧蜂生物学研究Ⅲ──温度对成蜂体色的影响及某些形态特征的变异

Bionomics of Aphidius gifuensis Ashmead Ⅲ. The Effect of Temperature on the Adult Integmental Colouration and Variability of Some Morphological Characters

在不同温度条件下，烟蚜茧蜂成蜂胸部颜色可以由全部黄色变为全部黑色或黑褐色，而僵蚜壳颜色可由乳白或淡黄色变为黑褐色。此外，作者还对烟蚜茧蜂成蜂纯系后代一些常用的分类特征的变异进行了研究，结果表明其变异范围远较以往所描述者为大。

The integmental colouration of adult and mummied aphid of Aphidius gifuensisAshmead varied according to different rearing temperature. The colouration of thorax of adultsgipuensis varied from wholly yellow to black or light yellow to black brown. Somemorphological characters of progeny of one mated female, which commonly are used todistingush aphdius species, also were examined. The results showed that some characterswere more variable than those supposed previously.
