The effect of genotype, environment, age and morph on morphological variation in alate Myzus persicae (Sulzer) (Hemiptera: Aphididae)
Published online by Cambridge University Press: 10 July 2009
Abstract
Six morphological variates were examined in fundatrigeniae and alienicolae of Myzus persicae (Sulz.) from four clones. In all clones, fundatrigeniae had significantly more abdominal tubercles, a relatively larger tubercle on segment 4, and relatively shorter cornicles than did alienicolae. Alienicolae reared on Chinese cabbage had significantly shorter hind femurs than those reared on potato, but otherwise there were no consistent differences between the two types. Mature fundatrigeniae did not differ consistently from young ones. The total number of abdominal tubercles was the most reliable character for distinguishing alate fundatrigeniae from alienicolae.
