    • Abstract

       

      The life history of sexuparae and sexual morphs of woolly apple aphid (Eriosoma lanigerum Hausmann) is reported from Simla Hills. Sexuparae are alate parthenogenetic viviparae and produce the sexuals (males and oviparae). The reproductive potential of sexuparae is much lower as compared to that of virginoparae. Sexuals are apterous and have degenerated mouth parts. An ovipara lays only one egg. All these morphs undergo four moults resulting in five instar stages.
