  • Title: Sexual dimorphism in life history plasticity in the gypsy moth (Lymantria dispar L.).
    Author: Lazarević J, Perić-Mataruga V.
    Journal: Folia Biol (Krakow); 2003; 51(3-4):227-9. PubMed ID: 15303381.
    Abstract:
    Sexual differences in reaction norms of life history traits (larval development time--LDT, pupal weight--PW and adult longevity--L) were investigated in the gypsy moth reared on young or old oak leaves during the first larval instar. Sexual dimorphism was revealed for genetic variation in reaction norms that was expressed only for LDT in males, and PW and L in females. Higher mean plasticity of longevity was found in males compared to females indicating that the sexes are exposed to divergent selective pressures. Greater dependence of males on energy resources (carbohydrates and lipids) may account for the observed differences.
