摘      要：For capital-breeding insects,all resources available for adult metabolic needs are accumulated during larval ***,body size at adult eclosion represents the total energetic capacity of the *** female capital breeders,body size is strongly correlated with lifetime fecundity,while in males,body size,which correlates with fitness,is less *** capital-breeding species with wingless,flightless,or dispersal-limited females,flight potential for male Lepidoptera has important implications for mate-finding and may be correlated with body *** low population densities,failure to mate has been identified as an important Allee effect and can drive the success or failure of invasive species at range edges and in species of conservation *** capital-breeding European subspecies of Lymantria dispar(L.),was introduced to North America in 1869 and now ranges across much of eastern North *** ***,females are flightless and mate-finding is entirely performed by *** quantified male *** flight capacity and propensity relative to morphological and physiological characteristics using fixed-arm flight mills.A range of male body sizes was produced by varying the protein content of standard artificial diets while holding other dietary components *** length,a proxy for body size,relative thorax mass,and forewing aspect were all important predictors of total flight distance and maximum *** results have important implications for mate-finding and invasion dynamics in *** and may apply broadly to other capital-breeding insects.
