Circadian Locomotor Activity Rhythms in the African Clawed Frog, Xenopus laevis: The Role of the Eye and the Hypothalamus
The effects of hypothalamic lesioning and removal of the eyes on locomotor activity rhythms of African clawed frog, Xenopus laevis were examined and freerunning periods in intact frogs were significantly shorter in dimLL than in DD.
Population Dynamics of Adult Spodoptera litura(FABRICIUS)(Lepidoptera:Noctuidae):Estimation of Male Density by Using Release-Recapture Data
Male density was estimated for revealing the reJationship between trap catch wlth synthetic sex pheromone and wild rnale density and showed generally similar, but smaller, fluctuation to the considerably overestimated prejections obtained by PETERsEN's method.
Population dynamics of adult Spodoptera litura (Fabricius) (Lepidoptera: Noctuidae): Dispersal distance of male moths and its seasonal change.
Dispersal distance traveled by male spodoptera litura and its seasonal change frorn May to September wereimated by releasing marked males and later recapturing them with sex pheromone traps, and the dispersal distance decreased during summer.
