SUZUKI, Tadashi (Dep. Biol., Fac. Sci., Tokyo Metrop. Univ., Tokyo). 1978. Area, efficiency and time of foraging in Polistes chinensis antennalis PEREZ (Hymenoptera, Vespidae). Jap. J. Ecol., 28 : 179-189. Foraging activity for flesh of Polistes chinensis antennalis PEREZ (Hymenoptera, Vespidea) was investigated in the field. It was observed that the foraging areas of some colonies in the same field overlapped each other. Some foraging areas of workers of the same colony were overlapped but some were distinct in direction or distance from the nest. The size of the foraging area of a worker was about 120 m^3 on a featureless grassland. Foundresses tended to fly out of the nest in various directions while workers flew relatively in definite directions. The foraging efficiency in terms of the number of successful trips for flesh was larger for workers than for foundresses, but not so different in terms of time. The time taken for a single trip for flesh by workers was longer than by foundresses. This fact may be responsible for the difference in the foraging efficiency in terms of the number of successful trips and consequently in the fidelity of flight direction from the nest. Returns to the remaining flesh of female wasps were also observed.
