ARAI, Tetsuo (Lab. Entomol., Fac. Agr., Hirosaki Univ., Hirosaki). 1978. Effects of group size on the wing form in Gryllodes sigillatus WALKER (Orthoptera : Gryllidae). Jap. J. Ecol., 28 : 263-267. Occurrence of the macropterous form in Gryllodes sigillatus WALKER was observed under various conditions of crowding and available area. When the available area was kept constant and the number of insects per container (=group size) was varied, the larger the group size the higher was the incidence of macropterous adults. When the available area was varied in proportion to the number of insects, the result showed a tendency similar to the above mentioned, even though the area per insect was the same. But when insects of the same group size were compared under different conditions of available area, the incidence of macropterous adults was similar in every case. It seems, therefore, that the occurrence of macropterous adults is under the control of the group size effect.
