Vitellogenesis in Austracris guttulosa (Walker) (Orthoptera, Acrididae) in tropical Australia
Australian Journal of Entomology 36 (3), 307-308
Abstract: In tropical northern Australia, vitellogenesis in Austracris guttulosa only occurs if two requirements are met: daylength exceeds 13 h and vegetation is green. During the dry season (April-September), daylength is short and vitellogenesis is inhibited regardless of vegetation condition. Daylength exeeds 13 h by mid October, and vitellogenesis begins by late October if there is green vegetation produced by recent rain. But it is often dry during October and vitellogenesis is delayed until it rains either in November or even December.
