概要

The wing form of Pteronemobius taprobanensis was influenced by a photoperiodic change. Macropterous adults were few in number either long-day (16L : 8D) or short-day (12L : 12D) conditions, but very common when there was shift in photoperiod from a long to a short one or vice varsa in the middle stage of nymphal development. The induction of the macropterous form by a short-day following 10 long-days after hatching was completed in about a week.
