The mean values for normal 4th and 5th instar larvae are indicated by the large open circles. The curve con- necting these points is taken from Figure 1. (Truman, Riddifprd and Safranek, 1974). When larvae were starved at weights greater than 4 g, all eventually transformed into small but otherwise normal pupae. It was impossible to obtain viable additional larval instars by simple starvation of a final instar larva. 100 75 c OJ 50 Q. 25 0.
