Figure 1. The effect of controlled food availability on the synchrony
of moulting in colonies of the German cockroach, Blattella germanica.
Each colony (A, B, C, and O) of 35 to 40 larvae hatched from a single
ootheca. Adults of colonies A, B, and C were outbred as indicated
for maximum viability. The production and subsequent hatching of oothecae
are indicated for the first ovipositional period only.
