Gnawing activity, dietary carbohydrate deficiency and oothecal production in the American cockroach (Periplaneta americana)

  • D. E. Bignell


The gnawing activity of adult female cockroaches was assessed by the dry weight loss of cotton fibre supplied to individual insects. In animals maintained on a carbohydrate-deficient diet the use of fibre was significantly less than in animals receiving a balanced diet. A comparison with controls showed that under both dietary regimes access to a fibre source did not significantly increase the mean, total number of oothecae produced.
