The fitness costs associated with a multiple insecticide-resistant strain of German cockroach, Blattella germanica (L.), were investigated and compared with those of a laboratory susceptible strain (UCR). The resistant strain (Ryan) showed a longer nymphal development time, decreased adult longevity, and reduced fecundity than the susceptible strain (UCR). The implication of the findings on the evolution of insecticide resistance and its management is discussed.
