Long-term population dynamics of the Indian meal moth Plodia interpunctella and its granulosis virus

1. Theoretical studies suggest that disease may play an important role in the population dynamics of insects, but there have been no long-term empirical studies that have examined this interaction in the absence of other important biotic and abiotic factors. 2. In the laboratory, three virus-free (VF) populations of Plodia interpunctella were compared with three virus-infected (VI) populations that were continuously exposed to a granulosis virus. Data sets lasted for between 10 and 17 generations. Census data of dead adults were collected twice weekly and spectral analysis of the data was used to complement the observed population fluctuations
